Livestock and poultry manure is the most commonly used Manure raw material, which takes livestock and poultry manure as the main material and agricultural by-product processing wastes such as straw, weeds, leaves, chaff, etc. as auxiliary materials, such as distiller's grains, sawdust, etc; The method of fermenting Manure from livestock and poultry manure is mainly the harmless treatment of high-temperature fermentation, or the microbial treatment method dominated by Manure Fermentation starter. Proper temperature and proper stacking can achieve uniform and thorough fermentation and ripening of materials.

The process of livestock manure Organic fertilizer production line is: fermentation, crushing, mixing, granulation, drying, cooling, screening, film, packaging, etc. The fermentation is the same as that of small scale, requiring trough fermentation, etc. According to the process, the equipment fermentation tipper or dumper, material grinder, horizontal mixer (vertical mixer), Organic fertilizer granulator (Manure combined granulator, disk granulator, etc.), Manure drum dryer, cooler, drum screening machine, coating machine, automatic weighing and packaging scale, conveyor and other equipment are used in turn.
1、 Directly enter the recycled livestock and poultry manure into the fermentation zone. After one fermentation and two aging stacking, the odor of livestock manure is eliminated. At this stage, fermentation strains can be added to decompose the coarse fibers in order to meet the particle size requirements of granulation production after crushing.
2、 Crush the fermentation materials that have completed the secondary aging stacking process and enter the mixing and stirring system. Before mixing and stirring, according to the formula, add N, P, K, and other trace elements to the mixing and stirring system to start stirring.
3、 The mixed materials will be delivered to the Organic fertilizer granulator, and the granulated materials will enter the cooling system after being dried. The materials will be screened after reaching the normal temperature. The qualified particles will enter the coating machine to wrap the film and then start packaging. The unqualified particles will be crushed by the Organic fertilizer grinder and returned to the granulation system again to continue granulation.
4、 Automatic packaging of finished products.
