Problems solved by technology

[0005] 2. Crushed inline
[0007] At present, my country mainly adopts the first landfill method to deal with kitchen waste. The main problems are that it occupies land, wastes resources, and produces too much leachate, which causes serious secondary pollution.
The second method is to use the kitchen waste processor to crush the waste and discharge it directly into the sewer. The problem is that it is easy to block the water pipe and increase the load of the sewage treatment plant.
The main problem of the third method is that there are too many impurities in the garbage, which cannot be decomposed by composting, which affects the quality of composti...

Embodiment Construction

[0038] Treat 50 tons of kitchen waste, its main components are: moisture accounts for about 79%, crude fat accounts for about 29.9%, crude protein accounts for about 20%, crude fiber accounts for 3.53%, crude ash content accounts for 8.51%, and calcium accounts for 0.81%. Phosphorus 0.77%, pH 6.5.

[0039] Preparation:

[0040] 1. Solid-liquid separation: use the filtration method to separate the solid-liquid from the kitchen waste, and separate the liquid components from the solid components in the kitchen waste to obtain liquid materials and solid materials.

[0041] 2. Steam heating and degreasing: the solid material after solid-liquid separation enters the steam heating device, and is heated and degreased with high-temperature steam. The steam heating condition is to use steam at 110-120°C, heat for 10-30 minutes, and then spray with 80-100°C hot water for 5-10 minutes after the oil is completely liquefied, to wash away the liquefied oil in the material, grease and spray ...

Abstract

The invention is concerned with the integration disposal technics, it is: the food rubbish is the material, uses steam to process heat, remove oil, antisepsis, microbe solid - liquid zymolysis, distills oil separately, the solid component in rubbish transforms into biology active albumen feed by conduce animalcule multi-bacterium solid zymolysis, the liquid component transforms into liquid biology bacterium fertilizer by two times zymolysis. The invention can solve the problem of food rubbish, provide the lipid material, the biology feed and bacterium fertilizer for agriculture and industry.

Description

technical field [0001] The invention relates to a new process technology that uses kitchen waste as raw material, adopts steam heating to degreasing and disinfection, microbial solid-liquid fermentation and other comprehensive treatment techniques, separates and extracts oil, and converts solid components in waste through solid fermentation of beneficial microorganisms and multi-bacteria species It is a production process in which the liquid component is transformed into a liquid biological bacterial fertilizer through a secondary fermentation process into a biologically active protein feed. Background technique [0002] In the present invention, "kitchen waste" refers to food processing leftovers (kitchen waste) and edible residues (swill) produced by families, schools, canteens, and catering industries. Its composition is complex, which is a mixture of oil, water, fruit peel, vegetables, rice noodles, fish, meat, bones, waste tableware, plastic, paper towels and other subs...
