The squeezing of wheat and wheat oil equipment operation process at low temperature
(1) using wheat wheat drying: to clean up when squeezed oil press equipment to avoid oil into wheat with some impurities.Before entering the sunflower oil press (http://www.sunflowermill.com) without removal of entrained mud, stem leaf and other sundry, they not only affect the quality of oil and cake, but also part of the adsorption grease, reduce the yield efficiency.If there is a sand, metal, hemp rope clamp etc sundry, more will cause wear parts, etc., induce production accident, influence the process effect.
Therefore, in order to ensure production run smoothly, must try to remove impurities, individual high moisture content of wheat grain, easy to shell, dry processing is also very necessary.
Clean up a lot of methods, specific according to the situation of impurities by different methods.If light contains impurities, such as grass, leaf, can adopt the method of air separation, with air blows away the impurities.If the impurity particles is lesser, can choose, to remove impurities.For some similar size, relative density and wheat impurities, if belong to the soil block, can friction in the machine, after reoccupy screening method to remove.If iron impurities, the electromagnet or permanent magnet line separation can be used.Clean up after the impurity content should be in the following.
(2) (being) heat treatment: heat treatment is one of the most important working procedure in the process of extracting oil.Including the green moist and heating, heat treatment on the production called steamed or Fried, steamed characterize called cooked after fire.Green after all heat treatment by squeezing called hot pressing, without heat treatment known as cold pressing.Wheat is mainly hot pressing.Heat treatment effect is good or bad on the smooth progress of the whole process of making oil yield efficiency and high and low and oil has a direct impact on the quality of seed cake....
