Microorganism-controllable kitchen waste aerobic composting device and aerobic fermentation method

Abstract

The invention provides a microorganism-controllable kitchen waste aerobic composting device and an aerobic fermentation method. The device comprises a transmission system, a multi-return-stroke cabin,a microorganism transition device, and an air supply pressurization system, wherein the kitchen waste is located in the multi-return-stroke cabin, the microorganism transition device is located in the multi-return-stroke cabin, the transmission system is connected with the multi-return-stroke cabin and provides power, the air supply pressurization system is connected with the multi-return-strokecabin, and the microorganism transition device comprises a water bath pipeline, a radiation groove and a transition pipeline. According to the invention, microorganisms in the middle and later periodsof previous material fermentation can be transited to the early period of subsequent material fermentation through the microorganism transition device, so that the microorganism biomass in the earlystage of fermentation can be greatly improved, and the aerobic fermentation process is accelerated; and meanwhile, the microorganism temperature is adjusted through the design of the water bath pipeline, the number and biocide of microorganisms can be well controlled, and it is guaranteed that aerobic fermentation is safely and efficiently completed.

Description

technical field [0001] The invention relates to the technical field of food waste composting, in particular to a microbial controllable food waste aerobic composting device and an aerobic fermentation method. Background technique [0002] The materials of aerobic fermentation composting come from the organic components in domestic garbage and kitchen waste. Domestic garbage and kitchen waste need to be pretreated to extract organic materials for composting. Composting is the process of converting organic matter into fertilizers through the fermentation of microorganisms under certain moisture, ratio and ventilation conditions under artificial control. In this composting process, the organic matter is transformed from an unstable state into a stable humus substance, which does not pose a hazard to the environment, especially the soil environment, and the composting product is called nutrient soil. The use of aerobic microorganisms under aeration conditions is called "aerobic...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problems that traditional aerobic composting occupies a large area and takes a long time for aerobic fermentation, the present invention saves aerobic composting space by designing a multi-return structure in the food waste treatment device, and controls the food waste treatment process by temperature adjustment Microorganisms in the environment, the system design of multi-faceted structure effectively realizes the adjustment of the number of microorganisms and the control of the growth and death of microorganisms, which can ensure that kitchen waste can complete aerobic fermentation treatment safely and efficiently
