| Material from the inlet into the evaporator, the rotation of the distributor to the distribution in the cylinder wall of heating surface, scraper swing cloth into a thin and uniform of a membrane, and forced the formation of turbulence moves downward, absorbing jacket incoming heat, quickly evaporated and concentrated, concentrated liquid from the discharge port directly or through a cooler to enter receiver, system with vacuum pumping, two steam or solvent to the mist eliminator to remove entrained droplets and bubbles, by vacuum pumping pipe exhaust.

- With very high heat transfer coefficient scraper mobile film due to the rotor blade drive action, so that each piece of the scraper and the wall in front of the formation of vortex gap area. Vortex in the liquid constantly and liquid liquid on the heat transfer and exchange of heat transfer surface, constantly, constantly updated equipment, so that the heat transfer coefficient is very high.
- In a short heating residence time at the same time, also has a narrow time distribution, especially suitable for heat-sensitive materials concentration.
- Application of viscosity, export material on imported material viscosity ratio can reach above 1000 centipoises, see the table below for the treatment of several evaporator material viscosity range.
- Material flow time is short: blade surface with a certain angle groove pushes the liquid in the heating surface is helically and continuously move down and out of the heating surface. By using this method, the retention time is reduced to a minimum, eliminating the thermal decomposition, polymerization or metamorphism. Changing the rotational speed of the rotor or scraper grooves on the angle can be controlled retention time.
- Strong adaptability, convenient operation: since the film evaporator characteristics: suitable for stable evaporation and heat sensitive materials distillation. So the high viscosity material or with the increase of the concentration of the material viscosity increases dramatically, the evaporation process can be operated smoothly.
- Yield large regulation range, convenient operation, continuous production.
- Device for easy maintenance and repair.
