Usually oil press machine can be divided into screw oil press machine, new type hydraulic oil press machine, household small type oil press machine, automatic oil press machine, etc. In China, most popular raw materials are peanut, soybean, rapeseed, cottonseed, sunflower seeds, sesame, olitea camellia seed, maize germ,these raw materials must be roasted with peanut roaster machine.our cold oil extraction machine can be used in peanut ,soybean, sunflower, vegetable seeds, coconut, olive ,etc and all kinds of plants for edible oil. The oil press can both hot pressing and cold pressing.
But overseas, usually coconut, olive, oil palm fruit, avocado, etc are popular. The first production process: raw material-----frying-----pressing-----filtering-----pure oil
The second production process: raw materials-----crushing-----steaming-----pressing----
filtering-----pure oil
The main composition of this screw oil press machine are electrical cabinet, gear-box (axle and gear), principal axis (key part), squeezing chamber, heating ring, etc.
Cold oil extraction machine features
1)Cold oil extraction machine is made of high quality steel, wear-resistant and easy to clean.
2)With the properly designed pressing chamber, the increased pressure in the chamber highly improves working efficiency.
3) Alloy steel is treated by carburization for improving its surface hardness and wear resistance.
4)Squeezing once with 3rd grade.
