In modern livestock farming, cow dung is a valuable organic resource—but only when properly managed. Fresh cow manure contains over 75% moisture, making it heavy, difficult to transport, and unsuitable for direct composting or pelletizing. This is where a cow dung dehydrator (also known as a manure dewatering machine) becomes indispensable.
Gofine Machine provide advanced cow dung dewatering equipment that helps farmers, biogas plants, and fertilizer producers efficiently separate solids from liquids, reduce waste volume, and prepare organic materials for further processing.
What Is a Cow Dung Dehydrator?
A cow dung dehydrator is a type of solid-liquid separator specifically designed for livestock waste treatment. It separates raw manure into two fractions:
- Solid manure: Ideal for composting or organic fertilizer production
- Liquid effluent: Can be used for biogas, irrigation, or further treatment
This cow manure separator plays a vital role in farm waste recycling and organic fertilizer manufacturing, helping reduce odor, pollution, and pathogens.
How Does the Cow Dung Dehydrator Work?
The working principle of a cow dung dewatering machine involves several mechanical and hydraulic processes:
Step 1: Feeding
Fresh cow manure (often mixed with urine or water) is pumped into the input port of the machine using a screw pump or submersible slurry pump.
Step 2: Separation
Inside the machine, a screw shaft rotates continuously within a cylindrical screen (mesh filter).
As the manure moves forward under pressure, the liquid phase passes through the screen, while the solid phase is pushed forward.
Step 3: Liquid Discharge
The filtered liquid (containing dissolved nutrients) is discharged through a pipe. This liquid can be reused for biogas fermentation, flushing, or fertigation.
Step 4: Solid Output
The dehydrated cow dung solids are extruded from the outlet and fall into a collection area. The moisture content is reduced to 30–40%, making it suitable for:
