Detailed Description

Example 1

As shown in FIG. 1, the automated bag breaking and sieving integrated system of the present invention comprises a conveying unit 10, a cutting unit 20 and a sieving unit 30. The conveying unit 10 is a belt feeder, the top of the belt feeder is connected with the cutting unit 20, and the bottom of the belt feeder is provided with a residual liquid collecting tank 11. The cutting unit 20 comprises a cutting cavity 21 and a cutting device 22, the cutting device 22 being located within the cutting cavity 21.
