Pig manure organic fertilizer increases a lot of organic colloids and decomposes many organic matters into organic colloids with the help of microorganisms, which greatly increases the adsorption surface of soil, and produces a lot of sticky substances, which makes the soil particles cemented into stable aggregate structure, improves the soil water, fertilizer and air permeability performance, and the ability to adjust soil temperature.
Technological process of pig manure organic fertilizer production line
Pre fermentation part: a 3 m wide × 50 m long fermentation tank (capable of fermenting more than 200 tons of raw materials) needs to be built, and then the raw materials can be stacked in the fermentation tank, 1 kg of decomposition agent mixed with 20 kg of water, mixed in the raw material pile, 1 kg of decomposition agent can ferment 1 ton of raw materials, and the temperature is about 0 C ° and the fermentation cycle is 7-10 days, once every 2 days, it can be completely decomposed.
The raw material of organic fertilizer is fermented and decomposed, crushed by a semi wet material grinder, screened out by a roller screen, and then fermented. The fine material can be granulated, with a more beautiful appearance and higher granulation rate. After fermentation, the material (moisture content is 35%) is mixed by mixer, and then it is dried by organic fertilizer dryer, cooled by cooler, screened by drum screening machine, and returned to blender. Qualified products can be coated with calcium, magnesium, sulfur and other trace elements through coating machine, powder puffer, silo and packaging machine.
The pig manure organic fertilizer production process
needs two steps: the early fermentation and treatment part and the deep processing granulation part. Pig manure organic fertilizer equipment needs fermentation tipper, organic fertilizer grinder, drum screening machine, horizontal mixer, disc granulator, rotary dryer, cooler, screening machine, coating machine, packaging machine, conveyor and other equipment.
