Peanut Oil Extraction Process Technology
(1) clean and dry of peanut: peanut unavoidably with some impurities.If you don't clear peanut kernels in the midst of the earth and stem leaf of sundry, they not only affect the quality of oil and cake, and will be part of the adsorption grease, reduce the yield efficiency.If the catsup with sand, metal, hemp rope and other sundry, more will cause wear parts, etc., induce production accident, influence the process effect.Therefore, in order to ensure production run smoothly, we must try to remove impurities, individual high water content of kernels, 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 peanut 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.
