Description

[Detailed Description of the Invention] The present invention relates to a novel tea manufacturing method and tea processing device,
In detail, the temperature and volume of the hot air sent into the rolling chamber, the number of revolutions of the main shaft on which the rolling hands and dredges are attached, and the number of leaf-beating stops, which were previously considered to be difficult to operate even for experienced engineers. The transition of each control element in the tea manufacturing process, such as the position, is
The finishing quality level selected by the operator, or the ready-made pattern that has been set in advance in a manner that corresponds to the level of finishing quality that is further subdivided by raw leaf quality, or when a good product can be obtained by trial. The pattern is used as an indicator, and there is no need for a skilled technician to operate the rough rolling process himself, which is repeated continuously.Also, even if the rough rolling process is left to an unskilled person, the rough rolling process can be performed by a skilled technician. It is an object of the present invention to provide a new tea manufacturing and roughing method and a tea manufacturing and roughing device that can obtain a product as good as or better than the previous method and have a uniform quality.

The tea manufacturing process has the meaning of gradually drying the tea leaves steamed in the previous process with hot air until the residual moisture content of the tea leaves is about 50% without being crushed or stirred in a rolling chamber. The important point is to dry the leaves as carefully as possible without over-drying them while maintaining the leaf temperature around 36-37℃. This results in quality deterioration such as generation of grassy smell or stuffy smell.

Such a tea manufacturing and rough rolling process is generally performed as follows. That is, a main shaft is rotatably arranged in a rubbing chamber having a roughly cylindrical rolling barrel, and a rolling hand is attached to the main shaft to press the tea leaves against the rolling barrel and apply pressure, and a kneading hand is used to scrape up the tea leaves for stirring. The tea leaves that have undergone the previous process are immersed in the kneading chamber, and the main shaft is rotated to apply pressure and agitation to the tea leaves, and to supply hot air into the kneading chamber. This process gradually dries the tea leaves. The amount of tea leaves input into the rolling chamber, the temperature and amount of hot air supplied into the rolling chamber,
The best rough rolling can be achieved by appropriately controlling control elements such as the rotational speed of the main shaft, the position of the leaf stopper, and the position of the main shaft relative to the rolling cylinder.

However, in such a tea manufacturing process, it is difficult to know what temperature each control element, such as hot air temperature, should be at and how to change it as the process progresses. Needless to say, it is impossible to set a certain standard and process it uniformly. This is because tea is, so to speak, a living thing, and for example, there are differences in the time of picking, such as visible buds and stiff leaves, differences in the rarity of tea, differences in production areas, differences in annual rainfall, differences in sunshine hours, and the day before harvesting. The condition of fresh leaves changes slightly due to various conditions such as differences in weather, and furthermore, the condition of steamed leaves introduced into this rough rolling process changes variously depending on the steaming treatment in the previous process. This is because it is a thing.

Therefore, it is not necessarily the case that just because good results were obtained in the rough-rubbing process during the previous year or the previous harvesting, it is better to change the control elements in the same way in the rough-rubbing process this time. Sometimes you get good results, sometimes you don't. In addition, the tea making process is carried out in a battlefield-like atmosphere, and the opening of the airflow damper and the duration of the opening must be recorded every time the roughening process is in progress. not.

The same holds true for other control elements in the rough rolling process, such as the rotational speed of the spindle, the position of the spindle, etc.

From this point of view, during the tea manufacturing process, a skilled technician called a yakushi is always near the rough rolling machine and monitors the progress of the rough rolling process. The reality is that each control element, such as the change in hot air temperature, is controlled during the course of the rough-rubbing process, based on experience and intuition, with reference to the humidity level, etc.

Furthermore, even if a skilled engineer is always on hand to control the hot air temperature, etc., it is impossible to make the changes exactly the same, and it is undeniable that there will be slight differences in the results each time. .

The present invention has been made in view of these points.

In the present invention, a large number of ready-made patterns are prepared as indicators of the transition of control elements during the rough rolling process, and the user selects the - of the patterns by selecting the desired finishing quality level of the tea leaves. To provide a tea manufacturing and rough rolling method and a tea manufacturing and rough rolling apparatus having a plurality of rolling chambers in which one rough rolling process of each rolling chamber is completed while changing the control elements of each rolling chamber according to the selected pattern. The purpose is to

This allows even non-skilled technicians to carry out the rough kneading process without making any major mistakes. In other words, when selecting a pattern, are each control element and its transition related to finish quality? 31 Because they are intricately and subtly intertwined, it is difficult for even a skilled engineer to determine the specific process control values and select the appropriate pattern. Therefore,
It is helpful for workers to be able to select a desired level of finishing quality and then select a pattern that corresponds to that level (this can be done by creating a pattern that corresponds to each desired quality level through prior trials). This eliminates the trouble of thinking about the complex and delicate correlation between finish quality and control elements, and ensures a more reliable finish in the rough-rubbing process. Further, after selecting a pattern, each control element changes according to the pattern even if the operator is not near the roughing machine, and the operator does not need to touch the roughing process until the roughing process is completed.

Next, the present invention adds the quality of the tea leaves before they are introduced into the rough rolling process, such as fresh leaf properties and steaming mode, as elements for pattern selection, and in accordance with the pattern selected from this and the desired finishing quality level, each rolling chamber is It is an object of the present invention to provide a tea manufacturing method and a tea manufacturing and roughing device having a plurality of rolling chambers, in which the rough rolling process of one of the rolling chambers is completed while changing control elements.

This allows for more fine-grained pattern selection. In other words, even if the control elements change in exactly the same way in two different rough rolling processes, if the quality of the tea leaves before being introduced into the rough rolling process is different, tea leaves with different finished qualities will be obtained. It is. Therefore, considering the quality of the tea leaves before they are introduced into the rolling process as an element in pattern selection will help in selecting a more accurate pattern.

Further, the present invention selects a pattern by selecting a desired finish quality level, or by taking into account the setting of the quality of tea leaves before being introduced into the rough rolling process, and
The desired finish quality level of the first rubbing chamber is changed as needed during the progress of the process, and after the time of the change, the control elements of each rubbing chamber are newly selected by the level change in the first rubbing chamber. It is an object of the present invention to provide a tea manufacturing and rough rolling method and a tea manufacturing and rough rolling apparatus which have a plurality of rolling chambers and which can perform tea manufacturing and rough rolling according to a pattern.

Even if you select a pattern in advance and start the rough rolling process, there may be times when you look at the condition of the tea leaves during the process and decide that the finished quality is not as desired. It is necessary to correct the trajectory by changing the process control values of the elements. However, the correlation between finishing quality and control elements is complex and subtle, and it is difficult to suddenly determine how much the control elements should be modified. For example, if it is determined that the color will become a little too dark if the process continues as it is, the amount of hot air that has the most influence on the finished color may be reduced. However, the amount of hot air is also related to the tea temperature, and reducing the amount of hot air will result in lower tea temperature. Therefore, for example, it is necessary to increase the rotational speed of the spindle, which is most closely related to the tea temperature, to compensate for the drop in tea temperature caused by the decrease in the amount of hot air, so that the tea temperature does not drop. In this way, finishing quality and control elements do not have a one-to-one correspondence with each other, but each is intricately intertwined with multiple factors, so it is extremely difficult to make such course corrections. . For this reason, in the past, a skilled technician called a yakushi was always close to the rough rolling machine and monitored the progress of the rough rolling process. The transition of each control element during the coarse rolling process is controlled at all times by referring to the wetness level and relying solely on experience and patience. However, according to the present invention, patterns that have yielded good results are selected from patterns of the transition of each control element in the rough rubbing process that have been performed thousands or tens of thousands of times in advance, and If you match the finish quality of roughly rolled tea leaves, a pattern that takes advantage of the above correlation will automatically be selected by selecting the finish quality, and a skilled technician will not be able to keep up with it. In both cases, tea leaves with the desired finished quality level can be easily obtained.

Furthermore, the present invention provides for selecting an existing pattern by selecting a desired finishing quality level, or by adding to this the setting of the quality of tea leaves before being introduced into the rough rolling process,
The desired finish quality level for the rubbing chamber is changed at any time as necessary during the progress of the process, and the transition of the control elements of each rubbing chamber after the time of the change is determined by the newly selected pattern due to the level change in the rubbing chamber. At the same time, the transition of the control elements performed in the first rough-rubbing step is stored in the memory as a new user-created pattern, and the user-created pattern is used as necessary in subsequent rough-rubbing steps. A tea manufacturing and rough rolling method and a tea manufacturing and rough rolling apparatus are provided, which have a plurality of rolling chambers, in which the rough rolling process of one of the rolling chambers can be completed while reading out and changing each control element in each rolling chamber according to this pattern. The purpose is to provide.

This makes it possible to use patterns that yield good results as they are in the subsequent rough rolling process.
It helps to equalize and improve the quality of tea. In other words, it is very simple and clear that when performing rough rubbing operations in sequence, the same rough finish quality can be ensured by changing each control element in the same pattern as when the good result was obtained. V4
However, as mentioned above, the tea manufacturing process is carried out in an extremely hectic atmosphere, and the quality level, which is changed at any time during the rough rolling process by relying on the experience and patience of the pharmacist, is determined at the time of the change and at the time of the change. It is not possible to accurately remember the level etc. that you have changed, and you cannot tell whether the changes are good or bad until you see the results, so it is difficult to remember such changes in the midst of your busy schedule. Accurately memorize or record everything, etc.
There's no way it could be done. Therefore, according to the present invention, it is possible to easily reproduce a pattern that matches the properties of the tea leaves, which was finally obtained through repeated trial and error, and it is possible to easily achieve uniformity and improvement in quality. can.

Furthermore, as described above, the present invention provides a plurality of rubbing chambers, and the selection of a ready-made pattern can be carried out by selecting a desired finish quality level for each rubbing chamber, or by adding a rough rubbing process to this. This is done for each room by taking into account the quality settings of the tea leaves before they are introduced into the room, and the desired finish quality level is changed at any time as necessary during the process for each rolling room, and the quality level after the point of change is allowing the transition of the control element to be made in accordance with the pattern newly selected by the level change, and storing the transition of the control element performed in the first rough-rubbing step in a memory as a new user-created pattern; The user-created pattern is read out as necessary in the rough rubbing process that is repeated thereafter, and each control element is changed according to this pattern so that the first rough rubbing process can be completed, and the transition of the control elements in the first rubbing chamber is further controlled. Since it is possible to complete one rough kneading process while changing the control elements of each kneading chamber as a master, the control elements of multiple kneading chambers can be changed using the change of control elements in one kneading chamber as a master. can be done. Therefore, when rough rolling tea leaves under the same conditions in each rolling room, the transition of the control elements in the rolling room that yielded the best results can be applied to the other rolling rooms.
Contributes to uniformity and improvement of finishing quality.

The present invention will be described in detail below, but first, an example of a tea processing machine used to carry out the present invention will be described.

Tea leaves are immersed in this boule until it reaches a predetermined weight, and the lower door 14 is opened as shown by the two-dot chain line in FIG. When the tea leaves in the boule 13 are opened, the tea leaves in the boule 13 are thrown into a rubbing chamber composed of a rolling barrel 4 and a stirring chamber 10. In addition, in this steamed leaf boule 13,
Usually, a device for measuring the weight of tea leaves is attached. Reference numeral 15 denotes a wire mesh that covers the upper end exhaust port of the agitation chamber 10. 16.16

The opening/closing degree is adjusted by 'a, 17''b, and 1)1C.

Reference numeral 18 denotes a hot air guide formed on the rear side of the stirring chamber IO, and one end thereof communicates with the hot air outlet 19 of the hot air generator 2.

The hot air generator 2 includes a heat exchange section 20 and an air supply fan 21. The heat exchange section 20 includes a furnace cylinder 23 and hot air passages 24, 24, . Hot air generated in the furnace cylinder 23 by the burner 25 is arranged in a maze-like manner in the casing 22 through hot air passages 24.2.
4 and is discharged from the chimney 26.

Incidentally, the burner 25 is provided with, for example, two nozzles that generate different amounts of heat, although not shown.
By operating two nozzles in three ways: igniting two nozzles, igniting one nozzle, and igniting the other, the amount of heat can be increased by 3.
It can be adjusted in stages. Air is introduced from the outside directly or through a suitable filter by the air blowing fan 21, enters the casing 22 through the air blowing port 27 that communicates between the blowing fan 21 and the casing 22, and then enters the casing 22 through the hot air blowing port 19. The air is supplied into the wind guide 18 from the air. When the air passes through the casing 22, it comes into contact with the heated surfaces of the furnace tube 23 and the hot air passages 24, 24, . . . and is heated to become hot air. Then, this hot air passes through the hot air guide 18, and then from the hot air inlets 12, 12, . . . to the massaging chamber (4
-10). Although not shown, a damper for adjusting the amount of hot air whose opening/closing degree is controlled by a control motor 28 is arranged between the air supply fan 21 and the air supply port 27 .

The rough kneading process using the above-described rough kneader 1 is performed as follows. A predetermined amount of the tea leaves that have completed the steaming process are introduced into the steamed leaf boule 13, and the tea leaves are rubbed 11i by separating [14, 14] of the steamed leaf boule 13.
4 and a stirring chamber 10. The hot air generated by the hot air generator 2 is supplied into the kneading chamber from the hot air inlets 12, 12, . . . through the hot air 418. Then, the main shaft 7 is rotated, and the tea leaves are pressed and kneaded against the kneading bottom by the kneaders 8.8, . and,
The tea leaves are rubbed and agitated while coming into contact with hot air, gradually drying them and proceeding with the rough rolling process. The above operation is continued until the residual water content of the tea leaves reaches a predetermined value, and when the desired value is reached, the coarse rolling process is completed, the take-out Sakai 6 is opened, and the tea leaves are taken out onto the conveyor 29 below. , and is sent to the next discussion process.

As mentioned earlier, the tea manufacturing and rough rolling process described above has the significance of drying the tea leaves steamed in the previous process until the residual moisture content is reduced to approximately 50%, but the residual moisture content is simply reduced. It is not enough to reduce the amount to about 50%, but it must be done in a way that does not deteriorate the quality of the tea leaves, such as their color and aroma. In order to do this, each control element in the tea manufacturing process, such as the temperature of the hot air supplied to the rolling chamber, the amount of hot air, the rotation speed of the main shaft, the position of the leaf stopper, and the position of the main shaft, must be controlled during the first tea manufacturing and rough rolling process. The steps must be made sequentially as the process progresses. Therefore, the means by which these control elements are controlled in the tea manufacturing and roughening machine 1 will be explained using an example of the ti-making section.

First, the temperature of the hot air supplied to the massaging chamber is controlled by adjusting the combustion degree of the burner 25.

25' is a burner controller, which has a temperature sensor placed at an appropriate location in the hot air guide 18, detects the temperature of the hot air blown into the rubbing chamber, and controls the burner temperature based on the difference between this value and the target value at that time. The degree of burnup is adjusted, that is, one of three modes is selected: both of the two nozzles are ignited, only one is ignited, and only the other is ignited.

The amount of hot air supplied into the massaging chamber is determined by operating the motors 17 and 28, etc., which are the operating parts, and controlling the number of rotations of the air supply fan 21.
Adjust the degree of opening/closing of the exhaust volume adjusting dampers 16, 16, . It can be controlled by

The rotational speed of the main shaft 7 can be controlled by a main shaft drive section 5 shown in FIG. 3, which corresponds to the operating section thereof. 30 is a frame of the main shaft drive unit 5, and this frame 3
A reducer 31 is fixed on the 0, and this reducer 31
The output shaft (not shown) is the main one! It is linked to Ylth7 directly or via a universal joint. 32 is a reduction gear pulley, which is fixed to the input shaft 33 of the reduction gear 31. Reference numeral 34 designates a speed change base rotatably supported by the frame 30 at a portion 35, and a main shaft drive motor 36 is fixed onto the speed change base 34.

A variable diameter pulley 38 is attached to the output shaft 37 of the main shaft drive motor 36.
A V-belt 39 is installed between the variable diameter pulley 38 and the reduction gear pulley 32. This variable diameter pulley 38 is formed by two members whose grooves for suspending the belt are joined by elastic pressure means, and when the speed change base 34 rotates in the direction of the solid line arrow and the pulley 38 moves away from the other pulley 32. , the pressing force by the V-belt 39 acts between the two members forming the structure to widen the gap between them. As a result, the diameter of the groove in which the belt is hung becomes smaller. Furthermore, when the speed change base 34 rotates in the direction of the dotted arrow, the two members forming the groove move toward each other by the elastic pressure means, and as a result, the diameter of the groove increases. Reference numeral 40 denotes a speed change rod rotatably supported by the frame 30 at an intermediate portion 41. A sliding pin 42 is provided at one swinging end of the speed change rod, and this sliding pin 42 is slidably inserted into an elongated sliding hole 43 provided at the free end of the speed change base 34. engaged. The free end of the transmission base 34 is constantly pulled in the direction of the arrow by a spring 44. speed change rod 4
An elongated sliding hole 45 is formed at the other swing end of the 0. A control motor 46 is fixed on the frame 30 and swings the control rod 49 via a rotation transmission system 47 and a reduction gear 48.

A roller 50 is rotatably provided at the swinging end of the rod 49 to control the speed change rod 49.
is slidably engaged with the sliding hole 45 of.

When the control rod 49 is swung by the control motor 46, the speed change rod 40 is also swung, and as a result, the speed change base 34 is swung, and the groove diameter of the variable diameter pulley 38 is increased in accordance with the direction. , or made smaller again,
The rotation speed applied to the input shaft 33 of the reducer 31 via the pulley 32 is changed, and therefore the rotation speed of the main shaft 7 is changed.

Reference numeral 51 denotes a leaf stopper plate disposed approximately in the upper center of the stirring chamber 10 so as to traverse it in the longitudinal direction. The leaf stopper plate 51 is connected to the control motor 53 through links 521, 52, 52, and 52, and is rotated about a shaft 54 as shown by the two-dot chain line in FIG. It has become.

Then, depending on the position of the leaf stopper plate 51, the dredge 9.
9. The trajectory of the tea leaves that are picked up changes. That is, trajectories as shown by arrows (1) to (7) corresponding to the symbols (1) to (7) added to the symbol "51" of the leaf stopper plate in FIG. 4 are drawn. Then, as the trajectory changes from (1) to (7), the tea leaves fall directly below the main shaft 7, and the degree of rolling of the tea leaves increases.

Next, the details of the present invention will be explained in detail by arranging four tea milling machines 18 to 1d as shown in FIG. This is a case where a so-called microprocessor is used to automatically control only the temperature of hot air supplied to the rolling chamber, the amount of hot air, the rotational speed of the main shaft 7, and the position of the leaf-clamping plate.

(b) Then, if the tea leaves that have completed the previous rough rolling process have already been taken out from the rolling chamber, the question ``Has the taking out been completed?'' is ``Yes'', and each of the above switches 77 and 78 and the button 74
．． 75 and 76 are operated, "Was data selection performed?" becomes rYes, 1, and "What is the control method?" becomes individual, so the central processing unit CPU selects each switch and The data set or selected by the button is read, and a corresponding pattern is written from the memory EP ROM to the working area corresponding to the massage chamber in the memory RAM.

For example, the element type is "normal leaf" and the steaming mode is "normal steaming".
, set all desired quality levels to normal, that is, color level "4"
, softness level "7" and tea temperature level "4", a pattern as shown in FIG. 9 is selected. Further, if the color level is set to a slightly darker level "3" and the other conditions are the same as above, a pattern as shown in FIG. 10 is selected. Furthermore, if you change the softness level to "6" from now on, the 11th
A pattern as shown in the figure is selected.

(C) Thus, the CPU controls the transition of the control elements in each massage room according to the pattern written in the working area of each massage room in the above. First, the initial value supported by the usage pattern and the current control value detected by each sensor 85 to 88 of each control element in each massage room are compared, and if there is a difference, the value is adjusted to match the initial value. A signal corresponding to the value is sent to the control element operation section 25', 4.
6.17.53 Output to the drive circuit. Then, when the current control value of each control element reaches the initial value, a command to immerse the tea leaves is issued, the tea leaves are immersed into the kneading chamber, and the rough kneading time starts counting for the kneading chamber. In this way, rough rubbing is started when the current value of the control element reaches the initial value, so even if the closing command switch 81 is operated, as long as the current value of the control element does not reach the initial value. In this case, the tea leaves are not immersed into the rolling chambers, and coarse rolling is started sequentially between the rolling chambers starting from the tea leaves that reach the initial value.

Then, the current values of hot air temperature, hot air volume, spindle rotation speed, and leaf stopper position detected by each sensor 85 to 88 are read, and these are instructed by the pattern written in the working area. If there is a difference, a correction signal is sent to the operating units of the burner controller 25' and each control mocheter 46, 17, 53, etc. until the difference disappears.

In such a program, "Rough kneading time is over?" will be "N" until the rough kneading time set in rough kneading time setting device F1 has passed.
o'', the control elements such as the hot air temperature are repeatedly executed, and the values of the respective control elements such as the hot air temperature are changed one after another to the values determined by the established pattern at predetermined time intervals, for example, the values shown in FIGS. 9 to 11. It will continue to change.

In addition, in the case of 8 cases of Ki-Ni 2i, the changes in the values of tea manufacturing factors such as hot air temperature in the rough rolling process 1 are divided into 40 steps, and the rough rolling time setting device 71 is used to set the rough rolling time to 40 steps, for example.
When set to 0 minutes, the value of the hot air temperature isovolume control element is changed to the value shown in the next step every 40/40 minutes.

(d) Then, the time set above, for example, 4
When 0 minutes have elapsed, "Rough kneading time is over?" becomes rYEsJ, and an ejecting operation command is issued to the automatic ejecting device (not shown), such as opening the ejecting door 6, and the buzzer 65 sounds, indicating that the rough kneading process is over. Notify the end.

When the take-out door 6 opens, the take-out limit switch 82 operates in conjunction with this, which initializes the current value of each control element to the initial value indicated by the pattern. depend on,
The machine is in a standby state, as if waiting to start the rough-rubbing process again.

Even if the start time of such an operation is different for each massage room, the value of each control element is individually changed from the beginning of the established pattern.

(2) The control elements were changed according to the initially selected pattern, but as a result of sampling the tea leaves during the rough rolling process, it was determined that the finished quality level would not be as desired.

(a) If it is determined that the finish quality is not as desired, press the selection button again. For example, for the first massage room, we initially started with the pattern shown in Figure 9, but as a result of sampling midway through, if we determined that one color was likely to become a little lighter, the color would change from then on. Since it is sufficient to change the control elements so that the color becomes a little darker, press 74a of the finishing quality level selection buttons 74a. Thereafter, the control elements are changed according to the pattern shown in FIG. 10. For example, if the rough kneading time is set to 40 minutes and 14 minutes after the start of rough kneading, 74a3 of the finish color level selection buttons 74a is pressed.
Figure 9 written in the working area of the first massage room,
The unexecuted part of the pattern, that is, after the 15th step, is the first
It is rewritten to the pattern after the 15th step of the pattern shown in figure O.

In this state, the process was proceeding, but when sampling was performed again, it was determined that the "softness" was likely to be a little harder this time. In that case, press 75a6 of the softness level selection buttons 75a. Thereafter, the control elements are changed according to the pattern shown in FIG. For example, if the level selection button 75a6 is pressed 25 minutes after the start of rough kneading, the unexecuted portion of the pattern written in the working area of the first kneading room, that is, the 26th step and subsequent steps, is the 26th step of the pattern in FIG. It can be rewritten as after the step.

(b) Thereafter, if there is no need to change, rough rubbing will be performed using the pattern shown in FIG. 11 up to 40 steps.

In the above example, as a result, the control elements in the first massage room are transitioned using the pattern shown in FIG. 12, and the working area of the first massage room is also A pattern as shown in FIG. 12 will be written.

If you get good results by reselecting the finish quality level mid-way through rough rolling, you can use that pattern in the subsequent rough rolling process. Similar results should be obtained if the conditions of the tea leaves introduced are the same. Therefore, when the tea leaves in the same state as the tea leaves introduced into the rough rolling process are subsequently roughened in the rolling chamber and other rolling chambers, the pattern may be used as a master.

(3) In the above example, when the pattern written in the working area of the first kneading chamber (the pattern as shown in FIG. 12) is used as a master to perform rough kneading in the other kneading rooms as well.

(a) Set the control method selection switch 68 to "1st" of "Master". As a result, the circuit is configured so that only the working area corresponding to the massage chamber designated as the master, in this case the first massage chamber, is used, and the changes in each control element such as hot air temperature in all massage chambers are The massage is performed using the pattern of the master massage room as an index. Of course, in the case of operation using the master pattern, as in the case of "individual massage room" described above, even if the start time is different for each massage room, the transition of each control element can be individually followed from the beginning of the master pattern. It is done.

Therefore, if you use the pattern of a massage room that has already been tried and obtained good results as a master, each control element of the other massage rooms will operate exactly the same as that of the massage room that has obtained good results. Become.

(b) Press the input command switch 81a.

(C) As a result, when the current value of the control element in the first rolling chamber reaches the initial value defined in the master pattern, tea leaves are introduced into the rolling chamber and the coarse rolling process is started.

(d) If the input command switches 81b to 81d are pressed for the massaging chambers other than the master massaging chamber, tea leaves will be immersed starting from the one whose current value of the control element has reached the initial value determined in the master pattern. Then, rough rubbing begins.

(e) Then, the control elements are changed in accordance with the master pattern for each rolling chamber, and when the rough rolling is completed, the tea leaves are taken out and initialized as described above.

In addition, such an operation using a master pattern can be carried out by an experienced person in an existing kneading room where the rough kneading process is proceeding without adjusting the finish quality level as described above. This can also be done by changing each control element.

That is, for example, if the rolling chamber of the first rough rolling machine 1a is used as the master, the finishing quality level selection button is operated while sampling the rolling chamber of the first rough rolling machine 1a, and as a result, as shown in FIG. If the control elements are changed according to the master kneading chamber pattern, the control elements will be changed in accordance with the pattern of the master kneading chamber for the other kneading chambers of the other rough kneading machines 1b to 1d.

The operations for each control method have been described above, but in the case of this embodiment, the memory RAM is backed up by a battery, and data is saved even if the power switch 64 is turned off.

Therefore, for example, if the results of the transition of each control element in the rubbing chamber of the first rough rubbing chamber 1311a are good and it is a pattern that you want to continue to use, for example, set the control method selection switch 68 to the first master and save the pattern. Store area designation button that corresponds to the store area number you want to store, for example 6
7b, set the load/store switch 68, and move the load/store switch 70 to the "Record J" side. With this operation, the pattern in the working area for the rubbing chamber of the first roughing machine 1a is stored in the store area N002 of the memory RAM.
The buzzer 65 sounds when the transfer is completed. Other massage room patterns can be saved in the same way.

When trying to change the temperature of each control element, such as the hot air temperature in the rubbing chamber of the second roughing machine 1b, using the pattern stored in the store area as an index, the pattern to be used as the index is Press the store area designation button, for example 67b, corresponding to the stored store area number, and set the control method selection switch 68 to "2nd" indicating the massage room to be changed according to the pattern.
Flip the load store switch O to the "call" side. As a result, the pattern of the working area is transferred to the working area of the selected massage room, and the buzzer 65 goes off to indicate that the pattern is completed. Then, when the rough kneading process of the kneading chamber is started, each control element of the kneading chamber changes using the pattern as an index.

Moreover, it is of course possible to use the pattern called up from the store area in this way as a master pattern. For example, in the above example, if the pattern stored in the second store area (specified by the button 67b) is to be called up to the working area corresponding to the rubbing chamber of the second roughing machine 1b and used as the master, the control Set the method selection switch 68 to the "master" or "second" position.
Then, by turning on the input command switches 81a to 81d for each kneading chamber, the rough kneading process is performed in the same manner as in the case of the master operation described above.

In addition, in the above explanation, each of the four rolling chambers is explained as one for each independent roughing machine, but it is also possible to use a single roughing machine with multiple rolling chambers. Of course.

Furthermore, control elements that can be controlled by the present invention include, in addition to those mentioned in this specification, those that affect the quality of tea leaves in the rough rolling process.
