Our oil press machines can process a great many plant seed such as peanut, soybean, sunflower seeds, sesame seed, cottonseed, rapeseeds, corn germ, coconut, palm kernel, jatropha seed, hemp seed etc. Structure of the Oil press machine Screw type oil press machine is mainly composed of feeder, gearbox, pressing cage, screw shaft and machine stand etc. Pressing chamber is the key part of the machinery which including pressing cage and a screw shaft rotating in the cage. You can also equip the expeller with motor, diesel engine or electrical control cabinet as you like. An electric cabinet can help control the whole working procedure How Does Oil press machine Work? A screw type oil making machine that presses oil seeds through a caged barrel-like cavity. Raw materials enter one side of the press and waste products exit the other side. The machine uses friction and continuous pressure from the screw drives to move and compress the seed material. The oil seeps through small openings that do not allow seed fiber solids to pass through. Afterward, the pressed seeds are formed into a hardened cake, which is removed from the machine.
1 . High oil yield--Compared with old-fashioned equipment, the normal oil yield can be 2 to 3 percentage points higher, and the average peanut oil per processing can be 2-6 kg more. There is less than 6% oil in the cake;
2 . Energy saving - the same output reduces electric power by 40%.
3 . Labor saving - the same output can save 60% of labor, 1 to 2 people can organize it.
4 . Wide range of uses - one machine can squeeze more than 30 kinds of oil crops such as peanuts, flax, sesame, rapeseed, oil sunflower, cottonseed, soybean.
5 . Pure oil--vacuum filtration residue to ensure the purity of oil, in line with health and quarantine standards.
6:The thickness of cake can be adjusted when machine stops running
