Description

DETAILED DESCRIPTION OF THE INVENTION (1) Industrial Field of Application The present invention relates to a soybean milk production apparatus for grinding soybean which is a raw material when producing soybean milk.

(2) Conventional Technique As a conventional means for grinding soybeans, there is a “continuous closed-type production method of soybean paste for soybean milk” (Japanese Patent Laid-Open No. 50-53552). In this method, a hopper is connected to the suction port of a crusher having a conical mill and an axial flow pump, water and soybeans are supplied to the crusher through the hopper, and the crusher is crushed into a paste. It is configured to be sent to the process.

(3) Problems to be Solved by the Invention In the above-mentioned conventional means, since the hopper is simply provided at the suction port of the crusher, that is, the grinder, the ratio of soybeans in the mixing ratio of soybeans and grinding water is comparative. When the amount of the soybeans is too low, the two are equally sucked, but when the proportion of soybeans is increased to make hard tofu, only the grinding water is sucked by the grinder and the thick soymilk cannot be made.

In view of such a current situation, the inventors of the present application have earnestly studied, and as a result, if the pump is provided between the hopper and the grinding device of soybean and ground water, the above-mentioned drawbacks can be solved. The present invention has been completed based on the finding that both of them can always be supplied to the grinder at a predetermined mixing ratio even when the amount of is large.

That is, the present invention is directed to a raw material hopper, a grinding water supply pipe communicating with the raw material hopper, a soymilk raw material transport pump, and a pipe-shaped casing, a grinding stator which is internally provided in the casing and has a protruding member on the inner peripheral surface, and an outer peripheral surface. A raw material hopper and a soy milk raw material transport pump, and a pump for feeding the soy milk raw material, and a pump for crushing the soybean milk. The soybean milk manufacturing apparatus is characterized in that the grinding machine and the grinding apparatus are connected to each other.

(4) Specific means for solving the problems In FIG. 1, 1 is a soybean hopper that stores soybeans, and 2
Is a screw conveyor and has a function of discharging soybeans from the soybean hopper 1.

A raw material hopper 3 stores soybeans supplied by the screw conveyor 2, and a grinding water supply pipe 4 is installed in the raw material hopper 3. The raw material hopper 3 always grinds at a constant ratio. Water and soybeans will be stored.

A regular means such as controlling the motor 8 of the screw conveyor 2 with the signal of the impact flow meter 7 for soybeans can be used for the constant supply of the grinding water with the flow meter 5 and the control valve 6 as shown in FIG. . Although not shown in the figure, it goes without saying that the soybeans or the ground water is configured so as not to overflow from the raw material hopper 3 by controlling the level. Here, a mixture of ground water and soybean is referred to as soymilk raw material.

9 is a raw material transfer pump for transferring the soy milk raw material, and its suction port
Reference numeral 10 communicates with the raw material discharge port 11 of the raw material hopper 3.
It is desirable that the raw material transfer pump 9 stably and quantitatively transfers the soy milk raw material, and a constant volume type pump such as a rotary pump is preferable.

12 is a soy milk raw material grinding device, mainly a pipe-shaped casing
13, a suction member 14 on the upstream side, a grinding member 15 on the downstream side, and a drive shaft 16 to which the suction member 14 and the grinding member 15 are attached and which is inserted into the center of the casing 13, The suction port 17 communicates with the suction member 14 in the axial direction,
In addition, discharge ports 18 are provided so as to communicate with the grinding member 15 in the radial direction, and the suction ports 17 are provided at the suction port 17 of the raw material transfer pump 9.
Is communicated with the discharge port 19 of.

The suction member 14 is composed of an impeller such as an axial flow pump or a centrifugal pump. On the other hand, the grinding member 15 has a protruding member on the inner peripheral surface.
A pipe-shaped grinding stator 21 having 20 and a projection member 22 corresponding to the projection member 20 on the outer peripheral surface are fitted and installed on the grinding stator 21, and are rotatably supported by a bearing 23. It consists of a grinding rotor 24. A gap 25 exists between the grinding stator 21 and the grinding rotor 24, and soybean milk raw material is ground into soybean milk when passing through the gap 25 due to the relative movement of these members 21 and 24. Reference numeral 20 is a motor for rotating the grinding rotor 24 via the phrase coaxial 16.

37 is a sealing device, and a mechanical seal is generally used.

Further, as the shape of the projecting members 20 and 22, other blade-like ones, hemispherical ones and the like can be mentioned.

A homomix line mill manufactured by Tokushu Kika Kogyo Co., Ltd. can be suitably used as the grinding device.

Reference numeral 28 denotes a raw material transfer amount control device, which is a raw material transfer pump 9, a load cell 29 installed below the pump 9 for detecting the transfer amount of the soymilk raw material, and the discharge of the raw material transfer pump 5 in response to a signal from the load cell 29. The controller 30 controls the amount of the soybean milk. The controller 30 changes the number of revolutions of the raw material transfer pump 9 in response to a signal from the load cell 29, so that the soymilk raw material is quantitatively transferred.

In order to ensure the accuracy of the load cell 29, the pipes 31 and 32 connected to the suction port 10 and the discharge port 19 are flexible pipes.

33 is a discharge pressure control device of the grinding device 12, a pressure sensor 34 installed in the suction port 17 of the device 12, a controller 35 to which the signal of the sensor 34 is sent, installed in the discharge port 18 of the grinding device 12 Pressure control valve controlled by controller 35
36, and has a function of keeping the pressure of the suction port 17 of the grinding device 12 at a positive pressure. Alternatively, a relief valve may be used as the discharge pressure control device 33.

The present invention is configured as described above, and the soybean stored in the soybean hopper 1 is supplied to the raw material hopper 3 by the screw conveyor 2. Further, a specified amount of grinding water is supplied to the raw material hopper 3 through the grinding water supply pipe 4, so that the raw material hopper 3 contains soymilk raw material at a predetermined ratio.

Next, the soybean milk raw material is crushed by the raw material transfer pump 9
Then, the soybean milk raw material is quantitatively transferred by the action of the raw material transfer control device 28, and the soybean milk raw material is sucked and ground by the suction member 14 and the grinding member 15 to become soymilk, which is used as it is or used as a raw material for tofu.

In the embodiment of FIG. 1, an example in which the grinding device 12 is provided with the suction member 14 has been described, but even if the grinding device 12 is not provided, it can be carried out by increasing the pressure of the raw material transfer pump 9. .

(5) Effect of the Invention The invention of the present application is configured as described above, and it is possible to supply the soymilk raw material having a predetermined mixing ratio to the grinding device regardless of the amount of soybean in the soymilk raw material.
