Multi-stage deodorization device for vegetable oil processing

Abstract

The invention discloses a multi-stage deodorization device for vegetable oil processing, and belongs to the technical field of vegetable oil deodorization. The multi-stage deodorization device comprises a tower body; the tower body is respectively provided with a first bin body, a second bin body and a third bin body from top to bottom, one side of the first bin body is connected with an oil inlet, one side of the second bin body and one side of the third bin body are respectively connected with a steam inlet, and the bottom of the first bin body, the top and the bottom of the second bin bodyand the top of the third bin body are respectively welded with a first flange plate. The first bin body, the second bin body and the third bin body are detachably connected; a plurality of groups of coil pipes are arranged in a cavity; the inner wall of the cavity is heated by circulating hot fluid using a water heater; a stable temperature is maintained, the auxiliary deodorization operation effect is better, a deodorization filler is arranged in the first bin body, the second bin body and the third bin body, an oil body flows down from top to bottom, steam flows back from bottom to top, theoil body is subjected to multiple times of steam mixing, and the effect of removing odor small molecules of the oil body is better.

Description

Technical field [0001] The invention relates to the technical field of vegetable oil deodorization, in particular to a multi-stage deodorization device for vegetable oil processing. Background technique [0002] Deodorization means that various vegetable oils have their own unique flavors and tastes. After deacidification and decolorization, there will be traces of aldehydes, ketones, low-molecular fatty acids, white clay, and residual solvent odors. Remove these In the process of bad odor, the commonly used deodorization methods include vacuum stripping, gas blowing, hydrogenation, etc. Vacuum stripping has stable vacuum and low steam consumption, so it is widely used in vegetable oil deodorization technology. [0003] The existing vegetable oil in the deodorization tower uses a heat-conducting furnace to heat the heat-conducting oil for heating operation. With the influence of the pressure of the inner wall of the tower, there may be uneven temperature in the tower, which may aff...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the heating operation of vegetable oil by heating the heat-conducting oil in a heat-conducting furnace, with the influence of the pressure on the inner wall of the tower, there may be uneven temperature in the tower, which may damage the heat-sensitive pigment of the oil and affect the processing result , and the old-fashioned deodorization device has a large amount of steam, insufficient contact with oil, and low distillation deodorization efficiency. A multi-stage deodorization device for vegetable oil processing is provided.
