Composting fermentation is an important step in the production of organic fertilizer using livestock and poultry manure, and flipping is an important measure to improve composting efficiency and the quality of compost products. In the past, in the process of composting livestock and poultry manure to produce organic fertilizer, the fermentation and flipping of fertilizer consumed a lot of manpower, material resources, and financial resources. With the development of livestock and poultry manure composting technology, modern design methods, and industrial control technology in recent years, our company produces a dedicated organic fertilizer fermentation tank for livestock and poultry manure, which makes the fermentation effect of the material better and is highly praised by customers.
The working principle of horizontal organic fertilizer fermentation tank is to evenly mix waste (livestock manure, kitchen waste, domestic sludge, etc.), biomass (straw and sawdust, etc.) and returned materials in a certain proportion to make the moisture content reach the design requirements of 60-65% before entering the three-dimensional aerobic system. By adjusting the moisture, oxygen content and temperature changes of raw materials, the materials can be fully aerobic fermented and decomposed, The heat released during the decomposition process can increase the temperature of the material itself, with a maximum temperature of 95 ℃. The water in the fermentation material is evaporated as the temperature increases, and some organic matter is decomposed, thereby reducing the volume of the pile and achieving waste reduction treatment. The organic fertilizer fermentation tank controls the temperature between 65-75 ℃ through ventilation, oxygenation, stirring, and other functions to achieve the temperature for material fermentation treatment. At this temperature, a large number of pathogenic bacteria and parasites in the pile can die. At the same time, a deodorization system is used to treat the emitted gas with a foul odor, achieving the goal of harmless treatment. The product after high-temperature aerobic fermentation can be used for soil improvement, landscaping, landfill cover soil, etc.
The horizontal organic fertilizer fermentation tank has the following advantages:
1. High temperature aerobic fermentation, utilizing high-temperature microbial technology, has low energy consumption and operating costs;
2. The equipment occupies a small area and has a high degree of automation. One person can control it to complete the fermentation process;
3. By using biological deodorization equipment to achieve gas emission standards without generating secondary pollution;
4. The main body of the equipment is made of stainless steel special material, which reduces corrosion and has a long service life;
5. The main insulation design and auxiliary heating ensure the normal operation of equipment in low-temperature environments;
6. The treated domestic sludge, kitchen waste and livestock manure are used for processing organic fertilizer to realize resource utilization.
