If pig manure is directly returned to the field, it will burn the roots and damage the seedlings. Pig manure can be processed into Manure through fermentation. Biogas, biogas slurry, pig manure complete set of Manure equipment processing Manure is a more suitable method for current farms. The whole process is mechanized, with less investment cost and quick cost recovery. The complete set of pig manure Organic fertilizer equipment is specialized in processing pig manure, which can make pig manure become Organic fertilizer through fermentation and harmless treatment, The nitrogen content of Organic fertilizer made from pig manure is very high. Pig manure Manure can maintain fertilizer and water, prevent diseases and pests, and increase crop yield.
The high moisture content of pig 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 composting machine is used for flipping. The purpose of flipping is to accelerate the fermentation speed, promote the entry of oxygen into the pile, 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: moderate temperature, high temperature, and cooling. The addition of 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 pile layer is generally at 15-45 ℃, and the suitable temperature for modern composting production is generally 55 ℃.
In the later stage of endogenous respiration, the remaining part is the organic matter that is difficult to decompose and the newly formed Humus. At this time, the activity of microorganisms decreases, the calorific value decreases, the temperature drops, and the thermophilic microorganisms take the advantage. The residual decomposed organic matter is further decomposed, and the Humus continues to increase and stabilize. When the compost enters the maturity stage, the oxygen demand is greatly reduced, and the water content is also reduced.
After fermentation, there is a pulverizer. The purpose of pulverization is to ensure the roundness of the granulation in the later stage. During pulverization, a semi wet material pulverizer can be selected, with a crushing particle size of 20-30 mesh. It can be used to pulverize the fermented decomposed waste or other materials with a moisture content less than 30%.
As Manure is produced, there are three types of Organic fertilizer granulators for granulation of Manure: disc granulator, agitating tooth granulator and new type of three in one granulator. The disc granulator has a long history, is simple to operate, and is relatively cheap. The agitating tooth granulator is highly mechanized. If the output is small, drying can be avoided and the new type of three in one granulator is mainly used for large annual output. After granulation, it is dried, cooled, coated, and packaged for sale.
