New additive for producing sugar from sugarcane, preparation method thereof and application method thereof in sugar production

Abstract

The invention discloses a new additive for producing sugar from sugarcane, a preparation method thereof and an application method thereof in a sugar production. The new additive comprises the following raw materials by weight parts: 100 parts of concentrated phosphoric acid, 0.5 to 50 parts of chitosan and 15 to 90 parts of diatomite used as a carrier raw material. The preparation method comprises adding 0.5 to 50 parts of the chitosan into 100 parts of the concentrated phosphoric acid, reacting for 30 to 120 minutes under a temperature of 8 to 300 DEG C, generating a new sugar-production additive of polyphosphate polymer compound with a strong positive charge and a high fiber after complete reaction, and absorbing the above reaction product with 15 to 90 parts of the diatomite to prepare the new additive with relatively high performance. The new additive, completely instead of sulfur dioxide, is used in cane sugar manufacture industries to decolorize and clarify sugarcane juice, mixed juices thereof and pre-heated and pre-limed juice, and as well can be used to re-treat clear juice or syrup. According to the invention, safe, green, environmental-protection and high-quality sugar products is ensured to produce.

Description

technical field [0001] The invention relates to an auxiliary agent, in particular to a new auxiliary agent for sugar cane sugar production, a preparation method and an application method in sugar production. Background technique [0002] In the existing sugar cane sugar production process, the cleaning process is the focus of the sugar production process. Since the sugar factory needs to process a large amount of sugar cane juice every day, ranging from several thousand tons to tens of thousands of tons, and sugar cane juice is a A multi-component solution, itself is a colloid, and due to the influence of various conditions, the components contained are variable and unstable, and complex physical and chemical changes often occur, which brings many unexpected to the cleaning process. Difficulties. [0003] At present, the world's sugar industry generally uses a large amount of sulfur dioxide produced by burning sulfur as the main refining aid to carry out sulfur fumigation f...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a new type of sugarcane juice that can effectively treat sugarcane juice without using sulfur dioxide, aiming at the defect that sulfur dioxide and its derivatives remain in white sugar caused by the decolorization and clarification treatment of sugarcane juice by sulfur dioxide in the prior art. A new additive for sugar cane sugar production with decolorization and clarification, safe and no harmful residues
