Artisan Industries' Rototherm Mini is designed for continuous lab-scale operations.

Artisan Industries’ Rototherm Mini is a continuous lab-scale evaporator and dryer. Utilizing the same thin-film separation technology as the company’s production-scale evaporators, the mini is designed for continuous evaporation and liquid-to-powder drying of heat sensitive materials. The device has a 5 mL/min–50 mL/min feed rate and a maximum operating temperature of 450 °F.

The mini features a high-speed rotor that uses centrifugal force to create an agitated thin film. Relative to traditional wiped-film evaporators, this enables the processing of viscous or foaming liquids and slurries. The stainless-steel, fixed-clearance rotator is designed for easier cleaning.

Additionally, the device has a horizontal orientation, allowing researchers complete control over residence time. This capability is intended to enable liquid-to-powder drying in a single pass and improve product yield.
