The water supply unit 100 is configured to supply water to the reservoir 200 and is connected to the water supply. A solenoid valve may be used as the water supply valve 120 , and a non-return valve for preventing backflow of water may be attached to the water supply line. A plate check valve may be used as the non-return valve. In addition, the non-return valve may be disposed between the water supply valve 120 and the water reservoir 200 .

A water supply line for supplying water is connected to the reservoir 200 .

When the pump 110 operates and the water supply valve 120 is opened, water is supplied to the reservoir 200 . In this case, it is preferable to use purified water as the water.

A heater rod 210 is provided at the lower end of the reservoir 200 to heat the water in the reservoir 200 to form steam.

In addition, the water reservoir 200 may be installed on a water level sensing rod. In order for steam to be formed in the reservoir 200 , the reservoir 200 should not be filled with water and a certain partial space should remain. Therefore, when a water level is reached by installing a water level sensing rod, the operation of the pump 110 may be stopped so that water is no longer supplied, and the water supply valve 120 may be closed.

The water level detection rod 220 may include a low water level detection rod 221 , a medium water level detection rod 222 , and a high water level detection rod 223 .

The water level sensing rods are rods having different lengths and may be attached to the upper portion of the water reservoir 200 . The low water level sensing rod 221 is the longest, and the high water level sensing rod 223 is the shortest.

In addition, a lamp can be attached to the control panel to make the lamp flash when the water level is low.

In the reservoir 200 , the amount of water may be adjusted between a medium water level and a high water level. When the water level falls below the intermediate water level, the pump 110 is operated, the water supply valve 120 is opened to supply water to the reservoir 200, and when the water level reaches the high water level, the pump 110 is stopped and the water supply valve 120 is opened. ) can be closed so that water is no longer supplied to the reservoir 200 . Even when the water pump 110 does not operate in the medium water level, when the water reaches the low water level because the water is not supplied, the lamp lights up so that the manager can check and take appropriate measures.

When the water goes below the medium water level, the amount of water is small, so steam generation is not easy.

A steam supply line is connected between the water reservoir 200 and the boiling pot 400 to supply steam to the boiling pot 400 .

In the boiling pot 400, beans ground through a grinder (not shown) are mixed with water (hereinafter referred to as soybean water) and input.

The grinder consists of a hopper and a grinding unit, and when beans and water are put into the hopper, they are crushed in the grinding unit and separated into okara and soybean water, and the soybean water is put into the boiling pot 400 .

In order to manufacture tofu, the bean water in the boiling pot 400 must be heated for a certain period of time. At this time, the bean water must be stirred to prevent sticking. However, this is a very cumbersome task. In the present invention, it is possible to solve this problem by allowing the bean water to circulate by itself.

In the reservoir 200 , a discharge valve 230 and an outlet for discharging water after completion of work may be formed at the lower end of the reservoir 200 .

The steam supply valve 320 may be a solenoid valve.

When the pressure in the reservoir 200 reaches a certain pressure, the pressure gauge 310 detects it, and at this time, the steam supply valve 320 is opened to discharge steam. The reference pressure can be set to about 6 bar. If the reference pressure is too high, the reservoir 200 may be damaged, and if the pressure is too low, it may be difficult to form a vortex even if the steam is sprayed because the pressure is too low.

The steam supply unit 300 may further include a pressure switch 330 , a safety valve 340 , a steam control valve 350 , and a non-return valve 360 .

The pressure gauge 310 and the pressure switch are installed adjacent to the reservoir 200 , and the steam supply valve 320 can be adjusted according to the control pressure of the pressure gauge 310 and the pressure switch 330 .

The pressure gauge 310 and the pressure switch are installed adjacent to the reservoir 200 , and the steam supply valve 320 can be adjusted according to the control pressure of the pressure gauge 310 and the pressure switch 330 .

When water flows into the reservoir 200 and passes the low water level, it is detected by the low water level detection rod and the low water level lamp is turned off. When the high water level is reached after passing the medium water level, the high level detection rod detects it, the pump 110 is automatically stopped, and water is no longer introduced into the reservoir 200 .

When the water in the reservoir 200 is heated by the heater rod 210 , the water is converted into steam to increase the pressure in the reservoir 200 . When the pressure in the reservoir 200 reaches a predetermined reference value (eg, 6 bar), the heater rod 210 is automatically turned off.

At this time, the steam supply valve 320 is opened and steam is supplied into the boiling pot 400 to heat the bean water. When the temperature of the excited boiling pot 400 reaches a constant temperature (for example, 95 degrees), a buzzer sounds to notify that the operation is complete.

As the steam exits, the water level goes down and becomes the medium water level, the water level is sensed by the medium water level detection rod and the pump 110 is operated again.

Operations of the pump 110 , the steam supply valve 320 , the water supply valve 120 , the heater rod 210 , etc. are controlled by the controller.

By the above operation, steam can be supplied into the boiling pot 400 while maintaining the water level and pressure in the reservoir 200 constant, the injection unit 520 is formed in a circular shape, and the injection port 522 is formed. By forming on the side and bottom, it is possible to form a vortex.
