Palm oil is mainly manufactured in most equatorial belts of the world with Indonesia and Malaysia being the world leading producers. This oil is not edible in its initial state and therefore the crude palm oil fractionation processing is very important.
Huatai palm oil fractionation process mainly include crystallization and palm oil fliter.Palm oil fractionation goes through the control of palm oil cooling and crystallization to make separation of palm oil into low melting point liquid (soft fat) and high melting solid (sterin).
The crystallization process follows in the crude palm oil refinery process. This process involves the removal of high-melting glycerides that would cause the liquid oils to become viscous and cloudy at room temperatures.
There are three most important factors: time, agitation and temperature. Low temperatures will cause the components to separate due to supersaturation while formation of smaller crystals will be facilitated by agitation. With gradual decreases in temperatures, longer crystals will be formed with time.
