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...

Embodiment 1

[0085] First, the food waste is collected into the crushing device for crushing. The particle size of the crushed food waste is 0.1-0.3 mm; the stirring speed is 3200 rpm, and the crushing speed is 50 kg / hour; the crushed solid-liquid mixture is sent to The solid-liquid separation is carried out in the squeezing device, and the liquid content in the solid residue after squeezing accounts for 15% of the total; the liquid squeezed out of the squeezing device enters the oil-water separation device for oil-water separation, and the solid residue enters the biochemical treatment device for treatment; among them, in the biochemical treatment In the device, the microbial agent is put into the feeding port of the fermenter, and heated and intermittently stirred in the fermenter, the heating temperature is controlled at 80°C, and the stirring speed is 60 rpm; the microbial agent is made of Composed of actinomycetes, lactic acid bacteria, yeast and photosynthetic bacteria, which are adde...
