A heating means that applies a heating effect with a strength corresponding to the time of boiling, keeping warm, etc., and a heating means that applies a heating effect to the soybean milk in the mold container fed to the soybean from the time of boiling.
During the molding process, a stirring means that provides a stirring action is used, and when the boiled soymilk is cooled to a predetermined temperature, the soybean milk is tilted to mix the water and coagulant contained inside the soymilk in the mold container. The main component is a means for introducing the coagulant to be introduced.

According to the present invention, a series of tofu manufacturing processes from crushing soaked soybeans and separating soybean milk and okara to coagulating and molding soymilk can be performed continuously and automatically without human intervention. Therefore, tofu can be manufactured easily and in a short time at home without requiring any skill. Also, since there is no manual intervention,

Next, the sequence of manufacturing tofu using the apparatus of this embodiment configured as described above will be explained.

First, a predetermined amount of soybeans soaked in water is put into the centrifugal separation tank 13 together with water, and when a start switch (not shown) is turned on, the motor 43 of the moving mechanism 40 is turned on.
is driven by a predetermined amount in a predetermined direction, and as shown in FIG.
Press down. Then, one end of the swing arm 31 swings upward about the fulcrum, and the push-up rods 33,
33 is moved upward via the support plate 32. When the push-up rods 33, 33 move upward, the centrifugal separation tank 13 is biased at one end thereof and rises from the vicinity of the bottom of the liquid storage case 12 to a predetermined height. When the centrifugal separation tank 13 rises, the clutch plates 131 and 221 are separated, and the connection between the centrifugal separation tank 13 and the drive shaft 22 is released. At that time, the locking piece 161 of the upper lid 16 and the inner lid 2
The locking pieces 281 of No. 8 are engaged with each other to lock the centrifugal separation tank 13 in a stopped state.

Next, the motor 20 is driven, and the crushing blade 27 is rotationally driven in the direction shown by the arrow 100 in FIG. As a result, the soybeans inside the separation tank are finely ground. Thereafter, when the crushing of the soybeans is completed after a predetermined period of time has elapsed, the motor 20 is stopped and the rotation of the crushing blade 27 is stopped. Next, the motor 4 of the moving mechanism 40
3 is driven by a predetermined amount in the opposite direction to the above, and the shaft 311 of the swing arm 31 is driven by the clutch cam 461.
is released. Then, swing arm 3
One end of 1 swings downward and returns to push-up rod 3.
3 and 33 are lowered and returned. As a result, the centrifugal separation tank 13 descends to near the bottom of the liquid storage case 12,
The clutch plates 131 and 221 are joined together, and the centrifugal separation tank 13 is connected to the drive shaft 22 (see FIG. 2). Thereafter, the motor 20 is driven, and the centrifugal separation tank 13 is rotated together with the crushing blade 27 in the direction of the arrow 100. Then, the crushed soybeans in the centrifugal separation tank 13 are separated into okara and soy milk by the centrifugal action, and while the okara remains attached to the filter 90, the separated soy milk is transferred to the filter 9.
0 and pores 131... through the liquid reservoir case 12
The soybean milk flows out from the bottom, passes through a discharge port 17, is stored in a soybean milk receiver 18, and then is stored in a mold container 14 via a discharge port 19.

Next, the motor 43 of the moving mechanism 40 is driven,
The rotating arm 45 rotates about the rotating shaft 41 in the direction indicated by an arrow 101 in FIG. Along with this, the mold container 14 moves along a predetermined path on the guide rails 47, 47 together with the heat-insulating outer cylinder 15 and the outer frame 46, and is sent to the extension cylinder 510 above one side of the outer frame 46. As shown in the figure, it is fitted and connected to its lower part via a packing 540. At the same time, the stirring body 520 is inserted to the vicinity of the bottom of the mold container 14. As a result, the mold container 14 is set in the heating position as shown by step ○ in FIG.

Next, in Step ○, the sheathed heater 47 is energized and heated to 100% by a signal from the control circuit 80, and at the same time, the solenoids 610, 6 of the drive mechanism 60 are turned on.
10 is driven on and off alternately at a constant cycle, and the stirring body 520 is driven reciprocally between one direction and the other direction while sandwiching the neutral position where it hangs downward (Step C). As a result, the soybean milk in the mold container 14 is heated while being stirred, and boiling of the soybean milk is started. In this case, the driving cycle of the agitator 520 is set to approximately T=0.7 to 0.8 seconds, and the soymilk in the mold container 14 is heated while being gently stirred. This makes the temperature distribution of the soymilk in the mold container uniform throughout. In addition, fine bubbles in soymilk generated during pulverization are reduced. Thereafter, when it is detected that the temperature of the soymilk has reached 96°C to 97°C in step ○2 after a predetermined period of time has elapsed, the energization to the sheathed heater 48 is canceled by a signal from the control circuit 80 in step ○e. Ru.

When the sheathed heater 48 is de-energized, the cycle of drive pulses applied to the solenoids 610, 610 of the drive mechanism 60 changes from T=0.7 to 0.8 seconds to T=
Switched to 0.5 seconds. Therefore, the stirring body 520
is driven back and forth at a fast cycle and speed. As a result, the soybean milk in the mold container 14 is stirred at a rapid cycle, thereby preventing boiling over and burning on the bottom surface. Next, in step ○, the motor 43 of the moving mechanism 40 is driven by a predetermined amount in response to a signal from the control circuit 80, and the rotating arm 45 is rotated by a predetermined angle in the opposite direction to that described above. As a result, the mold container 14 moves downward to the point P shown in FIG. 6 with respect to the extension cylinder 510,
A gap of approximately 5 mm is formed between the two (step ○chi).

When a gap is formed between the extension tube 510 and the mold container 14 in step ○, the period of the drive pulse applied to the solenoids 610 and 610 is switched from T=0.5 seconds to T=0.7 seconds in step ○. . Therefore, the agitator 520 is driven back and forth at a fast cycle and speed. As a result, the soybean milk in the mold container 14 is gently stirred and a cooling process is performed. At this time, by forming the gap as described above, cooling of the soymilk is further promoted. During this stirring process during cooling, the bubbles that had formed on the surface of the soymilk disappear. Also, the generation of sludge is prevented.

When the soybean milk is cooled to the coagulation temperature in step ○, the operating mode of the apparatus is selected in step ○ in accordance with the mode previously designated by the type of coagulant to be added to the soymilk.

For example, if the coagulant used is GDL (glucono delta lactone), the GDL of the step
If the mode is CaSO ₄ (calcium sulfate), the CaSO ₄ mode of step O is selected, and if it is bitter, the bitter mode is selected. In addition, here we will explain an example using GDL as a typical coagulant, but even if other coagulants are used, soymilk can be coagulated and molded using almost the same process steps as described below. Needless to say, it can be done. In that case, the temperature at which the coagulant is added, the degree of energization of the sheathed heater 48, the stirring time of the soymilk by the agitator 520, the time to keep the tofu warm, the temperature, etc. described below may be modified and set according to the coagulant used. Of course.

Figure 8 shows that the operating mode of the device is at step ○nu above.
A flowchart showing the process procedure when GDL mode is selected is shown.

The temperature of soy milk is approximately 82℃ at step ○I shown in Figure 8.
When the temperature is cooled down, the sheathed heater 48 is
is heated by electricity at a level of 10%.

Next, in step ○c, solenoids 610, 610
The period of driving pulses applied alternately to T = 0.7
The period is changed from seconds to T=0.3 seconds, and the reciprocating period of the stirring body 520 becomes faster. As a result, the soymilk in the mold container 14 is agitated more intensely at a faster rate and cycle.
Under these conditions, soymilk is coagulated and molded as follows.

First, in step C, the stirring cycle of soymilk by the stirring body 520 is switched to "fast/strong", and at the same time,
The motor 43 of the moving mechanism 40 is driven to rotate normally, and the rotation of the rotation arm 45 causes the extension tube 510 to move into the mold container 1.
4 to the required height relative to the frame 110. As a result, the engagement with the locking plate 720 is released, and the coagulant container 710 of the coagulant injection means 70 is released.
is tilted downward about a fulcrum inside the extension tube 510 as indicated by an arrow 104. Then, the water that had been stored separately in the coagulant container 710 and
The soybean milk is poured into the mold container 14 while being mixed with GDL. The added coagulant is evenly distributed in the soymilk by the stirring action of the stirring member 520, and is uniformly stirred and mixed. This stirring by the stirring body 520 is continued for about 15 to 17 seconds.

Next, in step O, energization of the solenoids 610 and 610 is simultaneously canceled at the neutral position according to a command from the control circuit 80. As a result, the stirring body 520
stops at a neutral position pointing vertically downward, stopping the flow of soy milk. After that, move the moving mechanism 40 to step ○.
By controlling the drive of the motor 43, the mold container 14 moves from the above position P to a position Q further below.
As shown by the imaginary line in the figure, it is set at the soy milk insulation/cooling position. Next, in step O, the soybean milk in the mold container 14 is heated and kept warm for about 15 minutes by the heating action of the sheathed heater 47, and after being kept warm for the required time, it is cooled to the coagulation temperature. At this time, since a heat storage space is formed between the mold container 14 and the heat-retaining outer cylinder 15, the soymilk in the mold container is heated not only from the bottom but also from its entire surface, ensuring good heat retention. I can do it. When this heat retention process is completed, the sheathed heater 47 is turned off in step ○, and then the soybean milk in the mold container is allowed to cool for about 25 minutes in step ○, and is molded. Next, in step ○nu, mold container 14
is transferred to the soybean milk storage position via the rotating arm 45 along the guide rails 47, 47 by the drive of the motor 43 of the moving mechanism 40. Thereafter, when the mold container 14 is taken out from the storage position and molded in cold water, the production of soymilk is completed.
