The working principle of a biomass dewatering machine involves the removal of moisture content from organic materials, such as agricultural residues, food waste, or sewage sludge, by mechanical means. These machines are essential in biomass processing industries, as they reduce the moisture content of biomass materials, making them suitable for further processing or utilization. There are several types of biomass dewatering machines, including screw presses, belt presses, and centrifuges, each with its unique working mechanism.

1. Screw Press Biomass Dewatering Machine:

Screw press dewatering machines consist of a rotating screw inside a cylindrical screen. The wet biomass material is fed into the machine, and as the screw rotates, it pushes the material against the screen. The pressure created by the rotating screw forces the water through the screen openings, separating it from the biomass. The dewatered biomass is then discharged from the machine, while the separated water is collected and removed.

2. Belt Press Biomass Dewatering Machine:

Belt press dewatering machines use a series of rollers and belts to squeeze out the water from biomass materials. The wet biomass is fed onto a porous belt, which passes through a series of rollers. These rollers apply pressure on the material, squeezing out the water. As the belt moves through the rollers, the dewatered biomass is collected, and the separated water drains away.

Benefits of Biomass Dewatering Machines:

Improved Combustion Efficiency: Dewatered biomass has a higher calorific value and burns more efficiently than wet biomass.

Reduced Transportation Costs: Removing water from biomass reduces its weight, leading to lower transportation costs.

Easier Storage and Handling: Dewatered biomass is easier to store and handle compared to wet materials.

Environmentally Friendly: Dewatering reduces the volume of biomass, making it more environmentally friendly to dispose of or process further.

In summary, biomass dewatering machines work by applying mechanical pressure or centrifugal force to separate water from wet biomass materials, resulting in dewatered biomass that can be used for various applications, including energy production and organic fertilizer manufacturing.
