[0036] Embodiment 2

[0037] See also Figures 1 to 7The present invention provides a technical solution: a method for using a pulverizing device for producing food additives, comprising the following steps:

[0038] Step 1: Pour the raw material into the crushing chamber 3 through the feed hopper 5, and then the output end of the first servo motor 8 drives the crushing roller 4 to rotate, so that the two crushing rollers 4 rotate to crush the raw material, and the crushed raw material falls into the space between the two partitions 16 in the processing cylinder 14 through the bottom groove 10 and the first elastic tube 11.

The unqualified raw materials remain in the processing cylinder 14. When the output end of the third servo motor 19 drives the rotating column 15 to continue to rotate, the unqualified raw materials between the two partitions 16 move to the top of the discharge trough 18, so that the unqualified raw materials fall into the third elastic tube 22 through the discharge trough 18, and then fall into the conduit 23 through the third elastic tube 22, and then fall into the conveyor 24 through the conduit 23;

8. A pulverizing device for producing food additives according to claim 1, characterized in that: The method for using the pulverizing device for producing food additives comprises the following steps: Step 1: Pour the raw material into the crushing chamber (3) through the feed hopper (5), and then the output end of the first servo motor (8) drives the crushing roller (4) to rotate, so that the two crushing rollers (4) rotate to crush the raw material, and the crushed raw material falls into the space between the two partitions (16) inside the processing cylinder (14) through the bottom groove (10) and the first elastic tube (11), and at the same time, the output end of the second servo motor (9) drives the cleaning roller (7) to rotate, so that the cleaning roller (7) cleans the raw material on the surface of the crushing roller (4); Step 2: After receiving the raw materials for a certain period of time, the output end of the third servo motor (19) drives the rotating column (15) to rotate, so that the rotating column (15) drives the partition (16) to rotate, so that the raw materials between the two partitions (16) move to the top of the filter hole (17), and then use the space between the other two partitions (16) to receive the materials. The qualified raw materials leak through the filter hole (17) into the second elastic tube (20), and then can be discharged through the switch valve (21) to the bottom of the switch valve (21) for storage. The unqualified raw materials are placed in the receiving container, and the unqualified raw materials remain in the processing cylinder (14). When the output end of the third servo motor (19) drives the rotating column (15) to continue to rotate, the unqualified raw materials between the two partitions (16) move to the top of the discharge chute (18), so that the unqualified raw materials fall into the third elastic tube (22) through the discharge chute (18), then fall into the conduit (23) through the third elastic tube (22), and then fall into the conveyor (24) through the conduit (23); Step 3: The output end of the fifth servo motor (25) drives the spiral feed shaft (26) to rotate, so that the spiral feed shaft (26) pushes the raw materials inside the conveyor (24) through the discharge pipe (43) into the feed hopper (5), and the raw materials are continuously crushed by the two crushing rollers (4); Step 4: While the output end of the fifth servo motor (25) drives the spiral feed shaft (26) to rotate, the spiral feed shaft (26) drives the second connecting shaft (40) to rotate through the second belt pulley (42), so that the second connecting shaft (40) drives the transmission rod (38) to rotate through the second bevel gear (41), so that the transmission rod (38) drives the worm wheel (37) to rotate through the worm section (39), so that the worm wheel (37) drives the first bevel gear (36) to drive the second rotating shaft (34) to rotate through the first connecting shaft (35), so that the second rotating shaft (34) drives the first rotating shaft (34) to rotate through the first belt pulley (32). The first rotating shaft (27) rotates so that the first rotating shaft (27) drives the cam (28) to rotate. When the convex end of the cam (28) rotates toward the moving block (31), the moving block (31) pushes the moving column (29) to drive the processing cylinder (14) to move upward. When the round end of the cam (28) rotates toward the moving block (31), the connecting spring (30) pushes the moving block (31) and the moving column (29) to move downward, so that the two moving columns (29) drive the processing cylinder (14) to move downward, causing the processing cylinder (14) to vibrate, and causing the raw materials inside the processing cylinder (14) to vibrate, so as to improve the screening efficiency of the raw materials inside the processing cylinder (14).
