Poultry and livestock manure are one of important raw materials sources for organic fertilizer production. Through aerobic composting, animal manure can be turned into quality fertilizer. Then how to make the compost with animal manure? In the organic fertilizer production industry, there are four composting methods. They are static composting, windrow composting,groove composting and in vessel composting. You can know the detailed composting process from the following.
How to treat poultry and livestock manure using static composting?
The static composting system is also called natural fermentation. After mixing poultry and livestock manure with some auxiliary materials, the fertilizer producers will pile the materials into stack. And they place an aeration system under the composting pile to supple oxygen. This composting method is a fermentation system with low-cost. However, there are some disadvantages of static composting, like long fermentation cycle, large land occupation. Therefore, it is not suitable for fertilizer plant. Compared with this fermentation method, the following three composting methods are much widely used in organic fertilizer production.
What is the animal manure windrow composting process?
When using windrow composting, you should stack the poultry and livestock manure into long strip type. While fermentation, you’d better use the self-propelled compost turner machine like crawler type composter and movable type composter to turning the organic manure. The machine can shorten the animal manure fermentation time and improve the composting efficiency. What’s more, the windrow composting system can also save infrastructure construction cost. It is suitable for small to large organic fertilizer plant.
How to compost the animal waste in the groove?
The groove type composting is carried out in the fermentation workshop. Before composting, the fertilizer manufacturers place the mixture which includes animal manure and agricultural by-products in the groove. Then they use the groove type compost turning machine to treat the organic materials. As for groove type compost turner machine, you can select rail type compost turner, wheel type compost turner or chain plate type compost turning machine. In addition, this groove type compostiing method is more automated than windrow composting system. This type of composting system is also available in small to large fertilizer production plant.
What is the in vessel composting system for animal manure disposal?
Differ from the other three composting systems, In-vessel composting system is a kind of fully automatic composting method. When applying this method, you’d better use the fermentation tank. When composting, You can put animal manure and auxiliary materials into the vessel. The vertical fermentation pot machine will mix,crush and ferment the organic materials in a short time. The in-vessel composting system has the characteristics of short fermentation cycle, better composting effect and high cost. This composting method is more suitable for large scale organic fertilizer manufacturing plant.
Generally, the composted animal manure can be applied directly. However, you should further process the compost manure when producing the commercial organic fertilizer.
For groove type, windrow type and in-vessel type composting system, FPC produces corresponding compost turner machines. You can find different models of compost turning machines in FPC. Welcome to our website to get the latest quoted prices of compost turning machines.
