Description

TECHNICAL FIELD

[0001] The utility model relates to lutein production technical field especially to a production equipment for preparing high-purity lutein ester from marigold extract. BACKGROUND

[0002] Lutein is an oxygen-containing carotenoid, which is widely present in the flowers, leaves and fruits of plants. The petal of marigold has the highest lutein content. Recent researches show that the stability of free lutein is poor in vitro, and it is prone to oxidative degradation. The stability of lutein in the form of lutein ester is obviously better than that of free lutein. It is found that lutein ester is more easily absorbed by the human body. It can be converted into free lutein in the human body. Free lutein has the effects of antioxidant, free radical elimination, anticancer and reduction of cardiovascular disease incidence. It is also one of the main components of macular pigment in human eyes. It has significant effects in preventing and treating senile cataract and macular degeneration. Therefore, the development and application of lutein ester are of great significance.

[0003] For example, a utility model patent with the publication number CN212881152U and the name of a production equipment for preparing high-purity lutein ester from marigold extract includes a supercritical CO2 extraction tank. The supercritical CO2 extraction tank is provided with a marigold extract feeding port. The marigold extract can be extracted and purified. The supercritical CO2 extraction tank is connected to a stainless steel tank through a first conduit. A filter and a buffer valve are arranged on the first conduit. A motor is fixedly arranged on the top of the stainless steel tank. A rotating shaft is fixedly connected to the output end of the motor. A rotating blade is arranged on the rotating shaft. An ethyl acetate inlet and an anhydrous ethanol inlet are arranged on the top of the stainless steel tank. An electric heating jacket is arranged at the bottom of the stainless steel tank. The stainless steel tank is connected to a high-speed centrifuge through a second conduit. The high-speed centrifuge is connected to the top of the stainless steel tank through a third conduit and connected to a vacuum drying box through a fourth conduit. A filter screen is arranged on the third conduit and the fourth conduit. The raw materials used in the utility model are widely sourced, and the production cost is low. The solvent can be reused.
