Sunflower seed oil has high content wax,so sunflower seed oil has high melting point and freezing point,in low temperature ,the oil will become thickening ,even freeze,because of this ,the sunflower seed oil transit trade is limited.so it is necessary to improve the high value added liquid sunflower seed oil and solid wax fat.
Dewax adopts the dry type fractionation, crystallization and crystal growing process in the same tank , the interior of the variable frequency mixing device for crystallization, can achieve very good heat transfer, ensure material mixing; By using multi-level coil in the form of cooling, ventilation with cooling medium plate tube, the crystallization with good effect, the key is that heat transfer area, heat transfer coefficient, stirring speed, the control of parameters, avoid grain loose crystals dissolve back to temperature filter cake hardness could not be enough bread discharge, high residual oil filter cake of the phenomenon .
