Winterization of oil is a process of separating the higher melting point parts from oil like waxes by slowly cooling vegetable oils. The most common oil that is winterized is rice bran oil which has a high content of waxes, fatty acids, and lipids. Winterizing mainly consists in cooling these oils gradually and separating them at low temperature in special filters or by centrifugal separators. Our plants are designed for batch or semi-continuous process based on filtration pattern. Dewaxing is also known as winterization. Some oils are dewaxed before packing so as to remove waxes, which are dissolved in the oil. Most of the oils do not need dewaxing as they contain little or no waxes.
