Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a new tea manufacturing method and tea manufacturing and roughing device, and more specifically, conventionally, a skilled person must always be near the machine and operate it according to the progress of the process. The temperature and volume of the hot air sent into the rolling and drying room, the rotation speed of the spindle on which the crusher and dredge are attached, the position of the spindle, etc., and the position of the spindle are important factors in each tea manufacturing process. The transition of elements,
First, the records of when a skilled engineer tried and was able to obtain a good product were used as indicators.
There is no need for skilled technicians to operate the rough-rubbing process, which is repeated continuously, and even if the rough-rubbing process is left to an unskilled person, it will still be the same as if it had been 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 good product and have uniform quality.

The tea manufacturing process is a process in which the tea leaves steamed in the previous process are gradually dried with hot air while being crushed or stirred in a drying chamber until the residual moisture content in the tea leaves reaches approximately 50%. It is important to keep the leaf temperature around 36 to 37 degrees Celsius and to dry the leaves as consistently as possible without over-drying. 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 drying chamber having a roughly cylindrical kneading body, and a kneading hand for pressing the tea leaves against the kneading barrel to apply pressure, and a kneading hand for stirring and stirring the tea leaves. The tea leaves that have undergone the previous process are placed in the drying chamber, and the main shaft is rotated to apply pressure and agitation to the tea leaves. It supplies hot air to gradually dry the tea leaves. Then, tea manufacturing elements such as the amount of tea leaves input into the rolling drying chamber, the temperature and amount of hot air supplied into the rolling drying chamber, the rotation speed of the spindle, the position of the leaf stopper, and the position of the spindle relative to the rolling barrel are controlled as appropriate. This will give you the best roughness.

However, in this tea processing process,
It is not possible to say unambiguously the temperature of each tea manufacturing element, such as the temperature of the hot air and how it should change as the process progresses. It is impossible to set and process 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 tea varieties, differences in production areas, differences in annual rainfall and sunshine hours, and differences in the day before the day of harvesting. Due to differences in various conditions such as differences in weather,
This is because the condition of the fresh leaves changes slightly, and furthermore, the condition of the steamed leaves introduced into this rough rolling process changes variously depending on the steaming treatment in the previous step.

Therefore, if we were to say that just because we had good results in the rough rolling process during the previous year or the previous harvesting process, we should change each tea manufacturing element in the same way in the rough rolling process this time, but that is not necessarily the case. Sometimes you get good results, and sometimes you don't. In addition, the tea making process is carried out in a battlefield-like atmosphere, and the opening degree of the airflow damper and the duration of the opening degree, which change at any time during the roughening process, can be recorded every time. not.

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

From this point of view, in the tea manufacturing and rough rolling process, a skilled technician called a tea master is always by the side of the rough rolling machine and monitors the progress of the rough rolling process. The reality is that each tea manufacturing element, such as the temperature of hot air, is controlled during the coarse rolling process, based on experience and intuition, with reference to texture, wetness, etc.

Furthermore, even if a skilled engineer is always nearby 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 subtle differences in the results each time. be.

The tea processing method and tea processing device of the present invention have been developed in consideration of these points, and the operation to obtain a user-created pattern that serves as an index for the transition of tea processing elements depends on the skills of a skilled technician. I will do it, but
In the subsequent repeated processes, these patterns are used as indicators to determine the transition of tea manufacturing elements, thereby creating a new tea manufacturing and roughing method that makes it possible to mass-produce tea of high quality and uniform quality. The purpose is to provide a kneading device.

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

FIG. 1 schematically shows a tea processing machine 1. As shown in FIG. 2 is a hot air generator attached to this tea processing machine 1. Reference numeral 3 denotes a frame of a tea processing machine, on which a rolling barrel 4 and a main shaft drive section 5 are mounted. The massaging body 4 has a gutter shape with both ends closed.

Reference numeral 13 denotes a steamed leaf pool placed at the upper exhaust port of the stirring chamber 10. Tea leaves are put into this pool until it reaches a predetermined weight, and the lower door 1
When the tea leaves 4 and 14 are opened as shown by the two-dot chain line in FIG. Note that this steamed leaf pool 13 is usually equipped with a tea leaf weight measuring device. Reference numeral 15 denotes a wire mesh that covers the upper end exhaust port of the stirring chamber 10. Reference numerals 16, 16, . . . are displacement adjustment dampers disposed inside the wire mesh 15 at the upper end of the agitation chamber 10, and the opening/closing degree of the dampers is adjusted by a damper adjustment motor 17 fixed to the frame 3. It's getting old. 18 is a hot air guide formed on the rear side of the stirring chamber 10, and a hot air generator 2 is connected at one end thereof.
The hot air outlet 19 is in communication with the hot air outlet 19 .

The hot air generator 2 includes a heat exchange section 20 and an air supply fan 21
It consists of The heat exchange unit 20 includes a furnace cylinder 23 and hot air passages 24, 2 connected to the furnace cylinder 23 in a casing 22.
4, . It passes through the chimney 26 and is discharged from the chimney 26. Incidentally, the burner 25 includes, for example,
Although not shown, two nozzles that generate different amounts of heat are provided, and the amount of heat can be determined by operating these two nozzles in three ways: igniting two nozzles, igniting one, and igniting the other. can be adjusted in three stages. Air is introduced from the outside directly or through a suitable filter by an air fan 21, enters the casing 22 through an air inlet 27 communicating between the air fan 21 and the casing 22, and enters the casing 22 through a hot air outlet. 19 into the wind guide 18. Then, when the air passes through the inside of the casing 22, the heated furnace tube 23
and the surfaces of the hot air passages 24, 24, . . . and are heated to become hot air. Then, this hot air is supplied into the drying chamber from the hot air blowing ports 12, 12, . . . through the hot air guide 18. 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 tea leaves is introduced into the tea leaf pool 13 that has completed the steaming process, and when the doors 14, 14 of the steamed leaf pool 13 are opened, the tea leaves are introduced into a rolling drying chamber consisting of a rolling barrel 4 and a stirring chamber 10. Ru. The hot air generated by the hot air generator 2 passes through the hot air guide 18 to the hot air inlet 12,1.
2, ... is supplied into the drying chamber. Then, the main shaft 7 is rotated, and the tea leaves are pressed and kneaded against the bottom of the kneading hands 8, 8, . . .
The liquid is stirred upward and dispersed by the water. Then, the tea leaves are rolled and agitated while coming into contact with hot air, and are gradually dried to proceed with the rough rolling process. The above operation is continued until the residual moisture 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 door 6 is opened, and the tea leaves are taken out onto the conveyor 29 below. , and sent to the next rolling 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 just 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 tea manufacturing element in the tea manufacturing process, such as the temperature of the hot air supplied to the rolling drying chamber, the amount of hot air, the rotation speed of the main shaft, and the position of the main shaft, must be adjusted in accordance with the progress of the process. Therefore, it is necessary to proceed sequentially. Therefore, the means by which these tea manufacturing elements are controlled in the tea making and roughing machine 1 will be explained by giving an example of those means.

First, the temperature of the hot air supplied to the drying chamber is controlled by adjusting the combustion degree of the burner 25. In this case, a temperature sensor is placed at an appropriate location on the hot air guide 18, and this detects the temperature of the hot air blown into the drying chamber. In other words, one of three modes may be selected: both of the two nozzles are ignited, only one of the nozzles is ignited, and only the other is ignited.

The amount of hot air supplied into the drying chamber depends on the number of revolutions of the air supply fan 21, the opening/closing degree of the exhaust volume adjustment dampers 16, 16, . It can be controlled by adjusting one or more of the opening/closing degrees of the damper disposed between the air port 27 and the damper.

The rotation speed of the main shaft 7 can be controlled, for example, by a mechanism shown in FIG. 30 is the main shaft drive unit 5
On this frame 30 is a reducer 3.
1 is fixed, and the output shaft (not shown) of this reducer 31 is connected to the main shaft 7 directly or via a universal joint or the like.
32 is a reducer pulley, which is connected to the input shaft 33 of the reducer 31.
is fixed. 34 is part 3 on frame 30
A main shaft drive motor 36 is fixed onto the speed change base 34, which is rotatably supported by the speed change base 5. A variable diameter pulley 38 is attached to the output shaft 37 of the main shaft drive motor 36, and a V belt 3 is connected between the variable diameter pulley 38 and the reduction gear pulley 32.
9 have been constructed. 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, the pulley 38 moves away from the other pulley 32. As it moves further away, the pressing force from the V-belt 39 acts on the two members forming the groove and widens the gap between them. As a result, the diameter of the groove in which the belt is placed has become smaller.
Further, when the speed change base 34 rotates in the direction of the dotted arrow, the two members forming the groove move closer to each other by the elastic pressure means, and as a result, the diameter of the groove becomes larger. 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 40.
is provided, and this sliding pin 42 is connected to an elongated sliding hole 4 provided at the free end of the speed base 34.
3 in a slidable manner. The free end of the transmission base 34 is constantly pulled in the direction of the arrow by a spring 44. An elongated sliding hole 45 is formed at the other swinging end of the speed change rod 40. 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. and,
A roller 50 is rotatably provided at the swinging end of the control rod 49, and this roller 50 is connected to the speed change rod 4.
It is slidably engaged with the sliding hole 45 of No. 0.

Therefore, the control rod 4 is controlled by the control motor 46.
9 is swung, 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 that direction.
Alternatively, 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.

Adjustment of the relative position of the main shaft 7 with respect to the kneading bottom can be accomplished, for example, by using a mechanism as shown in FIGS. 4 to 6. 51 is massaging body 4
This is a disk-shaped bearing disk that is rotatably supported by the frame 3 at both end positions of the frame 3. A bearing portion 52 for receiving an end of the main shaft 7 is formed at a position eccentric from the center of rotation of the bearing disk 51, and the end of the main shaft 7 is supported by the bearing portion 52. Reference numeral 53 designates a changing rod whose one end is fixed to the bearing disc 51, and the other end of which is formed with a long hole 54 extending in the longitudinal direction.
A control motor 55 is fixed to the frame 3, and a control rod 57 is fixed to its output shaft 56. A pin 58 is provided at the tip of the control rod 57, and this pin 58 connects to the aforementioned change rod 53.
It is slidably engaged with the elongated hole 54 of. It should be noted that the bearing disc 51, change rod 53 and control rod 57 as described above are provided not only on one side but also on the other side.

When the control rod 57 is rotated by the control motor 55 around the position of the output shaft 56 of the motor 55, the change rod 53, which is engaged with the tip thereof, rotates around the center of the bearing disk 51. Rotate as. Therefore, the bearing plate 51 which is in a fixed relationship with the change rod 53 is also rotated, and the position of the bearing portion 52 is changed to 2.
It is changed as shown by the dotted chain line. Therefore, the position of the main shaft 7 supported by the bearing portion 52 is changed. By changing the position of the main shaft 7 in this manner, the degree of kneading pressure on the tea leaves is changed. For example, when the main shaft 7 is at the position shown by the solid line in FIG.
When the position of becomes the position shown by the two-dot chain line in Fig. 4,
The kneading hands 8 will draw a trajectory shown by the two-dot chain line B, and the pressure applied to the tea leaves by the kneading hands 8 rotating in the direction shown by the arrow C will be increased compared to when drawing the trajectory A. That will happen. Therefore, by appropriately changing the position of the main shaft 7, the optimum degree of kneading pressure can be selected.

Reference numeral 59 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 59 has links 60 ₁ , 60 ₂ , 6
It is connected to a control motor 61 via a _0.03 mechanism, and is configured to rotate about a shaft 62 as shown by a two-dot chain line in FIG. Then, depending on the position of the leaf stopper plate 59, the dredges 9, 9, . . .
The trajectory of the tea leaves stirred up by the tea leaves changes. That is, the locus will be drawn as shown by the arrows I to D corresponding to the symbols I to D added to the reference numeral "59" of the leaf stopper plate in FIG. Then, as the trajectory changes from A to D, 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 below.
As shown in FIG. 8, for a tea processing and roughing device consisting of four machines 1a to 1d arranged, a so-called microprocessor is used to control the temperature, hot air volume, and main shaft 7 of the hot air supplied to the rolling and drying room. An example will be explained in which the method is implemented for the purpose of automatically controlling only the rotation speed and the spindle position. In addition, in FIG. 8, 63 is a processing machine;
4 is a vertical bucket, 65 is an inclined conveyor, 66 is a horizontal conveyor, and 67, 67 are input conveyors.

Also,

Using such a circuit, the hot air temperature, hot air volume, spindle rotation speed, and spindle position in the tea manufacturing and roughening process are controlled according to the flowchart shown in FIG.

(1) The user can individually set the value of each tea manufacturing element for each coarse rolling machine 1a to 1d using switches 83a to 83.
d, 84a-84d, 85a-85d and 86
When creating a pattern by operating a to 86d (a) Set the pattern selection switch 76 to "Individual creation"
(b) Roughing machine to be operated For example, roughing machine 1 in Figure 1.
Press the input command switch 82a, and input the tea leaves to be coarsely crushed. As shown in the flowchart in Figure 11, "What is the pattern selection?" is "Individual", so "Individual pattern is used for each rolling and drying room", and each tea manufacturing element of each roughing machine has a memory RAM. The circuit is configured so that the individual patterns stored in the working area corresponding to each roughing machine in the machine are used as indicators. In addition, when the user creates a pattern, in this embodiment, 1 address is prepared for each minute of rough rolling time, a total of 64 addresses, and the progress of the transition of each tea manufacturing element during the rough rolling process of up to 64 minutes can be memorized. That's what I do.

Then, suppose that the first part of the working area corresponding to the first roughing machine 1a of the memory RAM is
"Hot air temperature 95℃,
Assuming that a word indicating that the hot air volume is 150 m ² /min, the spindle rotation speed is 42 rpm, and the spindle position is 1 is written, the values of each of these tea manufacturing elements will be maintained at that value for 1 minute from the time of addition.
In the case of this embodiment, the pattern storage working area of the memory RAM is not initialized at the start of the roughing process, so each roughing machine 1a is actually
The working area corresponding to ~1d stores the trends of each tea manufacturing element such as the hot air temperature in the rough rolling process performed previously, and unless the switches are operated, these tea manufacturing elements will follow such a pattern. Therefore, there is a transition.

(c) Then, for example, after one minute has passed, the main shaft rotation speed setting switch 85 corresponding to the roughing machine 1a is turned on.
Operate a to change the spindle rotation speed from 42rpm to 43rpm.
If you raise it to .

In the flowchart of FIG. 11, the switch 8
An interrupt is generated by the operation in step 5a, and the question ``What is the pattern selection?'' becomes ``individual creation of a drying room'', and the word corresponding to the changed rotation speed of 43 rpm is assigned to the address corresponding to the elapsed time in the working area (e.g. It is recorded at the corresponding address from 1 minute to 2 minutes after the start.

In this embodiment, one and each setting switch 83a~
83d, 84a-84d, 85a-85d,
When 86a to 86d are pressed and the value of the corresponding tea manufacturing element changes, for example, when the rotation speed of the spindle 7 is changed after one minute has passed as described above, the value corresponds to the corresponding time in the working area of the memory RAM. Words corresponding to the rotational speed of 43 rpm are written from the address of The rotation speed is maintained at the rotation speed written in the memory, that is, 43 rpm.

(d) Thereafter, as the rough rolling process progresses, as the value of each tea manufacturing element is changed, the addresses after the address corresponding to the time of the change are rewritten each time.

(e) When the desired rolling pressure and shaping are applied, the user moves a predetermined ejection button (not shown) to open the ejection door 6 and take out the tea leaves, which is linked to the ejection door 6. The take-out limit switch 90a is closed. As a result, the time required from the start to the end of rough kneading, that is, the time of one rough kneading step, is stored in a predetermined address of the memory RAM, and in FIG. 11, "Is the rough kneading time over?" is set as "YES". Therefore, the hot air temperature, hot air volume, main shaft rotation speed, and main shaft position of the roughing machine 1a are returned to their initial values.

Through the above operations, the working area of the memory RAM corresponding to the rolling/drying room stores the transition of each tea manufacturing element such as the hot air temperature operated by the user during the first rough rolling process for that rolling/drying room as a user-created pattern.

Therefore, from the next rough rolling process onwards, each tea manufacturing element such as the hot air temperature can be changed using the user pattern as necessary.

In addition, the pattern selection switch can be created individually.
When placed in the position of
are stored as separate patterns in each working area.

(2) When performing rough rolling work using any of the rolling rooms, for example No. 1 rolling room as the master.

(a) Set the pattern selection switch 76 to "1st coarse"
Make it.

(b) Press the input command button 82a and input the tea leaves to be coarsely crushed into the rolling/drying chamber.

(c) As a result, in Figure 11, ``What is the pattern selection?'' becomes ``master op'', and the circuit is configured so that only the working area corresponding to the designated drying room is used, and all Changes in each tea manufacturing element such as the hot air temperature in the rolling and drying room are performed using the master rolling and drying room pattern as an index. Of course, when operating using a master pattern, the transition of each tea manufacturing element is performed individually from the beginning of the master pattern, even if the starting time is different for each kneading and drying room, just as with the ready-made patterns described above. .

Therefore, if you master the pattern of a rolling drying room that has already been tried and achieved good results, each tea manufacturing element in the other rolling drying rooms will move exactly the same as the one in the rolling drying room that has yielded good results. will be done.

(d) In addition, such an operation using a master pattern can be performed in the rolling drying room where an expert is currently nearby and is proceeding with the rough rolling process while adjusting each tea manufacturing element such as hot air temperature. This can also be done by changing each tea manufacturing element in the rolling and drying room.

That is, for example, when the drying chamber of the first roughing machine 1a is used as the master, the main shaft rotation speed setting switch 8 is set for the drying chamber of the first roughing machine 1a.
5a is operated, the rotational speed of the main shaft of the drying chamber of the first roughing machine changes accordingly, and the switch 85a changes as shown in FIG.
An interrupt operation is performed by the operation of
``What is the pattern selection?'' ``Master OP'' Therefore, using the same procedure as in the case of individual creation, select the address corresponding to the relevant operation point in the working area corresponding to the drying room of the first roughing machine 1a, which is the master. A word corresponding to the changed spindle rotation speed is written to all subsequent unexecuted portions.

(f) Thereafter, whenever the number of revolutions changes, a word corresponding to the new number of revolutions is written in the address after the address corresponding to that point in the working area corresponding to the drying room of the first roughing machine 1a. .

(g) When the rough rolling process is completed, if the tea leaves are taken out in the same way as when making individual tea leaves, the elapsed time from the start is stored in a predetermined area of the memory RAM, and the initialization, that is, An operation is performed in which the value of each tea manufacturing element is returned to its initial value.

(h) In this case, if you start rough rolling by pressing the input command switches 82b to 82d in order from the tea leaves that are ready to be input into the rolling rooms other than the master rolling room, for example, 1 minute after the main shaft of the chamber starts rotating
43rpm, and if it becomes 45rpm after 2 minutes, then the main shaft rotation speed of the kneading and drying chamber of the second rough kneading machine 1b will also change to 43rpm and 2. After a minute has passed
45 rpm, etc., using the master user-created pattern for the drying room as an indicator.

(3) When rough rolling was initially started using the existing pattern as an indicator, but the progress was not as desired.

(a) In this case, set the pattern selection switch to ``Individual Creation'' or ``Master 1st Rough
4. Roughly knead.

(b) As a result, after the switching point, each setting switch 83a to 83d, 84a to 84d, 85
The values of the tea making elements can be adjusted by operating the setting switches a to 85d, 86a to 86d, or the master rolling and drying chamber. In this case, the existing pattern transferred from the memory ROM remains as it is at the address before the address corresponding to the switching point of the working area corresponding to each drying room, and the address after the address The transition of tea manufacturing elements operated by the user is recorded, and this can also be used as a new user-created pattern.

The operations for each pattern have been explained 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 72 is turned off.

Therefore, for example, if the results of the transition of each tea manufacturing element in the rolling and drying chamber of the second roughing machine 1b are good and it is a pattern that you would like to continue using, for example, set the pattern selection switch 76 to the second roughing of the master, and switch to the store area. Set the designation knob 75 to position 1 and turn the load store switch 78 to the "record" side. By this operation, the pattern in the working area for the kneading and drying chamber of the second rough kneading machine 1b is transferred to the store area No. 1 of the memory RAM, and the buzzer 73 sounds when the transfer is completed. Other drying room patterns can be saved in the same way.

Then, using the pattern stored in such a store area as an index, for example, the first roughing machine 1a
When attempting to change the temperature of each tea manufacturing element such as the temperature of hot air in the drying room, set the store area designation knob 75 to the number of the store area where the pattern to be used as the index is stored, and also Set the pattern selection switch 76 to the drying chamber in which you want to change the pattern, and turn the load store switch 78 to the "call" side. As a result, the pattern in the store area is transferred to the working area of the selected drying room, and when the process is completed, the buzzer 73 sounds. Then, when the rough rolling process in the rolling/drying room is started, each tea manufacturing element in the rolling/drying room undergoes a transition using the pattern as an index.

As explained above, in the tea processing method and tea processing apparatus of the present invention, the user tries the transition of the tea processing elements in the first roughening step and uses the pattern in which a good result is obtained as an index. Therefore, there is no need for a skilled technician to be nearby while the rough rolling process is repeated, unlike in conventional rough rolling methods or devices. Anyone can carry out the tea processing work without renting a machine. Furthermore, since it is possible to faithfully and easily reproduce the transition of various tea manufacturing elements for processes that have obtained good results, it is possible to maintain the sameness of product quality, which was previously thought to be difficult to achieve even by experienced workers. can be easily realized. Furthermore, since several user patterns can be saved, it is possible to select a pattern suitable for the properties of the tea and carry out the tea processing operation. Furthermore, unlike the experience and intuition of experts, there is no risk of going wrong with these patterns, so any of these patterns can be used as a measure, and from the results, the properties of the tea can be determined. It is also possible to select a pattern suitable for the properties.

In addition, in the above explanation, each of the four rolling drying chambers is explained as one for each independent rough rolling machine, but even if one rough rolling machine equipped with multiple rolling drying chambers is used, Of course, there is no problem.

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

Furthermore, in the above embodiment, the operating units for setting each tea manufacturing element for the four rolling and drying chambers are placed together on the control panel, but this is arranged near each rolling and drying chamber. You may also do this.
