The process flow of producing fertilizer from livestock and poultry manure organic fertilizer production line
Animal manure is a relatively high-quality organic fertilizer, which contains pure nitrogen, phosphorus (P2O5), and potassium (K2O) of about 1.63%, 1.54%, and 0.085%. Livestock and poultry manure must undergo maturation with a composting agent before application, to inactivate and deodorize parasites and their eggs, as well as infectious pathogens present in livestock and poultry manure, through the process of maturation.
The production process of animal manure organic fertilizer is closely related to the equipment configuration of the organic fertilizer production line. Generally, the complete set of equipment for the organic fertilizer production line mainly consists of a fermentation system, a drying system, a deodorization and dust removal system, a crushing system, a batching system, a mixing system, a granulation system, a screening system, and a finished product packaging system.

The process flow of the organic fertilizer production line for producing fertilizers from livestock and poultry manure:
1. The ratio of raw materials per ton is 500 kilograms of pig manure (or other animal manure), 300 kilograms of auxiliary materials, 200 kilograms of bacterial residue, and 100 grams of RW bacterial agent;
2. Stacking, according to the above raw material ratio, according to the needs, the stacking length is unlimited, with a width of 4 meters and a height of 2 meters. When stacking materials, it is necessary to stack them layer by layer evenly;
3. Add the bacterial agent, expand the volume of the bacterial residue in a 1:5 ratio, mix evenly, and sprinkle it on the surface of the pile according to the number of piles;
4. Stir and ferment, use a blender to stir the pile evenly. After the temperature rises to 60 degrees Celsius or above, flip the pile every 4-5 days. After 15 days of fermentation at 60 degrees Celsius or above, fold the pile up;
5. Screening processing, fermentation is carried out according to the above steps, and after screening and deep processing, it becomes pure organic fertilizer;
6. Granulation refers to the granulation of fermented pure organic fertilizer. Choose granulators based on different raw materials, such as disc granulators, extrusion granulators, and integrated extrusion ball throwing machines;
7. Drying, cooling, and packaging: Newly made particles have a relatively high moisture content and need to be dried to below 20% of the organic fertilizer standard. The dried particles of organic fertilizer are cooled by a cooling machine before being directly packaged.
