Problems solved by technology

Disadvantages, the oil stays at high temperature for a long time, about 1-2 hours or more. In this case, the trans fatty acid rises by 0.7-0.8%, and the deacidification ability is weak, so the oil must be neutralized by alkali refining in the early stage to reduce the acid value
Aiming at the common problems of high deodorization temperature and long deodorization time in the prior art, the trans fatty acid in the deodorized oil is higher

Embodiment 1

[0030] The deodorization equipment used in the deodorization process will be further described below in conjunction with the accompanying drawings.

[0031] Such as figure 1 and figure 2 As shown, the deodorization equipment used for the deodorization process includes a plate tower, 1# deacidification tower and 2# deacidification tower, the top of the 1# deacidification tower and 2# deacidification tower is provided with a vacuum pipe port, and the deacidification tower The upper and lower ends of the tank are respectively provided with an oil inlet and an oil outlet, a liquid foam trap is installed on the inner wall of the tower between the vacuum pipe port and the oil inlet, and a rain distributor is installed on the inner wall of the tower at the lower end of the oil inlet. The middle and lower parts of the tower body of the deacidification tower are successively arranged as a packed tower and a distillation tower. The middle part of the packed tower is provided with anti...

Embodiment 2

[0034] On the basis of Example 1, different from Example 1, such as image 3As shown in the deodorization equipment used in the deodorization process, the liquid foam trap is arranged along the inner wall of the deacidification tower, which is formed by several layers of liquid foam boards arranged in parallel and at equal intervals, and each layer of liquid foam boards is arranged in a wavy Z-shape The extension plate and the liquid foam plate are provided with micropores at equal intervals. The liquid foam at the top of the deacidification tower is continuously collected as droplets under the action of the liquid foam plate, and flows along the inner wall of the tower into the packed tower. The filler adsorption in the deodorization tower can adjust the number of plates of vegetable oil passing through the liquid foam plate in the deodorization tower, adjust the deodorization time, moderately refine the vegetable oil, reduce the use of steam and the generation of trans fatty ...

Embodiment 3

[0036] On the basis of Example 1, different from Example 1, such as Figure 4 As shown in the deodorization equipment used for the deodorization process, the rain distributor includes an upper support plate and a lower support plate arranged in parallel along the inner wall of the deacidification tower, and funnels are arranged longitudinally at equal intervals between the upper and lower support plates. , The lower support plate and the side wall of the funnel are provided with hollow holes at equal intervals. The funnel is an integrated bullet-shaped structure connected by a hollow cylinder at the upper end and an inverted hollow cone at the lower end. The material components are placed on the upper support plate. Tiling on the top, it flows down along the inner wall of the funnel through the hollow hole on the upper support plate. During the process of flowing down, part of the water overflows through the hollow hole on the inner wall of the funnel, and flows down along the ...

Abstract

The invention discloses a low-temperature deodorization and high-temperature deacidification process capable of inhibiting trans-fatty acid of peanut oil. The process specifically comprises the following steps: (1) degumming; (2) de-coloring; (3) carrying out low-temperature deodorization; (4) carrying out high-temperature deacidification. A packing tower is additionally arranged behind a plate tower of a deodorization and deacidification process, and an alkali refining neutralization reaction section is removed; oil is uniformly distributed in a thin film form and a manner of directly adding saturated steam from the bottom is adopted to effectively remove undesirable odor; high-temperature time of an oil product is shortened; two sets of packing deacidification towers are additionally arranged, wherein the temperature of the #1 deacidification tower is controlled to be 260 DEG C and is used for instantly distilling to remove a large part of acid value, and the temperature of the #2 deacidification tower is controlled to be 265 DEG C and is used for removing the acid value in the oil again, so that the acid value of finished-product oil is reasonably controlled; furthermore, the time of staying at a high-temperature section of the oil is short, the content of the trans-fatty acid is only increased by 0.2 percent to 0.3 percent and the acid value can be controlled to be about 0.1; the alkali refining neutralization section is removed so that the loss of neutral oil is reduced and the yield is improved; the consumption is reduced by about 0.03 percent to 0.05 percent by one acid value; meanwhile, a plasticizer and the acid value in the oil product can be effectively removed.

Description

technical field [0001] The invention belongs to the technical field of deodorization technology, and in particular relates to a technology for suppressing low-temperature deodorization and high-temperature deacidification of peanut oil trans fatty acid. Background technique [0002] Because peanut oil plays a certain health care function on human health and taste mediation and human blood, soft tissues and organs, it is an ideal table oil. Trans fatty acids refer to fatty acids that have a double bond in the trans configuration. Commonly found in ruminant dairy products and margarine and other products. Trans fatty acids can increase the content of low-density lipoprotein and increase the risk of cardiovascular and cerebrovascular diseases. Trans fatty acids are also related to breast cancer. After 2003, many European and American countries required labeling the content of trans fatty acids in products. The WHO / FAO Expert Committee on "Diet, Nutrition and Prevention of Chr...
