In recent years, the large-scale application of chemical fertilizers has severely damaged the soil structure and affected the yield and quality of agricultural products. The organic fertilizer manufacturing process processes cow dung, and the organic fertilizer produced by the fermentation compost turning machine can improve the damaged soil structure, improve the quality of agricultural products, and protect the ecological environment.
Introduction of cattle manure fermentation turner
Compost turning machine can transform cow manure, agricultural waste, domestic garbage sludge and other wastes into organic fertilizer to improve soil properties. The advanced fermentation technology of cattle manure composting dumper is microbial aerobic fermentation. The compost turner is designed according to the principle of aerobic fermentation, so that the fermentation bacteria can give full play to its function.
If the compost pile is too high, anaerobic state will be formed in the compost pile, so that the function of fermentation bacteria can not be fully played, which will affect the quality of fertilizer and its production. The equipment can be used with solar fermentation chamber, fermentation tank and moving machine, and can realize the function of one machine with multiple tanks. After fermentation, the compost was processed by NPK fertilizer granulator.
Technological process of cattle manure compost turning machine
Chicken manure, pig manure, cow manure, sludge, straw, crop straw, leaves, weeds, sawdust, distiller's grains, furfural residue and other organic wastes were used as raw materials. The moisture content of raw materials should be controlled at about 70%. If there is less moisture in raw materials, it should be watered thoroughly to ensure proper moisture content.
After 24 hours composting, the temperature in the pile can reach 50 ℃ or so, and it can rise to 70 ℃ in 48 hours. When the temperature reaches 70 ℃, it starts to be thrown once. After several days of continuous high temperature composting, the pile temperature gradually decreases. About two weeks, the raw materials are all rotten, the insect eggs, grass seeds and pathogenic bacteria in the raw materials are all killed, and the straw turns brown or dark brown Collapse 1 / 3 or 1 / 2.
The raw material after fermentation is soft and elastic, and it is brittle and easy to break when dry. At this time, the fermentation process of straw and other raw materials is completed.
