Technology of processing pig manure organic fertilizer by using organic fertilizer production line in pig farm

The processing technology of pig manure organic fertilizer production line needs two steps to process commercial organic fertilizer: pre fermentation and processing part and deep processing granulation part. Small organic fertilizer equipment needs fermentation compost windrow turner, crusher, roller screen, mixer, fertilizer granulator machine, dryer, cooler, screen, coating machine, packaging machine, conveyor and other equipment.

Processing flow of pig manure organic fertilizer production line

1、 The recovered livestock and poultry feces are directly put into the fermentation area. After one fermentation and two aging stacking, the stink of livestock manure is eliminated. In this stage, the fermentation bacteria can be added to decompose the crude fiber, so that the particle size after crushing can meet the particle size requirements of granulation production.

2、 Smash the fermentation materials that have completed the secondary aging stacking process and enter the mixing and stirring system. Before mixing and stirring, according to the formula, add n, P, K and other trace elements into the mixing and stirring system and start mixing.

3、 The mixed materials are transported to the 
fertilizer granulator machine, the granulation enters into the cooling system after passing through the dryer, the materials are sieved after reaching the normal temperature, the qualified particles enter into the coating machine to wrap the coating film, and then the packaging is started, the unqualified particles are crushed by the crusher and then returned to the granulation system, and the granulation continues.

4、 Automatic packaging of finished products.

The main focus of organic fertilizer production line equipment is to solve the problem of tight resource and environment constraints and achieve sustainable development. We should vigorously promote the mechanization of resource-saving and environment-friendly agriculture, promote the mechanization of straw comprehensive utilization, conservation tillage and plastic film recycling in the organic fertilizer production line, strengthen the protection and efficient utilization of resources, promote the improvement of ecology and environment, and achieve a virtuous cycle and green development.
