This application discloses a single-column simulated moving bed chromatography system for separating fructose syrup, comprising a single long chromatographic column and a precision fluid delivery and control system. The single long chromatographic column has a height-to-diameter ratio of 12:1 to 20:1, and 6-10 multi-functional interfaces are uniformly arranged along the axial direction, with high-precision multi-channel rotary distribution valves connected to the interfaces. The precision fluid delivery and control system includes a central controller, an execution layer, a detection layer, and a human-machine interface layer. The central controller is connected to the execution layer, the detection layer, and the human-machine interface layer via an industrial bus, forming a fully closed-loop automatic control architecture. This system solves the technical defects of traditional multi-column simulated moving bed fructose syrup separation equipment, such as complexity, high investment, and low separation efficiency, as well as the difficulty in achieving both purity and yield in existing single-column chromatography, and the inability to stably produce pharmaceutical-grade high-purity fructose.

The application discloses a kind of selective adsorption material and its preparation method and application.The preparation method of selective adsorption material of the application includes the following steps: 2,5-thiophene dicarboxylic acid sodium, aluminium chloride and sodium metaaluminate are dissolved in water to carry out reflux reaction, then product separation, purification and drying are carried out, to obtain selective adsorption material.The selective adsorption material of the application has the characteristics of large specific surface area, large pore volume, low surface polarity, low cost and the like, which can realize high selectivity and rapid screening separation of target components in HMF and fructose mixed solution, and has very broad application prospect in the field of fructose purification.

This utility model discloses an activated carbon decolorization device for fructose syrup, belonging to the field of fructose syrup processing technology. It includes a mixing tank, with a drive motor located at the upper center of the mixing tank. The drive motor's shaft is connected to a stirring rod. A feed pipe is located on one side of the upper end of the mixing tank, and a filling pipe is located on the other side. A fixed base is installed at the bottom of the mixing tank, and a filter assembly is installed at the lower end of the fixed base. A discharge pipe is installed at the lower side of the filter assembly. In this utility model, the adsorbed activated carbon particles fall into a filter basket. A stepper motor rotates, driving a protrusion to rotate. The protrusion pushes a limiting plate, which in turn pushes a connecting rod to move, causing the filter basket to move upwards. Due to the gravity of the filter basket and the elastic force of the return spring, the filter basket vibrates back and forth, preventing activated carbon particles from clogging and affecting the discharge of fructose syrup, thus ensuring the filtration effect.

A lactulose solution end treatment device belongs to the technical field of lactulose production related equipment, and includes a curtain type membrane solid-liquid separation device for separating aluminum hydroxide from raw material liquid, and the interception capacity of the curtain type membrane solid-liquid separation device is configured to intercept aluminum hydroxide flocculation and allow lactulose molecules to pass through. The curtain type membrane solid-liquid separation device is used to realize the filtration and separation of aluminum hydroxide, and the advantage is that the interception capacity of the organic membrane in the curtain type membrane solid-liquid separation device can make the lactulose molecules pass through, and the aluminum hydroxide flocculation is intercepted, so that the separation of the lactulose raw material liquid is realized. The lactulose solution end treatment device provided by the utility model can realize efficient separation of aluminum hydroxide in the raw material liquid, and improve the final yield of lactulose.
