The process of small-scale pig manure organic fertilizer production line
: ferment in the fermentation tank, evenly sprinkle the inoculant, turn over the pile for fermentation, ferment for 12-15 days, discharge, screening, crushing, premixing, granulating, screening, packaging and selling
1. Fermentation process of pig manure organic fertilizer production line
The main process of organic fertilizer production line is to mix the organic solid waste with less than 60% water content, auxiliary materials (plant straw, etc.), microbial fermentation agent, etc. evenly, and make it fully decomposed, sterilized, deodorized and dehydrated through pool aerobic continuous fermentation. The moisture content of the decomposed material is generally in the range of 30-35%. After screening and magnetic separation, it can be directly used for pelleting to produce spherical organic fertilizer or further drying to produce powdery organic fertilizer.
2. Granulation process of pig manure organic fertilizer production line
The production process of organic fertilizer granulation is mainly to screen the organic waste with 30-35% moisture content, granulation and drying after screening, add functional bacteria to produce bio organic fertilizer, and add nitrogen, phosphorus and potassium (the total nutrient amount is less than 15%) to produce organic fertilizer.
The production line of pig manure organic fertilizer varies from tens of thousands to hundreds of thousands according to the equipment configuration and production scale. For example, the annual output of 50-50000 tons of pig manure organic fertilizer production line needs 100000-800000 yuan, and the price of small-scale pig manure organic fertilizer production machine
is generally less than 100000 yuan.
