From Seed to Seed Oil

screw oil pressA 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.
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.
When the press operation, the processed oil from the hopper into a good squeeze bore. Pressed by the screw turn make the material to keep the embryos in advance, be pressed. Since the parison in the press bore is squeezed in the state of motion, pressing bore under high pressure conditions, resulting in a lot of friction between the material and the pressing screw embryos, embryos and virgin material bore, thus make friction, resulting in relative movement between the micro-parison material. On the other hand, due to the pressing screw root diameter is gradually thickening Park pitch is gradually reduced, so that when the pressing screw is rotated, the threaded hard parison that is able to move forward, but also to turn outward, and close to pressing screw thread as the surface layer material further pressing axis. Such virgin bore in each parison particle velocity is not the same direction, but also exist between particles relative motion. Heat generated by the friction but also to meet the oil extraction process operation necessary calories, help to promote parison thermal denaturation of proteins, damage colloid, increased plasticity, but also reduces the stickiness and some oil to easily precipitate, thus improve the oil yield of the press, so that there is oil squeezed out of feed and discharge slit strip and exhaust flow from the slit garden.

Advantages of Screw Oil Press
Oil rate - compared to the old equipment, the oil rate can be higher than the normal 2-3 percent per hundred pounds of peanuts processed an average of 2-6 pounds more, the annual economic benefits are substantial.
Energy - the same electrical power output reduced by 40%, with an average savings of 6 kWh per hour, the production can save 30 yuan electricity.
Labor - equivalent yield savings of 60% of the labor force, 1-2 people can organize production, the effectiveness of labor savings of about 40 million.
Versatile - a machine can be pressed peanut, flax, sesame, rapeseed, sunflower, cottonseed, soybeans and other 30 kinds of oil crops. Multi-stage press, a virgin net.

Pure oil - vacuum filtration residue to protect the oil clean, hygienic and quarantine standards.
Small footprint - 10-20 square meters for an oil mill will be able to meet.
