[0005] 2. [Title] The influence of canceling the secondary sulfur fumigation of syrup in Yafa Sugar Factory on the recovery and quality [Author] Yang Fuzhong, Yang Xinde, etc. [Institution] Yunnan Yongde Sugar Group Co., Ltd., [Title] Guangxi Light Industry. 2002 (5) .-12-14【Keywords】Sulfurous sulfite sugar refining process improvement scouring recovery rate syrup secondary sulfur fumigation quality 【Abstract】In sugar production, the secondary sulfur fumigation of syrup in sulfite sugar factory is a necessary process control method, but the secondary sulfur fumigation of syrup has also brought some well-known adverse effects on the sugar production process, such as the conversion loss of sugar under acidic conditions, the product SO 2 high content
[0009] Although the above documents introduce that the color value of sugar juice can be reduced by changing the process or adding additives, and the secondary sulfur fumigation of syrup can be canceled under certain conditions, but none of them can replace the decolorization effect achieved by sulfur fumigation, and can only be used in the sugar production process. play an auxiliary role
In addition, the research institutes of sugarcane sugar production bases in my country, Guangzhou Sugarcane Chemical Industry Research Institute, Guangxi University, Guangxi Light Industry Research Institute and other units have also been working on the research of new technology of sugar cane sugar production instead of sulfur fumigation in recent years, but many of them are still in the research stage , it is difficult to implement in actual production

Embodiment 1

[0046] Take 500ml of virgin juice from a sugar factory, add 350PPM / L phosphoric acid, add lime milk, add 10mg of chitosan with a molecular weight of 10,000 to 1 million as a sucrose compound additive, and control the pH value between 6.8 and 7.2 , shake and stir, then heat to 35°C, add the bubble solution of the simple bubble-making mechanism, add 1-5PPM polyacrylamide, and observe that the flocs float up quickly. To meet the clear juice requirements of the color value required for sugar production.

Embodiment 2

[0048] In a sugar factory, a φ3000 floater is used. According to the production process, a φ3000 floater system is installed in the press room, adding 300-350PPM phosphoric acid, lime milk, and sucrose compound additives (molecular weight between 50,000 and 3 million. Chitosan, 0.5g per cubic meter of syrup), foamed with a pressure-melting foaming system, after adding 15PPM polyacrylamide, the scum began to float, the concentration of the scum was high, and the amount was small, accounting for about 5% of sugarcane juice quantity. Compared with cane juice, the purity of floating clear juice is 1.73AP higher, and the color value is 233IU lower than that of the original clear juice. When entering the next process, it can produce first-grade white sugar.

Embodiment 3

[0050] After the sugarcane raw material enters the factory, it is torn apart and squeezed multiple times, and the obtained cane juice is directly added with lime, and the amount of phosphoric acid added is 350PPM, and the pH value is adjusted to neutral, and then heated to about 34-37°C, adding sucrose compound additives - Chitosan with a molecular weight of 10,000 to 1 million is added in an amount of 1 to 100 mg / kg sugarcane juice, and enters the low-temperature floater, and the scum returns to the middle conveyor belt of the press, and enters the press process. The floating clear juice is pumped for secondary heating, heated to about 90-95°C, and enters the fast settler, and the sediment is discharged to the mixing reaction tank, and after being mixed with the raw cane juice, it also enters the floater for retreatment, and the settled juice is heated to 102°C After ~105°C, enter the evaporating tank for concentration, and after concentration to 55~60°BX, add phosphoric acid ...

Abstract

The invention relates to a production method of high-quality sugar, specifically to an improvement of a technology of sugar refinement and purification. High-quality white granulated sugar products are obtained after sugar canes are torn, pressed, cane juice is defecated, mixed juice is heated, a cane sugar complex auxiliary agent is added, the mixed juice is stirred up, floating juice is heated, sedimentated and vaporized, phosphoric acid and the cane sugar complex auxiliary agent are added, syrup is stirred up, the process of honey separation is carried out, the mixture is boiled, refined, crystallized, dried and packed. As the method of the invention adopts a low-temperature technology and a floating treatment method of adding the phosphoric acid, lime and the cane sugar auxiliary agent to lead the floating juice to reach or exceed the effect of the floating juice by original traditional technology, and utilizes a syrup floating principle and a scruff repressing method to substitute the sediment, filtration and stoving technology in the prior art, and cancels such technologies and equipment thereof as filtration, neutralization and sulfur dioxide gas system, retention time in cane juice production process is shortened, sulfur is used as a clarifier during the whole technical process, and sugar without sulfur is produced, thus improving product quality as well as reducing cost.

Description

technical field [0001] The invention relates to a production method of sucrose, in particular to an improvement of a clean sugar production process. Background technique [0002] In the cleaning process part of sugar technology, there are many cleaning methods. At present, in China, the carbonic acid method and the sulfurous acid method are mainly used. The carbonation method is a cleaning method that adds a large amount of lime and carbon dioxide to the sugar juice to generate a large amount of calcium carbonate. The sulfite method is a cleaning method that generates a large amount of sulfite as a detergent by adding phosphoric acid, lime and carbon dioxide. Both methods require the use of more special equipment, both of which have complex processes and high investment in equipment. Among them, the carbonic acid method has large investment, complex process, high production cost, and the filter mud cannot be reused, causing environmental pollution and other problems. The...
