The seaweed dewatering screw press is a purpose-built mechanical device designed to efficiently separate water from wet seaweed, significantly reducing its moisture content for downstream processing. Operating through a continuous spiral rotation, the press applies controlled pressure to compress the seaweed, extracting liquid while preserving the structural integrity of the biomass. This technology is pivotal in industries like aquaculture, bioenergy, and food production, where dewatered seaweed is used for biofuel feedstock, animal feed, fertilizers, or high-value compounds extraction. Its compact design, energy efficiency, and ability to handle high volumes make it a sustainable solution for scaling up seaweed utilization while minimizing waste and operational costs.
