Sugar mainly consists of white sugar, brown sugar, and rock sugar. The main component of these three sugars is sucrose (the main component of beet sugar is also sucrose). Sugar is one of the main sources of human nutrition. The consumption of the human body should be maintained through the thermal energy generated after sugar oxidation. About 70% of the energy required for human activities is provided by sugar.

The production of sugar is mainly divided into two categories: traditional sugar cooking techniques and modern industrial production. The traditional sugar boiling process can only be produced using sugarcane as the raw material. Modern technology involves extracting juice from sugarcane or beets, filtering out impurities, and then adding other substances for precipitation and re filtration.

China is one of the major sugar producing and consuming countries in the world. At present, modern industrial production still uses bicarbonate method and sulfite/phosphoric acid method for sugar production, while special separation equipment for sugar production uses membrane technology. Due to its energy-saving, efficient, simple process, and convenient operation, it will gradually replace traditional separation processes.

Special separation equipment（ http://www.nongsuofenli.com ）It has been widely used for the concentration, separation, and decolorization of sugars. For the concentration of sugars, if traditional thermal concentration processes are used, there are drawbacks such as high investment and high energy consumption. However, membrane technology is used for the concentration and separation of sugars, and its stable molecular retention rate can ensure a high retention rate of sugars under low pressure, achieving concentration effects. The special nanofiltration membrane separation equipment can concentrate sugar from 12b to 30b, and allow inorganic compound substances to permeate through the sugar solution. When the sugar content is 30b, the dedicated nanofiltration membrane special separation equipment can achieve a water removal rate of up to 60%. Ultrafiltration membrane special separation equipment can be used for purifying sugar solution, removing sugar solution, and replacing traditional activated carbon adsorption process. In the above applications, all special separation equipment adopts special membrane channels to reduce the pre filtration requirements for sugar solutions.
