Deodorization process using a soft tower, flexible object is achieved by the column system "first stripped rear holder" principle, carried out first in a packed stripping column to remove free fatty acids and other volatiles, "odor" material, and as far as possible reduce the loss of vitamin E and the possibility of the formation of trans fatty acids. Use a soft tower can deodorization / deacidification process to achieve a lower temperature, shorter treatment time, its use can not only reduce production costs, but also help to suppress the generation of trans fatty acids and vitamin E to keep remaining amount.
Deodorization process is generally recommended operating temperature is about 230
. Stripping section and a completely separate tray to prevent the generation of free radicals and pigmentation. Free radicals are generated and the reasons for the deterioration of the flavor oils become darker in color, in addition to the presence of free fatty acids can be induced pigmentation and a new generation of free fatty acids, but the soft deodorization tower / deacidification system in the stripping operation can be completed 5min Accordingly, the oil resulting pale color, while the thin inner tray oil, a short retention time, can suppress the generation of trans fatty acids.

When the degree of vacuum in certain circumstances, a different amount of steam stripping the distillate will capture vitamin E have different effects. When the small amount of steam stripping, the remaining amount of vitamin E in the oil and more inevitable. Deodorization process column system due to the use of soft, do not have to scroll through the use of steam reservoir, a low pressure drop which is stripped, so you can use less amount of steam stripping treatment, will help improve the remaining amount of vitamin E in the oil, the power consumption low.
