Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a soybean milk coagulating device, and more specifically, the present invention relates to a soybean milk coagulating device, and more specifically, it includes a reversible rectangular box body and an up-and-down stirring stirring plate in which a stirring plate is reciprocated from side to side within the box body. The present invention relates to a soymilk coagulating device comprising a device.

[Conventional technology]

In the tofu manufacturing process, the work of coagulating soymilk was traditionally done by hand using a shovel and a paddle. This soy milk coagulation process is the most important part of the tofu manufacturing process, and the quality of the tofu is greatly affected by how well the paddle is operated, and this coagulation process requires many years of experience and skill. Met. However, this manual method requires skill to operate the paddle, requires a lot of effort to stir the soymilk by hand, and there is a certain limit to the capacity of the Yose Oke. It is not suitable for automatic mass production of tofu like this.

For this reason, there are devices in which a stirring blade is housed at the tip of the shaft and rotated in a tub (Torako 52-5195), and devices in which a disk with small holes is moved up and down (JP-A-55-1597).
67) etc. have been proposed.

However, in the former case, the soy milk is simply made to flow in the tub, so it is insufficient for the folding operation that requires applying a strong ms to the soy milk. As the soybean milk moves, the hydrostatic pressure causes different impacts on the soymilk when the disk rises and falls, and there are certain limits to the stirring speed, so uniform mixing is not always possible.

Furthermore, when using any of the above methods, a round bucket is used for the folding process, so in order for the soymilk after solidification to penetrate into the mold box, it is necessary to pump it out with a ladle. They have a common drawback: they are inefficient. Various proposals have been made for Ha incorporating this coagulated soy milk, but
There is a hopper-type coagulation tank with a discharge port equipped with a valve at the bottom (Special Publication No. 56-32900), a large number of coagulation packets connected to an endless chain and rotated horizontally,
Invert the packet and take out the coagulated soymilk (II
ll! 1970-32970) Kaal, LkaL, These l[ are to condense one coagulation tank or one packet of coagulated soybean milk into one mold box, so the capacity of the coagulation tank or packet is the same as that of the mold box. Because it is limited by capacity, the capacity of coagulation tanks and packets has to be small.
This necessitates the provision of a large number of small-capacity units, which has the disadvantage of making the device complex and requiring high installation costs.

[Problem that the invention seeks to solve]

The present invention was made in order to solve the problems of soymilk coagulation and first attack process as described above. To provide a soybean milk coagulating device that can efficiently feed coagulated soymilk into a mold box.

[Means for solving problems]

The soybean milk coagulating device of the present invention is provided with a reversing means in a rectangular box with an open top surface, a stirring plate having a stirring plate that reciprocates from side to side within the box, and this stirring device 5!
It is constructed so that it can be raised and lowered above the main body.

[Effect]

Two steady rest wheels 42 that rotate are attached to the upper end surface.Fixing plates 44 are attached to the inner upper portions of the left and right lifting frames 38, respectively. Both ends of the oil sill support member 46 and the two slide shafts 48 are fixed, and are spanned between the left and right fixing members 44 with an appropriate distance in the center.The slider 50 is penetrated by the slide shaft 7) 48. Two slide holes 52 are provided on the left and right sides, and the left and right slide shafts 48 pass through the slide holes 52, so that the slider 50 is supported by the slide shafts 48. The stirring plate 54 is a rectangular plate of an appropriate size for stirring the soymilk by reciprocating from side to side inside the box, and is attached perpendicularly to the lower center surface of the slider 50. A sliding oil sill 56 is mounted on each oil sill support member 46 . The piston stroke of this oil shilling 56 is approximately half of the reciprocating movement of the stirring plate, and the first oil shilling 56a attached to the support member 46 in front is a stirring device! 36 so that the piston rod 58a reciprocates between the left half. - the second one attached to the support member 46b on the stress relief side;
The oil cylinder 56b is attached to the left side of the stirring device 36, and the piston rod 58b is attached so that it reciprocates on the right half. Also, the opening 7 of each oil shilling 56
A bearing 60 is attached to the tip of the door 58, and this bearing 60

Chains 66 are attached to the right and left sides of this locking member 64, and the chain 66a attached to the left side is attached to the sliding teeth 1162a of the F51 oil cylinder 56a from above, and one end of the pond is attached to the left side of the slider 50. .

On the other hand, the chain 66b attached to the cloth side is similarly attached to the sliding gear 62b of the second oil ring 566 from above, and the other end of the chain is attached to the right side of the igu 50. As shown in FIG. 4, the chain 66 is tensioned when the piston rod 58b of the second oil cylinder is fully retracted to the left when the piston rod 58m of the first oil cylinder is fully extended to the left. will be established.

At the upper end of the guide rail 32! ! A bearing 70 for pivotally supporting the lifting shaft 68 is attached.

A turret gear 72 is fixed to a hoisting shaft 68 directly above each elevating frame 38. One guide rail 32
At the bottom of the turret upper gear 72, there are driven teeth #
L74 is pivotally supported. Upper oar gear 72 and driven tooth 117
An endless chain 76 is stretched between the lift frame 38 and the lift frame 38.

The lifting oil cylinder 78 is vertically attached to the upper outer side of the guide rail 32 with a bracket 80. A piston rod 82 of the lifting oil cylinder 78 is configured to stroke downward, and a push gear 86 is pivotally supported at its tip via a fitting 84. This push gear 86
A drive gear 88 is fixed to one end of the hoist shaft 68 directly above the hoist shaft 68, and a hoist arm 90 extends below the drive gear 88 from a fixing plate 44 attached to the elevating frame 38. One end of the hoisting chain 92 is locked to the lower plate 80a, wound around the push-down gear 86, and then raised upward to the drive gear 88! ! 1 and the other end of the chain is fixed to a winding member 90.

Next, soy milk coagulation in this example! 1111, when the lifting oil cylinder 78 is operated to push the piston loft 82 downward, the piston rod 82 pushes down the push-down tooth 3$186, so the turret chain 9
2 is pulled downward and at the same time it is rotated by the wAgh wheel 88 chain 92 and the winding shear 7) 72 is rotated, so the winding @$12 is busy rotating and the endless chain 76
, the lifting frame 38 is lifted by the endless chain 76. When the lifting oil sill 78 is fabricated while the box body 12 is held horizontally and the piston loft 82 is retracted, tI! is applied to the pushing gear 86. The attached hoisting chain 92 is loosened to rotate the drive gear 88, and the hoisting arm 90 is lowered by the weight of the stirring device fi36. At that time, drive +! Rotation of +nL88' The CC upper gear 78 is rotated, the oar upper gear 72 is rotated, and the endless chain 76 is loosened, so that the elevating frame 38 is also suspended and lowered by the rotation of the endless chain 76. When the stirring plate 54 is lowered to a predetermined position inside the box body 12, the lifting oil cylinder 78 is stopped and soy milk and coagulant are introduced into the box body. Sliding oil sill 56b
When the piston rods 58a and 58b are alternately pushed out or retracted, the sliding gear 62 reciprocates left and right, thereby alternately pulling and loosening the left and right chains 66a and 66b. The chain 66g of the first oil sill 56m is attached to the left end of the slider 50, and the chain 66b of the second oil sill 56b is attached to the right end of the slider 50. When pushed out, the slider 50 is moved to the left, so the stirring plate 54 is moved to the left.

At this time, the piston rod 58b of the second oil cylinder is retracted, and the chain 66b on the right side is simultaneously pulled to the left. 1st oil shilling piston loft 5
When the piston rod 88 is pushed out fully to the left, the piston rod 5'8 of the second oil cylinder is pushed out to the right.

Therefore, the chain 661) is pulled to the right and the slider 50
is moved to the right, so the stirring plate 54 is moved to the right. At this time, the piston loft 58a of the PAl oil cylinder is retracted, so the left chain 66a is pulled to the right together with the slider 50. By repeating the above operations, the stirring plate 54 will reciprocate from side to side inside the box 12. Since the guide rail of the elevating frame 38 is fixed to the idlip 34 by the clamp wheels 40 and the steady rest wheels 42, the stirring device 36 does not swing back and forth or left and right even during the stirring operation.

After the stirring plate 54 has been reciprocated a predetermined number of times and with a predetermined strength, the lifting oil cylinder 78 is operated to raise the lifting device 36. After the predetermined maturing time has passed and the soymilk has completely solidified, the reversing oil cylinder 24 is operated to extend the piston loft 26, which pushes the reversing shaft 22 attached to the outer surface 14 of the box upward, so that the soybean milk is completely solidified. As shown in Figure 2, the box 12 is flipped around the bearing 20.The length of the long side of the box 12 is the same as the length of multiple mold boxes, so when flipping the box, If a predetermined number of mold boxes 96 are arranged in advance on the filling table 94, the coagulated soybean milk in the boxes is poured into the plurality of mold boxes in one motion.

In this embodiment, the stirring device fi36 is raised and lowered not only by a hoisting chain 92 attached to a hoisting arm 90, but also by attaching an endless chain 76 rotated by hoisting teeth qL72 to two left and right elevating frames. As a result, the stirring device can be hung in a well-balanced manner on the left and right sides, and its lifting and lowering operations are extremely smooth. The lifting frame 38 also includes two pairs of clamping wheels 40 and two steady rest wheels 42.
Since the idle ribs 34 of the guide rail are sandwiched from three sides, the elevating frame 38 can move up and down the guide rail 32 smoothly, and even when the stirring plate of the stirring device is reciprocating left and right, it can move forward and backward or left and right. It is possible to prevent the stirring device from shaking. Furthermore, the stirring device W136 uses two sliding oil cylinders 56 and alternately pushes out the piston loft to urge the slider 50 and cause the stirring plate 54 to reciprocate from side to side. It is very compact and allows you to freely set the piston's operating speed, number of operations, timing of the stirring plate, etc., allowing you to freely select the stirring conditions according to the temperature, concentration, and other conditions of the soymilk. I can do it.

In addition, in this example, a reversing device is shown in which a shaft is attached to the side of the box body, and the shaft is supported, and the reversing shaft, which is attached separately, is pushed up with an oil sill. The gear is not limited to this, and the gear may be mounted on the shaft and rotated directly by a motor to reverse the rotation. Furthermore, for example, the box may be gripped with a Yose Oke gripper (Utility Model Publication No. 56-027748). It is also possible to have a configuration in which this yoke bucket gripper is inverted and closed.

Also, regarding the stirring device, in this embodiment, two oil cylinders are placed opposite to each other on the left and right, and the piston rod is moved in and out alternately. It can be applied to any type of mechanical device as long as it is flexible and makes reciprocating motion.

Further, the elevating device is not necessarily limited to one in which a gear with a two-inch wire wound around the tip of the piston rod is attached to push down the piston rod, but may be one in which a drive gear is directly rotated by a motor.

〔Effect of the invention〕

As explained above, the present invention coagulates soybean milk using a large-capacity rectangular box, so that soybean fruit can be efficiently produced in large quantities. In addition, since the soymilk is stirred by moving the stirring plate back and forth in a rectangular box, it is possible to stir the soymilk extremely uniformly while applying a moderate impact to the soymilk, resulting in uniform and excellent quality. Tofu! l can be left behind. Furthermore, the anti-I of the box body! Since the width of the side is the width where the mold boxes of multiple cylinders are lined up, the soymilk after coagulation has the excellent effect of being able to detect the mold boxes of multiple cylinders in one motion at the same time by reversing the box body.

Also, stir! Since the 1ffi is designed to be able to move up and down, it is possible to perform the soybean milk mixing and mixing operations smoothly and efficiently.
