Oil demand of different pretreatment process
seed oil extraction is a kind of oil processing machinery, is the oil blank pretreated with extrusion method to extract vegetable oil machinery. As the spiral press press is a large pressure oil through pre press, pre press the blank after add press continue to press or by leaching extraction of oil. So the squeezing chamber volume change, the outlet end of the larger, production capacity is large. Oil function of continuous operation, low labor intensity, cake after oil thin and small, comprehensive utilization.
When we use press, often find that sometimes a certain amount of raw materials, squeezed oil is sometimes more and sometimes less.
So, how to make the press to keep a stable working state, and improve the oil press oil yield? Want to improve the oil yield is actually very simple, is to do the stock preprocessing procedure. The quality of pretreatment will directly affect the normal work of press and oil yield. Different fuel requirements pretreatment processes are different, including the following:
1 oil drying, selection. oil machine should be dried in the sun, Yang net, processing of the oil is generally contain some impurities, if wear not carefully cleaning will accelerate the internal parts of press press, reduce the rate of oil, will cause serious damage to oil press machine.
The 2 shelling, the shell oil such as cottonseed, peanut shell, can improve the efficiency of the press to oil press, improve productivity and yield of oil.
The 3 crushing flaking, Lee hung press does not pass through this program can press, especially rapeseed without flaking is not obviously affected, and the other oil by rolling after the embryo to improve throughput and yield of oil have great benefits.
4 the steaming and stir frying, steaming and stir frying is a most important link to improve the oil yield, even if the oil first wetting treatment, and then by the wok dry, finally press. Lee hung press although suitable for cold pressing, hot pressing but the productivity and yield of oil is higher than that of cold pressing, oil frying, should fire is moderate, the reactionary uniform, to prevent burning.
