Kitchen waste recycling automatic treating all-in-one machine and treatment process thereof

Abstract

The invention relates to a kitchen waste recycling automatic treating all-in-one machine and a treatment process thereof. The all-in-one machine comprises a crushing device, a squeezing device, an oil-water separating device and a biological treating device, wherein the crushing device is used for crushing kitchen waste into residue bodies with the food particle size of 0.1 to 0.3 millimeters; liquid in solid residues squeezed by the squeezing device accounts for 7 to 15 percent of the total weight of solid residues; the solid residues enter the biological treating device for treatment finally, and a microbial agent is put into a fermentation tank in the biological treating device, heated and subjected to batch-type stirring; the microbial agent consists of actinomycetes, lactobacillus, saccharomycetes and photosynthetic bacteria and are fed in a mass ratio of 3:5:7:4; 0.01 to 2 mass parts of the microbial agent are added into 100 mass parts of solid residues; and the fermentation time of the microbial agent is 3 to 15 hours. The integrated equipment is small in size, compost time can be shortened greatly, and the treatment efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of kitchen waste treatment, and in particular relates to an automatic kitchen waste recycling integrated machine and a treatment process thereof. Background technique [0002] The increasing amount of food waste and the disorderly collection, transportation and treatment methods have caused more and more serious environmental pollution and health problems. In particular, the outbreak of bird flu and the outbreak of dioxin and foot-and-mouth disease in European countries have aroused great attention from the governments of various countries. Developed countries have legislated one after another to prohibit the use of food waste that has not been harmlessly treated as feed to feed pigs. Incinerate food waste (prone to produce dioxin). my country has also begun to pay attention to this issue in recent years. Beijing, Shanghai, Guangzhou, Shenzhen, Hangzhou and other major cities have taken the lead in enacting...

Problems solved by technology

Nowadays, many enterprises or research institutes conduct research on kitchen waste, and have proposed various treatment equipment and methods. However, each section of equipment is configured independently. Due to the complex and cumbersome treatment process, the overall volume is too large, especially in solid waste. The treatment of food residues is relatively backward, and some need to undergo two fermentations, and the fermentation time needs to be as high as 24 hours to complete the composting, which obviously does not meet the current development needs, so how to develop simple and short composting time of food waste resources Chemical processing equipment has become particularly important
