The treatment of pig manure granular organic fertilizer mainly has two steps: pre-fermentation treatment part and the deep processing granulation part.

Swine manure organic fertilizer production line is based on fresh pig manure as raw material, after a series of processing, processing organic manure needs two steps: early fermentation and treatment part and deep processing and granulation part.

Characteristics of pig manure organic fertilizer production line:

1. The main material in pig manure organic fertilizer is organic matter, and pig manure organic fertilizer increases the content of organic matter in the soil. Organic matter can improve soil physical, chemical and biological properties, ripen the soil and enrich the soil.

2, pig manure organic fertilizer, make the soil particles cemented into a stable aggregate structure, improve the soil water retention, fertilizer retention and air permeability performance, as well as the ability to regulate soil temperature.

Fermentation treatment part:

The early stage of the fermentation part: to build a 3 m wide x 50 meters long (more than 200 tons of fermentable material) fermentation tank, also can be more than one slot, then stacked materials (feces, renewal, straw) in fermentation tank, 1 kg of rotten agent can 1 tons of raw materials, fermentation by comparing mixed raw materials, the temperature is about 0 ° c fermentation period for 7 to 10 days, throw a 2-3 days, can be completely rotten.

After the pig manure is fermented and decayed, it is crushed by the semi-wet material crusher and screened by the roller. The coarse material is screened out and then fermented. The fine material can be granulated, and the particle appearance is more beautiful and the granulation rate is higher.

Granulation processing part:

After the fermentation, the materials are crushed and screened. After the undersize is granulated, it is sent to the dryer and then cooler. Finally, they are packaged and sorted into the warehouse. The unqualified oversize is returned to the crushing process for reuse.

The entire organic fertilizer production process specifically includes physical dehydration → mixing (proportional mixing of bacterial species + fresh animal manure + crushed crop straw) → fermentation → crushing → granulation → drying → cooling → sieving → finished product → packing→warehousing.
