Compared with the traditional composting fermentation, the fermentation of livestock and poultry manure by using organic manure fermentation tank has the following advantages: small floor area, high degree of automation, and one person can complete the whole fermentation process; Achieve gas emission up to standard through deodorization system without secondary pollution; The main body of the equipment is made of special stainless steel to reduce corrosion and long service life; The main insulation design and auxiliary heating ensure the normal operation of the equipment in low temperature environment. Using fermentor to ferment livestock manure has the following disadvantages: large investment in organic fertilizer equipment, high energy consumption and high operation cost; Because the traditional compost is greatly affected by the external temperature, compared with the traditional compost, the production efficiency of the organic fertilizer fermentation tank is lower in the warm season and higher in the cold season.
Tank type organic fertilizer fermentation equipment. The equipment required for tank fermentation is the tank fermentation dumper, which has the advantages of large processing capacity, small land occupation, simple operation, driverless and so on. However, due to the construction of fermentation tank, the fermentation field is fixed, which has certain limitations, and the air permeability is not as good as the strip stack type. At present, based on the function of turning and throwing, some trough fermentation organic fertilizer dumpers are designed with oxygenation devices to increase air permeability; Some add the function of crushing and stirring, which is suitable for fecal type, dregs and fermented products with more fiber and less viscosity. In this way, the pretreatment processes of raw material stirring and crushing can be saved and the production links can be reduced. The trough organic fertilizer dumper is mostly driven by motor because it walks on a fixed track, and its price is mainly related to its motor power.
