Equipment and process of organic fertilizer production line for cow manure fermentation

With the rapid development of intensive, large-scale, and specialized animal husbandry in China, the pollution of concentrated discharge of cow manure on the environment and the comprehensive utilization of cow manure are becoming increasingly prominent. However, cow manure not only contains a large amount of essential nutrients for plants such as organic matter, nitrogen, phosphorus, and potassium, but also contains various enzymes and microorganisms. Cow manure, as fertilizer, plays an irreplaceable role in fertilizers.

The general complete set of cow manure organic fertilizer equipment mainly consists of fermentation system, drying system, deodorization and dust removal system, crushing system, ingredient system, mixing system, granulation system, cooling and drying system, screening system, and finished product packaging system.

The equipment of the cow manure fermentation organic fertilizer production line can use an aerobic composting machine for early fermentation treatment, including raw material pretreatment, fermentation, maturation and other processes. Under natural ventilation conditions, composite microbial fermentation agents are added to the material, and the flat stacked ground is used for fermentation. According to the internal temperature of the material pile, mechanical control is used to flip the pile in a timely manner. In the post ripening stage, aeration fermentation, drying, and screening are used to produce powdered bio organic fertilizers, or granular organic fertilizers (spherical or cylindrical particles) are produced by granulation according to market demand.

The equipment for the organic fertilizer production line of cow manure fermentation, poultry manure, and livestock manure are fermented by a composting machine, crushed by an organic fertilizer crusher, and screened by a screening machine. After being fully fermented and matured in a fermentation tank, they enter the granulation stage. After being granulated by an organic fertilizer granulator, the particles are spherical with an organic matter content of up to 100%, achieving pure organic matter granulation. The processed organic fertilizer particles are solid and can be sieved after granulation, reducing drying energy consumption.
