Main Process of Oil Seeds Oil Pressing Production Line
Cleaning : In order to make good quality of edible oil and oil cake, before pressing , the impurities need to be removed out of oil seeds. Generally speaking, in oilseeds press workshop, vibratory cleaning sieve , de-stonner and permanent magnet drum are always used to clean the impurities in oil seeds, such as crop stalk, stone, magnetic metal, dust and other impurities which will influence oil quality, also in order to protect machine and make a clean working condition in workshop.
Crushing: After cleaning,in order to make the oil seeds granularity smaller and adjust the oil cake thickness, oil seeds shall be crushed into smaller pieces by crusher, thus creating a good condition for oil extraction.
Cooker: The purpose of cooking is to adjust the moisture of oil seeds, thus make oil getting out easily. The purpose of cooking is to make the protein of oil seeds cell wall degenerated and then aggregated because of heated, increase the permeability of cell wall, and decrease the viscosity of oil, thus make oil come out easily, to make small oil drops into big oil drops.
Pressing: The advantage of using press method to make oil is that, the support equipment is less, it is suitable for various oil seeds, such as sunflower, soybean, groundnut, sesame, rapeseed , sesame, niger seed and so on. The production line is very flexible, the oil quality is pretty good with light color and good flavor.
Filtering: After getting crude oil from press process, there are some oil residue in it, it should be filtered by filter in order to get clean crude oil. After this process, clean crude oil can be pumped in to crude oil tank directly for storage.
