The deodorization tower is mainly used for oil deodorization. It is a kind of distiller used to remove odor in the distillate under high temperature and high vacuum. It is commonly used for distillation of heat sensitive materials or separation of substances and impurities with high boiling point under normal pressure. The deodorization tower is the main equipment for plant oil in production of cooking oil and salad oil. In addition, in the deodorization and distillation of oil, the boiling points of odor components and oil are different, even under the same temperature, the saturated vapor pressure of odor components is larger and the boiling point is lower, while the saturated vapor pressure of oil is smaller with higher boiling point. So the odor component is a low boiling point volatile substance, easy to be removed from the oil. Next, in the deodorization process, free fatty acids can be removed simultaneously, and the smoke point, the color and the stability of the oil can be improved.
 
Gas substances from the dewaxing oil from the winterization section will enter the deodorization section to remove the free fatty acids and unpleasant gas. All of this will be removed under the high vacuum circumsatnces by the deodorization tower. Using the to remove these substances by steam under high vacuum conditions. The removed fatty acid will be collected by the fatty acid trap and pumped into the receiving tank, this later will be used as vice products.
 
In order to save energy, the decolored oil will firstly heat ex-changed with the deodorization oil by heat ex-changer, and then heated to the deodorization temperature of about 235-236℃ by high pressure steam.
 
The water ring vacuum pump was adopted in the deodorization section vacuum system, the extracted odor in deodorizing vacuum will be trapped by the circulating water, thus to eliminate the odor pollution in deodorizing section.
