Fermentation equipment with improved mixing ventilation device and application method of fermentation equipment

Abstract

The invention discloses fermentation equipment with an improved mixing ventilation device and an application method of the fermentation equipment. The fermentation equipment comprises a fermentation tank, a mixer shaft is longitudinally arranged in the center of the fermentation tank, rotten layer mixing units, fermentation layer mixing units and preheating layer mixing units are horizontally arranged on the mixer shaft from top to bottom, mixing arms are arranged on the mixing units, vent holes communicated with an air duct are formed in the mixing arms of the rotten layer mixing units and the fermentation layer mixing units, and the number and/or the pore diameter of the vent holes in the mixing arms of the rotten layer mixing units are/is greater than the number and/or the pore diameter of the vent holes in the mixing arms of the fermentation layer mixing units. Through improvement of the mixing and ventilation structure of the fermentation equipment, sufficient ventilation in mixing is realized, energy consumption of the fermentation equipment is lowered, sufficient fermentation is achieved, water content of fermentation materials is reduced.

Description

technical field [0001] The invention belongs to the field of organic fertilizer fermentation, and more specifically, the invention provides a closed aerobic fermentation equipment with an improved agitation and aeration device for treating livestock and poultry manure. Background technique [0002] In China, the rapid development of the livestock and poultry breeding industry has played an important role in the development of the rural economy and the increase of farmers' income. At present, less than 5% of my country's livestock and poultry breeding enterprises have carried out harmless treatment or resource utilization of livestock and poultry manure, and most cities The livestock and poultry breeding industry has polluted the local environment, and it is necessary to control the pollution of livestock and poultry manure. At present, the most commonly used methods for domestic treatment of livestock and poultry manure are: direct return to the field, drying, and drying for ...

AI Technical Summary

Problems solved by technology

[0004] However, the closed livestock and poultry manure fermenters currently available on the market still have problems such as insufficient fermentation, high energy consumption, and high water content in fermented materials.
