Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for transferring matte tofu (hereinafter referred to as tofu mat) that has been coagulated into a thick layer and a predetermined shape in an automatic soymilk coagulation tank to a cutting process. This invention relates to an overturning device for tofu mats that overturns them in hot water.

[Conventional technology]

JP-A-50-12282 discloses an apparatus for automatically producing tofu by mixing and coagulating soy milk with a coagulant. In this system, soymilk mixed with a coagulant is supplied to one end of a trough-shaped coagulation tank, and this soymilk is transferred by moving a large number of partition plates on an endless chain arranged in the longitudinal direction of the tank, and is transferred to the coagulation zone of the tank. The material is solidified through successive stages such as , coagulation zones, etc., and then sent out from the other end of the cypress.

[Problem to be solved by the invention]

Devices that automatically coagulate soymilk generally coagulate the soymilk layer fed into the coagulation tank so that the thickness of the soymilk layer is approximately the same as the thickness of tofu cut into regular shapes when packed into packages. This is because it is difficult to uniformly coagulate soymilk into a layer thicker than a predetermined thickness. Therefore, in order to achieve mass production, it is necessary to increase the size of the coagulation tank, and the length of the tank also becomes longer.

In the present invention, a tofu mat of a desired shape that has been coagulated with a thicker coagulation thickness than the conventional method is simply cut in hot water during transfer from the coagulation tank to the cutting process so that the tofu thickness after cutting becomes the desired thickness. The purpose is to use a mechanism to ensure that the vehicle rolls over.

[Means to solve the problem]

The present invention has been made in order to achieve the above-mentioned object, and the soybean milk put into one end of a trough-shaped coagulation tank that can be coagulated in a thicker layer than the conventional coagulation tank is protruded from an endless chain. At the same time, a conveyor is provided to transfer the tofu mat to the terminal end of the coagulation device which coagulates the soybean milk while transferring it along the longitudinal direction of the coagulation tank, and conveys it to the cutting process in hot water. The gist is that above the conveyor, a rollover piece that contacts the front surface of the upper part of the tofu mat being transferred and conveyed on the conveyor and rolls over the tofu mat is suspended and supported so as to be swingable in the direction of movement of the tofu mat. do.

[Function] The tofu mat in the desired shape that has been coagulated into a thick layer is transferred from the coagulation device onto the bar conveyor, and the front upper part of the tofu mat, which is conveyed through hot water to the cutting process, swings upward in the middle of this conveyor. When it comes into contact with the overturned piece that is suspended, it encounters resistance from the tofu mat when it swings in the direction of movement of the tofu mat, which causes a difference in transport speed between the lower and upper sides of the tofu mat. This ensures that the tofu mat is overturned backward in the direction of travel. Since this rolling process is carried out in hot water, even soft and fragile tofu can be reliably processed without damaging it.
It can be rolled over with a simple mechanism.

〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The tofu mat overturning device of the present invention will be described below based on an embodiment shown in the drawings.

In the figure, A is an automatic coagulation device for soybean milk, which consists of a trough-shaped coagulation tank L and an endless chain movably disposed along the length of the coagulation tank, with a large number of conveyors protruding at predetermined intervals. It is composed of a plate 2. This coagulation tank 1 is deeper than the conventional automatic coagulation tank, and even thick layer of soybean milk can be reliably coagulated. The temperature of the soybean milk charged into the coagulation tank is set to a high temperature of around 90 degrees Celsius, and the soybean milk is kept warm or heated so as to maintain the temperature at the initial stage of charging even when the soybean milk is transferred through the coagulation tank. Furthermore, the entire coagulation tank and the space inside the coagulation tank are heated so that the soymilk put into the coagulation tank is heated not only to the outer layer of the soymilk layer but also to the inner layer to a temperature suitable for coagulation. You can also do that. In this case, the material and temperature of the transfer plate are selected so that the soybean milk does not stick even when it solidifies. This transfer plate is generally made of a material specified by laws and regulations such as the Food Sanitation Act.

In this way, the soymilk introduced from one end of the trough-shaped coagulation tank is coagulated while being transferred into the tank by the movement of the transfer plate, and a thick layer of regular-shaped tofu, i.e., tofu mat T, partitioned by each transfer plate is formed using cypress wood. It is released into the water tank 3 from the terminal side. This tank 3
The interior is filled up to a predetermined line with hot water that maintains a sterilizing temperature, so the tofu mats released from the coagulation device remain in the hot water.

A conveyor 4, such as a bar conveyor, is disposed within this water tank 3, and the tofu mat T sent into the water tank is reliably transferred onto this conveyor 4. This conveyor 4
is a means for transporting tofu mats, which connects the coagulation device A and the next cutting process (not shown), and has a predetermined length and a width to ensure that the tofu mats are transported one by one. is driven at the same speed or faster than the transfer speed of the transfer plate in the solidification process.

Further, a rollover piece 5 is suspended above the conveyor 4 at an arbitrary position, and when the tofu mat transferred onto the conveyor is transferred, the rollover piece is arranged so that the upper front surface of the tofu mat comes into contact with the rollover piece 5. At least the height position of the lower end of the tofu mat is determined, and the rolling piece is suspended and pivoted to the frame so as to be able to swing in the direction of movement of the tofu mat. Alternatively, it is configured to automatically return to its original vertical position using spring pressure or other means. The rolling piece 5 may be plate-shaped, bar-shaped, or otherwise shaped so that it does not damage the tofu even if it comes into contact with the tofu mat.

When the upper part of the front side of the tofu mat being conveyed in the hot water comes into contact with this overturned piece 5, the lower part of the tofu mat moves at the same speed as the conveyor, but the upper side causes a load because it swings this overturned piece. , Only this overturning piece rocking load slows down the transfer speed of the upper part of the tofu mat. As a result, due to the continuous movement of the conveyor, a difference in transport speed occurs between the lower part and the upper part of the tofu mat, so that the upper part of the tofu mat is transferred to the rear side, that is, the tofu mat is rolled over. Due to this rollover, the lower edge of the tofu mat no longer comes into contact with the tofu mat, so that the tofu mat returns from the forward tilted state to the vertical state by the conveyor and waits for the next tofu mat to be transferred. In this way, the tofu mats are automatically and reliably overturned one after another.

Note that the water tank 3 can also be used by filling it with water instead of hot water.

〔Effect of the invention〕

According to the present invention, even when a tofu mat that has been solidified into a thick layer in the coagulation process is transported through hot water, it can be rolled over reliably and without damaging the tofu by simply contacting the rollover piece provided above during transport. Moreover, it has the advantage that the device is extremely simple and maintenance is easy.
