Embodiment 1

[0028] A method for extracting antioxidants from refined sugar separation waste liquid, it comprises the following steps:

[0029] Step (1) Ion exchange treatment: Use ion exchange resin to desalt and decolorize the collected sugarcane clarified juice. After the adsorption capacity of the ion exchange resin is saturated, use NaOH solution with a mass concentration of 0.5-2.5% and NaOH solution with a mass concentration of 1-10%. The mixed solution of NaCl solution is used to elute and regenerate the ion exchange resin to obtain a dark brown opaque regenerated waste liquid containing insoluble solids, acid radical ions, alkali and salt;

[0030] Step (2) Filtration of impurities in the regeneration waste liquid: take 50L of the regeneration waste liquid, and filter out the insoluble impurities in the regeneration waste liquid;

[0031] Step (3) Nanofiltration membrane filtration of regenerated waste liquid: use nanofiltration membrane to filter the regenerated waste liquid to r...

Abstract

The invention discloses a method and device for extracting an antioxidant from ion exchange waste liquid of refined sugar. The method comprises the following steps of step (1) performing ion exchange treatment; step (2), performing impurity filtration on regenerated waste liquid; step (3) performing nanofiltration membrane filtration on the regenerated waste liquid; and step (4) drying concentrated liquid. According to the method and device for extracting the antioxidant from the ion exchange waste liquid of the refined sugar disclosed by the invention, the sewage treatment quantity and the treatment cost of sugar making enterprises can be effectively reduced, and the economic benefits of the sugar making enterprises can be significantly increased.

Description

technical field [0001] The invention relates to the technical field of recovery and utilization of sugar refining waste liquid, in particular to a method and device for extracting antioxidants from refined sugar separation waste liquid. Background technique [0002] Antioxidants refer to substances that can retard or even eliminate certain oxidation effects. A large number of medical studies in recent years have proved that various diseases and premature aging of the human body are caused by excessive oxygen free radicals (free radicals) in the body that oxidize and destroy normal cells. Antioxidants can eliminate these oxygen free radicals and slow down the oxidation reaction, so they have good health care, anti-aging and disease reduction effects. Pigment polyphenols contained in sugarcane have high antioxidant activity. Extracting high value-added antioxidant active substances from ion exchange resin regenerated decolorization solution, and recycling the regenerant at th...
