Compact kitchen waste aerobic fermentation equipment

Abstract

The invention provides compact kitchen waste aerobic fermentation equipment, which is composed of a reaction chamber with a stirrer, a cooling water circulating and condensate water collecting system, an air heating ventilation system having the function of deodorizing, a water bath heating and thermal insulation system, and an intelligent control system with a remote supervisor; a travel switch is arranged in the reaction chamber and used for changing the stirring direction of a motor; a heater and a temperature sensor are arranged in a water bath cavity; heat is supplied to the reaction chamber in time according to reaction requirements; a thermal insulation interlayer is outside the water bath cavity and used for insulating the chamber; the air heating ventilation system is capable of ensuring enough oxygen concentration in the reaction chamber in the treatment process; the cooling water circulating and condensate water collecting system is capable of condensing and guiding out water vapour in the reaction chamber in time; a tail gas deodorizing system is capable of preventing secondary pollution to the environment by malodorous gas in the reaction chamber; and the equipment is controlled to operate by a PLC (Programmable Logic Controller) intelligent control system. The compact kitchen waste aerobic fermentation equipment disclosed by the invention is simple in structure, high in space utilization rate, low in operation energy consumption and good in processing effect.

Description

technical field [0001] The invention belongs to the field of organic solid waste treatment and resource recovery technology, and is especially suitable for the treatment and disposal of organic waste such as kitchen waste. Background technique [0002] Food waste mainly comes from food processing leftovers (kitchen waste) and food residues (swill) produced in the catering service industry, households, canteens of enterprises and institutions, etc. With the rapid development of our country's economy and the gradual acceleration of urbanization, the output of kitchen waste has increased significantly nationwide. In large and super-large cities such as Beijing, Shanghai, Shenzhen, etc., the output of kitchen waste The daily output has reached thousands of tons, and the annual output of food waste in the country has reached 10 million tons. With the continuous advancement of urbanization, more and more attention has been paid to food safety and environmental safety, and the tra...

AI Technical Summary

Problems solved by technology

At present, the treatment technologies of food waste mainly include landfill, incineration, feed treatment, anaerobic fermentation and aerobic composting, etc. Among them, anaerobic fermentation and aerobic composting have more potential, but the treatment cycle of these two methods is relatively long , it is difficult to meet the daily production and clearance requirements of food waste
