Problems solved by technology

For example, the combination of sulfurous method and phosphorus floatation method can effectively reduce the sulfur content in sugar products, but due to the lengthening of the process flow, it will cause additional loss of sucrose and increase in color value; and the development of efficient decolorizers is very important for the sulfurous method. Effective supplementation or improvement of the clarification process is also one of the reform directions of the sugar clarification process

Embodiment 1

[0024] Embodiment 1: a kind of sugar juice compound decolorizing agent, this sugar juice compound decolorizing agent is made of H 2 o 2 H with vitamin C 2 o 2 -Vc complex reagent, H 2 o 2 The mass ratio to vitamin C is 0.01-10, preferably 0.3-1.0, more preferably 0.6.

Embodiment 2

[0025] Embodiment 2: a kind of method for sugar juice decolorization, adopt the H described in embodiment 1 2 o 2 -Vc compound reagent carries out decolorization treatment to sugar juice, and described sugar juice is mixed juice, adopts H 2 o 2 -Vc composite reagent decolorizes the mixed juice, during the decolorization process, H 2 o 2 -The mass ratio of the addition amount of Vc composite reagent to the mixed juice is 10×10 -6 ~2×10 -3 , about to H 2 o 2 -Vc compound reagent is added to the mixed juice from the press, before sulfur fumigation and neutralization, the mixed juice is mixed with H during the flow and pumping process, or in the buffer storage tank 2 o 2 The -Vc complex reagent is fully mixed and reacted to achieve the purpose of decolorization.

Embodiment 3

[0026] Embodiment 3: a kind of method for juice decolorization, adopt the H described in embodiment 1 2 o 2 -Vc compound reagent carries out decolorization treatment to sugar juice, and described sugar juice is clear juice, adopts H 2 o 2 -Vc compound reagent decolorizes the clear juice, during the decolorization process, H 2 o 2 -The mass ratio of the addition amount of Vc composite reagent to the clear juice is 10×10 -6 ~2×10 -3 , about to H 2 o 2 -Vc compound reagent is added to the clear juice, and the clear juice will be mixed with H in the process of flowing and pumping, or in the buffer storage tank 2 o 2 The -Vc complex reagent is fully mixed and reacted to achieve the purpose of decolorization.

Abstract

The present invention relates to a kind of sugar juice compound decolorizing agent and the method for sugar juice decolorizing, and this sugar juice compound decolorizing agent is made of H 2 o 2 H with vitamin C 2 o 2 ‑Vc Complex Reagent, H 2 o 2 The mass ratio of vitamin C to vitamin C is 0.01 to 10; the method for decolorizing the sugar juice is: using H 2 o 2 ‑Vc composite reagent decolorizes the sugar juice, which is mixed juice, clear juice, syrup or / and massecuite. During the decolorization process, H 2 o 2 ‑The mass ratio of the amount of Vc composite reagent added to the corresponding sugar juice is 10×10 ‑6 ~2×10 ‑3 . The invention can greatly reduce the color value of the sugar juice and the residual amount of sulfur dioxide, effectively reduce the content of colored substances and the residual amount of sulfur in the final white granulated sugar, and at the same time improve the purity of the white granulated sugar, thereby improving the whiteness of the finished product. The quality of granulated sugar; on the other hand, the process is simple, there is no need to change the original process flow, and the investment and operation costs are low, which significantly improves the economic benefits of the sugar factory.

Description

technical field [0001] The invention relates to a compound decolorizing agent for sugar juice and a method for decolorizing sugar juice. Background technique [0002] The color value of white granulated sugar is the most important and most technically difficult quality index of white granulated sugar. There are many and complex types of colored substances in sugar products, including two types of colored substances originally contained in sugarcane and those produced during the production process. The original pigments contained in sugarcane are mainly fat-soluble and water-soluble. The former coexists with lipids in sugarcane juice and is basically insoluble in water. Most of them can be removed when heated. Water-soluble pigments are mainly various polyphenols, which are the main reason for coloring white granulated sugar and various sugar products. On the other hand, in the sugar production process, in addition to clarification treatment to remove some colored substance...
