Screw Press for Slurry Seaweed
Function:
Designed for continuous dewatering of seaweed slurry, reducing moisture content before drying or extraction. The screw press separates liquid from fibrous biomass, producing a concentrated, semi-solid seaweed cake with reduced water load.
Operation:
Seaweed slurry is fed into the press chamber, where a rotating screw gradually compresses the material. The pressure increases along the screw length, forcing water out through the perforated screen while retaining solids. The adjustable back-pressure cone at the outlet ensures stable dryness of the discharged cake.
Main Process Steps:
- Slurry feeding by pump or conveyor
- Progressive compression by screw shaft
- Filtration through perforated screen
- Discharge of concentrated seaweed cake
- Collection of filtrate water for reuse or disposal
