Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to an apparatus for mixing a coagulant into soybean milk while maintaining proper conditions during tofu production.

BACKGROUND ART Generally, tofu is produced by adding a coagulant such as calcium sulfate or magnesium chloride to soy milk extracted from soybeans and coagulating it by heating. When adding a coagulant to this soy milk, if it is added too quickly or if the temperature is not adjusted properly, coagulation will not occur smoothly and high-quality tofu will not be obtained.
While observing the coagulation state, it is necessary to adjust the amount of coagulant added so as to obtain the desired hardness.

Incidentally, there has recently been an increasing trend toward automation in tofu manufacturing technology, and methods have been realized in which each step of steaming, milking, coagulation, and solidification is performed automatically using a single device. However, in this automation, when adding a coagulant to soymilk at room temperature, coagulation proceeds rapidly and solidifies considerably in the device, making filling difficult and eventually causing blockage. bring about a situation where something happens. To avoid such a situation, attempts have been made to cool the soymilk by transferring it to another container, or to select a coagulant with low activity, but no satisfactory results have been obtained.

Problems to be Solved by the Invention This invention aims to overcome the troubles that occur when mixing soymilk and a coagulant as described above, and to provide a mixing device for soymilk and a coagulant to perform proper coagulation. It was done for a purpose.

Means for Solving the Problems As a result of various studies on mixing devices for soymilk and coagulant, the inventor of the present invention has developed a method for supplying predetermined amounts of soymilk and coagulant to a mixing zone, gradually mixing the two. They discovered that by simultaneously performing forced cooling from the outside, excessive solidification was surprisingly suppressed and a proper mixing state could be obtained, and based on this knowledge they came up with this invention.

That is, this invention consists of a right cylindrical mixing container main body 1 which has a soy milk inlet 2 and a coagulant supply port 3 at the upper part and a soy milk outlet 4 at the lower part and whose upper and lower ends are closed.
, a cooling mechanism 5 disposed on the outer circumferential surface thereof, a circular diagonal plate 9 consisting of a horizontal plate on the shaft circumferential surface erected inside the cooling mechanism 5, and a small circular diagonal plate 1.
The present invention provides a mixing device for mixing soymilk and a coagulant, which is composed of a vertical shaft 7 to which 0... are attached alternately.

Embodiment Next, an embodiment of the mixing device of this invention will be described with reference to the drawings. 1 is a mixing container main body, which is formed in a right cylindrical shape with upper and lower ends closed, and a soybean milk inlet 2 and a coagulant supply port near the upper end. Opposite ports 3 are provided, and a soy milk outlet 4 is provided at the bottom.

A cooling pipe 5 for passing a suitable refrigerant gas is wrapped around the outer circumferential surface of the mixing container main body 1, and the outside thereof is further covered with a heat insulating material 6.

Inside the mixing container main body 1, a vertical shaft 7 for mixing the internal liquid is suspended from its upper end by a suitable fixture 8, and this vertical shaft 7 has an outer diameter that is set on the inner circumferential surface of the mixing container main body 1. A donut-shaped circular ring plate 9 of adjacent size and a small circular ring plate 10 of approximately the same size as the circular hole of this donut are,
The ring-shaped stirring plates 9 are cross-shaped mounting arms, and the small disk-shaped stirring plates 10 are arranged alternately with their centers fixed directly to the vertical shaft 7.

Effects This invention has the above structure, soy milk inlet 2
A constant amount of soymilk and coagulant are supplied through the coagulant supply port 3, cooled by the cooling pipe 5, and the soymilk and coagulant that are merged with each other at the liquid level are transferred to each side board 9 as shown by the arrows. , 10, and is thoroughly mixed, and is continuously taken out from the lower soy milk outlet 4.

It is preferable that the soybean milk inlet 2 and the coagulant supply port 3 are provided at substantially opposing positions. In this way, by setting in advance the supply amount of soymilk as a raw material, the coagulant, and the degree of cooling by the cooling pipe 5 to be constant, it is possible to always obtain an appropriate tofu raw material.

As described above, this invention allows the soymilk and coagulant to be rapidly cooled and mixed immediately before filling the soymilk into the tofu manufacturing equipment. in,
Coagulants such as Calcium Chloride and Calcium Chloride have a fast coagulation speed, and even soy milk that has been cooled in advance may coagulate too quickly due to the heat generated by mixing with the coagulant. However, it was difficult to stabilize the quality of tofu products because uniform coagulation could not be obtained, which was particularly difficult for mass-produced filled tofu products. This makes it easy to improve the taste of tofu and is extremely efficient.
