Problems solved by technology
Vesicular mesoporous silica obtained by using single-template DDAB is easy to aggregate, unstable in structure, and single in shape, which limits its application
[0004] The existing production process needs to repeatedly adjust the pH value, and the obtained vesicular mesoporous silica aggregates seriously and has a single shape, the number of layers cannot be adjusted according to specific applications, and the prepared vesicular mesoporous silica Silicon oxide is a single layer with uneven particle size distribution

The invention provides a mesoporous silica synthesis device for food detection, belongs to the technical field of food detection, and solves the technical problems that mesoporous silica is difficult to synthesize quickly and efficiently and the like. Comprising a swing mechanism, a conveying dryer, a grinding mechanism, an elevator, a feeding high-temperature furnace, an air cooling box and a conveyor which are sequentially arranged, a distillation mechanism, a stirring tank and a quantitative injection mechanism are arranged on the swing mechanism, the distillation mechanism is connected with the stirring tank through a pipeline, and a washing mechanism, a standing mechanism and a first fan are arranged on the conveying dryer; a suction filter is arranged between the washing mechanism and the standing mechanism, a material injection pump is arranged between the stirring tank and the standing mechanism, temperature control sensing alarm lamps are arranged on the conveying dryer and the feeding high-temperature furnace, and a second fan is arranged above the air cooling box. Assembly line work can be achieved, stirring is efficient, mixing is sufficient, raw materials can be rapidly and quantitatively injected, efficiency is high, and the effect is good; and air cooling can be effectively carried out to obtain normal-temperature mesoporous silicon dioxide which is convenient for subsequent use.
Description
technical field [0001] The invention belongs to the technical field of food detection, and relates to a mesoporous silica synthesis device for food detection. Background technique [0002] Mesoporous materials are widely used in biocatalysis, chemisorption, controlled drug release, sensors, and color separation. Aggregates formed by surfactant molecules (such as micelles, vesicles, liquid crystals, etc.) are used as templates. Through polycondensation, assembly, and shaping of precursors, calcination or organic solvents are used to remove template agents, and ordered structures with different morphologies can be synthesized. Mesoporous materials, such as rods, microspheres, fibers, lamellae, raspberries, vesicles, etc. [0003] In recent years, the potential application of vesicular silica materials in the field of food detection has attracted more and more attention. Unique mesoporous structure, huge specific surface area, high mechanical and thermal stability, high poros...
