Description

[Detailed Description of the Invention] The present invention relates to a novel method for rolling tea and a rolling device for tea manufacturing,
In detail, we will examine various control elements in the tea rolling process, such as the temperature of the hot air supplied to the rolling chamber, the rotation speed of the fan, and the rotation speed of the rotary drum, which were previously difficult to operate even for experienced engineers. When a good product can be obtained by using a ready-made pattern that has been set in advance to correspond to the finishing quality level selected by the operator or subdivided by raw leaf quality, or by trial. This pattern is used as an indicator, and it is not necessary for skilled technicians to directly operate each control element during the continuously repeated rolling process, and even if unskilled personnel are entrusted with carrying out the rolling process, they will still be skilled. It is an object of the present invention to provide a new method for rolling tea and a tea rolling apparatus capable of obtaining a product of good quality similar to that obtained by an engineer and making the quality uniform.

, The middle rolling process of tea manufacturing consists of rough rolling 1. After the rolling process, the tea leaves, which have a residual water content of approximately 47%, are lightly rolled using a rotating drum and rolling hands.
While applying pressure and massaging the inside, the internal moisture oozes out to the surface and the hot air evaporates the moisture, reducing the residual moisture to an average of 3.
It has the meaning of drying the tea leaves until it becomes 0%.

Such tea rolling process is generally performed as follows. That is, a rotary drum is rotatably supported on a frame, a main shaft is rotatably disposed within the rotary drum, and a large number of kneading hands are arranged for pressing and kneading tea leaves with the main shaft against the inner peripheral surface of the rotary drum. The tea leaves sent from the previous process are put into the kneading chamber configured as described above, and the barrel and main shaft are rotated 10 times to apply pressure and agitation to the tea leaves, and at the same time, the electric fan is rotated to perform the kneading process. By suctioning and discharging the hot air in the room, new hot air is supplied into the kneading chamber to gradually dry the tea leaves. The kneading pressure on the tea leaves, the temperature of the hot air supplied into the kneading chamber as the tea leaves dry, the fan f@machine rotation speed,
Each tea manufacturing element in the tea manufacturing and rolling process is changed, such as by lowering the rotational speed of the barrel, and when the tea leaves have undergone the desired shaping and drying, they are taken out and transported to the next fine rolling process.

In such tea manufacturing and rolling process, each tea manufacturing element, for example,
It is not clear how the rotational speed of the rotary cylinder should change, that is, what the rotational speed should be, and how it should change as the process progresses. I can't say that because tea is a living thing, so for example,
Due to differences in various conditions, such as differences in the time of plucking, differences in tea varieties, differences in production areas, differences in annual rainfall and sunshine hours, and differences in the weather the day before the day of picking, the quality of fresh leaves varies. This is because the condition of the tea leaves changes slightly, and furthermore, the quality of the raw tea leaves introduced into this medium rolling process varies depending on the quality of the rough rolling and rolling processes in the previous process.

Therefore, it is not necessarily the case that just because good results were obtained in the mid-rolling process during the previous year or the previous harvesting, it would be better to change each control element in the same way in the current mid-rolling process. Sometimes it comes out, sometimes it doesn't.

From this point of view, during the tea manufacturing and rolling process, a skilled technician called a pre-roller is always by the side of the rolling machine and monitors the progress of the rolling process. The reality is that each tea manufacturing element, such as the rotational speed of the rotary drum, is controlled during the middle rolling process, based on experience and intuition, with reference to wetness and other factors.

However, even if a skilled technician is always on hand to control each control element, if the temperature of the tea leaves is high during the process, for example, if you adjust it by slightly lowering the temperature of the hot air, it will affect the temperature. Each control element in the tea rolling process has a complex influence on the quality of the tea leaves, and the softness of the tea leaves, which was originally intended to be left as is, decreases. However, its operation is quite difficult.

In addition, even if a skilled technician is nearby to perform the operations and obtain good results, the tea manufacturing process is carried out in an atmosphere similar to a battlefield, and the process is subject to change at any time during the rolling process. It is impossible to record the transition of each control element point by point so that it can be repeated again when good results are obtained, and even if a skilled engineer is nearby and changes each control element, it is impossible to record the transition. It cannot be denied that they cannot be made exactly the same, and there are subtle differences in the finish each time.

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

The present invention prepares a large number of ready-made patterns that serve as indicators of the transition of control elements during the rolling process, and allows the user to select the - of the patterns by selecting the desired finishing quality level of the tea leaves. To provide a tea manufacturing and intermediate rolling method and a tea manufacturing and intermediate rolling apparatus having a plurality of tea rolling chambers, in which the intermediate rolling process of one of the rolling chambers is completed while changing the control elements of each rolling chamber according to a selected pattern. With the goal.

This allows even non-skilled technicians to perform the medium rolling process without making any major mistakes. In other words, as mentioned above, each control element and its transition are intricately and subtly intertwined with each other in terms of finishing quality, so even a skilled engineer must determine the specific process control value and change each control element accordingly. It is quite difficult to do so. Therefore, by selecting a desired level of finishing quality, it is possible to select a corresponding pattern (this can be done by creating a pattern corresponding to each desired quality level through preliminary trials). This frees the operator from the trouble of thinking about the complicated and delicate correlation between finish quality and control elements, and also ensures a more reliable finish in the middle rolling process. Moreover, after selecting a pattern, each control element is automatically changed according to the pattern, and the operator does not need to touch it at all.

Next, the present invention adds the raw leaf quality of the tea leaves before being introduced into the medium rolling process, such as fresh leaf properties and steaming mode, as elements for pattern selection, and each rolling process is performed according to a pattern selected from this and the desired finishing quality level. It is an object of the present invention to provide a tea manufacturing method and a tea manufacturing medium rolling apparatus having a plurality of tea rolling chambers, in which the medium rolling process of one of the rolling chambers is completed while changing the control elements of the chambers.

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 rolling processes, if the raw quality of the tea leaves before being introduced into the rolling process is different, tea leaves with different finished qualities will be obtained. This is because it will be done. Therefore, considering the quality of the raw tea leaves before they are introduced into the rolling process as an element in pattern selection helps in selecting a more accurate pattern.

In addition, the present invention selects a pattern by selecting a desired finish quality level or by taking into account the setting of the quality of the raw tea leaves before being introduced into the medium rolling process, and The desired finish quality level is changed at any time as necessary during the progress of the process, and the transition of the control elements of each rubbing room after the point of change is made according to the pattern newly selected by the level change in the rubbing room mentioned above. It is an object of the present invention to provide a method for rolling tea during tea production and a rolling apparatus for making tea, which have a plurality of rolling chambers.

Even if you select a pattern in advance and start the 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, as mentioned above, the correlation between finishing quality and control elements is complex and subtle, and there is no one-to-one correspondence, and it is difficult to decide at once how much each control element should be modified. be. For this reason, in the past, a skilled technician called a yakushi was always by the side of the rolling machine and monitored the progress of the rolling process, checking the progress of rolling the tea leaves, the feel of the tea leaves when they were squeezed, and the wetness. The course of the process control values of each control element during the middle rolling process is corrected by referring to the situation and relying solely on that experience and intuition. 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 middle rolling process that have been performed thousands or tens of thousands of times in advance, and Since the finish quality of the medium-rolled tea leaves is matched, the course can be accurately corrected even during the process, and tea leaves with the desired finish quality level can be easily obtained.

Furthermore, the present invention allows the selection of existing patterns to be made by selecting a desired finish quality level, or by adding to this the setting of the quality of the raw tea leaves before being introduced into the rolling process, 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 element B of each rubbing chamber is newly selected by the level change in the first rubbing chamber. At the same time, the transition of the control elements performed in the first rolling process is stored in the memory as a new user-created pattern, and the user can perform the process according to the pattern created by the user as needed in the middle rolling process that is repeated thereafter. Tea manufacturing method and tea manufacturing method having a plurality of rolling chambers, in which a production pattern is read out and each control element in each rolling chamber is changed according to the pattern to complete one intermediate rolling process in each rolling chamber. The purpose is to provide equipment.

As a result, patterns that have yielded good results can be used as they are in the subsequent rolling process.
It helps to equalize and improve the quality of tea. In other words, it is an extremely simple and clear logic that when performing sequential rolling operations, the same excellent finish quality can be ensured by making each control element change in the same pattern as when the good result was obtained. 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 first rolling process by relying on the experience and intuition of the pharmacist, does not change at the time of the change. It is not possible to memorize the level etc. accurately one by one, and it is also difficult to tell whether a particular change is good or bad until you see the results, so it is difficult to remember all the details about such changes in the midst of your busy schedule. Memorizing or recording accurately
There's no way it could be lateral. 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 system in which a plurality of rubbing chambers are prepared, and a ready-made pattern can be selected by selecting a desired finish quality level for each rubbing chamber, or by adding a medium-rubbing process to this. This is done for each rolling room by taking into account the quality settings of the tea leaves before they are introduced into the process, and the desired finishing quality level for each rolling room is changed at any time as necessary during the process. allowing the transition of the control element to be made according to the pattern newly selected by the level change, and storing the transition of the control element performed in the first rolling process in the memory as a new user-created pattern; The user-created pattern is read out as necessary in the middle kneading process that is repeated thereafter, and each control element is changed according to this pattern so that the first middle kneading process can be completed, and the control elements in the first kneading chamber are It is also possible to complete the middle kneading process by changing the control elements of each kneading chamber using the transition as the master, so the control in multiple kneading rooms can be performed using the transition of the control elements in one kneading chamber as the master. Elements can be transitioned.

Therefore, when performing medium rolling of tea leaves under the same conditions in each rolling room, the transition of control elements in the rolling room that yields the best results can be applied to the other rolling rooms, resulting in uniform finish quality. , contributing to excellence.

The present invention will be described in detail below, but first an example of a tea milling machine suitable for carrying out the present invention will be described.

FIG. 1 schematically shows a tea milling machine that constitutes a part of a tea milling machine equipped with a plurality of rolling chambers. In the figure, 1 is a frame, on which a rotary cylinder 2, an electric fan 3, and a driving device 4 are placed.The zero-rotating cylinder 2 is driven by the driving device 4 and rotates at an arbitrary rotation speed set by the user. It is configured to rotate, and its internal space is used as a massage chamber 5.

A main shaft 6 passes through the center of rotation of the rotary cylinder 2, and the main shaft 6 is also driven by the drive device 4 so as to rotate at an arbitrary rotation speed (approximately 1.5 times that of the rotary cylinder 2) set by the user. It is being done. The main shaft 6 has many kneading hands 7.7,...

The protruding ends 11.11, . . . urge the kneading spatulas 8, 8, . Further, the electric fan 3 is also driven by a drive device 4, rotates at an arbitrary rotation speed set by the user, and sucks hot air in the massage chamber 5 and discharges it to the outside of the machine. 12 is a hot air generator. Inside the hot air generator 12, there is a furnace tube and a smoke tube that are heated by combustion gas from a burner 13, and air introduced by an air fan 14 is heated in contact with the furnace tube and smoke tube. on the other hand,
A separate outside air inlet is provided on the back of the hot air generator 12, and depending on the strength of the suction force of the electric fan 3, the air heated by the furnace tube and smoke pipe is mixed with the air sucked in from the outside air intake. The heated air becomes hot air at a certain temperature and flows into the massaging chamber 5 from the hot air supply port 16 provided in the end plate 15. Further, 17 is an input port, and 18 is a chute connected thereto. 19 is a take-out door.

The tea leaves introduced into the mixing chamber 5 through the chute 18 and the input port 17 are lifted up to a certain height by the rotation of the rotary JI 2, and then collapsed, which is repeated, causing the tea leaves to be stirred and The kneading spatula 8.8... is pressed against the inner surface of the rotary cylinder 2 and twisted. During the approximately 30 minutes from immersion to removal, each control element in the tea manufacturing and rolling process, such as the temperature of the hot air, the rotation speed of the fan 3, and the rotation speed of the rotary drum 2, controls the progress of twisting of the tea leaves. It changes in sequence depending on the condition and dryness. When a predetermined degree of rolling and dryness is reached, the take-out m19 is opened manually or automatically, and the tea leaves fall onto the vibrating conveyor 20 and are sent to the next fine rolling process.

In addition, the opening and closing of takeout #19 in this medium kneading machine is performed by operating an operating handle or a switch (not shown), a clutch mechanism is activated, the rotation of the rotary cylinder 2 is set to a low speed rotation, and the takeout is carried out by the takeout guide. When the roller of the door 19 is pushed and the lock of the take-out door 19 is removed, the rotary cylinder 2 rotates and the take-out door 19 turns downward, the take-out #19 opens under its own weight, and then rotates further and the take-out door 19 opens. The take-out door 5119 is closed by turning upward and closing the guide, and then the take-out door 19 is locked by the key guide.

Normally, this operation is repeated twice, and when the tea leaves have been removed, normal rotation is resumed.

The details of the present invention will be explained below regarding the four massage chambers 5a, 5b, 5c, 5.
d (in the case of one kneading chamber per machine as shown in Fig. 1, four medium kneading machines) are set as one group, and a so-called microprocessor is used to control the rotary cylinders 2a, 2b, 2c, and 2d of each control element.

It should be noted that the tea temperature is determined during the rolling process, and the finished quality of the tea leaves cannot be determined strictly by fj9 taste. However, if we consider the tea leaves to have a certain quality due to the tea temperature being controlled to a certain degree during the rolling process, it can still be seen as a type of finished quality, so tea temperature is also considered to be a finished quality here.

Each of these sensors 44, 46, 47 is connected to the gate latch control circuit 39 via gate circuits 42, 42, 42, respectively.

Next, FIG. 5 shows an example of a mechanism for controlling the rotational speed of the rotary drum 2 and the electric fan 3. As shown in FIG. In the figure, 48 is a driven shaft, which transmits rotational force to the electric fan 3 or the rotating body 2. 49

Rotate using the fulcrum as a fulcrum. As a result, the distance between the driven shaft 48 and the shaft of the drive motor 50 changes. For example, when the distance becomes longer than before, the V-belt 56 bites into the variable diameter pulley 51, and its movable side groove. The wall 57 is moved in the direction of the arrow in the figure. Therefore, the diameter of the variable diameter pulley 51 becomes smaller, and the rotational speed of the driven shaft 48 becomes smaller than the previous rotational speed.

Although the action of the hot air temperature control motor M, a=M, d is not shown, the motor controls the opening of a throttle valve provided in the supply path for, for example, heavy oil or gas supplied to the burner 13. used for adjustment.

In addition, as means for changing the rotation speed, known mechanical and electrical means can be considered, such as changing the gear ratio, replacing the pulley, and changing the drive motor itself to a variable speed motor. Various means can be considered to adjust the burn-up degree, such as using multiple nozzles with different diameters and switching these with a solenoid valve, or changing the combination to adjust the burn-up degree. By the way. Furthermore, in order to operate elements other than the control elements adopted in this embodiment, such as the spring pressure of the kneading spatula 8, 8, . . . , a mechanism and an electric circuit corresponding to the object are required. Therefore, the operation section for operating the control elements changes depending on the operation method and the object to be operated, and the operation section shown in this embodiment (relays #1 to #4, operation motors M, -M5, etc.) Electrical part, variable diameter pulley 51,
Mechanical parts such as control arm 53, motor mount 54, etc. are just examples.

Therefore, using such a circuit, the tea manufacturing and rolling process, which is performed by varying control elements such as hot air temperature, rotary drum rotation speed, fan rotation speed, etc., is carried out according to the flowchart shown in Fig. 4. .

(1) First, a case will be described in which the middle kneading process can be completed using only the initially selected ready-made pattern.

(a) First, set the control method selection switch 26 for each massage room individually. In addition, the element type setting switch 36 is set to match the mark indicating the fresh leaf properties of the tea leaves to be put into the rolling chamber, and the steaming mode setting switch 37 is set to the steaming mode that allows the tea leaves to be put into the rolling chamber to be steamed. Align with the marking that indicates. For example, if the leaves are normal in nature and have been steamed normally, the switches 36 and 37 are set as shown in FIG. Furthermore, the desired finish quality is selected using finish quality level selection buttons 33, 34, 35, such as "shape", "softness", "tea temperature", etc., provided for each kneading chamber.

(b) Then, if the tea leaves that have completed the previous medium rolling process have already been taken out from the rolling chamber, the question ``Has taking out been completed?'' is ``Yes'', and each of the above switches 36 and 37 and button 33
．． 34 and 35 have been operated, "Was the day/evening selection performed?" becomes "rYes", and 1. “What is the control method?” Since it depends on each massage room,
The central processing unit CPU reads the data set or selected by each switch and button, and writes a corresponding pattern from the memory EPROM into 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".
, all desired quality levels are set to normal, that is, shape level "4".
”, softness level “7”, and tea temperature level “4”, a pattern as shown in FIG. 6 is selected. Also,
If the softness level is set to "6", which is a little softer, and the other conditions are the same as above, a pattern as shown in FIG. 7 is selected. Furthermore, if the tea temperature level is set to "5" from now on, a pattern as shown in FIG. 8 will be 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 indicated by the usage pattern and each sensor 44.4
6. Compare the current values of the respective control elements of the massage chambers 5a to 5d detected in step 47, and if there is a difference, operate the control element in accordance with the signal in order to make it match the initial value. output to the operation motors M+, M2, and Ms of the section.

Then, when the current control value of each control element reaches the initial value,
A command to immerse the tea leaves is issued, and the tea leaves are thrown into the rubbing chamber, and at the same time, a count of the medium rolling time for the rubbing chamber is started. In this way, since the middle rubbing is started when the current value of the control element reaches the initial value, even if the closing command switch 40 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 introduced into the rolling chambers, and medium 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, rotary drum rotation speed, and fan rotation speed detected by each sensor 44, 46, and 47 are read, and these are written in the pattern written in the working area. If there is a difference, a correction signal is sent to the operation unit of each control motor M, M2, M3, etc. until the difference disappears.

In such a program, does the middle kneading time end until the middle kneading time set by the middle kneading time setting device 29 has passed? ” is “N”
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 to the values determined by the established pattern at predetermined times, for example, the values shown in FIGS. 6 to 8. It is progressed one after another.

In addition, in the case of this embodiment, the electric fan 3 in the first rolling process
The changes in the rotational speed of the rotation months 2a to 2d are divided into 32 steps, and if the medium rubbing time is set to, for example, 30 minutes with the medium rubbing time setting device 29, the electric fans 3a to 3d will be turned on every 30/32 minutes. The number of rotations of the 3d1 rotating drums 2a to 2d is changed to the number of rotations shown in the next step.

(e) Then, the time set above, that is, 30 minutes after the injection.
When the minutes pass, is the middle massage time over? '' becomes rYes4, and an ejecting operation command is issued to the automatic ejecting device (not shown), such as opening the ejectors 5i119a to 19d, and the buzzer 23 sounds to notify the end of the kneading process.

When the take-out door 19 opens, the take-out limit switch 41 operates in conjunction with this, which initializes the current value of each control element to the initial value indicated by the pattern. Immediately, the machine enters a standby state so that the medium rolling process can be started 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 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, if we initially started with the pattern shown in Figure 6 for the first massage chamber, but as a result of sampling on the way, we determined that the "softness" would be a little hard if we left it as is. From now on, all you have to do is change the control elements so that the softness becomes a little softer, so press 34a6 of the finishing quality level selection buttons 34a. Then, from then on, the control elements change according to the pattern shown in FIG. For example, if the medium kneading time is set to 30 minutes and the quality level selection button 34a6 is pressed 8 minutes after the start of the medium kneading, the pattern shown in Fig. 6 written in the working area of the first kneading room The unexecuted portion, that is, after the 9th step, is rewritten to the pattern after the 9th step of the pattern shown in FIG.

In this state, the process was proceeding, but when sampling was performed again, it was determined that the "tea temperature" was likely to become slightly abrasive. In that case, press 35as of the tea temperature level selection buttons 35a. Thereafter, the control elements are changed according to the pattern shown in FIG. For example, if the level selection button 35a is pressed 20 minutes after the start of the middle massage, the unexecuted portion of the pattern written in the working area of the first massage room, that is, the 22nd step onward, is the pattern shown in FIG. It is rewritten as 22nd step onwards.

(b) Thereafter, if there is no need to change, the pattern shown in FIG. 8 will be used to perform the middle kneading process up to 32 steps.

In the above example, as a result, the control elements in the first massage room are transitioned using the pattern shown in FIG. 9, and the working area of the first massage room is also A pattern as shown in FIG. 9 has been written. If good results are obtained by performing medium rolling while reselecting the finish quality level during the process, it is necessary to ensure that the original leaf quality of the tea leaves introduced into the medium rolling process is the same. As long as the control elements in the first rolling step are changed according to the pattern, similarly good results should be obtained. Therefore, when the tea leaves in the same state as the tea leaves introduced in the medium rolling process are subsequently subjected to medium rolling in the rolling chamber and other rolling chambers, the pattern may be used as a master.

(3) In the above example, the pattern written in the working area of the first massage room (the pattern as shown in FIG. 9) is used as a master to perform medium kneading in other massage rooms as well.

(a) Set the control method selection switch 26 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 transition of the hot air temperature equal volume control element in all the massage chambers is 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 40a.

(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 medium rolling process is started.

(d) If the input command switches 40b to 40d are pressed for the massaging chambers other than the master massaging chamber, tea leaves will be supplied starting from the one whose current value of the control element has reached the initial value set in the master pattern. Then, the middle massage begins.

(e) Then, the control elements are changed according to the master pattern for each rolling chamber, and when the middle 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 intermediate kneading process is being carried out while 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 5a of the first medium rolling machine is used as the master, the finishing quality level selection button is operated while sampling the rolling chamber 5a of the first medium rolling machine, and as a result, as shown in FIG. Assuming that the control elements are changed according to a pattern, the kneading chambers 5b to 5d of the other medium kneading machines
Also, the control elements are changed in accordance with the pattern of the master massage chamber 5a.

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, so that data can be saved even if the power switch 22 is turned off.

Therefore, for example, if the result of the transition of each control element in the kneading chamber 5a of the first medium kneading machine is good and it is a pattern that you would like to continue to use, for example, set the control method selection switch 26 to the first master and save the pattern. Press the recording area designation button, e.g. 25a, corresponding to the number of the recording area to be saved, and turn the record/call switch 28 to the "record" side.This operation will display the pattern in the working area for the massaging chamber 5a of the first medium massaging machine. is the memory RAM recording area No.
, 1! 3 and the buzzer 23 will sound when the transfer is complete.
sounds. The patterns of the other massaging chambers 5b to 5d can be saved in the same way.

When trying to change the volume control elements such as the hot air temperature in the massaging chamber 5b of the second medium massaging machine using such a pattern stored in the recording area as an index, the pattern to be used as the index is Press the recording area designation button, for example 25a, that corresponds to the number of the saved recording area,
Also, set the control method selection switch 26 to "2nd" indicating the massage room to be changed according to the pattern, and turn the record call switch 28 to the "call" side. As a result, the pattern in the recording area is transferred to the working area of the selected massage room 5b, and when the pattern is completed, the buzzer 23 sounds. Then, when the medium kneading process of the kneading chamber 5b is started, each control element of the kneading chamber 5b changes using the pattern as an index.

Moreover, it is of course possible to use the pattern called out from the recording area in this way as a master pattern. For example, in the above example, if the pattern stored in the second recording area (specified by button 25b) is to be called up to the working area corresponding to the rubbing chamber 5b of the second medium kneading machine and used as the master, the control Method selection switch 2
If the position No. 6 is left unchanged as the "second" of the "master" and the input command switches 40a to 40d are pressed for each kneading chamber, the middle 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 medium rolling machine, but it is also possible to use one medium rolling 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, all those that affect the finished quality of tea leaves during the rolling process.
