Cow dung is also one of the raw materials for liquid bio fertilizer. To make liquid biofertilizer from cow waste, it needs to go through dehydration, precipitation and filtration of impurities, disinfection, nutrient ratio, anaerobic fermentation.
How to dehydrate the liquid in cow waste?
Using animal dung dewatering machine can effectively extract liquid components from dung. It has two types: spiral extrusion type and inclined screen type. Because the water content of fresh cow dung is usually 60%-80%, it is most appropriate to use a spiral dehydrator. After dehydration, the water content of cow dung is 20%-30%. It can be made into powdered or granular biofertilizer.
How to remove impurities from cow dung wastewater?
In order to obtain pure cow dung liquid bio fertilizer, you need to remove a large amount of impurities contained in it. First, you can build a sedimentation tank to precipitate the visible impurities in it. Then, use a filtration device to remove other impurities in the cow manure wastewater, such as silt, grass clippings, etc.
How to kill pathogens in filtered cow dung wastewater for making liquid biofertilizer?
The filtered cow manure liquid contains some harmful substances such as pathogens or insect eggs. Using a sterilization device can be of great help. So, in this step, YUSHUNXIN has configured two UV sterilization devices for the liquid bio fertilizer production line. Its sterilization effect can reach 99%. After sterilization, you can get high-quality cow dung bio liquid fertilizer.
How do I ferment to manufacture liquid biofertilizer from cow waste?
After the above steps, you need to ferment the obtained cow dung liquid. In order to shorten the fermentation time, you can add auxiliary materials such as fermentation agents. In addition, you can also add nutrients such as nitrogen, phosphorus, and potassium to the mixture to increase the nutritional content of the biofertilizer. After the ratio is completed, the fermentation tank is equipped with a stirring rod to stir evenly. Then proceed to anaerobic fermentation.
The above is the complete steps to manufacture liquid biofertilizer from cow waste. There are whole sets of liquid bio fertilizer making machines on sale in YUSHUNXIN company.
