The unloading cylinder 1 is used to provide a channel for kitchen waste to enter the conveying cylinder 2, and guide the kitchen waste into the conveying cylinder 2 to ensure the continuity and efficiency of the treatment. The unloading funnel 11 is used to store kitchen waste and guide the kitchen waste into the unloading cylinder 1 to prevent the kitchen waste from overflowing or spilling during the feeding process, and to ensure the neatness and orderliness of the unloading process. The conveying cylinder 2 is used to convey and squeeze the kitchen waste and separate the solid and liquid parts.
