Description

DETAILED DESCRIPTION OF THE INVENTION [Field of industrial orchid industry] The present invention is based on the drying of seaweed in a seaweed dryer. For more details, please refer to the drying method for drying seaweed. At the end of the seaweed drying process, a seaweed cage containing raw seaweed is supplied to the seaweed dryer.
The present invention relates to an apparatus and method for automatically stopping a foreign book burner after a predetermined period of time has elapsed.

"Prior Art" Conventional seaweed drying equipment and drying equipment have been devised at manufacturing sites, and various documents based on these have been published. On the other hand, based on the above device < 4
A large number of inventions and ideas have been proposed, and the problems they are trying to solve are also wide-ranging.

Among them, raw seaweed is supplied to a seaweed cage that circulates from the start of the I# moss dryer, which is the object of the present invention, to the seaweed dryer and the paper shaving machine, and the seaweed cage provided with this raw seaweed is In the case of preventing filtration drying in the process of starting papermaking (hereinafter simply referred to as the required starting time), which takes about 1 hour for fi + to reach a predetermined position of the seaweed dryer. Or, the supply of raw seaweed to the seaweed cage circulating in the seaweed dryer is stopped, and the number of sheets of seaweed in the seaweed cage in the seaweed dryer is reduced (hereinafter simply referred to as the required time before stopping). ) Conventionally, in the method of trying to prevent filtration drying, an operator visually inspects the seaweed from the side window of the seaweed dryer, or inserts his or her hand and feels the drying state or position of the raw seaweed. The primitive method of controlling temperature by relying on so-called experience and intuition, which involves checking the temperature and starting or stopping the operation of the burner, is generally practiced.

On the other hand, in technical literature, etc., as a moss dryer for boat fishing, a method and device for automatically controlling the temperature and humidity in this process is described as a series of processes from supplying fresh and FI moss to stopping the supply. Although there are many documents, there are very few inventions and methods for automatically turning on and off the burner at the required start time or required time before stopping of the above-mentioned seaweed dryer, which is the object of the present invention. , inventions related to these two are strongly desired.

``Problems that inventions cannot solve'' As detailed above, experience or! The method that relies on 11 requires a lot of experience, and it is necessary to visually check the supply status of raw seaweed at the required startup time, or the supply stop status of raw seaweed at the time before the required stoppage, as described above. In addition, it is necessary to turn on and off the burner by touching it with your hand, and during this time the nori dryer is occupied and you cannot do other work, making it difficult to set up the work, and it is inefficient. There were some problems with the fire, etc.

Z Based on conventional intuition and experience, when turning on and off the burner, it is possible to accurately grasp the circulation transition of the nori cage inside the nori drying tunnel.
It was not possible to clearly determine in what process the circulation transition process of the seaweed cage caused the temperature/humidity control failure, that is, the temperature/humidity control failure inside the seaweed drying +041, and the response was delayed due to the inability to take appropriate and prompt action. There is a risk that it will turn into Therefore, the temperature control is not necessarily uniform, and as a result, the consistency of the quality of the dried seaweed cannot be ensured, leading to the production of defective seaweed. .

"Means for Solving the 8th Amendment" In view of the above, the present invention provides the required starting time ζ for the seaweed dryer.
When drying seaweed in ovens, or how many hours it takes for the seaweed dryer to stop, in each process, we grasp the stages of circulation in the seaweed cages in which the seaweed is placed, and at this stage, we The gist of this is to manage the temperature and humidity of each seaweed dryer based on preset control conditions, and specifically, the device is equipped to circulate the seaweed to the seaweed dryer. a detector that detects the passage of the seaweed pen, a counter circuit that receives the signal from this detector, a comparator that receives the output signal from this counter circuit, and a command signal that is input to this comparator. and a command circuit that instructs each V4 seaweed device to start or stop operation through comparison with a setting signal already input to the comparator, preferably the command circuit and/or the counter. In order to visually display the output signal from the circuit, the counter circuit is configured with a display device connected via a display circuit, and is installed in a seaweed cage or the like in which raw seaweed is provided to the seaweed dryer. The passage transition is detected>H and the state of passage of the seaweed pen is displayed on the display. It is characterized by automatic control such as starting or stopping the operation of various devices such as humidifiers? U moss! 2.Drying inspection.

Furthermore, as a way to do that, what about using a seaweed dryer? In a seaweed drying method in which dry seaweed is produced by supplying 111N fresh seaweed to a seaweed tank set up so as to move around, the seaweed tank is Circulation movement within the seaweed dryer is detected through a detection port means, and the movement of the seaweed basin (corresponding to the movement of the seaweed basin) is automatically controlled to start operation or float up of equipment installed in the seaweed dryer. . A method for drying seaweed, characterized by preventing overdrying or cracking of seaweed during the required drying process.

etc.

``Function'' Next, to explain the present invention in detail, first, the counter circuit of the 7rB moss dryer is installed (the counter circuit of the 1ltj device; this frame is set, that is, the moss cage is circulated in the nori dryer). The frame is set to detect the number of passing sheets that can be placed at a predetermined position and output a command signal from the counter circuit based on this.Then, t!t Turn on the switch of the 1tri moss I2 dryer.
L. The seaweed cage is circulated and the seaweed is circulated; raw seaweed is sequentially supplied during the so-called starting time. With this, seaweed! 2. A detector installed inside the dryer detects the number of fresh seaweed passing through the seaweed cage, and inputs the detected number to a counter circuit. The data inputted in this counter time Ya-2 is transmitted through the display circuit connected to it, and its F11 time is displayed on the frame movement display lamp of the display, and the data is displayed at the tip of the seaweed cage where so-called raw seaweed is placed. The position is sequentially displayed on the moving frame display, and the lamp located behind the moving frame is always lit. In addition, the moving frame display can also be done by directly displaying the number of sheets of seaweed in the seaweed basin of the seaweed dryer. It is also possible to capture it in detail (looking down).

In this way, when the counter circuit detects the set number of sheets and enters the so-called required start time, its output signal is input to the comparator, and the set number of sheets or set percentage (hereinafter simply The set number of sheets is compared with the input detected number of sheets, and if the two numbers match, the amount of raw moss in the iFi moss dryer is compared. The seaweed cage in which the seaweed is installed is about 1l4, and a command signal is issued to the command circuit connected to the counter circuit, and based on this command signal, the seaweed dryer is equipped. For example, the front burner enters, and the outside air introduced into this heating chamber is warmed through heat exchange with the pot.
Hot air is generated here.

In this way, the supply of hot air into the seaweed dryer is
If the seaweed is supplied a little later than the raw seaweed, the humidity inside the seaweed dryer will be replenished by the humidity that evaporates from the raw seaweed in the seaweed dryer.
ii) Over-drying of the moss is avoided. This also allows resources such as heavy oil and gas required for the operation of the burner to be saved.

Then, there is l1l of raw seaweed in the ii moss cage (i
At the same time, the detector detects the number of sheets that have passed after that, and when this counter circuit detects the set number of sheets, the comparator → command circuit → the rear burner turns on →
Following the process of generating hot air and supplying hot air to a 1m moss dryer,
Drying of seaweed (within 1 hour, hot air is supplied, and about 1/4 to 1/2 of the fresh seaweed is fed into the seaweed cage in the seaweed dryer, and the above-mentioned required starting time ends at this point, and the hot air is The supply amount is almost equal to the total supply amount of the seaweed dryer, and from then on, this supply is maintained until the required startup time as a general rule, resulting in the so-called regular operating condition.4 In the above manner, the regular A situation has arisen in which the seaweed cage containing raw seaweed reaches the specified position of the seaweed dryer, and a detector detects the situation in which sufficient hot air and raw seaweed are supplied to the seaweed dryer. When the number of sheets F1 is detected based on the number of sheets F1 passing through the moss cage each time, the number of sheets detected is input to the comparator as an output signal from the counter circuit.

This input number of sheets is compared with the set number of sheets inputted in advance to this comparator, and the set number of sheets and the input number of sheets are compared.
Compare the number of sheets and if the two numbers match, a command circuit connected to this; one command word is issued, and based on this command signal, the seaweed peeling machine connected to the seaweed dryer is activated. Due to the preparations for peeling and collecting the dried seaweed, the dry seaweed production operation is in progress.

In this way, the supply of raw seaweed to the nori cage circulating in the seaweed dryer is repeated 1lli times, and all the frame movement displays on the display are lit, and raw seaweed is supplied to the nori cage circulating in the nori dryer. As far as possible, the frame movement display should be permanently lit.

When the production of dried seaweed is finished, the so-called required pre-shutdown time has elapsed, and when the paper machine stops operating and the supply of fresh seaweed to the seaweed cage is stopped, the dry seaweed installed in the Jm moss dryer is A detector detects the number of sheets of seaweed passing through a seaweed tank with no raw seaweed, and inputs the detected number of sheets to a counter circuit.

The data input to this counter circuit is transmitted through the display circuit connected to it, and the number 1 is displayed in the frame movement display column of the display, and the tip of the so-called moss cage without fresh seaweed is placed. Display this on the frame movement display in the form of 111m turn-off, and inform the operator of the progress status of the seaweed cage without raw seaweed by stirring once through the frame movement display.

In this way, the required pre-shutdown time is reached, and specifically, the seaweed tank with raw seaweed in the seaweed dryer is approximately 1/2 full.
When it reaches about 1/4, the detection signal is input to the comparator via the counter ¥3, and is compared with the set number of sheets inputted in advance to this comparator, and the set number of sheets and the input detected number of sheets are compared. If the number of sheets matches, etc., a command word is issued to the command circuit connected to this, and based on this command signal, the seaweed dryer is equipped. Turn off the burner for posterity. This eliminates wasteful combustion in the burner and helps conserve resources. Approximately half of the total amount of hot air supplied into the moss dryer is supplied from the front heating chamber.

Then, when the number of seaweed ponds containing raw seaweed that is being circulated further decreases, the detector simultaneously detects the number of sheets that have passed through, and when this counter circuit detects the set number of sheets, the comparator → command circuit The process is as follows: turning off the side burner → stopping airflow generation → stopping the supply of hot air to the nori dryer, and then the supply of hot air to the inside of the nori dryer is stopped.

``Embodiment'' Below, an embodiment of the present invention will be described in detail based on the drawings. 1 is a normal seaweed dryer, and this seaweed dryer is connected to a heating chamber 2 on the front side through a communication port 1a etc. A heating chamber 2a on the rear side is connected to the rear heating chamber 2a. Then, the front and rear heating chambers 2.
2a: Koha burner 3.3a and suction fan 4.4a
are provided for each.

5 in the figure is a surface moss cage that circulates within the seaweed dryer l,
A part of this seaweed basin 5 reaches the paper making machine 6, and the paper making machine 5 and the seaweed drying 4+! through a drive device (not shown).
This is a circular transition within 1. 7 is a seaweed peeling machine.

In this example, the display 11 connected to the detector IO provided in the seaweed dryer 1 includes a frame movement display 12, other indicators such as burner on/off, fan on/off, peeling machine on/off, etc. A switch etc. are provided. The principle of the frame movement display 12 is the lighting display 13 indicating whether the light is on or off as described above, the frame numerical display 13a of the number of narrow frames, etc. ).

In addition, the heating chamber 2.2a, burner 3.3a, detector 1
0. The installation location and number of the display device 11 etc., the equipment display of the display device 11, etc. are only examples, and are not limited to this example.
Any member having the same effect is included within the scope of the present invention.

In the figure, reference numeral 20 denotes a frame setting section, and this frame setting section 20 sets a break for the desired number of frames in the counter circuit 21. The counter circuit 21 includes various devices such as a burner 3.
．． Comparators 22a to 22n are connected to the comparators 22a to 22n, which control the various devices such as burner 3.3a, fan 4.4a, humidifier, etc. (not shown). ) command circuits 24a to 2 that send commands to etc.
4n is connected. Further, various setting units 23a to 23n are connected to the comparators 22a to 22n, respectively. 25 is a display circuit interposed between the counter circuit 21 and the display 11.

Next, the method of the present invention will be described in detail with reference to FIGS. 5 to 7. First, a frame is set in the counter circuit 21 of the control device installed in the nori drying machine 1, that is, nori drying 4. f! l
The frame is set so that the number of sheets of seaweed that can be placed at a predetermined position in the seaweed cage 5 that circulates within the space is detected, and a command signal is output from the counter circuit 21 based on this.

the? &Turn the switch for the dried seaweed 1 to ONL/ to cause the seaweed cage to circulate, and raw seaweed is sequentially supplied to the circulating seaweed cage 5 during the so-called start-up time. Thereby, a detector 10 installed in the seaweed dryer 1 detects the number of sheets of fresh seaweed passing through the moss basin 5 provided therein, and inputs the detected number to the counter circuit 21. The data input to this counter circuit 21 is transmitted through a display circuit 25 connected thereto, and its numerical value is displayed in the frame movement display 12 column of the display 11, and the number is displayed in the nori basin 5 where so-called raw seaweed is placed. The position of the tip of the frame is sequentially lit up and displayed 13 on the frame movement display 12, and the lamp located at the rear of the moving frame is lit at all times. This process is in a dry state immediately after startup, as shown in Figure 7A, and in this state, burners 3 and 3 are still in use.
Since a is in the cut state, the temperature and humidity inside the seaweed dryer 1 is similar to the temperature and humidity inside the seaweed drying factory. On the other hand, in the conventional method, the operation of the burner is usually judged visually and the on-off is controlled, as shown in FIG. 6A, which is similar to the present invention.
Based on the temperature and humidity inside the Haboi # moss drying factory.

In this way, when the counter circuit 21 detects the set number of sheets and enters the so-called required start time, the output signal is input to the comparator 22a, and the output signal is input to the comparator 22a in advance via the burner setting section 23a. The set number of sheets is compared with the set number of sheets, and the set number of sheets is compared with the inputted detected number of sheets, and if the two numbers match, a command signal is issued to the command circuit 24a connected to this, and the seaweed is dried based on this command signal. A burner 3 installed in the machine 1, for example on the front side, enters the heating chamber 2, and the outside air is introduced into the heating chamber 2 and warmed through heat exchange with the kettle, thereby generating hot air. This hot air is supplied to the seaweed dryer v11, and is first supplied to the seaweed dryer 1 when the seaweed cage provided with fresh seaweed moves forward and reaches approximately 174 cm. In this way, if the supply of hot air into the seaweed dryer 1 is delayed somewhat compared to the supply of raw seaweed, the humidity inside the seaweed dryer 1 will increase due to the humidity that evaporates from the raw seaweed in the seaweed dryer 1. Since it is replenished, over-drying of raw seaweed is avoided even if hot air is continued to be supplied, and it is also useful for resource conservation.

Then, raw seaweed is sequentially supplied to the seaweed pen S, which circulates, and at the same time the detector 10 detects the number of seaweed that has passed since then.
Li, when this counter circuit 21 detects the set number of sheets, the same process as described above is followed: comparator 22b → command circuit 24b → rear burner 3a is turned on → hot air generation → hot air is supplied to the seaweed dryer 1, and ii. moss drying. Hot air is sequentially supplied into the machine, and there are approximately 174 sheets of raw seaweed in the seaweed cage 5 inside the seaweed dryer 1.
Approximately 1/2 of the amount of fuel is supplied, and the required starting time ends at this point, resulting in a normal operating condition.

In the start-up drying process with the above-mentioned required start-up time, in the conventional drying method, as shown in Figure 6, the supply of hot air from the heating chamber 2.2a is smooth, but the supply of raw seaweed is slow. Since it takes a certain amount of time for the drying capacity of the seaweed dryer 1 to reach the drying capacity of the seaweed dryer 1, the humidity decreases and the seaweed becomes overdried, which adversely affects the seaweed. However, in the present invention, as described above, the operation of turning on the burners 3 and 3a is performed by the method of self-control 1a11 using a large amount of moss. Therefore, as shown in Figure 7, the humidity decreases from the first shift in the moss drying box 1,
A desirable drying condition is achieved by changing the temperature rise by 1 x y per hour. In this case, the front and rear burners 3.
3. It is preferable to eliminate the IIIQ i missing control f.'L.

In addition, before the above-mentioned regular operation situation was reached, fresh seaweed was provided by Riko. Every time the moss tank reaches the designated device of the moss drying machine, ir! When the detector 10 detects that sufficient hot air and fresh seaweed are being supplied to the moss dryer l based on the number of sheets of seaweed 15 provided with "raw seaweed", the detected number is calculated by a counter circuit. 21 as an output signal to the comparator 22c.
It is compared with the set number of sheets inputted in advance in C via the humidifier automatic correction setting section 23c, and the set number is compared with the inputted number of sheets for inspection, and if the two numbers match, etc., it is connected to this. A command signal is issued to the command circuit 24r, and the command signal 22 is installed in the seaweed dryer 1 (for example, in the heating chamber 2.2a at the front 1j, 1I and/or rear ω). The suction fan 4.4a is activated, and outside air is actively introduced into the heating chamber, and the hot air generated by the heater is supplied to the moss dryer 1.

As described above, the normal operating condition is reached, and the moss cage 5 with fresh seaweed reaches the predetermined position of the seaweed dryer 1, and sufficient hot air and fresh seaweed are supplied to the seaweed dryer 1. When the detector 10 detects the situation where raw seaweed has passed through the seaweed basin 5, the detected number is sent to a comparator (not shown) as an output signal from the counter circuit 21. is input.

This input I2 number is compared with a set number of sheets that has been input in advance through this comparator ζ sawing machine setting section (not shown), and the set number of sheets is compared with the input detected number of sheets. If a match is found, a command signal is issued to the connected command line N4 (not shown), and based on this command signal, the seaweed peeling machine 7 connected to the seaweed dryer 1 is activated to remove the dried seaweed. By preparing for the peeling process, the production operation of dried seaweed becomes operational.Thus, in this example, automatic operation of 7 peelers and 6 food sources are achieved.

In this way, when the supply of raw seaweed from the surface moss tank 5 to the surface moss tank 5 which is circulated and transferred in the seaweed dryer 1 is completed, the frame movement displays 12 :, t of the display 11 are all lit up, and the seaweed transferred to the various T2 As long as the moss is supplied to the screen 5', the frame movement display 12! , is a regular format.

In this normal operation, as shown in Fig. 7 (c), the temperature, absolute humidity, and relative humidity change approximately at the set one shift. Note that in the normal process of step 3, the seaweed drying IQI may be in a high humidity state, so in such a state, the dehumidifying fan (not shown) is automatically controlled in the same manner as described above. This controls the increase in humidity, and also enables automatic control of the dehumidifying fan.

When finishing the dried seaweed manufacturing operation, the so-called required pre-stop time is 22 hours, and when the operation of the cutting pod 6 is stopped and the supply of raw seaweed to the seaweed pen 5 is stopped, the seaweed drying process is completed.
A detector 10 installed inside detects the number of sheets of seaweed passing through the seaweed cage 5 without any seaweed, and inputs the detected number to a counter circuit 21.The data input to this counter circuit 21 is Through the connected display circuit 25, the number is displayed in the column 12 of the frame movement display 12 of the display 11, and the light is sequentially turned off in the frame movement display 12 when placed at the tip of the seaweed basin 5 without so-called raw seaweed. The progress status of the seaweed cage 5 with no raw seaweed is visually communicated to the operator via the frame movement display 12.In this way, when the counter circuit 21 detects the set number of seaweed sheets, a so-called required stop is performed. When entering the previous time, the output signal is input to the comparator 22d, and compared with the set number of sheets inputted in advance to the comparator 22d via the burner cut setting section 23d, and the set number and the input detected number of sheets are compared. If the number of sheets matches, etc., a command signal is issued to the command circuit 24d connected to this, and based on this command signal, the burner 3a installed in the nori drying fit, for example, on the rear side is turned off, making it unnecessary. In addition to stopping the generation of hot air, it is useful for saving resources as described above.Therefore, approximately half of the total amount of hot air supplied to the seaweed dryer 1 is supplied from the heating chamber 2 on the front side.

Then, when the raw seaweed is sequentially stopped from being transferred to the seaweed pen 5, the detector 10 detects the number of sheets that have passed,
When this counter circuit 21 detects the set number of sheets, the comparator 22e (burner cut setting section 23e) → command circuit 24e → turns off the burner 3 in the previous example → stops hot air generation → hot air supply to the seaweed dryer l is started as described above. Following the process of being suspended, seaweed! The supply of hot air to the dryer 1 is sequentially stopped.

In the pre-stop drying process of the above-mentioned required pre-stop time, in the conventional drying method, as shown in FIG.
The raw seaweed supplied to the heating chamber 2.2a is stopped, and the number of seaweed cages 5 containing the seaweed in the seaweed dryer 1 gradually decreases, while the axial wind from the heating chamber 2.2a Since the supply is steady, the humidity drops and the seaweed becomes overly dry, giving the raw seaweed a tinge of Koisugi.

Therefore, in the past, the burner was turned off by inserting one's hand into the seaweed dryer and sensing the drying state of the raw seaweed by touch or visually checking. Therefore, this method has the disadvantage that the operator is restricted to this operation and cannot perform other tasks, resulting in inefficiency. However, as described above, in the present invention, the operation of the burners 3a, 3 is controlled by detecting the transition of passage through the seaweed basin 5 in which fresh seaweed is provided, so as shown in FIG. As shown in the figure, the decrease in humidity and the increase in temperature from the setting section in the seaweed dryer 1 can be replaced with time and can be controlled in a controlled manner. Therefore, seaweed! 2. Automation of the dryer 1 or other suitable drying conditions can be adopted. In this case, use the front and rear burners 3a and 3 as in this example! Automatic control without exception is preferred.

The H arrangement and method of the present invention are configured as in the example detailed above, but the basic concept is that t4i'flI device 1
Based on the detection of 0, the counter circuit 21 and the comparator 22a
The operation of the various devices installed here, such as the burner 3.3a and the peeling machine 7, etc. is started or stopped through the control circuit such as ~22n, etc., and as another example, the display 11 and the Although not shown in the figures, it is conceivable that the present invention may be used in collaboration with, and/or independently, to control the start and stop of a humidifier, etc., but these inventions are not included within the scope of the present invention. be.

``Effects of the Invention'' As described in detail above, the present invention has the advantage that the burner is automatically turned on at the beginning of the drying process and/or at the end of the drying process when fresh seaweed is put into the seaweed dryer. Then, the supply of raw seaweed to the seaweed dryer is stopped, and then the drying process is completed by turning off the burner at any point where the required time has elapsed, so the burner and the equipment for that pond are started and also:! It becomes possible to automatically control the automatic stop, and further automation of seaweed dryers is expected, and it becomes possible to save energy, save labor, and reduce costs. This eliminates the need to monitor and operate each burner as in the past, greatly contributing to the simplification and efficiency of work.

In addition, it is possible to eliminate defects caused by overdrying, such as tearing and shrinkage, and defective seaweed in which the center of the dried seaweed is raw and the surrounding area is shrunken. Furthermore, here is an example of the harmful effects of high humidity and dryness! 2. It is possible to eliminate defects such as uneven drying, drying, and poor gloss. ii. The occurrence of moss. In addition, automatic continuous drying operation becomes possible, which makes it possible to move away from the conventional seaweed drying method that relies on experience and intuition and requires skill, and enables the production of high-quality dried seaweed with constant quality. High-quality dried seaweed can be produced reliably and at a high rate.
