Embodiment Construction
[0031] In the following, the present invention will be further described as an embodiment in combination with the aforementioned technical solutions and accompanying drawings.
[0032] The production raw material is the dried marigold flower granules after treatment, and the extraction solvent adopted is n-butane. Adopt the same process and equipment as the existing marigolds to produce lutein ointment. The present invention is mainly in the extraction mode, after the extraction is completed, the hydraulic pressure difference control to the evaporation tank or the temporary storage tank, the storage function of the temporary storage tank used in the original production process is changed to the impurity settling function, and the time and temperature of evaporation in the evaporation tank The matching technology and the control technology of the filter inlet and outlet valves constitute the production process technology; in addition, the selection and matching of the filter me...
