Equipment for reducing content of trans-fatty acids in corn oil and process of equipment

Abstract

The invention discloses equipment for reducing the content of trans-fatty acids in corn oil. The equipment includes a deodorization tower (18), a pre-deacidification tower located at the upper part ofthe deodorization tower, and a post-deacidification tower connected with the deodorization tower through a deodorization tower oil outlet pipe; the upper part of the pre-deacidification tower is provided with an oil inlet pipe, the interior of the pre-deacidification tower is provided with a stainless steel mesh, and a first partition plate is arranged between the pre-deacidification tower and the deodorization tower; a second partition plate is arranged in the deodorization tower, and a vertical liquid conveying tube, two oil receiving cups, and a vertical liquid conveying tube are sequentially arranged on the second partition plate, the vertical liquid conveying tubes are vertically connected to the second partition plate, and the upper end of each vertical liquid conveying tube communicates with one spray nozzle through one corresponding horizontal oil conveying tube; and a stainless steel mesh is installed in the post-deacidification tower, the lower part of the post-deacidification tower is provided with a third partition plate, and the bottommost part is provided with a deacidification tower oil outlet pipe. The invention also discloses a process for deacidification and deodorization by using the equipment. The equipment and process provided by the invention control the generation of the trans-fatty acids.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to equipment and a process for reducing the content of trans fatty acids in corn oil. Background technique [0002] Trans fatty acids, also known as trans fats, are ubiquitous in common fats or most oily foods in our daily life. The source of trans fatty acids is mainly due to the hydrogenation of vegetable oils, or the production of vegetable oils by heat and catalysts. The cis fatty acids in them will be converted into saturated fatty acids due to the high heating temperature, and at the same time Produces some trans fatty acids. Once the human body consumes excessive trans fatty acids, it may increase the cholesterol content in the blood, and the incidence of cardiovascular diseases will also increase; in addition, experiments have shown that trans fatty acids are likely to increase the viscosity and polymerization degree of human blood , compared with peopl...

Once the human body consumes excessive trans fatty acids, it may increase the cholesterol content in the blood, and the incidence of cardiovascular diseases will also increase; in addition, experiments have shown that trans fatty acids are likely to increase the viscosity and polymerization degree of human blood , compared with people who consume trans fatty acids with a low caloric ratio, the blood viscosity of people with a high caloric intake increases, so the latter also ha
