Evaporator/Stripper™

Artisan Evaporator/Stripper™ Technology for Targeted Volatile Reduction

The Artisan Evaporator/Stripper™ is a falling-film column engineered to reduce volatile components in relatively non-volatile products to very low levels. Built for demanding materials that require short residence time, high vacuum capability, and controlled liquid/vapor contact, the Evaporator/Stripper™ offers a cost-effective approach for stripping volatiles from heat-sensitive,viscous, and solids-containing product streams.

Using a disc-and-tube tray design, the system repeatedly redistributes the falling liquid film as material cascades through the column. This repeated film renewal creates fresh surface area for heat and mass transfer, allowing volatiles to be removed efficiently while minimizing product hold-up, pressure drop, fouling, degradation, and discoloration.

Key Features

What Makes the Evaporator/Stripper™ Different

Repeated Thin-Film Renewal

Material flows over disc-and-tube trays as a continuously renewed falling film, creating fresh surface area for intimate liquid/vapor contact and improved stripping performance.

High Vacuum Operation

The Evaporator/Stripper™ is capable of operating at very low pressures, including below 1 mmHg absolute, helping reduce operating temperatures for heat-sensitive materials.

Multi-Stage Separation

Multiple stripping stages allow volatile components to be reduced to low ppm or ppb levels in a single pass, depending on the application and product requirements.

Low-Maintenance Design

With no moving parts, welded construction, and an unobstructed self-draining configuration, the unit supports reliable operation, easy cleaning, and multi-product processing, for consistent performance over decades

Technical Capabilities

The Artisan Evaporator/Stripper™ provides controlled volatile removal for applications that challenge conventional stripping equipment or vertical falling-film evaporators. The disc-and-tube construction repeatedly renews the falling liquid film, improving liquid/vapor contact and mass transfer while accommodating difficult feed characteristics such as viscosity, foaming, emulsions, dilute slurries, and solids content.

Where the Evaporator/Stripper™ Is Applied

Industries Served

Artisan Evaporator/Stripper™ Technology. Your Volatile Removal Application.

Applications involving solvent reduction, dehydration, deodorization, purification, recycling, or aroma recovery depend on feed behavior, volatile content, pressure conditions, and final product requirements. Artisan’s engineering team can evaluate those variables and identify whether the Evaporator/Stripper™ offers the right approach for controlled volatile removal.

Technology In Action

Feed is pumped to a pre-heater, where it is brought up to the bubble point of the volatile component at the operating pressure of the system. That heated material is then fed to the top of the Evaporator/Stripper, where it cascades down over a series of disc & tube trays, renewing the thin film as it flows down. A sparge gas/vapor is introduced at the bottom of the column, and flows up through the falling liquid, facilitating volatile removal. Trays can be heated to aid in stripping and vacuum can be used in the column to reduce operating temperature for heat sensitive materials. The stripped component vapor is condensed and collected overhead, while the remaining liquid that has been stripped continues to the bottom of the column where it is pumped out.
