Abstract

The invention belongs to the technical field of extracting of glue solution of cortex eucommiae, and particularly relates to a refining technology of a crude glue solution of cortex eucommiae. The refining technology is characterized in that a flotation agent contains an acroleic acid and acrylamide copolymer, and specifically comprises the following steps of (1) adding the floatation agent into the dissolved liquid of the crude glue of the cortex eucommiae; (2) heating, and stirring; (3) settling. The refining technology has the beneficial effect that the crude glue solution of the cortex eucommiae is refined, especially the special flotation agent is adopted, the impurities in the crude glue solution of the cortex eucommiae are thoroughly flocculated and precipitated as much as possible,and a good foundation condition is provided for improving the purity of the glue of the cortex eucommiae.

Description

technical field [0001] The invention belongs to the technical field of eucommia gum extraction, and in particular relates to a refining process of eucommia crude gum. Background technique [0002] Regarding the refining process of eucommia ulmoides gum, there are few patent literature disclosures. The applicant has done a series of research on the refining system. For example, the applicant disclosed a eucommia gum refining system in CN103102494A; A continuous dissolving device for refining Eucommia gum; CN203112734U also discloses a system for refining Eucommia gum. [0003] In the article "Research on the Extraction Method of Eucommia Gum" in the journal "Journal of Fujian Forestry University", Lu Zhike and others comprehensively tested and studied the extraction method of Eucommia ulmoides gum in Eucommia fruit material. , and then freeze, change the solvent solubility parameters, use the temperature difference to cause phase separation and rapid precipitation, and obtai...
