Product Introduction

Combined Deacidification And Deodorization Tower

Combined deacidification and deodorization tower is suitable for the deacidification and deodorization of vegetable oil and it can produce high-quality edible oil.
This equipment is made of stainless steel and adopts pad technology. It has high rate of mass transfer. So it reduces the retention time of oil retained in the vessel and guarantees the oil quality and its nutrition value.

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.

The Main Structure Of Oil Deodorizing Tower

This equipment is composed of FFA catching section, stripping section and layer plate section.
There is filling in FFA catching section and vacuum system is connected on the top of this section;
The stripping section is composed of distribution plate,packing layer,collecting plate.
The layer plate section is high temperature decolorization section, each layer is equipped with direct steam nozzles and side exhaust pipe.

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.
