Our Oil Presser,screw oil pressmachine is a screw-driven oil making machine that used to extract oil from seeds and kernels for edible or biofuel purposes. 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 pressing machine:
Screw type oil machine is mainly composed of feeder, gearbox, pressing cage, screw shaft and machine stand etc. Pressing chamber is the keypart of the machinery which including pressing cage and a screw shaft rotating in the cage. You can also equip the expellerwith motor,diesel engine,orelectrical control cabinet as you like. An electric cabinet can help control the whole working procedure.
C. Working Principle:
The screw oil expeller utilizes the screw shaft that is set-up with different styles of screws and rotates when machine is running to push the material into chamber. Owing to the sprial helical pitch of screws becomes shorter and the sprial depth of screw. Becomes shallower, in the chamber the volumes between screws and pressing ring inner is smaller, pressure produced from curve saw -tooth of pressing ring inner, which oil is separated out. Oil releases from the gaps between bars and oil slots between pressing rings. Cookie release from the cookie release state.
