Problems and treatment methods of oil press in the process of pressing soybean
When using spiral oil press to press soybean oil, no matter cold or hot pressing, due to improper operation or oil water content adjustment is not suitable, there will be different problems.
1, when pressing slag phenomenon, screw oil press, when pressing oil, if there is a small amount of slag phenomenon, also belongs to the normal phenomenon (slag allowed up to 5*). If the amount of slag running is large, it needs to be adjusted. From the perspective of oil, improper water content of oil, too dry or too wet, will occur slag phenomenon, oil is too wet, strip row run check as sheet, cake is soft hand into a group, there is white foam in the flow of oil. If the oil is too dry, the strip run-off slag is powdery, the cake is white into powder, the oil flow is not smooth, and the oil discharge gap in the press bore should be less. That is, when the bar is installed, it should be tighter. The last bar should be hit by hand hammer. The pressing wire mother of the 100 type oil press should be tightened.
2. When pressing soybeans, oil return phenomenon occurs: that is, there is oil in the hopper. For pressed soybeans, oil return is rare, because oil return is a phenomenon that occurs easily when pressing oil with higher oil content. The strip clearance is too small: (that is, the tight on the strip), the cushion should be used to adjust the strip clearance. If the 100 type oil press is used, in addition to adjusting the strip clearance, it should also relax the pressing of the silk mother and increase the oil clearance of the park drain.
3, the cake is not not good, or not out of the cake, also do not feed: oil press does not feed and not out of the cake phenomenon, mainly is the new machine at the beginning of the time, without run-in, improper use caused by (sometimes hopper blockage caused by the material screw pull leaves turn over and do not feed), when the oil water content should be adjusted. If it does not belong to the problem of water, the new machine should be operated in strict accordance with the instructions, should slowly control the feed, standby temperature rises to more than 80 degrees before entering the normal press.
