Introduction of Screw Oil Press

Screw oil press is advanced oil extracting machinery, characterized by its high oil yield with good quality, simple design and convenient operation. The screw oil press machine is for squeezing various oil materials, such as peanuts, rapeseeds, cotton seeds, sunflower seeds and soybeans etc. This type is semiautomatic expeller. Automatic screw oil expeller is supplied too.

Screw Oil Expeller Application

Screw oil presses are more suitable for medium-sized and small-sized grain and cooking oil processing factories or specialized households. They can press particle oil materials and powder oil materials, such as rapeseeds, cotton seeds, soybeans peanuts and sesame etc.

Screw Oil Presser Working Principle

The screw oil press mainly uses the change of pressing screw pitch size and screw thread depth to reduce the volume between screw pitch and pressing chamber, the oil materials get stronger pressure gradually, thus the oil can be squeezed out of the oil materials. Meanwhile, the high pressure in the chamber and the strong friction generates high temperature, which can improve the oil yield.

how does screw oil expeller work and its structure


▲The temperature of oil manufacture room should keep between 15℃ to 20℃. If the temperature is too low, it will affect the oil yield and oil quality.
▲Before pressing, the oil materials’ moisture content should be appropriate: peanuts with 8%—11%, soybeans with 5%—8%, cotton seeds with 4%—6%, rapeseeds with 6%—8%.
▲After running for three to four months, the screw oil press needs a maintenance. Lubricate the machine parts with machine oil at regular intervals.
