and 3, step 3: the driving motor (8) can also drive the material suction nozzle (11) to sweep on the circumference of the upper port of the can for sucking the food mixed liquid remained on the can;

and 4, step 4: the rotating inner cylindrical cover (5) can drive a plurality of knocking rods (23) to knock the outer wall of the can, so that food bubbles in the can are discharged out of the can;

and 5: the rotating inner cylindrical cover (5) can also drive the brush (19) to sweep at the upper end opening of the can, so as to sweep the food mixed liquid on the can into the material suction nozzle (11);

and 6: the inner cylindrical cover (5) is driven to be separated from the can through the telescopic equipment (3), and the detection and the cleaning of the can are automatically completed.
