[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for coagulating soybean milk.

0002

[Prior art] To produce tofu by coagulating soy milk,
It is necessary to add a coagulant to soy milk and stir it. Conventionally, the so-called yose-mixing process for coagulating soymilk involves injecting a coagulant into a coagulating can or yose-oke in advance, and then pouring the soymilk vigorously over it, or adding the curdling agent to the soymilk poured into the yose-oke. The method used was to vigorously stir the mixture after adding it.

0003

[Problem to be Solved by the Invention] However, when using the former method in which a coagulating agent is injected into the coagulating can in advance,
Since the soymilk is injected vigorously, the soymilk scatters and sticks to the coagulating can, which requires a lot of effort to clean the coagulating can.

[0004] In addition, both when using the former method and when using the latter method in which the soymilk is strongly stirred after adding a coagulant, the soymilk foams during supply and coagulation, making it unnecessary to scrape and remove the foam. There are problems in that not only is it necessary, but also product quality and product yield are reduced.

[0005] Furthermore, with either method, if the soymilk temperature rises above a predetermined range, coagulation will begin during stirring, making it extremely difficult to control the soymilk temperature.

The present invention was made in order to solve the above-mentioned problems of the conventional soybean milk coagulation method, and there is no scattering of soymilk when pouring soybean milk into the coagulation can, reducing the time and effort of cleaning the coagulation can, and the soybean milk coagulation method. It is an object of the present invention to provide a soybean milk coagulating method and an apparatus therefor, in which soymilk does not foam during injection and soymilk coagulation, and the temperature of soymilk can be easily controlled.

[0007]

[Means for Solving the Problems] The gist of the soybean milk coagulating method of the present invention is to supply soymilk to a coagulating container via a soymilk supply pipe and to inject a coagulant into the soymilk flowing through the soymilk supply pipe.

[0008] The soymilk coagulating apparatus of the present invention also includes a soymilk tank, a soymilk supply pump, a soymilk supply pipe connected to the soymilk tank via the soymilk supply pump, a coagulant tank, and a circulation pump. A coagulant circulation pipe that circulates the coagulant in the coagulant tank, and an on-off valve that has one end connected to the soymilk supply pipe and the other end that opens and closes in conjunction with a flow rate control valve and the soymilk supply pump. The gist is that it consists of a coagulant injection pipe connected to a coagulant circulation pipe.

[0009]

[Operation] In the soymilk coagulation method of the present invention, when the coagulant is injected into the soymilk flowing through the soymilk supply pipe, the soymilk mixed with the coagulant is sufficiently stirred within the soymilk supply pipe.
Soy milk is sufficiently coagulated without vigorously stirring the soy milk by pouring it into a coagulating container. Therefore, the outlet of the soymilk supply pipe can be immersed in the injected soymilk immediately after the soymilk is poured into the coagulation container, which prevents the soymilk from foaming and prevents the soymilk from scattering into the coagulation container when pouring soymilk. few. In addition, coagulation is possible at high temperatures, making it easy to control the temperature of soymilk.

In the soymilk coagulating apparatus of the present invention, soymilk is supplied from the soymilk tank to the soymilk supply pipe when the soymilk supply pump is operated. When the soy milk supply pump is operated, the on-off valve is opened in conjunction with the operation.

On the other hand, the coagulant in the coagulant tank is circulated through a coagulant circulation pipe by a circulation pump, and the other end of this coagulant circulation pipe has a flow rate control valve and an on/off valve. Since the coagulant is connected through the coagulant injection pipe, when the on-off valve is opened, an appropriate amount of coagulant is regulated by the flow control valve and flows into the coagulant injection pipe.

[0012] When the coagulant flows into the coagulant injection pipe, one end of the coagulant injection pipe is connected to the soy milk supply pipe, so at the same time soy milk is supplied to the soy milk supply pipe, an appropriate amount of coagulant is continuously supplied. and is injected into the soymilk flowing through the soymilk supply pipe.

[0013] Once a certain amount of soymilk has been supplied to the coagulation container, the soymilk supply pump is stopped, and the supply of soymilk from the soymilk supply pipe is stopped. When the operation of the soymilk supply pump is stopped, the on-off valve is closed, so that the injection of coagulant from the coagulation injection pipe is also stopped at the same time as the supply of soymilk is stopped.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of one embodiment of the device of the present invention. The base end of the soy milk supply pipe 10 is connected to the soy milk supply pump 1.
2 to the bottom of the soy milk tank 14.

[0015] Furthermore, the tip of the soymilk supply pipe 10 is a movable part 10a that is bent downward.
a is rotatably connected by a universal elbow 16, and a discharge port 10c at the tip can be moved up and down above the coagulation container 20 by a cylinder 18.

A chuck valve 22 is installed near the tip of the soymilk supply pipe 10 to prevent the soymilk remaining in the soymilk supply pipe 10 from flowing back when the soymilk supply pump 12 is stopped after supplying soymilk. There is.

A coagulant circulation pipe 28 equipped with a circulation pump 26 is connected to the coagulant tank 24, and the coagulant suspended in water is constantly circulated through the coagulant circulation pipe 28. There is.

The proximal end of the coagulant injection pipe 30 is connected to the coagulant circulation pipe 28 via a flow control valve 32 and an on-off valve 34, and the distal end is connected to the movable part 10a of the soymilk supply pipe 10.
attached to the bent side of the The on-off valve 34 attached to this coagulant injection pipe 30 is adapted to operate in conjunction with the soy milk supply pump 12.
The on-off valve 34 is opened at the same time as the motor 2 rotates, and closed at the same time as the motor 2 is stopped.

The operation of the apparatus of this embodiment will be explained. Initially, the movable part 1 of the soy milk supply pipe 10 is moved by the cylinder 18.
0a is standing up. When the coagulation container 20 is set in position, the cylinder contracts and the movable part 10a is lowered. At this time, the discharge port 10c at the tip stops near the bottom of the coagulation container 20.

When the soy milk supply pump 12 is operated, soy milk is supplied from the soy milk tank 14 to the soy milk supply pipe 10. When the soybean milk supply pump 12 is operated, the on-off valve 34 is opened in conjunction with the operation.

On the other hand, the coagulant in the coagulant tank 24 is circulated through a coagulant circulation pipe 28 by a circulation pump 26, and the proximal end of the coagulant injection pipe 30 is connected to the coagulant circulation pipe 28 to provide a flow rate. Since they are connected via the control valve 32 and the on-off valve 34, when the on-off valve 34 is opened, the coagulant adjusted to an appropriate amount by the flow rate control valve 32 flows into the coagulant injection pipe 30.

When the coagulant flows into the coagulant injection pipe 30,
The tip of the coagulant injection pipe 30 is connected to the movable part 10 of the soymilk supply pipe 10.
a, so that at the same time soy milk is supplied to the soy milk supply pipe 10, an appropriate amount of coagulant is continuously supplied to the soy milk supply pipe 1.
It is injected into the soy milk flowing through 0.

When the coagulant is injected into the soymilk flowing through the soybean milk supply pipe 10, the soymilk mixed with the coagulant is sufficiently stirred in the soybean milk supply pipe 10, so that the soymilk is vigorously injected into the coagulation container 20. The soy milk coagulates sufficiently without stirring the soy milk vigorously. Therefore, immediately after the soybean milk is injected into the coagulation container 20, the injected soybean milk is transferred to the outlet port 10 of the soybean milk supply pipe 10.
Since the soybean milk can be immersed by the operation of the cylinder 18, foaming of the soymilk is prevented, and soymilk is less likely to scatter into the coagulation container 20 when pouring the soymilk.

Once a certain amount of soymilk has been supplied to the coagulation container 20, the soymilk supply pump 12 is stopped, and the soymilk supply pipe 1 is stopped.
The supply of soy milk from 0 is stopped. At this time, the chuck valve 22 prevents the soymilk remaining in the soymilk supply pipe 10 from flowing back. When the operation of the soymilk supply pump 12 is stopped, the on-off valve 34 is closed, so that the injection of coagulant from the coagulation injection pipe 30 is also stopped at the same time as the supply of soymilk is stopped.

After stopping the supply of soymilk, the cylinder 18 is operated to raise the movable part 10a, and the soymilk at the tip flows out. Note that it is preferable to adjust the position of the movable portion 10a so that the last droplet comes out of the coagulation container.

[0025]

Effects of the Invention As described in detail above, the soymilk coagulating method and soymilk coagulating apparatus of the present invention connects a coagulant injection pipe to a soymilk supply pipe, supplies soymilk to a coagulating container via the soymilk supply pipe, and soybean milk. This system is characterized by injecting a coagulant into the soymilk flowing through the supply pipe, and since the soymilk mixed with the coagulant is sufficiently stirred within the soymilk supply pipe, the soymilk can be vigorously injected into the coagulation container. Even if you don't stir the soy milk vigorously,
Soy milk is sufficiently coagulated. Therefore, the outlet of the soymilk supply pipe can be immersed in the injected soymilk immediately after the soymilk is poured into the coagulation container, which prevents the soymilk from foaming, saves the trouble of removing bubbles, and improves the product yield. Since soybean milk is less likely to scatter into the coagulation container during injection, the effort of cleaning the coagulation container can be omitted. Furthermore, high-temperature coagulation is possible, and the temperature of soybean milk can be easily controlled.
