摘要： The invention relates to the field of vegetable oil refining technologies, more particularly, to the technology of wax removal from vegetable oils by freezing out or winterization, and can be used for the improvement of the existing and the development of new technologies. Separated used filtering product regeneration step is added to the method of wax removal from vegetable oils the working cycle of which comprises winterization of the vegetable oil with the addition of auxiliary filtering powders, low temperature exposure of the oil and separation of the used filtering powder with the wax containing residue from the refined vegetable oil. To this end the used filtering powder is mixed with the additionally introduced fatty product to a paste condition, said paste is heated with stirring to the melting point of all the waxed and the resultant mixture is separated by centrifugation to obtain regenerated dry filtering powder and a wax containing fatty product. The regenerated filtering powder can be multiply recycled as the auxiliary filtering powder in the subsequent working cycles comprising winterization of the new vegetable oil portions wherein each working cycle is followed by regeneration of the used filtering powder.
