Pressure: Up to 6 bar (87 PSI)

Temperature: Up to 200°C (392°F)

Drum Speed: <2 RPM — slow rotation minimizes mechanical wear

Drive: Large industrial drive motor, skid-mounted base frame

Enclosure: Fully gas-tight, pressure-sealed housing — suitable for hazardous solvent applications

Filter Area: unknown

Includes: Feed vessel with pump, top-mounted process nozzle array

Supports multi-stage cake washing, solvent exchange, steaming, extraction, and compressed gas cake drying, all in a single continuous pass. Gas-tight containment makes this unit well-suited for ethanol-based cannabis and hemp processing, as well as pharma and fine chemical applications. Rarely available on the secondary market at this scale.
