Manure is the main source of pollution in the farm. Organic fertilizer machine can perfectly solve the problem of Fecal Emission, and the treated manure can also bring extra income to the farm. The treated organic fertilizer can be sold to organic fertilizer producers. After a series of processing, the manure can be processed into ecological organic fertilizer with rich nutrition.
Adding 10% – 15% of the total amount of fermented pig manure with non-toxic and harmless sawdust or coarse rice bran, or adding chicken manure, can adjust the water content, ventilation and carbon nitrogen ratio, so as to control the water content of pig manure at about 60%. The C / N ratio is between 30 and 40. The second is to add superphosphate, which accounts for 5% of the total fermentation material, to adjust the pH of pig manure to about 7.5. The additives must be evenly mixed with pig manure and then stacked in a ladder shape in the pretreatment plant. The stacking trapezoid is 2m in width at the top and 3M in the bottom. The stacking strip is in the same direction as the gradient of the ground, so that the exudate can flow into the small ditch on the low side. The stacking time in the pretreatment plant was 7 days in summer and autumn, 10 days in winter and spring, and then it was fermented in fermentation tank.
The pretreatment procedures are as follows: fresh pig manure – adding fermentation bacteria – adding sawdust, rice bran, chicken manure – adding calcium superphosphate – uniform mixing – stacking in trapezoid for 7-10 days – sending to fermentation workshop
The organic fertilizer production line uses modern microbial technology, mainly livestock and poultry excrement, and bran, peanut shell powder, crop straw and other auxiliary materials as carriers. The bacteria and livestock and poultry excrement are fully mixed by mixing method, so that the microbial bacteria are connected to the livestock and poultry excrement, including dehydrator, fermentation turner, semi-wet material crusher, horizontal mixer, granulator, dryer, cooler, drum screening machine, film coating machine The bio-organic fertilizer produced by packaging equipment, belt conveyor and other equipment after a series of harmless treatment such as rapid heating, fermentation, decomposition and deodorization.
