Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an apparatus for boiling "A", a fluid obtained by grinding soybeans, which is a raw material for foods such as tofu and soy milk.

[Conventional technology]

Conventionally, our boiling apparatus had a structure in which a screw blade was rotatably installed in a U-shaped gutter, and a long steam discharge pipe was disposed near the bottom of the gutter.
With this structure, I was put in from one end of the gutter, steam was released into me from the steam release pipe, and while I was gradually boiled with steam, the screw blade was rotated to send me to the other end of the gutter. The waste was continuously discharged downward from the gutter and sent to the next process. In addition, a steam jet pipe having a large number of steam jet holes is inserted into the axial center of a cylindrical pot body with both ends sealed, and boiling pots with spiral plates attached to the steam jet pipe are arranged in multiple stages in the vertical direction. ,
My boiling device, in which the supply port and outlet of the boiling pot are connected in series and the water is sent from the lower pot to the upper layer, is known from Japanese Patent Laid-Open No. 48-48673.

[Problem that the invention seeks to solve]

In our conventional boiling apparatus, much of the steam released from the steam discharge pipe was dissipated into the atmosphere, and the steam was not utilized effectively. Also, it is a fluid with low viscosity, close to a liquid, and moves through the gutter due to the difference in water head, so its movement speed and boiling time are determined by the rotational speed of the screw blade. The problem was that it was difficult to control and that it was impossible to achieve uniform and reproducible boiling. Furthermore, in the boiling device disclosed in Japanese Patent Application Laid-Open No. 48-48673, the steam from the steam outlet cannot be stored in the upper part of the boiling pot, but moves in the form of bubbles to the boiling pot above. . This bubble creates a pumping action that moves us upwards. Therefore, it was not possible to blow out a large amount of steam. In addition, since the foam only came into contact with us and passed through immediately, it was not possible to heat it uniformly and efficiently. The present invention provides a practical boiling device that solves these problems.

[Means for solving problems]

The gist of the present invention that solves this problem is that a small-diameter hole 4 is formed inside a horizontally placed closed cylindrical body 1.
A steam discharge pipe 5 having a large number of holes is rotatably attached coaxially thereto, a screw blade 3 is fixed to the outer circumferential surface of the steam discharge pipe 5, and the introduction pipe 6 and the other are attached to the cylindrical body 1 at a position above one end. A discharge pipe 7 is connected to the lower end of the cylindrical body 1, and a temporary storage chamber 2 is provided outside the cylindrical body 1, communicating with the atmosphere at the ceiling and connected to the discharge pipe 11 at the bottom. The temporary storage chamber 2 is arranged such that the height of the inner lower end of the outlet end of the temporary storage chamber 7 is approximately 2 cm lower than the height of the top of the internal space of the cylindrical body 1.
and the above-mentioned discharge pipe 7, and further the above-mentioned cylindrical body 1
Two or more cylindrical boiling sections A each having a steam pressure release port 8 at the top thereof are arranged vertically in multiple stages, and the discharge pipe of the temporary storage chamber 2 at the top is the final outlet of the boiling section. This boiling device is characterized by a tube.

[Effect]

In this invention, I continuously introduce steam into the closed cylindrical body 1 through the introduction pipe 6 to the extent that it is filled to a position of about 1 to 2 cm from the top of the internal space of the cylindrical body 1, and also the steam discharge pipe 5. The screw blade 3 is rotated at a predetermined rotational speed while sending steam into. I am moved at the feed speed of the screw blade 3 while being gradually boiled by the steam ejected from the hole 4 of the steam discharge pipe 5. Since the cylindrical body 1 is sealed, the steam inside the cylindrical body 1 participates in the boiling without dissipating into the atmosphere, and also acts to keep the temperature inside the cylindrical body 1 constant. The excess pressure of the steam is released from the steam pressure release port 8 to prevent the steam inside the cylinder 1 from becoming high pressure and to prevent the feed speed from increasing due to the steam pressure. The liquid that has been sent to the other end of the cylindrical body 1 is discharged from the discharge pipe 7 and flows into the temporary storage chamber 2 through the rising pipe. The steam sent along with me in the temporary storage room dissipates into the atmosphere. Moreover, since the temporary storage chamber 2 and the cylindrical body 1 are connected through the discharge pipe 7, the level of the cylindrical body 1 and the level of the temporary storage chamber 2 automatically become the same level. If the position of the communication port is too high, the fluidity of the fluid is so strong that the material cannot be lifted from the cylindrical body 1 to the communication port, and the material in the temporary storage chamber 2 decreases and becomes empty. If the position of the communication port is set low, the level of the temporary storage chamber 2 will be lowered, and a water head difference will occur between the level of the temporary storage chamber 2 and the level of the temporary storage chamber 2. It moves as if being sucked into it, and my feed speed tends to increase. Therefore, it is best to place the communication port at the same level as the cylindrical body 1 so that a fixed amount can be supplied most stably. The liquid in the temporary storage chamber 2 is discharged from the liquid discharge pipe located at the bottom of the temporary storage chamber 2. The pipe diameters of the temporary storage chamber 2, the first discharge pipe, and the second discharge pipe 7, and the rotational speed of the screw blade 3 are designed to be optimum diameters so as to enable a stable set feed rate. 9 in the figure is a communication port,
10 is an opening of the temporary storage chamber 2. In the embodiment shown in the drawings, the steam discharge pipe 5 serves as the rotation axis of the screw blade 3.

〔Effect of the invention〕

As described above, according to the present invention, by making the cylindrical body 1 a closed type, steam can be used effectively, the amount of steam used can be reduced, and energy can be saved, and the pressure of the steam ejected from the hole can be reduced. It is released from the steam pressure release port, and the pressure due to my water head inside the cylinder is temporarily cut off by the storage chamber, so that the steam pressure of the upper stage and my water head pressure do not act on the lower cylinder, and it is independent. This allows for uniform boiling using a large amount of steam within the cylindrical body. The speed of my movement is determined by the rotational speed of the screw blade, and since I can obtain a stable and constant feed speed, I can control the degree of boiling.
I was able to control the boiling speed accurately and was able to achieve uniform and reproducible boiling.
