Rising Film Evaporators are designed for efficient preheating and preconcentration of materials in various applications.
Artisan designs and manufactures rising film evaporators at our facility in Stoughton, MA, offering various customizations depending on customer requirements.
Feed enters the evaporator tube-side from the bottom, where it is heated to form a rising film on the tube wall. Most of the tube cross-section fills with vapor. The ascending vapor bubbles carry the liquid and vapor upwards in a parallel flow. This upward movement creates turbulence in the liquid, which is advantageous during evaporation of highly viscous materials and products that have a tendency to foul the heat transfer surfaces.
