The two-stage sorting process is the mainstream process of food waste pretreatment,which has the advantages of low impurity rate and large processing capacity.Optimizes and improves the existing secondary sorting system,the results show that the speed of the large substance sorter is proportional to the proportion of sorting material,and the optimal speed is 95 r/min and the screen aperture is 5 cm from the organic matter loss rate and slurry impurity rate.The spray device installed on the fine sorting machine can wash away the organic matter and grease on the fine sorting material,improve resource utilization and grease utilization.
