Bed-type fermentation equipment, the main structure of the equipment frame is galvanized steel and pickled and phosphate steel, and the whole frame is sprayed with special materials, which greatly increases the service life of the equipment. The contact position of the fermentation bed and feces is all made of 304 stainless steel including screws. The operating principle of the equipment adopts the heat generated by natural fermentation of feces, and the heat is efficiently recovered to continuously support the stability of the overall fermentation. Each raw material of the fermentation requires about 7-10 degrees of electricity. When the temperature is low, an electromagnetic heating auxiliary system is used. The raw materials are fermented in the equipment for 48 hours to achieve deodorization, insecticide, decomposing, and low moisture content in the fertilizer.
