The '''Ribbon Dryers''' require low capital cost because drying is completed in the same time and vessel is used for transferring and mixing. The ribbon dryer can be applied for low temperature drying, reaction, crystallization, extraction of useful liquids and recovery of solvents. | The '''Ribbon Dryers''' require low capital cost because drying is completed in the same time and vessel is used for transferring and mixing.

The Ribbon dryer provides conductive heating of materials through a thermal fluid jacket on the mixing vessel resulting in a flash evaporation of volatile components such as water or organic solvents. The material agitation or transfer exposes the material to the open space at the top of the mixer. In order to continue to drive the evaporation, the vapor in this free space is removed either by the assistance of a conventional fan or by convection. | The Ribbon dryer provides conductive heating of materials through a thermal fluid jacket on the mixing vessel resulting in a flash evaporation of volatile components such as water or organic solvents.
