[0029] The second ball nut is fixedly connected with an antifoaming plate 22. The antifoaming plate 22 is arranged between the filter plate 8 and the second partition plate 23. A plurality of inclined holes are evenly formed in the antifoaming plate 22. The antifoaming plate 22 is attached to the inner wall of the box body 1.

[0031] Furthermore, one end of the first reciprocating screw 9 is fixedly installed with a first conical wheel 12. One end of the second reciprocating screw 11 is fixedly installed with a fourth conical wheel 20. Both the first conical wheel 12 and the fourth conical wheel 20 are arranged outside the box body 1. A protective box 3 is fixedly installed on the side wall of the box body 1 corresponding to the positions of the first conical wheel 12 and the fourth conical wheel 20. A support plate 14 is fixedly installed on the side wall of the box body 1. A shaft rod 15 is rotatably installed on the support plate 14.

A second discharge port 17 is formed in the middle position of the upper end surface of the second partition plate 23, and an electromagnetic valve is installed at the second discharge port 17.

[0033] To facilitate the outflow of the slurry, an inclined plate 16 is fixedly installed on the inner bottom surface of the box body 1.

[0034] To further defoam the slurry, an ultrasonic rod 26 is installed on the inner bottom surface of the ultrasonic defoaming box 5, and a water pump 24 is fixedly installed at the top end inside the ultrasonic defoaming box 5.

[0035] Working principle:

[0036] During use, the pea protein slurry is poured into the box body 1 from the feed pipe 2. The pea protein slurry reaches the upper surface of the filter plate 8 through the first discharge port 7, and then the pea protein slurry reaches the upper surface of the second partition plate 23 through the filter holes on the filter plate 8. At this time, the solenoid valve at the second discharge port 17 is in a closed state; among them, the filter plate 8 filters the pea protein slurry, filtering out the filter residues in the pea protein slurry and also being able to filter out some foam.

[0037] Start the motor 4. The output end of the motor 4 drives the second reciprocating lead screw 11 to rotate. When the second reciprocating lead screw 11 rotates, it drives the defoaming plate 22 to reciprocate in the box body 1. When the defoaming plate 22 reciprocates, the inclined holes on the defoaming plate 22 can play a role in guiding and stirring the pea protein slurry on the other side of the defoaming plate 22, and at the same time can also push the foam above the pea protein slurry to one side. The design of the inclined holes enables the liquid to flow upward through the inclined holes when the defoaming plate moves to the right, and when the defoaming plate moves to the left, the liquid can flow downward through the inclined holes, thereby better eliminating the foam of the pea protein slurry. When the defoaming plate 22 slides to the end of the thread on one side of the second reciprocating lead screw 11, the defoaming plate 22 just fits against the inner wall of the box body 1. When the defoaming plate 22 fits against the inner wall of the box body 1, it can squeeze the foam floating on the liquid surface to make it burst, thus more effectively eliminating the foam of the pea protein slurry.

[0038] At the same time, the motor 4 drives the second reciprocating lead screw 11 to rotate. The rotation of the second reciprocating lead screw 11 drives the fourth conical wheel 20 to rotate. The rotation of the fourth conical wheel 20 drives the third conical wheel 19 meshing with it to rotate. The third conical wheel 19 drives the second conical wheel 13 to rotate through the shaft rod 15. The rotation of the second conical wheel 13 drives the first conical wheel 12 meshing with it to rotate. The rotation of the first conical wheel 12 drives the first reciprocating lead screw 9 to rotate. When the first reciprocating lead screw 9 rotates, the scraper 10 reciprocates above the filter plate 8, and then pushes the residues filtered out above the filter holes on the filter plate 8 to the edge, preventing the residues from accumulating too much and blocking the filter holes, resulting in the problem of slow liquid flow.

[0039] Finally, open the solenoid valve at the second discharging port 17, so that the pea protein slurry in the cavity 1 of the box body 1 between the filter plate 8 and the second partition plate 23 flows into the space between the second partition plate 23 and the inclined plate 16 from the second discharging port 17. Under the action of the inclined plate 16, the pea protein slurry in the box body 1 finally flows into the ultrasonic defoaming tank 5 through the through hole 18. The ultrasonic defoaming tank 5 and the ultrasonic rod 26 are both prior arts and will not be elaborated here.

[0040] The pea protein slurry in the ultrasonic defoaming tank 5 is further defoamed by the ultrasonic rod 26. Start the water pump 24, and the water pump 24 pumps the defoamed slurry in the ultrasonic defoaming tank 5 out from the discharging port 6 through the water pipe 25.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present invention.
