Screw oil press is advanced oil processing machinery, characterized by its high oil yield with good quality, simple design and convenient operation. The screw oil press machine can be used for squeezing various raw materials, such as peanuts, rape seeds, cotton seeds, sunflower seeds and soy beans etc. Screw Oil Press Features ¡ôReasonable and simple design; ¡ôSmall size, covering little space; ¡ôSaving labor and electricity; ¡ôEasy operation and convenient maintenance Screw Oil Press 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, soy beans, peanuts and sesames etc. Screw Oil Press 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. Notice ¡øThe temperature of oil manufacture room should keeps between 15¡æ to 20¡æ. If the temperature is too low, it will affect the oil yield and oil quality. ¡øBefore pressing, the oil materials' moisture content should be appropriate: peanuts with 8%¡ª11%, soy beans with 5%¡ª8%, cotton seeds with 4%¡ª6%, rapeseeds with 6%¡ª8%. ¡øAfter running for three to four months, the screw oil press should be for a maintenance. Lubricate the machine parts with machine oil at regular intervals.
