Pig manure is a good fertilizer for crops. Pig manure can be effectively utilized after processing. The random discharge of pig manure will have adverse effects on the environment. The utilization of pig manure resources for agriculture can improve the yield and quality of crops and achieve effective control of pig manure. Pig manure is made into organic manure, which has high practical application value due to its innocuous treatment. Moreover, the production of organic fertilizer by pig manure fermentation does not require much investment, and only a simple organic fertilizer production line can complete the transformation.
Pig Manure Fermentation
Rice straw and corn straw were crushed and pig manure was dried. Pig manure is the main raw material for fermentation and the other is the auxiliary material. All raw materials are put into the tank fermentation tank for composting fermentation. Pig manure composting process is mainly divided into four stages: heating, high temperature, cooling and late maturation. In the whole composting process, adding straw can accelerate the decomposition rate of pig manure compost. Through the trough turning machine, the material was dumped on time to increase the oxygen content of the compost. The trough turning machine has a strong ability to dump, which improves the fermentation speed and quality of pig manure. At the end of composting, pig manure meets the composting maturity criteria and has no harmful effect on crops. Fermentation and decomposition of pig manure can improve the total nutrient content of compost products. Cellulose and hemicellulose are degraded to varying degrees. The degradation rate of pure pig manure compost is the highest, but lignin is difficult to degrade.
Organic fertilizer production line equipment can make decomposed pig manure into organic fertilizer products which are easy to store and transport. The processing technology of organic fertilizer production line is mainly crushing, mixing, granulating, drying, cooling, screening and packing. Granulation is the core treatment of organic fertilizer production equipment. New type organic fertilizer granulator is widely used in organic fertilizer granulation treatment. Organic fertilizer granulator can granulate animal manure, straw and other fermentation products. The granular products are spherical, beautiful and convenient to use.
