With the rapid development of livestock and poultry farming, the intensive and centralized livestock and poultry manure produced by animal husbandry is too large in some areas, which cannot be absorbed by traditional fertilization treatment methods. On the other hand, due to the rapid development of the chemical fertilizer industry, people use a large amount of chemical fertilizers, which makes the amount of organic manure idle, and the basic soil nutrients show a gradual downward trend in some places.
In order to improve the utilization value of livestock and poultry breeding waste and reduce the environmental pollution caused by traditional treatment methods, it is necessary to increase the application of organic fertilizer technology. At present, the process of producing organic fertilizer from livestock and poultry breeding waste mainly includes the use of organic fertilizer granulator machine to granulate after fermentation, to make powdered products after fermentation, and to add microbial inoculants to make bio-organic fertilizer.
The processing flow of livestock and poultry manure organic fertilizer production line: raw material treatment → harmless treatment → mixed ingredients → granulation → cooling and screening → metering and sealing → finished product storage.

For example, the production process of chicken manure organic fertilizer production line is as follows: organic fertilizer raw materials (animal manure, domestic waste, dead branches, rotten leaves, biogas residue, waste bacteria, etc.) are fermented and then enter the semi-wet material pulverizer for pulverization, and then add nitrogen, phosphorus and potassium. and other elements to make the contained mineral elements meet the required standards, and then a mixer is used for mixing, and then enters the granulator (drum granulator, disc granulator machine, new organic fertilizer granulator, etc.) Dried, sieved through a sieving machine, qualified products are packaged, and unqualified products are returned to the granulator for granulation.
The use of livestock and poultry waste to produce organic fertilizer has a broad market prospect and outstanding ecological benefits, which is an important development trend of livestock and poultry waste treatment in the future.
