If pig manure is directly returned to the field, it will burn the roots and damage the seedlings. Pig manure can be processed into organic fertilizer through fermentation, biogas, and biogas slurry. The complete set of pig manure organic fertilizer equipment processing organic fertilizer is a more suitable method for current breeding farms. The whole process is mechanized, with low investment costs and fast cost recovery. Our company’s complete set of pig manure organic fertilizer equipment is professional in processing pig manure, which can make pig manure undergo harmless fermentation treatment and become organic fertilizer, The organic fertilizer made from pig manure has a very high nitrogen content. Pig manure organic fertilizer can maintain fertilizer and water, prevent diseases and pests, and increase crop yield..jpg)
The high moisture content of livestock and poultry manure requires the addition of crop straw, on the one hand to regulate the moisture content, and on the other hand to regulate C/N. After adding biological strains to livestock and poultry manure, a tank type turner is used for flipping. The purpose of flipping is to accelerate the fermentation speed, promote oxygen to enter the pile body, accelerate the fermentation process, and shorten the fermentation cycle.
The fermentation process should be noted that it should be flipped and thrown every 2-3 days. The fermentation process generally goes through three stages: medium temperature, high temperature, and cooling. Adding biological strains during the fermentation stage can kill a large number of harmful bacteria during the high-temperature process. In the intermediate temperature stage, the stack layer is generally at 15-45 ℃, and the suitable temperature for modern composting production is generally 55 ℃.
In the late stage of endogenous respiration, the remaining part is composed of organic matter that is difficult to decompose and newly formed humus. At this time, the activity of microorganisms decreases, heat generation decreases, temperature decreases, and thermophilic microorganisms take the advantage. They further decompose the remaining decomposed organic matter, and the humus continues to increase and stabilize. Composting enters the mature stage, with a significant decrease in oxygen demand and moisture content.
After fermentation, the organic fertilizer crusher is used for crushing, with the purpose of achieving rounded granulation in the later stage. A semi wet material crusher can be used for crushing, with a particle size of 20-30 mesh. It can be used to pulverize fermented waste or other materials with a moisture content less than 30%.
Due to the production of organic fertilizer, there are three types of granulation machines for organic fertilizer granulation: disc granulation, stirring tooth granulation, and new three in one granulation. The disc granulation process has a long history, is relatively simple to operate, and the price is relatively cheap. The stirring tooth granulation has a high degree of mechanization, and if the yield is small, there is no need for drying and can be directly dried. The new three in one organic fertilizer granulation machine is mainly aimed at those with larger annual output. After granulation, it is dried, cooled, coated, and packaged for sale.
