In palm oil mill plant the Palm Oil fractionation process work under slowly stirring and cool the oil to certain temperature in fixed time (technical security),and make waxy formed bigger crystallization,then separation exhalation,after filtering ,it separates the fluid oil and solid fat .After fractionation ,the oil will be clean after 5.5 hours in 0 ℃，but it also can keep the transparency and flowability in the refrigerator and improve the oil quality and appearance.
Our palm oil mill have the new technology of fractionation invented by our company adopt full automatic control, our product has advanced technology, stable quality.
Compare with the traditional fractionation technical of adding filter aid,the new one has characters as follows:
(1)Don't need to add any filter aid agent, the products are natural and green
(2)Easy to filter,the product oil has high yield
(3)Pure by-product edible wax,not contain filter aid agent and can use the edible wax production directly,no pollution
(4)High automaticity and can suit to large-scale commercial run
Crystallization technology in palm oil mill plant：
Crystallization technology in palm oil refining is mainly used for the separation and purification of oil in the specific high-value components such as oleic acid, linoleic acid and other unsaturated fatty acids, crystallization technology is mainly have two kinds：low-temperature crystallization and urea package.
Diaphragm filter used the filter box is the diaphragm box, that is, in the membrane press frame is covered with a very soft membrane, the diaphragm is fixed in the diaphragm box, through the hydraulic device filter cloth to press.
Diaphragm filter size, structure, the plate and frame filter press is composed of multiple filter plate and filter box arranged on the filter plate alternately.
Since the 1990s, people began to use diaphragm filter press, it can be efficient separation of grease, and has been very widely used.
