With the rapid development of livestock and poultry industry, a large number of feces and sewage are produced. The harmful elements in these feces are seriously over standard, so it is difficult to deal with them by the traditional way of returning them to the field. The manure and urine of a pig in a year can be retted into 2000-2500kg high-quality organic fertilizer, which contains 11-12% of organic matter, 0.45% of nitrogen, 0.19% of phosphorus pentoxide and 0.6% of potassium oxide. It can meet the annual fertilizer consumption of one mu of land. An organic fertilizer production line
can not only meet the local fertilizer demand, but also meet the demand of surrounding markets.
Pig manure production line mainly includes two parts: fermentation and production. The purpose of pig manure fermentation is to make it harmless and become a fertilizer with high content of organic matter. The fermented pig manure is loose and has no peculiar smell. It can be processed into powder or granular organic fertilizer according to needs, and finally packaged and sold by automatic packaging machine, which is the production part of organic fertilizer.
The flow of organic fertilizer production process
①Fermentation and deodorization of raw materials---②Raw material crushing----③Automatic batching system of raw materials----④Mixing-----⑤Organic fertilizer granulation, roller granulation, extrusion granulation, disc manufacturing Granules (a variety of organic fertilizer granulating equipment can be selected) ----- ⑥ Dryer drying organic fertilizer granules --- ⑦ Cooler (cooling and cooling organic fertilizer granules) ----- ⑧ Screening machine (screening Produce qualified organic fertilizer granules) ------⑨ Coating machine coated granules (increases the gloss of the product and sells well, and the coating raw materials have no adverse effect on the fertilizer efficiency) -----⑩Packing machine (automatic weighing, filling Bag, automatic sealing).
