[0002] As society continues to develop, people's living standards are also constantly improving. In daily life, people typically generate a lot of waste, among which food waste occupies a significant portion. Food waste refers to the waste generated in daily life, food processing, catering services, and institutional catering activities. It includes discarded vegetable leaves, leftover food, fruit peels, eggshells, tea dregs, bones, etc., and its main sources are family kitchens, restaurants, hotels, canteens, markets, and other industries related to food processing.
[0003] Food waste contains extremely high levels of moisture and organic matter, making it easily perishable and producing a foul odor. With proper treatment and processing, it can be transformed into new resources. Its high organic content allows it to be used as fertilizer or animal feed after rigorous processing. It can also produce biogas for fuel or power generation, while the oil and fat components can be used to produce biofuels.
[0004] Currently, the treatment of food waste usually requires separating the organic and inorganic materials. The organic materials are crushed and pulped, while the inorganic materials are treated separately. However, existing food waste treatment equipment is usually intermittent, which results in low treatment efficiency and high water content in the inorganic residue, typically around 80%. Summary of the Invention

[0013] As a further improvement, the height of the middle bottom of the slurry storage chamber is lower than that of the two end bottoms, and the slurry outlet is located on the side wall of the slurry storage chamber close to the middle bottom.
[0014] As a further improvement, the cross section of the slurry storage chamber is rectangular.
[0015] As a further improvement, the cross section of the horizontal cylinder is circular, the cross section of the filtrate hole plate is in the shape of a circular arc, and the filtrate hole plate is located below the blade, the feeding screw auger and the discharge blade.
[0016] As a further improvement, the rotating shaft extends out of the two ends of the horizontal cylinder and is connected to a bearing seat respectively, one end of the rotating shaft is connected to a belt pulley, and the belt pulley is connected to a driving motor through a belt drive.
[0017] As a further improvement, the driving motor is a variable frequency motor.

[0019] The kitchen waste slurry and residue separator provided by the application adopts a horizontal design, food waste materials enter the horizontal cylinder through the feeding port, and under the action of the feeding screw auger, the materials enter the blade area. With the rotation of the blade, the materials make rotational motion, and the organic matter in the materials is crushed and pulped by colliding with the blade. The inorganic matter in the materials reaches the discharge port position of the horizontal cylinder under the rotation of the blade, and the inorganic material residue is centrifuged and dewatered by the centrifugal force of the discharge blade and discharged through the discharge port. The slurry in the horizontal cylinder enters the slurry storage chamber through the filtrate hole plate and is discharged through the slurry outlet, so that the moisture content of the discharged inorganic material residue is low, and can be below 50%.
