Manure is the main source of pollution in pig farms. Organic fertilizer production process
can perfectly solve the problem of fecal emissions, and the treated manure can also bring additional income to the pig farm. Pig farms can sell the treated pig manure to organic fertilizer producers. After a series of processing, the pig manure can be processed into nutrient rich ecological organic fertilizer. The process flow of the whole pig manure organic fertilizer production process is as follows:
Fermentation of pig manure organic fertilizer: if the moisture content in raw materials is too high, dry and wet separator can be used to reduce water content, or straw can be added to control water content. Fermentation can be started when the moisture content is controlled at 55%.
Fermentation process: according to the product to add organic fertilizer microbial agent, no requirement can be added. If you want to speed up the fermentation of raw materials, you can add organic fertilizer starter. During the fermentation process, the fermentation temperature should be controlled at all times to reach about 70 degrees, and the compost windrow turner should be used to flip until the fermentation is completed.
After fermented and decomposed, pig manure can be crushed by organic fertilizer crusher. If it is to produce powdered organic fertilizer, it can be directly packaged and stored. If granular organic fertilizer is produced, special organic fertilizer granulator should be used for granulation, and then the quality of pig manure organic fertilizer can be improved by organic fertilizer screening machine, organic fertilizer dryer and other equipment of organic fertilizer production line
