Abstract

PURPOSE:To obtain green tea having uniform and high qualities, by controlling the controllable elements in the rough rolling of tea leaves with a micro-computer according to the preset pattern stored in the memory. CONSTITUTION:A plurarity of patterns of the change of each controllable element in the rough rolling of tea leaves are prepared according to the properties of the tea leaves, based on the skill of the skilled technician or the results of experiments, and inputted to the memory of a micro-computer. The whole process of the rough rolling from the initiation to the end is divided into various unit steps, and the target level of the controllable element such as flow of hot air, etc. is set by the pattern for each unit step. When a specific pattern, e.g. pattern (a) is selected within the plural patterns according to the properties of the tea leaves, and the time for the rough rolling (44min) is set by the operator, the treatment of each step is carried out within the time (1.52min) calculated by dividing the rough rolling time with the number of total steps (29) to complete the rough rolling process.

Description

[Detailed Description of the Invention] 0 In detail, in the past, it was believed that a good product could not be obtained unless a skilled person was always near the machine and operated it according to the progress of the process. Patterns are created based on the results of repeated trials of the transition of each control element in the tea manufacturing process, such as the amount of hot air sent into the room, the rotation speed of the spindle on which the kneading hands and deep handles are attached, and the position of the main spindle. By making it possible to obtain a product of a certain level of quality or higher regardless of the skill level of the worker by using the pattern as an index during the rough rolling process, it is possible to obtain a product of a certain level of quality or higher. The rough rolling process is divided into several processes including the first beating process, and the time for the beating process is set by the user as desired, and the beating time specified in the pattern is If a different leaf beating time is set, the pattern will be transformed accordingly, and the selection of the pattern will make the transition of the control elements almost error-free.At the same time, the arbitrary setting of the leaf beating time will allow infinite It is an object of the present invention to provide a novel tea manufacturing and roughing method and a tea manufacturing and roughing device that are capable of setting phase conditions suitable for tea leaves having variations.

In the tea manufacturing and rough rolling process, the tea leaves steamed in the previous process are gradually dried with hot air while being crushed or indexed in a rolling drying chamber until the residual moisture content in tea confectionery reaches approximately 5θ%. During the process, it is important to dry the leaves as carefully as possible, without over-drying them, while keeping the leaf temperature almost constant. This will lead to deterioration in quality such as the generation of odor or stuffy aroma. Such tea manufacturing and rough rolling process is generally carried out as follows. A main shaft is arranged rotatably in the drying chamber, and a kneading hand for pressing and kneading the tea confectionery against the kneading barrel and a deep hand for scooping up the tea confectionery for sorting are attached to the main shaft. The tea S-leaves that have completed the previous process are put into such a rolling and drying chamber, and the main shaft is rotated to apply pressure and seeding to the tea confectionery, and hot air is supplied into the kneading and drying chamber to gradually make the tea confectionery. It is to be dried. Then, control elements such as the amount of tea confections input into the rolling drying chamber, the temperature and amount of hot air supplied into the rolling drying chamber, the rotation speed of the main shaft, the position of the leaf stopper, and the position of the main shaft with respect to the rolling drum are controlled as appropriate. By doing this, the best roughness is achieved.

However, in such a tea manufacturing process, it is difficult to say in general terms what temperature each control element, such as hot air temperature, should be at and how it should change as the process progresses. First, it is impossible to set a certain standard and process it uniformly. This is because tea is 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 area, yearly rainfall, differences in sunshine hours, and the day before harvesting. The condition of fresh leaves changes slightly due to various conditions such as differences in weather, and furthermore, the condition of steamed leaves introduced into this rough rolling process varies depending on the steaming treatment in the previous step. This is because things change.

Therefore, it is not necessarily the case that just because good results were obtained in the rough-rubbing process during the previous year or the previous harvesting, it is better to change the control elements in the same way in the rough-rubbing process this time. Sometimes the results are good, sometimes not.In addition, the tea making process is carried out in a battlefield-like environment, and changes can be made at any time during the roughening process, such as opening the airflow damper. It is not possible to record the degree of opening, the duration of the opening, etc.

This point also applies to changes in other control 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 near the rough rolling machine and monitors the progress of the rough rolling process. The reality is that various control elements, such as changes in the amount of hot air, are controlled during the rough kneading process based on experience and intuition based on the feel, wetness, etc.

Mabuko, even if a skilled engineer is always nearby to control the amount of hot air, etc., it is impossible to make the changes exactly the same, and it is undeniable that there will be subtle differences in the results every seven times. It is something.

The tea processing method and tea processing apparatus of the present invention have been developed in consideration of these points, and the work to create ready-made patterns that serve as indicators of control element transitions requires the skills of skilled engineers or experiments. This is done depending on trial and trial data, but
In the subsequent repeated processes, the transition of control elements is carried out using these patterns as indicators, thereby creating a new tea processing method and tea processing method that makes it possible to mass-produce tea of high quality and uniform quality. The purpose is to provide a kneading device.

Also, even if you prepare ready-made patterns, the characteristics of tea confections are ever-changing, so it is impossible to prepare all ready-made patterns that can be adapted to each one.
Even if one could prepare one, it would be difficult to select the most appropriate pattern. Therefore, we made it possible to freely set the time for the leaf beating process, which needs to be changed depending on the properties of the tea introduced into the rough rolling machine, especially the depth of steaming, and the time for this leaf beating process was selected. It is an object of the present invention to provide a novel tea manufacturing method and a tea manufacturing rough rolling apparatus in which the pattern itself is appropriately changed when the time differs from the leaf beating process time in the pattern.

In this way, by selecting a ready-made pattern that matches the properties of the tea confectionery and changing the control elements according to that pattern, any operator can perform rough kneading without making any major mistakes. By being able to arbitrarily set the beating time, it becomes possible to adapt to a variety of slightly different tea confections.

Into this, tea confectionery is placed until it reaches a predetermined weight, and the lower door /da, /ll is marked as shown in Figure 2. When opened as shown by the chain line, the tea leaves in the pool/3 are thrown into the rolling and drying chamber which consists of a rolling barrel and a seed chamber/θ. A device is attached to measure the weight of tea and sweets. /S is a wire mesh that covers the upper end exhaust port of the genus chamber 10. 0/6, /6,... The top of the genus chamber /θ -/O- is inside the wire mesh 15 at the end. A damper adjustment motor 17 fixed to the frame 3 with a displacement adjustment damper distributed Wt.
The degree of opening and closing is adjusted by 7
A hot air guide is formed on the rear side of the seed chamber lOO, and one end thereof communicates with the hot air outlet /q of the hot air generator.

The hot air generator consists of a heat exchange part -〇 and an air blowing fan 2/. The heat exchange part λθ includes a furnace cylinder 3 and a hot air passage 217.1.2 connected to the furnace cylinder 3 inside the casing.
A burner 2S is attached to the furnace cylinder 23, and the burner 23 generates fc hot air inside the furnace cylinder and 23 through a hot air path arranged in a labyrinth inside the casing. Chimney, 26 exhausts 0 Shang, burner, 2! ;IF, , for example, is not shown or is provided with one nozzle with a different heat generation, and one of these nozzles is ignited, one is ignited, the other is ignited, and so on. By operating in this mode, the amount of heat can be increased
Air, which can be adjusted in stages, is introduced from the outside directly or through a suitable filter by an air supply 7/2/, communicating between the air supply fan 2/ and the casing J, 2. Air enters the casing 22 from the air supply 0.27 and is supplied into the air guide 7g from the hot air outlet /q. Then, when the air passes through the inside of the casing 2.2, it passes through the heated furnace tube 23, the hot air path, and the casing 2.2.

Although not shown, a damper for adjusting the amount of hot air whose opening/closing degree is controlled by a control motor Ωg is arranged between the antenna 2/ and the air supply port 27.

1. The rough kneading process using the above-mentioned rough kneader is carried out as follows. A predetermined amount of tea leaves that have completed the steaming process are introduced into the steamed leaf pool/3, which is then transferred to the steamed leaf pool/? When the doors /'I and /'I are opened, the material is thrown into a drying chamber consisting of a massaging body and a mass chamber 10. The hot air generated by the hot air mechanism is supplied to the rub -dry room from the hot air derivation / G, and the hot air blowing mouth / 2, / ko, ... Then, the main shaft 7 is rotated and the tea leaves are rubbed by hand g.
It is pressed and kneaded on the kneading sole by g...
The water is scraped upward by the depth 9, wa,... to increase the number of tanks. Then, the tea confectionery is rolled and placed in several vats, brought into contact with hot air, and gradually dried to proceed through the Japanese style process. The above operation is continued until the residual water content of the tea confectionery reaches a predetermined value, and when the target value is reached, the roughening process is completed, the removal door 6 is opened, and the tea confectionery is taken out onto the conveyor 29 below. , and sent to the next rolling process.

As mentioned earlier, the tea making and rough rolling process described above has the significance of drying the tea cakes steamed in the previous process until the residual moisture content is about 3.0%; It is not sufficient to reduce the residual moisture to approximately SO%, but it must be done in such a way that the quality of the tea confectionery, such as its color and aroma, is not deteriorated. In order to do this, each control element in the tea manufacturing process, such as the temperature of 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 according to the progress of the process. If necessary, the means by which these control elements are controlled in the tea processing and rolling machine 1 will be explained by giving an example of such means.

First, the temperature of the hot air supplied to the drying room is determined by adjusting the combustion degree of burner 2.
By this, the temperature of the hot air blown into the drying chamber is detected, and the burn-up degree of the burner is adjusted based on the difference between this value and the target value at that time.In other words, both λ nozzles are ignited, only one is ignited You only need to select one of the three modes of ignition for the other side. The amount of hot air supplied into the drying chamber is determined by the number of revolutions of the air fan /, the exhaust volume adjustment damper /B, /B at the top of the drying chamber. ,・
It can be controlled by adjusting the opening/closing degree of ... and the opening/closing degree of the damper disposed between the air supply fan 2/ and the air supply port 27 of the heat exchange section 20.

The rotation speed of the main shaft is determined by the mechanism shown in Fig. 3, for example.
- A frame of an o30 main shaft drive unit S that can be controlled by a 30-degree shaft, on which a reducer 31 is fixed; and an output shaft of this reducer 3/ (not shown).
O3 is connected to the main shaft 7 directly or via a universal joint, and is a reducer pulley.
It is fixed to the input shaft 33 of /. 3q is frame 30
A variable diameter pulley 3g is attached to the output shaft of the main shaft drive motor 3B, on which the main shaft drive motor 36 is fixed on the transmission base J4', which is rotatably supported by the part 3S. A V-belt 39 is installed between the variable diameter pulley 3g and the reduction gear pulley 32. A groove for hanging the belt on this variable diameter pulley 3g is formed by a member joined by a pressure means, and the speed change base 3da rotates in the direction of the solid line arrow, and the variable diameter pulley 3g is rotated in the direction of the solid arrow.
When the pulley 3.2 moves away from the other pulley 3.2, the pressing force of the belt Jq acts between the members forming the grooves and widens the gap between them. As a result, the diameter of the groove in which the belt is hung becomes smaller. Also, when the transmission base 3'l rotates in the direction of the dashed arrow, the members forming the grooves approach each other by the pressure means, and as a result, the diameter of the groove increases. This is a speed change rod rotatably supported by the frame 30 at a portion q/. A sliding pin q2 is provided at one swing end of the speed change rod dog θ, and this sliding pin q2 can freely slide into an elongated sliding hole q3 provided at the free end of the speed change base 3da. Note that the free end of the transmission base ALL is always pulled in the direction of the line arrow by a spring +<2. 0II6 is the frame 3 in which an elongated sliding hole llS is formed at the other swinging end of the speed change rod θ.
The control rod 4/9 is oscillated by a control motor fixed on the rotor 0 via a rotation transmission system +7S speed reducer dag. A roller SO is rotatably provided at the swinging end of the control rod lIq, and this roller 30 is slidably engaged in a sliding hole qs of the speed change rod lIO.

However, the control rod '7? When the speed change rod θ is swung, the speed change rod θ is also swung, and as a result, the speed change base 3 is swung. Depending on the direction, the groove diameter of the variable diameter pulley 3g is increased or decreased, and the pulley 3.2, the rotational speed applied to the input shaft 33 of the reducer 3/ is changed, and therefore the rotational 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. 9 to 6. S/ is a disc-shaped bearing disc rotatably supported by the frame 3 at positions M at both ends of the kneading drum q. At a position eccentric from the center of rotation of the bearing plate S/, a bearing part octopus is formed to receive the end of the main shaft 7.The end of the main shaft is supported by this bearing part S. O53 has one end bearing a bearing. It is a change rod fixed to the panel 57, and a long hole sti along the longitudinal direction is formed at the other end. 〇5& is a control motor fixed to the frame 3, and the control rod S7 is attached to the output shaft 5O. A pin Sg is provided at the tip of the fixed 0 control rod 57, and this pin Sg is slidably engaged with the elongated hole 59 of the aforementioned change rod 53-/7-. Bearing plate &/or change rod S3 and control rod S as described above
It is provided not only on one side but also on the other side.

When the control rod S7 is rotated by the control motor S5 around the position of the output shaft 5A of the motor 55, the change rod S3, which is engaged with the tip of the control rod S7, is rotated by the control rod S7.
Rotates around the center of /. Therefore, change rod S3
The bearing plate S/ which is in a fixed relationship with is also rotated, and its bearing part S
The position of is changed as shown by the two-dot chain line. Depending on...
The position of the main shaft 7 supported by the bearing part 52 is changed. By changing the position of the spindle 7 in this way, the degree of kneading pressure on the tea leaves is changed. For example, when the spindle 7 is at the position shown by the solid line in FIG. 7, the kneading hand g follows the trajectory shown by the dotted line A. However, when the position of the main shaft 7 reaches the position shown by the dot-dashed line in Fig. 7, the kneading hands will draw the locus shown by the dot-dashed line B, and the kneading hands will be rotated in the direction shown by the arrow O. This results in an increase of 7 g compared to the case where the locus of the kneading pressure A on the tea leaves is drawn by g. Therefore, by appropriately changing the position of the main shaft 7, the optimum degree of kneading pressure can be selected.

The leaf stopper plate S9, which is a leaf stopper plate arranged longitudinally across the center of the upper part of the Sq seed number chamber/θ, has links Otsu01, Otsu02, Otsu0゜. It is connected to the control motor 6/ through a mechanism, and is moved together around the shaft as shown by the dashed line in FIG. Depending on the position of the leaf stopping plate 59, the depth 9
, wa,... The trajectory of the tea cake that was stirred up changes. That is, a locus as shown by the arrows (1') to 1) corresponding to the symbols (A) to 11qJ added to the leaf stopper plate 11qJ in FIG. 7 is drawn. Then, as the trajectory changes from (a) to (d), the tea confections fall directly below the spindle 7, and the degree of pick-up of the confections increases.

First, it is determined whether control elements such as air volume and spindle rotation speed are to be changed manually or according to established patterns. If you want to do it manually, set the program selection switch S to the "manual" position.If you want to change the program according to the existing pattern, select the appropriate pre-made pattern from "/" to "imaginary" according to the characteristics of the tea cake. Select.

In the case of manual control, all the transitions of the control elements are done manually, and in the case of pattern control, the transition of each control element is patterned and
The control elements are stored in the CFROM, and each control element changes according to the selected pattern. Figure 1/Figure 1 and Figure 1 λ are the same as the patterns described above.
- This shows an example, showing the pattern of amount of heat when "Yu, Wagame, Ichibancha" is selected with the program selection switch 6S. The patterns are shown in the form of a table in Figure 1 and in the form of a graph in Figure 1.

In this example, the entire rough-rubbing process of / is divided into 29 steps, and each step is divided into, for example, "10 from address 00J".
7 memory addresses (mpRo
) is assigned to each memory address, and if the control target value of the control element is ・For example, hot air volume, then "i i 11m3/" J is assigned to address "θ0" and [/
, 3g-Hp/mm J ,...[/BJ address r<'2rr:/m pass, "10" address [x, ρ/+
It is written as nJ. Therefore, for example, "
If the pattern “Ko Wakame, Ichibancha” is selected,
The amount of hot air supplied into the drying chamber changes according to the pattern α in Figure 1 (the transition indicated by the solid line in Figure 1a).Of course, regarding other control elements, as well, what is written in the pattern are similar.

Next, the rough kneading time and the leaf beating time are set by operating the bushing button 67 and the otsu 9.

In this embodiment, the time required for rough rubbing in the existing pattern is only defined by the number of steps: Lq. Therefore, the rough kneading time is set to button A7. , b72, the user decides. Then, the time per step is calculated by dividing the set rough kneading time by the number of steps. For example, if the rough kneading time is set to ++ minutes, the time per step is ll<z( minute) ten koq (step):/,! ;, 2 (minutes). Therefore, if pattern α in Figure 1 is selected and the rough kneading time is set to 11 minutes, the hot air volume will be controlled according to the value stored at address "θ0" until 132 minutes have passed from the start of rough kneading. , /S2 minutes ~ 3,0

Next, pushbuttons 7q□ and 7q□ are operated to set the leaf beating time. In this embodiment, the entire rough rolling process of / is divided into q steps, namely, the leaf beating process, the first rolling process, the third rolling process, and the third rolling process, and the above-mentioned 2q
steps are assigned to each of these processes. 1st
In pattern a in Figure 1, from g00J mountain to “θ7
The steps up to address 1 are the leaf punching process.The 5 steps from OgJ address to address ``00'' are the first rolling process, and the 9 steps from address ``OD'' to address ``15'' are the second rolling process. 7 from address "/6" to address "10" in the process
The total λ9 steps are divided and assigned to each process, such as the third rolling process. and,
When the leaf beating time is set, the setter beating time is divided by the above-mentioned time per step, and the answer is set by the user [7] as the number of steps in the leaf beating process. For example, if the milling time is set to digits and the leaf beating time is set to 71 minutes, the number of leaf beating steps set by the user will be 29-steps. Since this is the same as the number of steps g assigned to the leaf beating process in the pattern α, in such a case, the control elements are changed as is in the selected existing pattern. Inside the microcomputer, "θθ" is stored in the RAM working area.
'' to address ``10'' will be transferred as is.

If the leaf beating time (converted into the number of steps) set by the user is longer or shorter than the leaf beating time in the selected existing pattern, the selected pattern will essentially be rewritten.

Next, the flow of the program in such a case, including the case where the above-mentioned pattern is not changed, will be explained using the flowchart in FIG. 1, FIG. 1, and FIG. ! This will be explained using figures.

(t) (Determine whether the results of the gradient comparison are equal or not. If they are equal, proceed to the next step; if not, jump to the next step.)

Transfer the ready-made pattern (selected pattern) read in O') Cq) to the working area of RAM as it is,
Move on.

(k) Start rough rubbing using the selected pattern as an index.

Now, for example, regarding the air volume, it will change according to the value shown in pattern a in Figure 1 and will be roughly rubbed. Determine whether or not becomes negative, and if ``yes'', proceed to the next step; if ``no'', proceed to (1).

(m) Transfer the number of steps corresponding to the number of steps of the user setter from the first step of the pattern of the leaf beating process in the selected pattern to the working area of the RAM, and proceed to the next step.

For example, the selected pattern is pattern α in Figure 1/Fig.
If the rough kneading time < z < z minutes and the beating time are set to 6 minutes, the number of beating steps on the user setter is therefore ``θθ''
The contents from the address to the address "θ3" are sequentially transferred to the addresses corresponding to the first step to the first step in the working area of the RAM.

(7)) Transfer the pattern of the first culm in the selected pattern to the RAM working area as it is, and proceed to the next step.

That is, the contents from address "0g" to address "θ0" in pattern a are sequentially transferred to addresses corresponding to steps from the fifth step to the ninth step in the working areas of RA and M.

(0) The contents of the first step of the pattern of the first rolling culm in the selected pattern are changed by the minus number of steps (number of user leaf punching steps (4') - number of pattern internal punching steps (g) - +, that is, the step amount is stored in RAM
Then, the pattern of the first rolling culm is transferred as it is to the working area of RAM and proceeds to the first step. to the 73rd step to the address corresponding to 33-, and then from address "θD" to "
/S'' address is transferred in order @ to the addresses corresponding to the first da step to the first da step in the RAM working area.

)) Transfer the pattern of the third rubbing process in the selected pattern to the RAM working area as it is, and proceed to (&).

In other words, the contents from address ``/L'' to address ``10'' are sequentially transferred from the 1st step to the 29th step of the RAM working area.
Transfer to the address corresponding to the step and proceed to (&)'b
o In this case, the "selection pattern" in (k) is (m
) to ψ), that is, the first
/ is the rewriting pattern b in the figure, therefore, the air volume is made to change according to a pattern in which the part indicated by the solid line α/ in the first figure has been replaced with a dotted line.

(q) After transferring the pattern of the leaf beating process in the selected pattern as it is to the RAM working area, the contents of the last step of the pattern are transferred to the RAM by the number of increased steps (number of user leaf beating steps - number of internal pattern beating steps). Continuously transfer to the working area -J4'- and proceed to the next step 3. For example, if the set leaf beating time is 1g, the number of user leaf beating steps is, and from the pattern efflorescence step number g Increase the number of steps・This step becomes the number of increased steps・Therefore・The contents from address “θ0” to address “07” of pattern α correspond to the first step to the second step of LA and M working areas in order. Then, the contents of the box "07" are transferred from the ninth step of the RAM working area to the address corresponding to the first step.

(?-) Transfer the pattern of the first rubbing process of the selected pattern as it is to the RAM working area and proceed to the next O. In other words, the contents from [θ&J point to [θoJ expression The data is transferred to addresses corresponding to the 73rd to 77th steps of the area.

(Evening) Transfer the pattern of the first kneading process in the selected pattern to the RAM working area in the last step corresponding to the number of plus steps fi, ll [i1, and then transfer it to the RAM working area. , which constitutes the first kneading process pattern [0Dji
Of the address “/S” from the location, the number of plus steps (
From the last "/co" address corresponding to "Gestep"
0 (') The contents from the ODJ address to the address "//" are sequentially transferred to the addresses corresponding to steps 1g to 22 of the RAM working area. Transfer the pattern of the 3-rubbing process as it is to the RAM working area) (
Proceed to k) - In other words, RA the contents from address "/Otsu" to address "/a"
Transfer in order to the addresses corresponding to steps from the 23rd step to the 29th step in the M working area, and proceed to (k).
In this case, the "selection pattern" in (k) is Cq)
This is the pattern α modified by ~(1'), that is, the rewritten pattern C in Figure 1/, and therefore the air volume is the same as the 1st.
The transition is made in a pattern in which the solid lines a and 2 in Figure 2 are replaced by 1rt with the dotted chain line C.

As is clear from the above description, in the present invention, several ready-made patterns are prepared as indicators of the transition of control elements in the tea manufacturing and rough rolling process, and these can be selected as appropriate. The rough rolling process of , / is divided into several processes including the first leaf beating process,
Among these, the time for the leaf beating process can be set arbitrarily, and if a leaf beating time that is different from the leaf beating time in the selected pattern is set, the selected pattern itself will be distorted. Therefore, by selecting a ready-made pattern, it is possible to create a transition of control elements with almost no errors, and at the same time, by arbitrarily setting the leaf beating time, it is possible to create a Japanese style that corresponds to infinite variations in tea and sweets. Conditions can be set and the scope of application can be greatly expanded. Additionally, being able to arbitrarily set the phase time further expands the applicability.
In the above embodiment, the case where the control element that changes according to the pattern is the hot air volume has been explained, but in addition to this, other appropriate things such as the spindle rotation speed, the spindle position, the hot air temperature, the tea temperature, etc. can be controlled by the pattern. Of course, you can do it this way.

! ! In Example 2, the roughening step of / is further carried out by q.
Although the process is divided into two steps, the number of steps is not limited to one, and may be at least or more than that.
