The main material of the fermentation chamber is generally 304 stainless steel, and the double-layer structure is used to keep the temperature. The whole fermentation process is mainly carried out in the fermentation chamber. The main function of the spindle drive system is to stir the materials through the rotation of the spindle, so that the materials have good porosity and permeability. The hydraulic power system mainly provides power for the main shaft, blanking valve and oil cylinder. The main function of the feeding lifting system is to automatically lift the mixed materials to the top of the fermentation chamber to realize automatic feeding. The automatic discharging system mainly outputs the fermented materials through the discharging valve and belt conveyor. The air supply system is mainly used to deliver high-pressure air to the fermentation room to regulate the temperature and oxygen content in the fermentation room. At the same time, it is equipped with auxiliary heaters to maintain the optimal conditions for biological fermentation. The deodorization system is mainly used to collect and treat the gas discharged after fermentation by plasma method or biological method and discharge it after reaching the standard to avoid secondary pollution to the surrounding environment. Some organic fertilizer fermentation tanks are equipped with automatic control systems. Through oxygen concentration sensors, temperature sensors, air volume sensors and electric auxiliary heating devices, real-time online monitoring is carried out to automatically adjust the oxygen supply and temperature. Under the effects of ventilation, oxygen charging and stirring, it is ensured that the oxygen content and temperature are always in a good state of fermentation, and biological heat is used to a large extent to realize biochemical reaction and water evaporation, effectively shortening the fermentation cycle.

Tower type organic fertilizer fermentation equipment. The tower type fermentation process is to dehydrate or remove impurities from cattle manure, add auxiliary materials and microbial agents, mix and mix them, and then transport them to the top layer of the fermentation tower by belt conveyor. After that, the tower is turned over once a day, and the fermentation process is completed after 7 days. Tower fermentation has the characteristics of full utilization of heat, fast fermentation speed, low energy consumption, fast deodorization, good production environment, no climate impact, small land area and high degree of automation. The tower type organic fertilizer fermentation equipment operates automatically from the mixing and inoculation of organic matter, feeding and laying, turning to discharging, and can continuously feed and discharge. However, the fermentation tower equipment is not only expensive, but also has a high maintenance cost. Therefore, it has been gradually eliminated, and the manufacturers are fewer and fewer.
