Abstract

The invention discloses high-efficiency kitchen waste aerobic fermentation equipment. The equipment comprises a fermentation bin, a grinding and dehydrating system, a stirring and pushing system, a heating system, a biological deodorizing system, an aeration system, a water supply system and an automatic control system. According to the fermentation equipment, kitchen waste compost is divided intofour stages including grinding, heating, high temperature and curing, and parameters of the heating system, stirring system, aeration system and water supply system can be independently set in each stage, so that parameters in three bins can be finely controlled, and effective performance of fermentation can be favored; and the dynamic respiratory index DRI is applied in the kitchen waste fermentation equipment to serve as an index for measuring product maturity, and the quality of mature fertilizer can be finally guaranteed by the advanced monitoring method.

Description

Technical field [0001] The invention relates to an efficient aerobic fermentation equipment for kitchen waste, which belongs to the technical field of domestic waste fermentation. Background technique [0002] Kitchen waste accounts for nearly half of domestic waste, and its effective treatment will help solve the problem of garbage siege currently facing my country. Kitchen waste contains nutrients such as sugars, proteins, lipids, etc., which can be decomposed and utilized by aerobic microorganisms under aerobic conditions, and finally converted into organic fertilizer with soil improvement effect similar to humus. However, kitchen waste has the characteristics of high moisture content, complex composition, and large size. If it is not handled in a timely manner, it will have a negative impact on the environment. The patent document of Chinese patent number CN108503398A discloses an intelligent, fully automatic, sealed and closed-type aerobic fermentation equipment for sanita...
