How to ferment pig manure?
Pre-fermentation part of pig manure: It is necessary to build a fermentation tank with a width of 3 meters x 50 meters in length (which can ferment more than 200 tons of raw materials). In the fermentation tank, 1 kilogram of decomposing agent is mixed with 20 kilograms of water, and mixed in the raw material pile. 1 kilogram of decomposing agent can ferment 1 ton of raw materials. Mix according to the raw materials.The fermentation cycle is 7-10 days when the temperature is around 0C, and it can be completely decomposed by turning once every 2 days.
Pig manure organic fertilizer equipment part: the fermented material (with a moisture content of 35%) is blended by a mixer, passed through a granulator, and then dried by a dryer, cooled by a cooler, and then passed through a screener. The unqualified products are screened by the screening machine, and the unqualified products are returned to the mixer. After passing through the coating machine, the qualified products can be coated with calcium, magnesium, sulfur and other medium and trace elements, and can pass through the silo and packaging machine.
Small-scale pig manure organic fertilizer production process: organic fertilizer raw materials are fermented and then pulverized by a semi-wet material pulverizer, screened through a drum screen, and the coarse materials are screened out and then fermented. The fine materials can be granulated.The screened fines can be bagged and sold as powdered organic fertilizer. Welcome to contact us for details.
