Embodiment 1

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] A method for extracting Eucommia gum from Eucommia bark using an enzymolyzer, comprising the steps:

[0034] 1), first use a hay cutter to cut the bark of Eucommia bark as a raw material into an area no larger than 25cm 2 Then put it into clear water at room temperature and soak it for 12 hours, then take it out, put it into the blasting machine and blast it to get Eucommia bark intermediate I for later use;

[0035] In this step, the blasting temperature is controlled below 50°, the blasting pressure is controlled between 1.4MPa, and the blasting time is controlled at 0.3S;

[0036] 2), the Eucommia bark intermediate I obtained in step 1) was put into the aqueous solution of protease and stirred and washed repeatedly for 5 hours, and then stirred and washed repeatedly with clean water for 1.5 hours to obtain the Eucommia bark...

Embodiment 2

[0044] A method for extracting Eucommia gum from Eucommia bark using an enzymolyzer, comprising the steps:

[0045] 1), first use the hay cutter to cut the eucommia bark as raw material into an area no larger than 25cm 2 Then put it into clear water at room temperature and soak it for 12.5 hours, then remove it, put it into a blasting machine, and blast it to obtain Eucommia bark intermediate I for later use;

[0046] In this step, the blasting temperature is controlled below 50°, the blasting pressure is controlled between 1.6MPa, and the blasting time is controlled at 0.4S;

[0047] 2) Put the eucommia bark intermediate I obtained in step 1) into the aqueous solution of protease and repeatedly stir and wash for 5.5 hours, then repeatedly stir and wash with water for 2 hours to obtain the eucommia bark intermediate II:

[0048] When washing in this step, the various components are configured according to the following parts by weight: 100 parts of Eucommia bark intermediate ...

Embodiment 3

[0055] A method for extracting Eucommia gum from Eucommia bark using an enzymolyzer, comprising the steps:

[0056] 1), first use the hay cutter to cut the eucommia bark as raw material into an area no larger than 25cm 2 Then put it into clear water at room temperature and soak for 13 hours, then remove it, put it into a blasting machine, and blast it to obtain Eucommia bark intermediate I for later use;

[0057] In this step, the blasting temperature is controlled below 50°, the blasting pressure is controlled between 1.8MPa, and the blasting time is controlled at 0.5S;

[0058] 2), the Eucommia bark intermediate I obtained in step 1) was put into the aqueous solution of protease, stirred and washed repeatedly for 6 hours, and then stirred and washed repeatedly with clean water for 2.5 hours to obtain the Eucommia bark intermediate II:

[0059] When washing in this step, the various components are configured according to the following parts by weight: 110 parts of Eucommia b...

Abstract

A method for using an enzymatic hydrolysis device to extract eucommea rubber from eucommia bark is as follows: eucommia bark is detonated and crushed, proteins, cell dividing walls and intercellular layers, cellulose and hemicelluloses are respectively decomposed from the eucommia bark successively by protease, pectinase and cellulose, so that non rubber substances in the eucommia bark can be completely separated from the eucommea rubber, a target substance and waste components are separated by the method of rotation of a separating cylinder of the enzymatic hydrolysis device in a water tank, the inner wall of the separating cylinder is provided with a plurality of rows of bending plate mixing blades with the cross section in the shape of an angle, a plurality of mixing blades in each row are in ladder like distribution along the axial direction of a supporting shaft, the included angle of the bending plate is not less than 120 degrees, an inclination angle between the mixing blades and the supporting shaft is 10 to 15 degrees, the bending plate is provided with long holes in stagger manner, complete separation of the target substance and the waste components can be ensured, and the method has the advantages of cleaning, safety, environmental protection, low cost, high efficiency, high eucommea rubber extraction purity reaching more than 92%, and suitability for production in industry.

Description

technical field [0001] The invention relates to a method for extracting natural gum, in particular to a method for extracting eucommia gum from eucommia bark by using an enzymolyzer. Background technique [0002] Eucommia ulmoides is a precious tree species unique to my country. Eucommia ulmoides gum contained in eucommia ulmoides, as a natural rubber, has the advantages of high insulation and corrosion resistance. It is a high-quality material for manufacturing submarine cables. Medicine container and excellent raw material for dental fillings. Eucommia gum can also be used to make medical splints, automobile tires, shape memory materials, temperature detection materials, modified plastics and other rubber products, so it has broad application prospects. [0003] There are two types of existing methods for extracting Eucommia gum from Eucommia ulmoides, one of which is: the raw material bark of Eucommia ulmoides is fully fermented and then boiled with a strong alkali aqueou...
