The configuration of organic fertilizer production line in small farms should be comprehensively considered according to the scale of farms, manure yield, land demand and other factors. Here is a reference configuration scheme:1. Feces collection system: manual or semi-automatic collection equipment, such as feces forklifts, conveyor belts, etc.2. Fermentation system: vertical or horizontal fermenter is used, and the volume of the fermenter is selected according to the fecal output of the farm.3. Drying system: The use of hot air drying equipment, such as hot air stove, drying tower, etc., drying system should have good thermal insulation performance to ensure drying effect.4. Grinding system: The use of organic fertilizer crushers, such as chain shredders, drum shredders, etc., shredders should have high crushing efficiency and stability.5. Screening system: The use of screening equipment, such as vibrating screen, roller screen, etc., screening equipment should have good screening effect and wear resistance.6. Packaging system: The use of packaging machines, such as automatic packaging machines, semi-automatic packaging machines, packaging machines should have high packaging speed and stability.In short, the configuration of organic fertilizer production lines in small farms has important practical significance. Through rational allocation of organic fertilizer production lines, the harmless treatment and resource utilization of manure can be realized, and the economic, environmental and social benefits of livestock farms can be improved. I hope this paper can provide useful reference for small farms.
