During the rotation, the juice on the food residue can be thrown to the outer sleeve 501 through the filter paper 506 and the through hole 504. The juice enters the tank body of the juice tank positioning ring 524 through the liquid unloading cylinder 508. When the residue in the inner sleeve 503 needs to be cleaned, the power output shaft on the servo motor 301 rotates counterclockwise to drive the rotating shaft 302 to rotate counterclockwise. At this time, the outer gear plate 311 can be rotated, and the rotation of the outer gear plate 311 drives the connecting gear 514 to rotate. The rotation of the connecting gear 514 drives the reciprocating screw rod 513 to rotate six circles. At this time, the connecting rod 512, the inner connecting column 510 and the outer plug 511 Moves from the highest point to the lowest point, at this time the external plug 511 does not block the funnel 505, so that the residue can fall downward through the funnel 505, and the residue falls into the tank body on the residue tank positioning ring 525 through the discharge barrel 515, and the external gear disk 311 continues to rotate to drive the connecting gear 514 to rotate, and the rotation of the connecting gear 514 drives the reciprocating screw rod 513 to rotate six circles. At this time, the connecting rod 512, the internal connecting column 510 and the external plug 511 move from the lowest point to the highest point, and at this time the external plug 511 blocks the funnel 505.

A multi-channel filtering device for food inspection according to claim 4, characterized in that: A support plate (523) is provided at the bottom of the discharge barrel (515), a juice tank positioning ring (524) is fixedly mounted on the top of the support plate (523), and a residue tank positioning ring (525) is provided on the right side of the juice tank positioning ring (524).

7. A multi-channel filtering device for food inspection according to claim 6, characterized in that: The outer edge of the support plate (523) is fixedly equipped with a limiting column (522), the outer edge of the support plate (523) is slidably connected to the limiting bracket (520), and the outer wall of the limiting bracket (520) is provided with a limiting groove (521).

8. A multi-channel filtering device for food inspection according to claim 7, characterized in that: The bottom of the support plate (523) is fixedly equipped with a top fixing column (526), ​​the bottom of the top fixing column (526) is provided with a bottom fixing column (527), the bottom fixing column (527) is installed on the rotating tray (4), and the outer edges of the top fixing column (526) and the bottom fixing column (527) are movably sleeved with a fixing spring (528).

9. A multi-channel filtering device for food inspection according to claim 1, characterized in that: The inner wall of the rotating tray (4) is fixedly sleeved on the outer rotating ring (308), the outer edge of the rotating shaft (302) is fixedly sleeved with a bearing (312), the outer wall of the bearing (312) is fixedly sleeved with a protective shell (313), the protective shell (313) is mounted on the rotating tray (4), and the bottom of the rotating block (303) is fixedly assembled with a limit plate (310).

10. A multi-channel filtration method for food inspection according to claim 9, characterized in that: The following steps are involved: Step 1: first, place the can body on the juice can positioning ring (524) and the residue can positioning ring (525), so that the can body on the juice can positioning ring (524) and the can body on the residue can positioning ring (525) correspond to the liquid discharge cylinder (508) and the material discharge cylinder (515) respectively; Step 2: Remove the top cover (529), place the filter paper (506) in the inner sleeve (503), place the crushed food in the inner sleeve (503), and then install the top cover (529) on the outer sleeve (501); Step 3: Start the servo motor (301) to drive the rotating shaft (302) to rotate clockwise, and the rotating shaft (302) drives the rotating block (303), the clamping block (307), the outer rotating ring (308) and the rotating tray (4) to rotate. At this time, the outer sleeve (501) and the inner sleeve (503) on the rotating tray (4) can be rotated. Under the action of centrifugal force, the juice enters the outer sleeve (501) through the filter paper (506) and the through hole (504). At this time, the juice enters the tank body on the juice tank positioning ring (524) through the liquid unloading cylinder (508); Step 4: The residue in the inner sleeve (503) is then processed. At this time, the servo motor (301) drives the rotating shaft (302) and the outer gear disc (311) to rotate counterclockwise. The rotation of the outer gear disc (311) drives the connecting gear (514) and the reciprocating screw (513) to rotate. The rotation of the reciprocating screw (513) drives the connecting rod (512), the inner connecting column (510) and the outer plug (511) to move downward, so that the funnel (505) is not blocked. At this time, the residue passes through the funnel (505) and the discharge barrel (515) into the tank body on the residue tank positioning ring (525); Step 5: Remove the tank body placed on the juice tank positioning ring (524) and the residue tank positioning ring (525).
