preparation example Construction

[0034] The production system adopted in the preparation process of the present invention includes a mixed juice tank 1, a static mixer I7, a static mixer II8 and a sulfur fumigation device 10 connected in sequence. Mixed juice tank 1 is connected with static mixer I7 through pipelines, and is connected with enzyme tank I3, enzyme tank II4, -enzyme tank III5 and enzyme tank IV6.

[0035] The milk of lime tank 2 is respectively connected with the pipeline at the inlet of the static mixer I7 and the inlet of the static mixer II8. At the inlet of the static mixer I7, a metering pump is used to quantitatively add the milk of lime and transport it to the static mixer I7 for mixing. , adjust the pH to 6.0. Phosphoric acid tank I901 and phosphoric acid tank II902 are connected with the outlet of static mixer I7, and phosphoric acid is added quantitatively at the outlet of static mixer I with a metering pump, and lime is quantitatively added at the inlet of static mixer II with a meter...

Embodiment 1

[0038] A sugar clarification process, comprising the following steps:

[0039] S1. Decolorization treatment:

[0040] The sugarcane is squeezed and extracted to obtain mixed juice, and polyphenol oxidase and anthocyanidase are added to the mixed juice for decolorization treatment to obtain the enzyme-added mixed juice.

[0041] The usage amount of the polyphenol oxidase is 0.5U / mL mixed juice; the usage amount of the anthocyanidase is 0.2U / mL mixed juice.

[0042] S2. Pre-ash:

[0043] adding milk of lime and phosphoric acid to the enzyme-added mixed juice for prelime treatment to obtain prelime juice;

[0044] The prelime treatment is to firstly add lime milk to adjust the pH of the enzyme-added mixed juice to 6.0; then add phosphoric acid, and then add lime milk to adjust the pH to 7.0.

[0045] The amount of phosphoric acid added is 250ppm of the weight of the enzyme mixed juice.

[0046] S3. Neutralization by sulfur fumigation:

[0047] The prelime juice is neutralize...

Abstract

The invention provides a sugar-making clarification process, which comprises the following steps: S1, decolorization treatment: enabling sugarcane to be squeezed to extract juice to obtain mixed juice, and adding polyphenol oxidase and anthocyanin enzyme into the mixed juice to conduct the decolorization treatment to obtain enzyme-containing mixed juice; S2, preliming: adding lime milk and phosphoric acid into the enzyme-containing mixed juice to conduct preliming treatment to obtain preliming juice; the preliming treatment relates to adding the lime milk firstly to adjust the pH value of theenzyme-containing mixed juice to be 6.0; afterwards, adding the phosphoric acid, and then adding the lime milk to adjust the pH value to be 6.8-7.2; and S3, sulphitation and neutralization. Enzyme-assisted decolorization, preliming, and sulphitation and neutralization treatment are adopted to clarify, the color value can be effectively reduced, and the clarity can be effectively improved, so thatthe quality of white granulated sugar is improved.

Description

technical field [0001] The invention relates to the technical field of sugar production, in particular to a sugar clarification process. Background technique [0002] my country is one of the earliest countries in the world to use sugar cane to make sugar. According to different sugar cane sugar making processes, there are mainly three methods: lime method, sulfurous acid method, and carbonic acid method. After years of construction and development, my country's sucrose industry has achieved remarkable achievements. Especially in recent years, with the expansion of sugar production scale year by year, the progress of production technology and the continuous improvement of management, sugar enterprises have achieved good social and economic benefits. At present, the production process adopted by most domestic sugar factories is the traditional sulfite clarification process. This production method has the characteristics of simple process, low investment and high yield. [0...
