Example Embodiment

[0030] The present invention will be described in further detail below in conjunction with the embodiments of the drawings.

[0031] The technical scheme of the present invention is realized as follows:

[0032] A method for treating household kitchen waste, using the following steps:

[0033] Crushing treatment: the food waste is crushed, and the crushing treatment is carried out by a garbage shredder to form fragments or powdered food waste;

[0034] Solid-liquid separation: Separate liquid and solid in food waste.

[0035] Stirring fermentation: Stirring and fermenting broken pieces or powdered food waste;

[0036] In the solid-liquid separation step, dehydration is first performed by screw extrusion, and then heated by a heating device and convection by a fan during the stirring and fermentation process to adjust the moisture content of the broken or powdered food waste to 30%-40%.

[0037] The process of stirring and fermentation is:

[0038] Preheating the fragments or powdered food ...

Abstract

The invention provides a domestic kitchen waste treatment method. The domestic kitchen waste treatment method is characterized by adopting the following steps of: pulverization treatment, namely pulverizing kitchen wastes to form fragmental or powdery kitchen wastes; solid and liquid separation, namely separating the liquid from the solid in the kitchen wastes; stirring and fermentation, namely stirring and fermenting the fragmental or powdery kitchen wastes; gas deodorization, namely deodorizing the gas generated in a fermentation process and exhausting the gas to air; and discharging and granulation, namely preparing small particles by using residues generated after the stirring and fermentation step is ended. According to the domestic kitchen waste treatment method provided by the invention, stirring is carried out in a fermentation process, so the fermentation efficiency is improved; the gas is oxidized and decomposed by using an ultraviolet sterilizing lamp and is purified and absorbed by aluminosilicate hydrate and active carbon so as to prevent generation of peculiar smells; a granulating device is used, so the recycle of the kitchen wastes is improved, and an environment protection effect is achieved.

Description

technical field [0001] The invention relates to a garbage treatment method, in particular to a household kitchen garbage treatment method. Background technique [0002] Food waste refers to food residues discarded during food processing and food residues after eating and drinking. Its components mainly include peel and bone, meal crumbs, insoluble protein, fiber and starchy insoluble organic matter. , whose composition is extremely complex depending on the meal. Since food waste is rich in nutrients, if it is discharged directly into the natural world without treatment, it will rot and deteriorate in a short period of time under the action of suitable temperature and bacteria, which will not only pollute the surrounding environment, breed mosquitoes and flies, but also invade a large number of wastes. land, but also cause a lot of waste of resources. [0003] When the existing food waste disposer processes the food waste, the food waste and the starter are not evenly mixed...
