Embodiment 1

[0024] (1) Impurity removal and crushing

[0025] Remove impurities such as sediment and bark, and then use a pulverizer to pulverize the gum arabic;

[0026] (2) Hydrolysis

[0027] Put the crushed gum arabic and water into the reaction kettle at a ratio of 1:8, stir evenly, add a protective agent at 50°C, and continue to heat up to 75°C at a constant temperature for 8 hours to obtain a concentration of 10% and a viscosity of 10-50Mpa. s Arabic collagen solution.

[0028] (3) clarification and decolorization

[0029] The Arabic collagen solution is directly pumped from the reaction kettle to the clarification tank for clarification. Because colored substances are easily produced during hydrolysis, a decolorizing agent is added for decolorization treatment. After 30 hours of precipitation and decolorization, the decolorized glue is obtained.

[0030] (4) centrifugal impurity removal

[0031] The clarified glue enters the high-speed tubular separator, and the strong centrif...

Embodiment 2

[0041] (1) Impurity removal and crushing

[0042] Remove impurities such as sediment and bark, and then use a pulverizer to pulverize the gum arabic;

[0043] (2) Hydrolysis

[0044] Put the crushed gum arabic and water into the reaction kettle at a ratio of 1:9, stir evenly, add a protective agent at 55°C, and continue to heat up to 80°C at a constant temperature for 10 hours to obtain a concentration of 10% and a viscosity of 10-50Mpa. s Arabic collagen solution.

[0045] (3) clarification and decolorization

[0046] The Arabic collagen solution is directly pumped from the reaction kettle to the clarification tank for clarification. Because it is easy to produce colored substances during hydrolysis, a decolorizing agent is added for decolorization treatment. After 36 hours of precipitation and decolorization, the decolorized glue is obtained.

[0048] The clarified glue enters the high-speed tubular separator, and the strong cent...

Embodiment 3

[0058] (1) Impurity removal and crushing

[0059] Remove impurities such as sediment and bark, and then use a pulverizer to pulverize the gum arabic;

[0060] (2) Hydrolysis

[0061] Put the pulverized gum arabic and water into the reaction kettle at a ratio of 1:7, stir evenly, add a protective agent at 45°C, and continue to heat up to 70°C at a constant temperature for 6 hours to obtain a concentration of 10% and a viscosity of 10-50Mpa. s Arabic collagen solution.

[0062] (3) clarification and decolorization

[0063] The Arabic collagen solution is directly pumped from the reaction kettle to the clarification tank for clarification. Because colored substances are easily produced during hydrolysis, a decolorizing agent is added for decolorization treatment. After 24 hours of precipitation and decolorization, the decolorized glue is obtained.

[0064] (4) centrifugal impurity removal

[0065] The clarified glue enters the high-speed tubular separator, and the strong cent...

Description

technical field [0001] The invention relates to a production and processing technology of gum, in particular to a production and processing technology of gum arabic powder. Background technique [0002] Gum Arabic is derived from the dry and solid jelly exuded from the trunk of the leguminous acacia tree or its close species. Gum Arabic can be used in the pharmaceutical and food industries as Gum Arabic powder after being dissolved and removed. It can be widely used in medicine, Adhesives used in food, cosmetics, chemical building materials, electronics, printing and other industries are natural emulsifiers, thickeners, suspending agents, film-forming agents, glazing agents, and stabilizers. Traditional gum arabic powder refers to the current domestic process of crushing and grinding after manual selection. The process is too simple, and the produced products have the disadvantages of low quality, unstable performance, and low extraction purity. Contents of the invention ...
