Besides making solid fertilizer from cow manure, you also can choose to dispose cow dung waste into liquid fertilizer. For this, we can offer you customized cow manure liquid fertilizer production plan and machines.
6 Steps to make liquid fertilizer from cow dung
In general, to dispose of cow dung into quality liquid organic fertilizer, it needs 6 steps.
Collect Fresh Cow Dung for liquid fertilizer making
Usually, quality liquid water-soluble fertilizer manufacturing starts by collecting fresh cow dung. It’s essential to use fresh dung because it contains a higher concentration of nutrients and beneficial microorganisms compared to older, dried dung.
Filter liquid for fertilizer production
It contains 2 parts. For one thing, removing solid cow manure from the liquid. Here, you can use a manure solid and liquid separator. For another, filtering small particles from liquid cow manure material. So, you can produce water soluble fertilizer which is easier to use. Here, our engineer adopts activated carbon filtering design.
UV Sterilization
Then in order to eliminate harmful pathogens, viruses, fungi, etc to ensure the safety of produced liquid fertilizers. As the name suggests, our system to make liquid fertilizer from cow dung adopts UV sterilization technology. Its pathogens elimination rate can reach 99%.
Auxiliary material adding to improve nutrient content of final liquid fertilizer
If you want to add some NPK, trace elements to improve nutrient content or molasses or fermentation agent to speed up the liquid fertilizer fermentation, there is batching tank for you. Mixing additives with water, the batching tank will send then to liquid cow manure fermentor according to required proportions.
Liquid cow manure fertilizer mixing and fermentation
For producing liquid fertilizer from cow dung, fermentation is important. Similar with solid cow manure fertilizer production, it is a harmless process of liquid fertilizer. With stainless steel liquid fertilizer reactor mixing, enzymatic hydrolysis will take place to decompose nutrient substances into smaller molecules and further eliminate harmful pathogens in materials.
Cow manure liquid fertilizer packing
Finally, for commercial liquid fertilizer production, you need to packing finished cow manure fertilizer. For this, automatic liquid filling machine is the best choice. It can finish liquid fertilizer filling, covering, labeling, etc.
Can we make dry cow manure into liquid fertilizer?
Of course. To processing dry cow manure into liquid fertilizer, it is advisable to add water before liquid fertilizer fermentation. Here, YUSHUXIN can provide you with reverse osmosis equipment, which can offer high-purity water for cow manure liquid fertilizer manufacturing. It can purify municipal tap water, non polluting groundwater or surface water and lake water.
Generally, the ideal dry cow dung liquid fertilizer production process is cow dung crusher→ reverse osmosis equipment (water adding)→baching tank→ liquid reactor → solid filters → liquid filling equipment
How long does it take for liquid fertilizer fermentation?
Commonly, the time for cow manure liquid fertilizer fermentation is depended on method employment.
- For makes use of enzymes to decompose cow manure slurry liquid, the anaerobic fermentation, it needs only 3-7 days.
- As for aerobic fermentation with bacterial hydrolysis, it usually take you 15-25 days.
