Wet Extruder HP162

The oil material is squeezed, heated, sheared and rubbed in the extruding cavity of the machine, and mixed, steamed, gelatinized by injected direct steam, the pressure in extruding cavity will reach 1.4-4.0 MPa, the temperature reaches 110-120℃, at the die head outlet suddenly reduce to normal pressure and temperature, the steam vaporizes abruptly, oil in seed cell run outside then, and extruded material with numberless minus holes and cracks got.And because of such extruding effects, the permeating of solvent through cells and permeating of oil out from cells both become easier, so the extraction and desolventizing process both get more efficient, the unit weight of material is raised about 30% , so the production capacity of extractor is also raised.

The stay period of material in the extruding machine is less than 30 seconds, so the damage of the content of material is little, which helps the protection of the quality of material.
