BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing silken tofu using a coagulant containing magnesium chloride as a main component.

[0002]

2. Description of the Related Art Conventionally produced tofu is roughly classified into cotton tofu and silken tofu. Cotton tofu is produced by scooping soymilk that has been solidified in a tub with a ladle, laying cotton inside, moving it into a mold box with holes so that the hot water flows out, and dehydrating and pressing. It is a tofu with a textured surface, uneven cross-section, and a rough texture.

[0003] Silky tofu is a gel that hardens soy milk that is so thick that it can be brought together with agar as it is, and is solidified with a coagulant without being dehydrated in a coagulation container with no holes. Silky tofu is smoother in appearance and texture than cotton tofu, and its cross section is as beautiful as egg tofu.

That is, in the case of silken tofu, the amount of water added is set to about 5 times that of the raw material soybeans when the go is boiled. When the amount is 5 times that of the raw soybean, the Brix sugar content is about 12.5%.

When the temperature of the soymilk reached about 70 ° C., silk-cured tofu was produced with calcium sulfate or gluconodelta lactone, which is a slow-acting coagulant, but it is completely impossible to produce it using bitter juice alone. It was It is common knowledge in the industry that if tofu is produced using magnesium chloride, it will be the most delicious tofu. In this case, cotton tofu could be produced, but silky tofu was not.

[0006]

As described above, in the conventional method of producing silken tofu, when fast-acting magnesium chloride is used as the coagulant, the reaction is too fast and the soymilk is coagulated well because the soymilk is thick. Therefore, calcium sulfate is used, which is slow in reaction and is suitable for solidifying the whole soymilk into a gel.

The coagulant gluconodeltalactone is
Compared with conventional coagulants, it is very suitable for the production of silken tofu, is easily soluble in water, decomposes into gluconic acid by heating, and has the effect of coagulating soybean protein in soy milk. Even at a high temperature of ~ 90 ° C, the reaction is slow, so the finished tofu has a smooth texture,
You can get good skin. However, in terms of taste, there are still many problems.

[0008] However, tofu using bitter juice (magnesium chloride) as a coagulant has conventionally been said to be delicious,
Tofu coagulated with calcium sulfate is said to be inferior in taste. In addition, glucono-delta-lactone has the disadvantage that it is nutritionally free of calcium, and if used in a large amount, tofu becomes sour and tasteless.

Further, even if magnesium chloride is used to produce silken tofu, magnesium chloride has a strong coagulation power, and silky tofu has a much higher soymilk concentration than that of cotton tofu. It was impossible for the air bubbles at that time to remain in the silken tofu without being released into the air and to be put on the market.

Therefore, in order to use bitter juice as a coagulant,
A method is used in which soy milk is once cooled to about 20 ° C., bitter juice is mixed with the soy milk, and the mixture is injected into a soy milk coagulation box, and the soy milk coagulation box is heated with steam or the like to coagulate the soy milk. However, this method has drawbacks that it takes a lot of time and labor to cool the soymilk and heats the soymilk coagulation box into which the soymilk is injected, and the equipment cost increases.

In addition, even if any of the above coagulants is used to produce silken tofu, the produced silken tofu is very soft and easily crumbles, which is very inconvenient to cook.

The present invention has been made to solve the above-mentioned problems of the conventional method for producing silken tofu, and uses bitter juice as a coagulant in response to the recent gourmet tendency.
An object of the present invention is to provide a device for producing silky tofu which is delicious and has high nutritional value, which is less likely to collapse than conventional silky tofu and is easy to market without requiring labor for cooling or heating soymilk.

[0013]

[Means for Solving the Problems] The inventor has conducted earnest studies on how to successfully coagulate soymilk by using bitter soup that reacts rapidly with soymilk. As a result, the coagulant can be mixed quickly before the coagulation starts by injecting the coagulant into the soymilk in the soymilk supply pipe, and the coagulation starts immediately when the bitter soup is added to the soymilk. The present invention was completed by finding out that silky tofu can be successfully produced by pouring it into a soy milk coagulation box and immediately stirring it vigorously.

In the apparatus for producing silken tofu according to the present invention, a soy milk tank and an inlet at one end are connected to the soy milk tank via a soy milk supply pump , and an outlet at the other end is downward and horizontal.
And soy milk feed pipe for condensate movably open mouth, a coagulant tank,
A coagulant injection pipe having one end connected to the vicinity of the discharge side of the soymilk supply pipe and the other end connected to the coagulant tank, and the coagulant injection attached to the coagulant injection pipe and linked with the soymilk supply pump. a coagulant-off valve for opening and closing the tube, the flow control valve attached to the coagulant injection pipe, and a stirring plate mounted vertically movably on said discharge port of said milk feed pipe,
The discharge of the milk supply tube with that Kudasu raising the mixing plate
The gist of the present invention is a soybean milk stirring device which stirs soybean milk by reciprocating the mouth to the left and right together with the stirring plate .

[0015]

[Function] First, the stirring plate is raised under the discharge port of the soy milk supply pipe.
It is possible to descend and the discharge port reciprocates left and right with the stirring plate
A soy milk coagulation box is placed at a movable position. Next, when the soy milk supply pump is operated, soy milk is supplied from the soy milk tank to the soy milk supply pipe. When the soy milk supply pump is operated, the open / close valve is opened in association with it.

On the other hand, the coagulant in the coagulant tank is circulated in a coagulant circulation pipe by a circulation pump, and the other end of the coagulant injection pipe is in this coagulant circulation pipe the flow control valve and the on-off valve. Since it is connected via the opening / closing valve, the coagulant adjusted to an appropriate amount by the flow control valve by opening the on-off valve flows into the coagulant injection pipe.

When the coagulant flows into the coagulant injection pipe, since one end of the coagulant injection pipe is connected to the soymilk supply pipe, soymilk is supplied to the soymilk supply pipe, and at the same time, an appropriate amount of the coagulant continues. It is injected into the soy milk flowing through the soy milk supply pipe.

When a certain amount of soy milk is supplied to the soy milk coagulation box, the soy milk supply pump is stopped and the supply of soy milk from the soy milk supply pipe is stopped. When the operation of the soymilk supply pump is stopped, the on-off valve is closed, so that the supply of the soymilk is stopped and the injection of the coagulant from the coagulation injection pipe is stopped at the same time.

On the other hand, when soy milk is injected, the stirring plate is lowered by the soy milk stirring device into the soy milk coagulation box and stands by. As soon as the soy milk supply pipe starts to inject soy milk into the soy milk coagulation box, the stirring device is activated immediately and the soy milk supply pipe discharge port is opened.
Moves back and forth with the stirring plate, so it can be used as a soy milk coagulation box.
The soy milk that flowed in did not need to be interleaved as the soy milk coagulation progressed.
Is stirred.

After moving the soymilk stirring plate to the left and right in the soymilk coagulation box to stir the soymilk, the soymilk stirring plate is pulled up from the soymilk. This agitation separates the air bubbles mixed in the soy milk and gives a moderate shock and agitation to the soy milk, which promotes an appropriate coagulation reaction due to magnesium chloride, which makes the skin beautiful and hard to break and durable. You can
