Thereby can reduce artificial output to need not take out the inside rubbish of garbage bin in advance, directly with the inside rubbish of garbage bin directly empty in that the hopper 36 is inside can. As long as gravity inductor 231 can sense the gravity of garbage bin, judge whether have rubbish in the garbage bin, in case there is rubbish just timely empting to reduce piling up of rubbish, reduce the peculiar smell.

S3, the garbage is crushed by the crushing blade 43 in the crushing box 41, and the crushed garbage enters the feeding cavity 511 of the press dehydration device 5. Rubbish is broken through broken case 41, can be convenient for rubbish post processing. The oil-water mixture is separated by the oil-water separation component 8, and the separated oil can be used for preparing biofuel for recycling. The spraying assembly 44 is then activated to flush the residual waste inside the crushing bin 41 into the feed chamber 511 of the press dewatering device 5. Wash the inside spare part of broken case 41 through shower nozzle 442, can reduce giving off of peculiar smell on the one hand, on the other hand can protect the inside spare part of broken case 41, but also can be to the more thorough of refuse treatment.

S4, conveying the garbage entering the feeding cavity 511 to the squeezing cavity 512 through the auger 52, squeezing water in the garbage through the squeezing cavity 512, discharging the squeezed water from the second water discharge pipe 55, finally disconnecting the plugging mechanism 54 from an outlet of the squeezing cavity 512, and discharging the dehydrated solid kitchen garbage through the discharging cavity 513. The solid waste can be used as fertilizer and feed after being treated, and the grease in the liquid waste can be used for preparing biofuel, so that the solid and the liquid in the waste are separated, and the kitchen waste can be fully utilized.

S5, conveying the solid kitchen waste discharged from the discharging chamber 513 to the inside of an aerobic fermentation system through a plate chain conveying belt and a third fixing plate 63, starting a stirring device and a heat preservation device in the fermentation bin to fully mix the kitchen waste and the strains, degrading the kitchen waste, and oxidizing and synthesizing the waste.
