[0002] A thin film evaporator is a type of evaporator, characterized in that the liquid material flows in a film shape along the heating tube wall for heat transfer and evaporation. Its advantages are high heat transfer efficiency, fast evaporation speed, and short residence time of the material. Therefore, it is particularly suitable for the evaporation of heat-sensitive substances.

[0003] When the thin film evaporator is in use, the raw material needs to be injected into the interior of the evaporator. However, the concentration of the raw material to be evaporated is relatively high, which leads to a relatively large viscosity of the raw material. When directly filling, due to the large viscosity, the fluidity of the raw material is poor, resulting in uneven flow of the raw material inside the evaporator, thus affecting subsequent evaporation. Content of the Utility Model
