With the rapid development of animal husbandry, a large amount of feces and sewage have been generated. The harmful elements in these feces seriously exceed the standard, making it difficult to treat them with traditional methods of returning them to the fields. In view of this situation, people have developed a Organic fertilizer production line with movable and efficient solid-liquid separation technology as the core and integrated fertilizer production equipment such as high-efficiency mixer, Organic fertilizer dumper, Organic fertilizer granulator, etc. The development and research of livestock manure Organic fertilizer production line and sterilization system will help to promote the formation of the industrial chain of harmless treatment, resource utilization and commercialization of livestock manure, achieve the goal of industrialization, marketization and large-scale production, and effectively promote the development of ecological agriculture and circular economy in the city.

The technical process of the small Organic fertilizer production line first combines chicken manure with a proper amount of straw powder. The amount of chicken manure mixed depends on the water content of chicken manure. Generally, 45% of the water content is required for fermentation, that is, when the chicken manure is kneaded into a ball by hand, water can be seen at the finger seams, but no water can be dripped. When the chicken manure is loosened, it can be dispersed. Then add corn flour and strain. The function of corn flour is to increase sugar for strain fermentation, so that multi-dimensional complex enzyme bacteria will soon occupy Absolute advantage. Then add the prepared mixture to the mixer for stirring, making sure to mix evenly and thoroughly without leaving any lumps. The mixed ingredients shall be stacked into a long strip 1.5 m-2 m wide and 0.8 m-1 m high, and shall be dumped by Organic fertilizer dumper every 2 days. Stacking takes 2 days to heat up, 4 days to odorless, 7 days to loosen, 9 days to become fragrant, and 10 days to become fertilizer. Specifically, on the second day of stacking, the temperature can reach 60 ℃ -80 ℃, killing diseases and pests such as Escherichia coli and insect eggs; On the 4th day, the odor of chicken manure was eliminated; On the 7th day, the compost became loose and dry, covered with white mycelium; On the 9th day, it emits a fragrance of koji; On the 10th day, the bacterial fertilizer will be fermented and matured. After a little drying, it can be crushed by a semi wet material grinder, granulated by a Organic fertilizer granulator, dried and dehydrated by a dryer, and screened by a screening machine. The finished Manure is ready for packaging and storage.

The products produced by the granular Organic fertilizer production line are made of chicken and pig manure as raw materials, without any Chemical composition. The digestion ability of chicken and pig is poor, and only 25% of the nutrients can be consumed. The other 75% of the nutrients in the feed are discharged with the manure, so that the dry products contain nitrogen, phosphorus, potassium, organic matter, amino acid, protein and other components. The chicken manure dryer has not only created economic benefits for enterprises, but also made significant contributions to human environmental protection projects.
