Dry pig manure contains crude protein 10%-20%, crude fat 1%-3%, nitrogen-free extract 20%-30%, crude fiber 15%-30%, so it has high nutrients . Studies have found that dried pig manure can be fermented into high-quality organic fertilizer products. It can fluff the soil, improve soil compaction, chelate trace elements in the soil, and improve soil fertility.
Pig manure dehydrator is a kind of livestock manure dehydrator, which can separate the raw manure water of poultry manure such as pig manure, duck manure, pig manure, chicken manure into liquid organic fertilizer and solid organic fertilizer. Solid organic fertilizer can be transported and used in granular form through a granulator machine for fertilizer
. Liquid organic fertilizer can be directly used for crop utilization and absorption. Solid organic fertilizer can be transported to areas lacking fertilizer for use, and can also improve soil structure. At the same time, it can be made into organic compound fertilizer through fermentation. The mud pump is used to send the raw manure water into the machine, and the solid matter is squeezed and separated through the screw shaft arranged in the screen, and the liquid flows out from the liquid outlet through the screen.
Introduction of pig manure organic fertilizer process:
The recovered livestock and poultry manure directly enters the fermentation area. After primary fermentation, secondary aging and stacking, the odor of livestock and poultry manure is eliminated. At this stage, fermentation bacteria can be added to decompose the crude fiber in it, so that the particle size after crushing meets the particle size requirements of granulation production.
The fermented materials that have completed the secondary aging and stacking process are crushed and enter the mixing and stirring system. Before mixing and stirring, according to the formula, N, P, K and some other trace elements are added to the mixing and stirring system, and the mixing is started.
The mixed material is transported into the granulation system. The pig manure organic fertilizer production line recommends the use of a drum granulator
. This fertilizer granulator machine
can not only be an organic fertilizer granulator but also a compound fertilizer granulation. It is the most suitable in the fertilizer production line. The granules enter the cooling system after passing through the dryer, and the materials are brought to room temperature and then screened. The granules that meet the requirements enter the coating machine to wrap the coating film and then start packaging. The granules that do not meet the requirements are crushed by the crusher and returned to the manufacturing process. The granulation system continues to granulate.
The finished product is automatically weighed and packaged.
