Manure dewatering machine is a key fertilizer processing equipment of manure drying system. It can adjust the moisture content of manure to a proper level, so that you can compost organic fertilizer quickly and easily. And in order to fully meet your requirements, we especially design many types of manure dehydrators according to different manure materials for your choice. Besides, even if you want to further process dehydrated manure into organic fertilizer, we also can design business plans according to your actual conditions.
Why we need to use manure dewatering machine in organic fertilizer production?
Animal manure is the most common material for organic fertilizer manufacturing, because it contains rich nutrients which are beneficial for the growth of crops and plants. But when you use fresh manure as fertilizer, it is necessary to remove excessive water from manure. Why? In general, there are two reasons as follows:
Making manure suitable for organic fertilizer composting
The reason why we cannot use animal manure as fertilizer directly is that it contains many pathogens, pest eggs and grass seeds. They are harmful to the soil and will affect the healthy growth of crops. So you need to compost manure before preparing organic fertilizer. In this process, it is essential to control the moisture content of manure between 40% and 60%. Which can meet the needs of water supply for aerobic fermentation and will not block the transport of oxygen.
Making manure easy to transport
In addition, fresh manure is a mixture of liquid and solids, so it is not convenient to transport to composting area. Especially cow dung, pig manure, etc. After processing with manure dehydrator, the solid animal manure will be separated from liquid and its moisture content can be reduced to 30%-40%. Only by driving forklifts can you transport manure to fertilizer composting area quickly and easily.
What kind of material can manure dehydrator machine process?
For organic fertilizer making, there are various materials for your choice. For animal manure, you can use chicken manure, pig litter, cow dung, etc. Can manure dewatering machine process all of them? Of course. We can provide you with the most suitable manure solid-liquid separator according to your material.
How does solid-liquid separator work to remove excessive water from manure?
Turn on manure dewatering machine
Our manure dewatering machine has an electrical control system, which makes itself easy to operate. This will makes you freely start and stop the host and pump. Therefore, only by employing one worker can it complete the whole manure dehydration process.
Feed manure materials
After set in motion, the pump will work to transport raw materials to the dehydrator. Here, we especially design inlet and overflow outlet for feeding manure materials into dehydrator more smoothly.
Dewatering
After feeding, it will start removing excessive water from manure. But as mentioned above, there are two types of manure dewatering machines, and they are different in dewatering methods. Screw type dehydrator only makes use of screw rotation part and sieve to extrude feeding manure. However, when it comes to inclined screen solid-liquid separator. It will separate solid manure from the liquid before starting extrusion.
Discharge
Finally, the hydrated manure will be discharged from the solid-liquid separator. Its moisture content is about 30%-40%. This can help you make manure into compost more smoothly.
How to further process dehydrated manure into organic fertilizer?
After dewatering, can manure be used as organic fertilizer directly? The answer is no. You need to further process it into compost. Because it still contains many pathogens, parasite eggs and grass seeds, which are harmful for the soil and not suitable for quality manure fertilizer production.Then, after manure composting, there are two choices for you.
