Product Details of Hydraulic Oil Press and Screw Oil Press

Hydraulic Press uses a completely physical oil extraction method with no heat created during the whole progress, there is no destruction of the organic constituents of the oilseeds, so the oil is good quality and less impurity, it is suitable for oilseeds with high oil content (sesame seeds, almonds, pine nut, peanut, walnut and some animal oil, etc.) and the raw material that need to be processed with cold - pressing method (chemical and pharmaceutical raw materials).

The waste created during the production progress has high re-use value and wide range of applications. Like the food processing enterprises who have the products like walnut powder, almond milk, peanuts, the waste can be processed and made into other product, there is a requirement of oil extraction rate which can be controlled by adjusting the pressure value of the oil press.
Oil extraction rate control is imposable for screw press, some organic constituents would be destructed due to the high temperature created by friction in the process. When the production is finished, the oil temperature is high and cooling treatment is needed. And when dealing with high oil content oilseeds, some waste would be pressed through the pressing ring and mixed with our product. The moisture content of the waste is only 1/5 compared to the hydraulic press, which would cause certain lost of the weight when selling the waste.
