Cottonseed Oil Dewaxing Equipment

Dewaxing is an important part of improving edible oil quality. The presence of waxy will affects palatability of oils and fats, so, the main purpose of the dewaxing is to improve the palatability of oils and fats, and to improve oils and fats' sensory properties such as transparency and brightness. To different oils, their wax contents are different, and to the following oils (such as: Corn oil, rice bran oil, sunflower oil, cottonseed oil, etc. ), dewaxing is almost necessary.

Although there are many methods of dewaxing, such as: Freeze-crystallization method, surfactant method, cold polymerized agent method, an electrostatic method, and neutralization winterization method. At present, industrial production basically adopt freezing crystallization, at the same time, because of the different nature of the different oil crystals, the crystallization rate, temperature, the crystal raising time and filtration ways have great difference.
