Deacidification and deodorizaiton tower
Continuous deacidification and deodorization:Under the vacuum condition and high temperature (250-260℃).
The deodorization system can remove fatty acid and odor components high efficiently and makes oil good flavor.
Meanwhile, it has the advantage of lowering steam consumption and avoid of the hydrolyzation of oil.
Deodorization process aims to remove the FFA and low molecular compounds in bleached oil. Entering into the
deodorization process,the flow of bleached oil is controlled by a flow controller,and the oil is heated to250-260℃
through a series of heat exchanger, then the temperature can reach to the condition of deodorizing.
When deodorizing, odor material in oil will be removed under the condition of high temperature and high vacuum.
Distilled fatty acid gas is discharged from the top of the deodorization tower,then collected by fatty acid catcher
thus, the environmental pollution will be reduced.
Feature
1,Main device of the deodorizaiton process, which can separated into tray type, feeding type, composition type,
collector, high temperature heat exchanger and so on systems;
2,stainless steel complete shut-off structure, long-life span, good oil quality;
3,low consumption, shorter time to deodorizaiton, and with good decolorizaiton effect.

Advantage
1.It adopts stainless steel structured packing, which has increased the surface area of gas-liquid contact, gas-liquid
transfers well,reduced the oil in the Tower residence time,effectively reducing trans fatty acids produced,guarantees
the quality of refined oil.
2.High temperature can decompose substances such as oil pigments, hydrogen peroxide, easy to improve the smell
of grease, taste and color.
3.A huge oil surface area,increases gas-liquid mass transfer efficiency; saves steam stripping and consumption in
vacuum system (saving steam 50%-70%).
4.Deodorization process can achieve physical removal of acid,no waste water emissions,and efficient environmental
protection.
5.Compact structure,small area covered,low cost of construction and installation.
