Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a continuous automatic manufacturing method for silken tofu. [Prior Art] Silk tofu is soft and easily broken, so it has been difficult to produce it continuously using an automatic machine. For this reason, silken tofu is made by mixing soymilk with the required amount of coagulant, placing it in a predetermined mold, allowing it to stand at a temperature at which the soymilk coagulates for a certain period of time, and after completely coagulating, pouring it into water and forming it into a predetermined size. It is cut into pieces and then packaged. Furthermore, apparatuses for continuously coagulating soybean milk are disclosed in Japanese Patent Application Laid-open No. 12282/1982 and Japanese Patent Publication No. 41550/1982. This system divides the inside of a gutter-shaped coagulation tank with a partition plate provided in a chain, and coagulates soymilk while moving this partition plate. [Problem to be solved by the invention] Therefore, the soymilk put into the coagulation tank has a relatively low temperature of 65°C, and it is transported through the tank by a partition plate and is treated with a coagulant in the coagulation section. The mixture is mixed and stirred and coagulated in the coagulation reaction section. Therefore 65℃
It takes a long time to coagulate soymilk as it is, and the coagulation may be uneven. In addition, a portion of the coagulated tofu adheres to the partition plate, etc., causing chips in the tofu when it is transferred into the tank or sent out of the tank. When producing firm tofu, the solidified tofu is destroyed and then dehydrated under pressure and recombined, so there is no problem even if the tofu is chipped or damaged when sent out from the coagulation tank, but the solidified tofu In the case of silken tofu that is used as a product as it is, chips due to adhesion to the partition plates impair the product value. Therefore, even if relatively hard firm tofu can be produced using an automatic machine, it is not suitable for producing soft and brittle silken tofu. [Means for solving the problem] An appropriate amount of coagulant is mixed into soybean milk of a required concentration obtained by squeezing soybeans, stirred, and supplied to a coagulation process consisting of a trough-shaped coagulation tank. The temperature is adjusted to such an extent that the soymilk does not coagulate, and the required amount of soymilk is divided and continuously sent out, and at the front of this coagulation process, the liquid level of the soymilk in each compartment is adjusted. The soybean milk comes to a standstill and is transported in a stable manner in sequence according to the transport means.Furthermore, after this, the rear part of the coagulation process is heated to the extent that the soymilk coagulates, and the soybean milk is coagulated while being transported to produce silken tofu. Manufacture continuously. [Example] Next, the continuous manufacturing method of silken tofu of the present invention will be explained with reference to the example shown in the drawings. In the figure, 1 is a silken tofu continuous manufacturing machine, and there are many partitions 12 in a trough-shaped coagulation tank 11 with a total length of 6 to 18 m.
The conveyor means protrudes from the endless chain 13 at fixed pitches of approximately 100 mm to 150 mm in length for one block of tofu. The chain is driven slowly so that the soymilk can coagulate without breaking its shape, that is, one pitch of the partition plate is heated for 15 seconds to 22 seconds.
The required amount of soybean milk and an appropriate amount of coagulant (15 g/ 3) is injected and stirred. The soymilk temperature at this time is a temperature (65°C to 74°C) at which the soymilk does not coagulate with the coagulant. Magnesium chloride, calcium sulfate, glucone, etc. are used as coagulants, and these coagulants are used by appropriately mixing them, and the ratio of coagulants is determined based on the soymilk temperature at the time of feeding into the coagulation tank. The relationship is as follows.

〔Effect of the invention〕

As described above, according to the present invention, when soymilk mixed with a coagulant is poured into a coagulation tank, after maintaining the temperature at which the soymilk does not coagulate until it is stably transferred,
With a stable supply of soymilk, the system is now able to heat the soymilk to the temperature at which it coagulates, so even soft and fragile silken tofu can be stably transferred through the coagulation tank, allowing the tofu to be separated from the partition plate, tank side plate, and bottom plate. This improves the water repellency between the outer surface of the tofu and the outer surface of the tofu, which has the effect of automatically and continuously producing tofu with a beautiful external shape without damaging the tofu and without loss.

Claims (1)

[Claims] 1 An appropriate amount of coagulant is mixed into soymilk of the required concentration obtained by squeezing soybeans, stirred, and fed to a coagulation process consisting of a trough-shaped coagulation tank. The required amount of soymilk that has been adjusted and put in is divided into sections and continuously sent out, and at the front of this coagulation process, the liquid level of the soymilk put in each compartment is kept still, and the liquid level is adjusted according to the conveying means. After that, the soybean milk is heated in the latter part of the coagulation process to the extent that the soymilk coagulates, and the soybean milk is coagulated while being conveyed to continuously produce silken tofu. Continuous automatic manufacturing method for silken tofu.
