Description

technical field [0001] The invention relates to a device for extracting eucommia gum, in particular to a vacuum pulse type eucommia gum extracting device. Background technique [0002] Eucommia gum exists in Eucommia leaves, bark and fruit. Eucommia gum and natural rubber have the same chemical composition, but different molecular structures. Eucommia gum is trans-polyisoprene, while natural rubber is cis-polyisoprene. Due to the different vulcanization methods of the same Eucommia gum molecule, it can be in rubber state or different plastic state. Therefore, Eucommia gum has very important application value and is an emerging functional material with multiple uses. [0003] Eucommia gum is easily soluble in non-polar solvents such as petroleum ether, and generally can only be extracted with non-polar solvents such as petroleum ether, but the penetration of non-polar solvents to hydrophilic substances such as cellulose, pectin and lignin Poor, Eucommia gum is wrapped by pl...

AI Technical Summary

Problems solved by technology

[0003] Eucommia gum is easily soluble in non-polar solvents such as petroleum ether, and generally can only be extracted with non-polar solvents such as petroleum ether, but the penetration of non-polar solvents to hydrophilic substances such as cellulose, pectin and lignin Poor, Eucommia gum is wrapped by plant cell tissue with cellulose, pectin and lignin as the main components, so there is a large mass transfer resistance in the extraction process with non-polar solvents such as petroleum ether, and the solvent is difficult Through the plant cell tissue to dissolve Eucommia gum, the solution dissolved in Eucommia gum is also difficult to release, the extraction time is long and the efficiency is low

[0004] Existing common extraction equipment is used for the extraction of eucommia gum, all of which have the problems of large mass transfer resistance, long extraction time and low efficiency, and the rubber content of the material after extraction of eucommia gum is also high, resulting in a lot of waste of eucommia gum resources and loss, thus, the existing technology can not meet the requirements of Eucommia gum extraction
