[0058] After the crushing is completed, the sliding ring 38 is pushed downward to drive the connecting tube 49 to move downward, so that the piston rod 50 in the connecting tube 49 is disengaged from the first through hole 10, and the process continues until the connecting tube 49 corresponds to the second through hole 11, and the first motor 14 is started again to drive the sleeve rod 41 to rotate. The rotation of the sleeve rod 41 can drive the scraper 48 to rotate. During the rotation of the scraper 48, the meat paste can be pushed into the connecting tube 49 and discharged into the sampling tube 53 through the connecting tube 49 until the sampling tube 53 is filled with meat paste. Then the sampling tube 53 is pulled out from the socket 52, and the meat paste is added to the centrifuge tube for extraction to obtain the supernatant, and the supernatant is detected by the liquid chromatograph 60;

[0059] At the same time, the second motor 56 is started again to drive the second gear 57 to rotate. The rotation of the second gear 57 can drive the outer gear ring 54 to rotate. The rotation of the outer gear ring 54 can drive the rotating cylinder 43 to rotate. The rotation of the rotating cylinder 43 can drive the bottom plate 42 to move downward. When the bottom plate 42 moves to one side of the rectangular opening 44, the first motor 14 is started again to drive the scraper 48 to rotate, so as to discharge the remaining meat paste. At the same time, the water pump on one side of the water tank 2 is started. The water pump can pump the water in the water tank 2 and spray it through the annular nozzle 45 and the nozzle 46 to clean the crushing barrel 7 and the rotating cylinder 43.
