Problems solved by technology

[0006] The current ion exchange method including the use of ion exchange resins and ion exchange fibers can achieve less sulfur and less phosphorus, but in fact, the sulfur and phosphorus components in traditional clarifiers, flocculants and other detergents will promote The pigment is oxidized to make the color darker, and acid radical ions and metal ions will also be exchanged by ion exchange fibers, which will increase the exchange burden

Embodiment Construction

[0052] according to figure 1 process is carried out.

[0053] 1. Crushing: The index control of sugarcane crushing is the same as the traditional process.

[0054] 2. Clarification:

[0055] 1. Screening: the sieve hole is 100 mesh;

[0056] 2. Pre-ash to adjust the pH range of sugarcane juice to 6.4-7.2;

[0057] 3. The primary heating temperature is 60-70°C;

[0058] 4. Add lime milk to adjust the pH range of the sugar juice to 7.0-8.0;

[0059] 5. The second heating temperature is 100-103°C;

[0060] 6. Settling: the clarified juice is transferred to the next process; the mud juice is processed by vacuum suction filtration, and the filtered clarified juice is transferred to the next process, and the filtered mud is treated as waste;

[0061] 7. Three-stage filtration: Filtration is divided into three steps of 80 mesh, 200 mesh and 300 mesh.

[0062] Three, decolorization:

[0063] 1. Pretreatment, including: first filter through a filter with a pore size of 10 μm, a...

Abstract

A new highly efficient ion-exchange fiber decoloring sulfur-free phosphorus-free sugar-making technology comprises the following steps: 1) squeezing, screening, pre-liming, first heating, addition of lime milk and second heating; 2) settlement and tertiary screening; 3) anion-exchange fiber decoloring, cation exchange fiber desalination and anion-exchange fiber decoloring; and 4) third heating, evaporation, sugar boiling, sugar separating and drying. Finally, a finished production is obtained. According to the new technology, sulfur-free and phosphorus-free purposes are realized by advantages of ion-exchange fiber. The technology is simple and is adopted to raise quality index of sugar juice. Quality of the product is good. In addition, energy is saved and environmental pollution is minimized.

Description

technical field [0001] The invention relates to a sugar-making process, in particular to a new technology for high-efficiency decolorization of ion-exchange fiber, phosphorus-free and sulfur-free sugar-making. Background technique [0002] The sugar cane sugar production process mainly includes the sulfurous acid method and the carbonic acid method, and more than 90% of the sugar factories use the sulfurous acid method to produce first-grade white granulated sugar and high-grade white granulated sugar. No matter which method is used, clarifiers and other ingredients need to be added to remove a large amount of impurities such as pigments, colloids, and non-sugar. The clarifiers, flocculants and other detergents commonly used today are lime, calcium sulfite, calcium phosphate, superphosphate, phosphoric acid, sulfur dioxide, carbon dioxide, etc., through the precipitation, flocculation, complexation and other functions of these components. , colloid, non-sugar and other impu...
