A kind of lutein ester extraction process

Abstract

The invention belongs to the technical field of effervescent tablet processing, and in particular relates to a lutein ester extraction process, which uses a lutein ester extraction device, and the lutein ester extraction device includes a workbench, a mixing mechanism and a filter Mechanism, the specific process of extracting lutein esters by using the above-mentioned lutein ester extraction device is as follows: the marigold flower grains are passed into the interior from the feeding port at the upper end of the mixing tank, and the temperature in the mixing tank is adjusted at Between 20 and 70°C; feed n-butane or acetone into the mixing tank to dissolve marigold flower grains, start the first motor, and make the mixing blades on the outside of the drive shaft stir the mixed solution for 0.5 to 5 hours. The invention enables the dissolving liquid to be intermittently transported in two directions, and cooperates with the intermittent start-stop mechanism to clean the filter screen during the process of filtering the dissolving liquid, reducing the accumulation of impurities on the filter screen, so as to ensure the smoothness of the filtering operation. steady progress.

Description

technical field [0001] The invention relates to the technical field of effervescent tablet processing, in particular to a lutein ester extraction process. Background technique [0002] In recent years, due to high work pressure and tense pace of life, people's study, work and entertainment are increasingly dependent on video display terminal equipment such as computers and TVs. They often use their eyes excessively and do not pay attention to eye maintenance, resulting in vision loss and even induced A variety of eye diseases have brought great harm to people's physical and mental health. Lutein ester effervescent tablets are also more and more popular at present. [0003] There are many extraction methods for lutein esters. Generally, we use the leaching method. The first step of the common leaching method is to dissolve marigold flower grains in n-butane or acetone, then stir and filter, and extract the filtrate for further extraction. However, the general extraction fil...

Problems solved by technology

[0003] There are many extraction methods for lutein esters. Generally, we use the leaching method. The first step of the common leaching method is to dissolve marigold flower grains in n-butane or acetone, then stir and filter, and extract the filtrate for further extraction. However, the general extraction filtrate is always operated separately by stirring and filtering, which will cause the following problems: 1. Stirring is mainly to dissolve the marigold flower grains evenly, so that a higher purity extract can be extracted. However, when stirring and filtering are operated separately, the dissolved solution of marigold flower grains will slowly precipitate at the moment the stirring is stopped, causing the problem of uneven dissolution; 2. When filtering, the dissolved solution is generally filtered through a fine filter. This will easily lead to clogging of the fine filter, resulting in slow filtration efficiency and uneven filtration.
