6YL-80 type cold and hot amphibious screw press machine is a new research improvement product , It can use to press soybean peanut sesame sunflower seed rapeseed cotton seed flaxseed corn germ and so on .  Most of the common oil materials are suitable for this machine .  The machine adopt infrared heating automatic temperature control and elaborate filter . The machine press the material in muti-stage , all the oil will get out of the material in the first pressing .  Raw material after the machine process will be pure oil  which can be eaten directly .  This machine suitable for small and mini oil factory ,  you can process the raw material on the scene , and sell the fresh pure oil timely .  Can also be material processing .  Easy to operate and high efficient .

Working principle:

When Oil mill working, processed oil material come from the hopper into the pressing chamber.  Due to material embryo in oil press chamber is in the motion state , under the  high pressure condition in squeeze chamber , there is great frictional resistance between pressing chamber Embryo and squeezer. There is friction between embryo micro material, resulting in relative motion.  On the other hand , because the diameter of squeezer screw thread  root circle is gradually increases, screw pitch is dwindling, So when squeezer is rotated,screw thread push material embryo , material embryo move forward and flip outward , meanwhile the material embryo near the the screw thread surface move together with squeezing axle .

So the movement of every material embryo particles in the pressing chamber is not at a constant velocity and in same direction .  Quantity of heat produced by friction meets the necessary need of oil process operation .  Make material in the embryo protein denaturation, destroyed the colloid, increased the plastic, reduce the oil viscosity, make it easy for oil to get out , so increase the oil yield of spiral oil press , oil flow out from the circular aperture and a row of gap .
