ROTOTHERM® MINI

Artisan ROTOTHERM® MINI is Production-Scale Technology at Lab Scale

The Rototherm® Mini brings Artisan’s proven horizontal thin-film evaporation technology to research and development teams who need continuous, scalable separation without committing to full production equipment. It utilizes the same core technology and operating principles as Artisan’s production-scale ROTOTHERM® units, allowing teams to generate process data that translates directly to commercial scale.

Manufactured in Massachusetts, the MINI is designed for easy installation, maintenance, and cleaning, with a small footprint and a high turndown ratio of 10:1 that makes it adaptable across a wide range of feed rates and applications. For facilities seeking a more complete processing platform, the ROTOTHERM® MINI System arrives fully assembled on a compact, mobile cart with the supporting equipment, piping, and instrumentation needed to begin process development quickly.

Key Features

What Makes the ROTOTHERM® MINI Different

Horizontal Orientation

Up to 99% evaporation of liquids, slurries, or viscous materials for higher yields without dry spots or fouling, with the capability to achieve liquid-to-powder drying in a single pass. Its horizontal orientation also provides greater control over residence time.

Robust Construction

Versatile with the ability to handle high viscosity materials and produce dry materials. Stainless steel construction that is easy to assemble, disassemble, and clean.

Preserve Product Quality

Avoid degradation on heat-sensitive materials with the combination of short residence time, vacuum operation, and reduced processing time compared to batch operations.

Scalable

Continuous process can reliably scale to commercial production equipment utilizing proven Rototherm® thin-film separation technology.

Plug-and-Play System Option

For laboratories and pilot plants, the Rototherm® Mini is supplied on a compact mobile cart with the essential equipment for evaporation, drying, and solvent-recovery development, eliminating the need to source and install separate components.

Technical Capabilities

The Rototherm® Mini is engineered for research and development teams that need continuous, reliable thin-film separation at bench scale. With a high turndown ratio of 10:1, a feed rate range of 5–50 ml/min, and the ability to process heat-sensitive and high-viscosity materials, the Mini delivers the core technical performance of Artisan’s production-scale thin-film evaporators in a compact, easy-to-maintain unit manufactured in Massachusetts. Its high-speed rotor creates an agitated, uniform thin film that supports controlled residence time and efficient processing of viscous, fouling-prone, or foaming materials.
