Glucose is one of the most widely distributed and important monosaccharides in nature, and is a polyhydroxy aldehyde. Pure glucose is colorless crystals, has sweet taste but less sweet than sucrose, is easily dissolved in water, is slightly dissolved in ethanol, and is insoluble in diethyl ether. The aqueous solution of natural glucose is optically active to the right, so it is "dextrose". Glucose requires a decolorization treatment during the production process.
The existing decoloring equipment for glucose production cannot be used for accelerating mixing of active carbon in materials in the using process, and a plate-and-frame filter is generally used for filtering decolored materials, so that the filtering speed is low, and the production efficiency of glucose is reduced.

However, the decoloring device for glucose production lacks a impurity removing mechanism before decoloring glucose, and the original glucose solution generally contains a lot of impurities, so that if the decoloring device is directly subjected to the decoloring treatment, impurities in the solution can block meshes on a filter screen to influence the filtering speed of the glucose solution, and the working efficiency is reduced.
