Factors to be considered in the selection of thin film evaporators

      The thin film evaporator is a type of evaporator, which is characterized in that the material liquid flows in the form of a film along the wall of the heating tube for heat transfer and evaporation. The advantages are high heat transfer efficiency, fast evaporation speed and short residence time of the material, so it is particularly suitable for heat sensitivity. Evaporation of matter. In the selection of thin film evaporators, various factors must be considered:
1. Production capacity and operating parameters: including treatment volume, inlet and outlet concentration, temperature, annual operation hours, etc.;
2, product characteristics: including heat sensitivity, viscosity and fluidity (at operating temperature), foaming, solid content, crystallization and polymerization tendency;
3. Operating medium: such as water vapor (pressure), cooling water (temperature), cleaning solution (solvent), etc.;
4. Material selection and surface polishing requirements for manufacturing;
5. Site conditions: such as space, climate (outdoor), energy and product connection, work platform, etc.
