Rototherm, often referred to as thin film evaporation, utilizes a unique technique to optimize evaporation processes. This chapter delves deeper into the mechanics and advantages of this technology.

Mechanism of Rototherm Evaporation:

Rototherm evaporation relies on the principle of creating a thin, constantly agitated film of liquid on a heated surface. This thin film promotes rapid and efficient heat transfer, leading to swift evaporation.

Key Elements of Rototherm Evaporation:

• Thin Film Formation: The liquid is spread thinly across the heated surface, ensuring maximum contact area for heat transfer.
• Agitation: Constant agitation, often achieved through rotating blades, prevents the film from thickening, ensuring efficient evaporation and minimizing fouling.
• Heat Transfer: The thin film design allows for efficient heat transfer from the heated surface to the liquid, speeding up the evaporation process.
• Vacuum: In some applications, a vacuum is applied to lower the boiling point of the liquid, further enhancing evaporation efficiency.

Advantages of Rototherm Evaporation:

• High Evaporation Rates: The thin film design maximizes heat transfer, resulting in significantly faster evaporation rates compared to conventional methods.
• Gentle Evaporation: The constant agitation creates a gentle evaporation process, minimizing thermal degradation of heat-sensitive materials.
