Abstract

The invention provides a method for producing eucommia ulmoides gum. The method comprises cleaning, fermentation, washing, stewing, smashing, sieving, rinsing and briquetting. The method comprises the following steps of 1, putting leaves of eucommia ulmoides into a tank and carrying out cleaning, 2, feeding the cleaned leaves of eucommia ulmoides into a fermentation tank, carrying out fermentation, feeding the fermentation products into a water extractor and carrying out washing and drying, 3, putting the dried fermentation products into a stewing device and carrying out stewing, 4, feeding the stewing products into a waterpower smasher and carrying out smashing under the conditions of a waterpower smashing concentration of 2-20%, humidity less than 50%, a waterpower smashing rate of 20-80m / s and the optimal waterpower smashing rate of 30-50m / s, 5, sieving the smashed gum by a sieving device, 6, rinsing the gum silk obtained by the sieve analysis device in a rinsing device, and 7, feeding the eucommia ulmoides gum into a briquetting device and carrying out briquetting molding. The method reduces a material consumption amount, reduces pollution, improves a yield, reduces a production cost, and improves elasticity, toughness and tensile strength of the eucommia ulmoides gum.

Description

technical field [0001] The invention relates to a method for extracting natural substances, more specifically, the invention relates to a process for extracting Eucommia gum. Background technique [0002] Eucommia gum is a white filament that exists in the glue-containing cells of each organ of Eucommia, and it is a special natural polymer material (trans-polyisoprene). With the success of converting natural eucommia gum into trans-polyisoprene vulcanized rubber, it has the characteristics of thermoplasticity, insulation, water resistance, acid and alkali resistance, and will have extensive value in many fields. However, the low yield rate of eucommia gum, the complexity of the extraction process, high production costs and serious environmental pollution severely limit its industrial production. Previously, the extraction methods of eucommia gum were divided into two types: broken cell wall method and solvent extraction method: such as high-speed water conservancy stirring ...
