In order to improve the utilization value of livestock and poultry waste and reduce the environmental pollution caused by traditional treatment methods, it is necessary to increase the application of organic fertilizer technology. At present, livestock and poultry waste production of organic fertilizer process mainly includes the use of organic fertilizer granulating machine after fermentation, after fermentation to do powder products, and adding microbial agents to do biological organic fertilizer.

The processing process of livestock and poultry manure organic fertilizer production line: raw material treatment → harmless treatment → mixed ingredients → granulation → cooling screening → metering sealing → finished products storage.

For example, the production process of chicken manure organic fertilizer production line is: Organic fertilizer raw materials (animal manure, household waste, dead leaves, biogas residue, waste bacteria, etc.) after fermentation into the semi-wet material grinder for grinding, and then add nitrogen, phosphorus and potassium and other elements to make the mineral elements to meet the required standards, and then blender stirring, and then into the pelletizer (drum pelletizer, plate pelletizer, new organic fertilizer pelletizer, etc.) pellet, After drying, through the screening machine screening, qualified products for packaging, unqualified return granulator for granulation.

The use of livestock and poultry waste to produce organic fertilizer has broad market prospects and outstanding ecological benefits, which is an important development trend of livestock and poultry waste treatment in the future.
