High-efficiency conversion of cow dung fermentation tank

The treatment of cow dung in large-scale cattle farms has always been an environmental problem and a pain point in resource utilization that has plagued the industry. Our cow dung fermentation tank uses closed fermentation technology and intelligent control to achieve rapid decomposition, sterilization and deodorization of cow dung, and convert waste into high-quality organic fertilizer raw materials, providing a one-stop solution for farms and organic fertilizer companies. ​
The equipment adopts a horizontal closed tank design, which can process 10-50 tons of cow dung at a time. Through the “high-temperature aerobic fermentation” process, it can complete decomposition within 7-10 days, which is more than 60% shorter than the traditional composting cycle. The tank is equipped with a stirring device and an aeration system to fully contact the cow dung with the microbial agent. The fermentation temperature is stable at 55-65℃, which can effectively kill insect eggs, pathogens and weed seeds, and the harmless treatment rate reaches 99%. The organic fertilizer raw materials produced meet the national NY525-2021 standard. ​

The intelligent control system is the core advantage of the fermentation tank. Equipped with temperature, humidity and oxygen concentration sensors, the tank environment is monitored in real time, and the stirring frequency, aeration intensity and water replenishment are automatically adjusted through the PLC system. When the temperature is lower than 50℃, the heating device is automatically started; when oxygen is insufficient, the aeration frequency is increased to ensure that the microbial activity is always in the best state. The operator can complete the parameter setting through the touch screen, support remote monitoring, and accurately control the fermentation progress even in cross-regional management. ​
Outstanding environmental protection and energy-saving performance. The fully enclosed structure is combined with the biological deodorization module, and the ammonia removal rate reaches more than 90%, which completely solves the odor pollution problem of traditional composting; the tank body adopts a double-layer insulation design to reduce heat energy loss, and the energy consumption is reduced by 40% compared with open fermentation. The biogas generated during the fermentation process can be recycled and used as energy to heat the tank body, further reducing operating costs and realizing a circular economy.​
After a 10,000-head beef cattle farm in Inner Mongolia introduced the equipment, it processes 30 tons of cow dung every day and produces 8,000 tons of organic fertilizer raw materials annually. It not only solves environmental complaints, but also increases annual revenue by 1.2 million yuan through the sale of raw materials; after using it, an ecological farm in the Netherlands uses the fermented cow dung in its own farmland, increasing the soil organic matter content by 20% and the crop yield by 15%, realizing a virtuous cycle of combining planting and breeding. ​
