When the screw press oil extraction troubleshooting of the poor oil: (1) pressing of the seam is blocked diesel oil, mince or cage bars installed too tightly. You should remove oil sludge Unqualified, or re-adjust the tightness of the cage bars. If there is oil remaining inside the hopper should stop cutting, with cake and slowly press the oil out of the spiral Which is good, can continue to work. Oil can also be discharged from the discharge port, re-pressing bore dismantling parts, then start pressing. High (2) fuel oil content, but the cake is too thin so that oil can not be squeezed into the bore and discharged from the gap, in the hopper. At this point should be pressed high oil content oilseeds operation, to be thicker cake, on the contrary should be thinner. Multifunction press with the traditional press multifunctional contrast press has automated processes, the use of automatic humidity control technology and high-voltage vacuum hot pressing screw press filtration system, is currently on the market is more advanced oil extraction machinery. The aircraft a virgin net, saving time and labor screw press manufacturers, high oil factory direct screw press, equipped with small power, pure oil, a machine can sesame, peanut, rapeseed, soybean , sunflower, Hu and other 20 kinds of oil were grinding oil processing. Shortcomings of the traditional press methods: Original Square, poorly equipped, heavy operation, large area, high energy consumption, the oil is low, and poor sanitation. Multifunction Advantage press comparison: advanced design, reliable performance, simple operation, easy maintenance.
