[0026] When the device is in use, soybean meal is fed from the feed hopper, and the material enters the impregnation section under the conveyance of the spiral blades. Water is injected into the impregnation section to impregnate the soybean meal. With the continuous conveyance of the spiral blades, the material gradually fills the impregnation section, and the impregnated material is lifted by the lifting section to enter the refining section.

[0027] The refining section grinds the soybean meal, which then enters the dissolution storage tank under the action of the feed pump. Before entering the storage tank, it is mixed with the dissolution liquid sent from the dissolution liquid inlet. When in use, the multiple storage tanks are filled one by one through the control of the solenoid valve and transported to the rear one by one, so that the material can have a certain reaction time in the storage tank.

[0028] After the reaction, the impurities in the material are discharged after centrifugal separation in the centrifugal distribution part, and the solution enters the neutralization tank. Through the cooperation of the three-way valve and the solenoid valve of the neutralization tank, the material enters the neutralization tank from the bottom. There are also multiple neutralization tanks, which are used together to allow the material to have a certain neutralization time. When it is necessary to inject material into a certain tank, close the three-way valve and open the solenoid valve of the corresponding tank. The neutralization tank also needs to be injected with neutralizing liquid from the top through the neutralizing liquid inlet to neutralize it.

[0029] The neutralized material forms layers in the storage tank. At this time, the solenoid valve and the three-way valve can be opened to introduce the protein slurry at the bottom into the drying section for drying. After the protein slurry is completely immersed in the drying section, the flow direction of the three-way valve is adjusted to discharge the remaining supernatant in the storage tank through the discharge end.
