US Patent 7975854 Rotary fan press

A system (10) for extracting liquid from a mass comprising a portable platform (12) having an upper surface (14), a system mass input (16), a polymer feeding and blending system (18) on the upper surface (14), a liquid extraction assembly (40) on the upper surface (14), and piping (22) having a first section (24) between the system mass input (16) and the polymer feeding and blending system (18), and a second section (26) between the polymer feeding and blending system (18) and the liquid extraction assembly (40). The system is configured to have mass inputted into the system mass input (16), transport the mass to the polymer feeding and blending system (18) through the first section (24) of the piping, inject polymer into the mass in the polymer feeding and blending system (18), and transport the mass from the polymer feeding and blending system (18) to the liquid extraction assembly (40). Pressure from the mass forced into the liquid extraction assembly (18) forces liquid in the mass to exit the mass.
