[0030] The working principle of the utility model:

[0031] Pour the food together with the solvent into the inside of the crushing cylinder 11. Activate the driving motor 12 to drive the blade 14 to rotate, so that the blade 14 crushes the food. The solvent can extract the food additives in the food. After the food is completely crushed, stop the operation of the driving motor 12. Control the first electric push rod 5 to extend, so that the first electric push rod 5 drives the rack 7 to move upward. By means of the meshing of the rack 7 and the gear 9, the crushing cylinder 11 can be driven to rotate counterclockwise, so that the crushing cylinder 11 rotates to the left. The mixed sample inside the crushing cylinder 11 can flow into the funnel 16. After converging through the funnel 16, it can be led out along the bottom of the funnel 16 and enter the suction filtration device to complete the removal of particulate matter in the sample, thus completing the preparation of the sample;

[0032] When the mixed sample inside the crushing cylinder 11 is basically led out, activate the first electric push rod 5 to contract, drive the rack 7 to move downward. By means of the meshing of the rack 7 and the gear 9, the crushing cylinder 11 can be driven to rotate clockwise, so that the crushing cylinder 11 rotates to the right. Activate the pump 26 and the second electric push rod 19 to operate. The second electric push rod 19 drives the spray head 23 into the inside of the crushing cylinder 11. The pump 26 transports the cleaning liquid to the spray head 23, so that the cleaning liquid sprays out along the spray head 23 to wash the inside of the crushing cylinder 11, so that the residues attached to the inner wall of the crushing cylinder 11 can flow out together with the cleaning liquid. Until the inside of the crushing cylinder 11 is cleaned, stop the operation of the pump 26, and make the second electric push rod 19 drive the spray head 23 to leave the crushing cylinder 11. The waste liquid generated by cleaning the crushing cylinder 11 can flow into the waste liquid collection box 17 for centralized collection. Replace the new funnel 16, and then the next round of food additive sample preparation work can be carried out.
