Abstract

The invention relates to the technical field of kitchen waste treatment, and particularly relates to a kitchen waste treatment system. The following technical scheme is adopted in the invention: the kitchen waste treatment system comprises a receiving hopper, wherein a spiral conveying rotation machine is connected to the left side of the receiving hopper; a first sorting machine is arranged at the lower end of the left side of the spiral conveying rotation machine; a main discharge port is formed in the lower end of the first sorting machine; a crushing-slurrying machine is arranged at the position of the main discharge port in the lower end of the first sorting machine; a sand setting machine used for sand removal is connected to the crushing-slurrying machine; a moisture-heat heating kettle is arranged in a left-side area of the spiral conveying rotation machine; and materials subjected to the sand removal through the sand setting machine enter into the moisture-heat heating kettlethrough a centrifugal pump to be subjected to moisture-heat hydrolysis treatment. The kitchen waste treatment system has the following advantages: oil interface characteristics are optimized; efficient leaching, liquefying and floating for solid-phase internal oil in kitchen wastes are promoted; the waste oil separation characteristics of the kitchen wastes are improved; and through a centrifugal-gravitational double-effect special separation device, the waste oil recovery efficiency for the kitchen wastes is greatly increased.

Description

technical field

[0001] The invention relates to the technical field of kitchen waste treatment, in particular to a kitchen waste treatment system. Background technique

[0002] In developed countries in Europe and the United States, the amount of food waste generated is small. Most of them install a shredder in the kitchen to cut up the food waste and flush it into the municipal sewer network with water. The method is low in cost, occupies a small area, and is convenient to operate, but has no products, no resource recovery, and consumes water resources. At the end of the 20th century, Japan's Chuyuan Company and Singapore's Oradora Company used heat treatment methods to heat and dry organic waste to achieve feed. This process sterilizes more thoroughly, realizes the resource recovery of the nutrients in the garbage, and can recover part of the oil, but purely uses the heat source to dry the water, which consumes a lot of energy. South Korea's E.A.TECH company uses dehydra...

Embodiment Construction

[0029] Such as Figure 1 to Figure 5 As shown in the figure, a food waste treatment system, which will carry out wet heat hydrolysis of the food waste after removing impurities in a special humid-heat heating kettle, control the wet-heat reaction conditions, effectively kill pathogenic bacteria, remove peculiar smell, and make the macromolecules in the garbage Organic matter is hydrolyzed into small molecular organic matter that is easily digested and absorbed by plants and animals. After hydrolysis, the material is dried and sieved to be used as raw material for making insect feed and fertilizer. This treatment system changes the physical and chemical form of oil in kitchen waste and the way it combines with other components, optimizes the interface characteristics of oil, promotes the efficient leaching, liquefaction, and floating of oil in the solid phase of kitchen waste, and improves the separation characteristics of kitchen waste oil , Through the special centrifugal and...
