DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus and method for dehydrating gel-like soymilk in the production of tofu (momen tofu), etc., for example, by molding into a box.

[Conventional technology]

For example, to produce momen tofu (in some cases, soy milk mixed with a coagulant (bitter) and made into a gel is filled into a mold box,
This gel-like soymilk is pressed and molded to make molded tofu.

Figure 4 shows a schematic configuration of a conventional dehydration device for compressing and molding gel-like soymilk.
Soy milk tank made of steel plate or aluminum plate provided with
is the piston rond of the air cylinder 4 fixed to the support plate 5; is the attached cover plate.

In the conventional dehydration device CG configured as described above, first, two cotton cloths 6 are spread on the top and side surfaces of the bottom plate of the soybean milk tank 1 (= soymilk 7 mixed with a coagulant and made into a gel). Inject a certain amount of gel-like soymilk 7, cover the top of this gel-like soymilk 7 again with cotton cloth 8, and in this state place the soymilk tank 1 under the lid plate 6 (:
Install.

Next step: Compressed air is supplied from the air cylinder 4c congrets f (not shown), and a constant load is applied to the entire upper surface of the air cylinder 4 (twisted gel-like soymilk 7) through the lid plate 5.
The gel-like soymilk 7 is dehydrated, compressed, and molded.

[Problem that the invention seeks to solve]

In the conventional dehydration device as described above (2), it is necessary to apply a constant load to the inner arc of the soybean milk tank 1; Moreover, the air cylinder 4 and the like for pressurizing the soybean milk tank 1 are large in size, making it difficult and time-consuming to attach and remove the soybean milk tank 1.

In addition, when applying a load with the air cylinder 4, it is difficult to control the magnitude of the load applied to the gel-like soymilk 7 and the squeezing speed because the air supplied by the air cylinder 4 is compressible. size.

The pressing speed is important (the hardness of the momen tofu that becomes the product)
: There is also the problem of bringing about change.

Furthermore, during dehydration, the amount of water drained is soy milk tank 1 (:
The amount of injected gel-like soymilk 7 is 174 to 115, and this water not only drains from the hole 2 in the bottom plate of the soymilk tank 1, but also overflows from the side of the lid plate 3 at the top of the soymilk tank 1. This wastewater is then drained onto the floor (2). If this wastewater is left unattended, it not only worsens the working environment, but also causes pollution by contaminating groundwater and contaminating well water (2), so it is necessary to treat the wastewater. .For this reason, equipment for collecting the waste water on the floor in a separate tank C is required, which poses the problem of requiring a large amount of equipment and operating costs.

This invention has been made in order to solve the above problems (1), and is a dehydrating device for gel-like soymilk that is capable of dehydrating gel-like soymilk using simple equipment, and also facilitates wastewater treatment. The purpose of this paper is to propose methods and methods.

[Means for solving problems]

The dehydration device for gel-like soymilk according to the present invention is equipped with a mold box, a dehydration tank, and a vacuum pump. The dehydration tank engages with the mold box and dehydrates the gel-like soymilk filled in the mold box by depressurizing and suctioning the inside of the mold box.The vacuum pump connects the dehydration tank and the buffer. The water is removed through the tank and the pressure inside the dehydration tank is reduced.

Furthermore, in the method for dehydrating gelled soymilk according to the present invention, after filling a soybean milk tank with gelled soymilk and fitting a lid, the pressure is reduced from above or below the soybean tank using a vacuum pump via a buffer tank. This method involves suctioning and introducing the wastewater into a dehydration tank.

[Effect]

In this invention, since the gel-like soymilk is dehydrated by vacuum and suction, the suctioned waste water can be easily recovered and the dehydration rate can be easily adjusted.

〔Example〕

FIG. 1 is a schematic configuration diagram showing an embodiment of the present invention.
In the figure, 10 is a soybean milk tank with an opening at the bottom and a removable bottom plate 11 with many small holes, and 12 is a soybean milk tank with one side or an empty claw that fits on the top of the soybean milk tank 10. This is a dehydration tank having a drain hole with a -1 stroke dimension and a drain pulp 14 at the bottom. 17 is a vacuum pump, 18 is a buffer tank connected to the dehydration tank 13 and the vacuum pump 17 through piping, and is a manual pulp with a drain pulp 19 attached to its lower part.

Soy milk tank 1 of the gel-like soy milk dehydration device configured as described above
0, the details of the relationship between the cover plate 12 and the dehydration tank 13 are shown in FIG. As shown in FIG. 2, the space between the soybean milk tank 10 and the lid plate 12 is sealed with a soft sealing material 21 such as a rubber plate. Similarly, sealing material 2 is placed around the suction water of the dehydration tank 13.
2 is stretched around to seal between the dehydration tank 13 and the soybean milk tank 10 when the soybean milk tank 10 is set on the upper surface of the dehydration tank 16.

In the gelled soymilk dehydration apparatus described above, cotton cloth 6 is spread over the inner lower surface and side surfaces of the soybean milk tank 10 containing the bottom plate 11. The cotton cloth 6 is made of cotton or other suitable fibers and serves as a filter cloth. Next, a fixed amount of gel-like soymilk 7 mixed with a coagulant, which is a raw material, is injected, and the upper part is also covered with a cotton cloth 8.
After covering it with the lid, cover plate 12 is placed on it. In this state, soy milk tank 10
is set on the top of the dehydration tank 13 and dehydrated by the vacuum pump 17 via the buffer tank 18! The inside of 13 is made into a suction vacuum. The buffer tank 18 is provided to protect the vacuum pump 17 by preventing waste water from being sucked into the vacuum pump 17 and to buffer pressure.

As the inside of the dehydration tank 16 is suctioned by the vacuum pump 17, the pressure inside the soymilk tank 10 is also reduced, and the moisture in the gelled soymilk 7 is sucked into the dehydration tank 13, and as the degree of vacuum inside the dehydration tank 13 improves. , the lid plate 12 fitted into the soybean milk tank 10 gradually descends to squeeze the gelled soymilk 7. In this case, the internal pressure of the lid plate 12 becomes low due to the suction in the soybean milk tank 10, and it is pushed down by the external atmospheric pressure, so it is sufficient that the lid plate 12 has enough strength to withstand the atmospheric pressure at the time of suction. The weight of 12 itself is not required and can be made lighter.

In addition, the degree of vacuum in dehydration [13] during squeezing differs depending on the type of product after dehydration, i.e. tofu with low hardness or fried tofu with high hardness, but the amount of gelled soymilk 7 and the type of product after dehydration are constant. In this case, the degree of vacuum va (WtPnAq) is
The area S (cd) is determined by the following equation.

v a =s W L Here, W is the load (Kf) applied to the lid plate 12 during dehydration, and is determined from experience depending on the type of product after dehydration. Further, L is the value of atmospheric pressure expressed in water columns (-1 to 111).

Therefore, by adjusting the opening degree of the manual pulp 2o provided between the dehydration tank 16 and the buffer tank 18, it is possible to obtain a degree of vacuum depending on the type of product after dehydration.

The dehydration time varies depending on the amount of gelled soymilk 7 injected into the soybean milk tank 1o and the type of product after dehydration, but as a result of experiments, when about 3 breasts of gelled soymilk 7 is dehydrated to make raw tofu, it takes longer than conventional While the pressurization time was about 40 minutes, it was about 10 minutes in this example.

After dehydrating the gelled soymilk 7 in the soybean milk tank 1o as described above, the vacuum pump 17 is stopped, the vacuum breaker 16 attached to the dehydration tank 13 is opened, and the dehydration tank 13. soy milk tank 10
Bring the inside to atmospheric pressure. Thereafter, the lid plate 12 is removed from the soybean milk tank 1o, the tofu is sent to the next process, and the drain pulp 14 of the dehydration tank 16 is opened to collect the dehydrated water into the waste water treatment tank.

In the above embodiment, the gelatinous soybeans %7 were dehydrated from below the soybean milk tank 1o, but as shown in FIG. Dehydration can be performed.

In FIG. 3, 26 is the cover plate 12 of the above embodiment and the dehydration [
The lid box 23 has a large number of small holes at the bottom, and is connected to the vacuum pump 17 and the buffer tank 18 by piping through manual pulps 24 and 25, respectively. In this case, the vacuum pump 17 is protected by providing the tip of the piping connected to the vacuum pump 17 above the tip of the piping connected to the buffer tank 18.

Connected via the movable pulp 26 ◇ When dehydrating the gelled soymilk 7 placed in the soybean milk tank 1, close the manual pulp 25 and drive the vacuum pump 17 with the manual pulp 24° 26 open. The pressure inside the lid box 23 and the buffer tank 18 is reduced to create a vacuum. Due to the reduced pressure in the lid box 26, the lid box 23 is lowered, compressing the gelled soymilk 7, and the water in the gelled soymilk Z passes through the small hole in the bottom of the lidding box 23.
Go inside. After a predetermined suction time has elapsed, the manual pulp 24 is closed, the manual pulp 25 is opened, and the water that has entered the lid box 26 is collected into the buffer tank 18. That is, in the case of this embodiment, compression and drainage can be performed in two steps, and the optimal compression time for products such as tofu and aburaage can be arbitrarily selected.

Thereafter, as in the first embodiment, the inside of the lid box 23 is opened to the atmosphere, the tofu is taken out, and the buffer tank 18 is removed.
Collect wastewater inside.

In each of the above-mentioned embodiments, the pulp operation and vacuum operation can be automated to save labor and perform similar operations.

〔Effect of the invention〕

As explained above, this invention has the following effects because gel-like soymilk is dehydrated by vacuum suction.

■Since gel-like soymilk can be dehydrated only by pulping, the equipment is simple and the operation is also easy.

(2) During dehydration, it is easy to adjust the degree of vacuum and dehydration time, and dehydration suitable for each product can be repeated, thereby making it possible to stabilize the product.

■Since dehydration time can be shortened, manufacturing man-hours can be reduced.

■Since the wastewater is collected in a dewatering tank or a buffer tank and does not need to be released, it is easy to collect the wastewater and the working environment can be improved.
