Introduction of vegetable oil dewaxing/winterising

August 26, 2016 15:56 Henan Doing Mechanical Equipment Co. Ltd is one of the leading company who is specialize in the vegetable oil press, vegetable oil extraction, vegetable oil refining and vegetable oil dewaxing/winterising machine for many years.
And for the vegetable oil dewaxing/winterising, not all crude vegetable oil requires this process, general, only sunflower, corn and rice bran vegetable oil is to be dewaxed/winterised before consumption as it contains high molecular weight wax. The wax makes the oil cloudy.
To obtain very clear quality of oil specially in cold conditions, vegetable oil needs to be dewaxed/winterised. If oils stored at low temperatures , waxes, high melting tri glycosides and certain gums may separate as solids from the oil. This leads to an undesirable cloudy appearance , and many consumers may mistakenly think the oil is spoiled.

The steps for the vegetable oil dewaxing/winterising process are as follows:
The oil is cooled in crystallisers and gradually the crystal formation takes place. Here filter aid is also added.
The oil is then transferred to a maturator where the crystals are allowed to grow. The oil is continuously cooled by the help of glycol water flowing through the coils.
Finally the oil is filtered on hermetic pressure leaf filters to remove the waxes.

The major advantages of this vegetable oil dewaxing/winterising process is :
Single plant can be used for dewaxing and winterising.
Optimum care is taken to maintain the formed crystals till filtration.
Minimum filter aid consumption.
