Cow manure reuse for padding
The organic fertilizer fermentation tank is also called the “padding producer “. The main principle is that manure is mixed and lifted to the solid-liquid separator. The separated solid manure is continuously squeezed into the fermentation drum during the second time squeezing. Under the automatic mode, the fan blows the oxygen required for fermentation in the tank. According to the different use of the material, cow bedding padding or fermented organic fertilizer, the fermentation time ranges between 8 and 24 hours. The temperature in the tank body should be kept at 55℃ to75℃. After fermentation, the bacteria and worm eggs can be eliminated by up to 99%. In the end, manure reaches 40% to 45% moisture content and can be used as padding or organic fertilizer.
1、Recycled manure is used for aerobic fermentation in thermostatic fermentation tank. The fermented manure can be processed into padding or organic fertilizer, achieving waste utilization and cost-efficiency.
Dimensions: L: 17m, W: 2.9m, H: 2.85m.
2、Up to 70 m3 of separated solid manure can be processed per day for padding of 3,000 mixed dairy cows.
3、The fermentation tank is made of hot-rolled steel sheet of 15mm with anti-corrosion treatment. The tank has a volume of 70 m3 and is equipped with an insulated container, providing excellent thermal insulation.
4、The fermentation tank is driven by four geared motors of 4 kW power, and supported by 8 sets of symmetrical cylindrical supports. The fermentation tank features in stability and low consumption.
5、Without any heating, the temperature inside the fermentation tank will automatically rise to 60℃ and the highest temperature can reach to 75.5℃. The control system will automatically start the fan and adjust the fermentation tank speed to prevent the temperature increasing too fast, suitable temperature range being controlled.
6、99.9% harmful pathogens and weed seeds can be killed when the temperature of 55℃to 75℃ is kept for 8 to 24 hours with only natural microbial aerobic fermentation.
7、With the temperature monitoring system, four temperature sensors are mounted to real-time monitor the temperature inside the tank, material temperature at the inlet, the material temperature in the middle position of the fermentation tank and the material temperature of the outlet.
8、Equipped with SIEMENS inverter, PLC and touch screen, automatic control system is realized via Chinese operation page and unique design procedures.
9、The control system can remotely monitor and transmit data through the ranch network and the wide area network to ensure the normal operation of the system and remote upgrade services.
三、 Functional characteristics
1、Process intelligent control: Fermentation and deodorization can realize intelligent control, less manual operation, convenient management and stable effect.
8、No secondary pollution: The equipment is fully sealed and the internal ventilation and deodorization facilities can be used to achieve odor-free operation and ensure the environmental quality of the plant.
