With the improvement of living standards,consumption of the increasingly widespread application of pigment,but the pigment synthesis of a negative impact on health has also been recognized more and more,natural lutein's role in health care is receiving increasing attention,and explore a species extracted from marigold flowers of the process of high-purity lutein means higher production rates,high purity,safe drug-free lutein is the subject of the goal. To extracts of marigold flowers - lutein extract raw materials for the experiment,the temperature at 56℃water bath,by adding 90 mL ethanol mixing.To be a balance both inside and outside temperature,the slowly adding 20 g 45%aqueous solution of KOH.Hydrolysis of three hours.TLC detection of degree of hydrolysis>95%.Complete saponification after adding 300 mL 40℃hot water,stirring.25%acetic acid regulation of pH values between 6 to 7,centrifuge,disposable water phase.Washed three times,clarified filtrate color.Freeze-drying,high purity lutein crystals. Saponification reactor proposed is based on laboratory saponification process,in order to meet the requirements of the process reactor design professionals,learn from the mature conventional reactor design theory,according to the particular process of the saponification process has the following aspects of the design of innovation:1.The use of stainless steel mixing matrix leaves + welding wear-resistant layer structure, significantly avoid iron contamination.2.The use of hardened gear reducer mill,equipment life expectancy increased by 3~4 times. Reactor design,reference a lot of experience of the existing equipment,and finally in accordance with the requirements of the process,according to national standards selected.So as to shorten the manufacturing cycle,lower manufacturing costs,but also to facilitate future maintenance,repair.3.Pit dilute oil dry down and sealed to ensure that the output shaft of the reducer is not oil(with photos).Support shaft oil lubrication bearings,carbide mechanical seal to prevent leakage or wear and tear within the material of the reactor caused by pollution.4.Other ancillary equipment as far as possible the use of standard parts,greatly reducing the manufacturing cycle.Through the device in practice the use of basic design requirements to meet.
