Working Principle

Strip Oil PressBased on the physical pressing principle of “screw extrusion + strip chamber filtration,” its core structure consists of a spiral shaft and a strip chamber (composed of multiple parallel rectangular strips with fixed narrow gaps between them). During operation, pre-treated oilseed (cleaned of impurities and dried/roasted) enters the chamber from the feed inlet. The high-speed rotation of the spiral shaft propels the oilseed toward the cake outlet. The chamber gradually shrinks, creating a sustained high pressure (up to 25-50 MPa), disrupting the oilseed cell structure and releasing the oil. The pressure forces the released oil to filter through the narrow gaps in the strip chamber (typically 0.05-0.2 mm) and flow out as crude oil. The remaining oilseed residue (cake) is discharged from the cake outlet, completing the “oil-residue separation.” The entire process uses no chemical additives; oil extraction is achieved solely through physical extrusion and mechanical filtration.

Advantages
