In this traditional glucose production process, it is necessary toSaccharification solution drum or plate frame filtrationWhen adding filter aids, activated carbon must be used as an adsorbent for decolorization. In the fixed bed process, the consumption of regenerant is high, the consumption of raw materials is large, the production cost is high, and it is easy to cause environmental pollution.
In response to the shortcomings of traditional saccharification liquid treatment processes, the company adopts ceramic membranes/The combination of roll membrane filtration and continuous ion exchange desalination technology is used to reform the production process of glucose.
Chengdu Zhongzhi Filtration Technology Co., Ltd. has conducted extensive experimental research on membrane technology and has achieved industrialization. Provide comprehensive process engineering solutions related to separation, purification, and clean production for customers in different industries.
Compared with traditional processes, this process not only reduces production costs, but also enables continuous automated production, making it a new energy-saving, consumption reducing and clean production technology. The specific advantages of the process are as follows:
1. The ceramic membrane/roll membrane separation technology is used to remove impurities such as fat, macromolecular proteins, fibers, pigments, etc. from the saccharification solution. The sugar solution filtered by the membrane is clear and transparent, and the filtrate has a light transmittance of over 97%, which can eliminate the traditional process of activated carbon decolorization and greatly reduce the amount of front-end filter aid used, saving production costs;
2. Replacing traditional fixed bed processes with continuous ion exchange technology can save over 70% of resin, over 40% of regenerant usage, and over 60% of washing water usage, greatly reducing production costs and environmental pressure on wastewater;
3. Using nanofiltration separation technology instead of traditional crystallization centrifugation process to prepare pharmaceutical grade glucose, the product purity is as high as 99.5%, and the product quality is stable.
Application fields:
1. Fiber fuel ethanol is separated and concentrated using cellulase, and glucose is concentrated;
2. Glycosylation solution decolorization and protein removal, desalination purification;
3. Separation of disaccharides from high-purity glucose and fructose to improve purity;
4. Separation and purification of mannitol and sorbitol for disaccharide alcohol;
5. Separation of dilute sugar solution and chromatographic separation of dilute solution for energy saving;
6. Continuous enzymatic hydrolysis of oligosaccharides and separation and concentration of enzymes to improve enzyme utilization and reduce energy consumption and emissions;
7. Xylose and oligosaccharides are used for colloid removal, protein decolorization, continuous deacidification and desalination, and energy-saving concentration;
8. Separation and purification of small molecule sugars from glucose, oligosaccharides, and polysaccharides, and energy-saving of polysaccharide concentration;
9. Purification and recovery of crystallization mother liquor such as xylose, xylitol, sorbitol, erythritol, fructose, glucose, etc
