Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a two-stage centrifugal separator for producing tofu.

Conventional technology Conventionally, a centrifugal separator for separating soybean milk and fresh snowflakes has been used to immerse soybeans in water, hydrate them, drain the water, and then
While adding water, put it in a grinder and grind it to make raw ``Go''.
was produced, and the raw material was squeezed using a single-stage squeezing machine at a speed of about 1,500 revolutions per minute.

Problems that the invention aims to solve This invention was developed for the purpose of a two-stage centrifugal separator that can continuously extract soymilk down to the last drop from grinding and crushing beans and boiling them in a boiling pot. .

Means for Solving the Problems The present invention is a means adopted to achieve the above-mentioned object, in which large and small drive wheels 4 and 5 are fixed to the drive shaft 3 of the motor 2 provided on the machine base 1. , the pulleys 6 and 7 are connected to an upper centrifuge 8 and a lower centrifuge 9.
Large and small driven wheels 1 fixed to each driven shaft 10, 11 of
2 and 13, the rotational speed of the basket 14 in the upper centrifugal separator 8 is set lower than the rotational speed of the basket 15 in the lower centrifugal separator 9, and the soybean milk is poured into the upper part of the upper centrifugal separator 8. The mouth 16 is opened, and a fresh snowflake discharge port 17 and a soybean milk extraction port 18 are provided at the lower part, and a fresh snowflake inlet 19 is opened at a position corresponding to the fresh snowflake discharge port 17 at the upper part of the lower centrifugal separator 9. At the bottom there is a fresh snowflakes outlet 2.
0 and a soy milk extraction port 21 are provided.

Function The present invention is constructed as described above, and the small drive wheel 4 fixed to the drive shaft 3 of the motor 2 provided on the machine base 1 is connected to the driven shaft 10 of the upper centrifuge 8 by means of the pulley 6. Wrap it around the fixed large driven wheel 12,
The basket 14 in the upper centrifuge is rotated at a relatively low speed of, for example, 250 revolutions per minute, and the beans (ground and boiled in a boiling pot) are fed through the input port 16 at the top.
Add soy milk (at a temperature of 90℃ or higher). In this case, since the basket 14 rotates at a relatively slow speed of 250 revolutions per minute, the soymilk put into the basket 14 does not splash out vigorously toward the many holes of the basket 14. The parts will not become clogged.

Then, the soymilk separated from the fresh snowflakes by centrifugal force through the numerous holes of the basket 14 is passed through the soymilk extraction port 18.
The raw snowflakes are extracted from the fresh snowflakes discharge port 17 and are continuously discharged to the fresh snowflakes input port 19 opened at a corresponding position of the lower centrifugal separator 9.

In addition, a large drive wheel 5 is fixed to a drive shaft 3 of a motor 2 provided on the machine base 1, and a small driven wheel 1 is fixed to a driven shaft 11 of a lower centrifugal separator 9 by a pulley 7.
3, the basket 15 in the lower centrifugal separator 9 is rotated at, for example, 1,200 revolutions per minute, and the soymilk separated from the fresh snowflakes by centrifugal force through the many holes in the basket 15 is again extracted from the soymilk extraction port 21. The extracted fresh snowflakes are discharged from a lower discharge port 20.

Embodiment An embodiment of the present invention will be explained in more detail based on the drawings. As shown in a side view of the present invention in FIG. 1 and a front view of the same in FIG. The large and small drive wheels 4 and 5 are fixed coaxially, and the pulleys 6 and 7 are connected to the large and small driven wheels 12 and 13 that are fixed to the respective driven shafts 10 and 11 of the upper centrifugal separator 8 and the lower centrifuge 9, respectively. The rotation speed of the basket 14 having a large number of holes in the upper centrifugal separator 8 was set at a relatively low rotation speed of 250 revolutions per minute. Also,
The rotation speed of the basket 15 having a large number of holes in the lower centrifugal separator 9 was set to 1200 revolutions per minute, which is higher than that of the basket 14. At the top of the upper centrifugal separator 8, there is a
℃ or above), open the soy milk inlet 16, and press the hinge 2.
According to 2, an upper door 23 is provided to enable inspection and cleaning of the inside, and a soy milk extraction port 18 is provided at the back of the basket 14, and a fresh acanthus discharge port 17 is provided at the lower front of the basket 14, and the lower centrifugal separation A fresh snowflake inlet 19 is opened at the top of the machine 9 at a position corresponding to the fresh snowflake discharge port 17, and a lower door 25 is provided with a hinge 24 to enable inspection and cleaning of the inside. Open the soy milk extraction port 21, and open the fresh snowflakes outlet 2 at the bottom of the front.
This is a configuration of a two-stage centrifugal separator for tofu production in which a zero is provided. In the embodiment, the rotation speed of the basket 14 in the upper centrifugal separator 8 was set to 250 per minute.
Although the rotation is described above, the present invention is not limited to this.
However, if the rotational speed of the basket 14 in the upper centrifugal separator 8 is set to a high rotation speed of 1200 rpm, which is the same as the rotational speed of the basket 15 in the lower centrifugal separator 9, the soymilk put into the basket 14 will be transferred to the basket 14.
It is desirable that the rotational speed of the basket 14 in the upper centrifugal separator 8 be around 250 revolutions per minute, since the particles are vigorously scattered toward the many holes in the tube and clog the holes.

Effects As a result of the present invention being configured as in the above-mentioned embodiment,
The following effects occur.

Conventionally, centrifugal separators that separate soybean milk and fresh snowflakes have been used to soak soybeans in water, hydrate them, drain them, and then
While adding water, put it in a grinder and grind it to make raw ``Go''.
The soybean milk was made by grinding the beans and boiling them in a boiling pot so that the beans could be extracted continuously down to the last drop. It was designed to run a 12-stage centrifuge, and it was also possible to operate two centrifuges at the same time with one motor.

In addition, the rotation speed of the basket with many holes in the upper centrifugal separator was set to low speed, and the rotation speed of the basket with many holes in the upper centrifuge was set to high speed, so that the soybean milk was put into the basket. Even when the basket in the upper centrifugal separator is rotated, soymilk can be prevented from scattering into the many holes of the basket and clogging the holes, and soybean milk can be efficiently recovered. Moreover, since the fresh acanthus squeezed by the upper centrifuge can be smoothly fed into the lower centrifuge, soybean milk can be efficiently recovered from the lower centrifuge as well, which is an excellent effect.
