Thermo-sensitive powder drying - a novel approach utilizing thin film evaporators to enhance (or replace) spray dryers

Abstract: Spray drying of thermo-sensitive materials can involve both high capital equipment costs and high operating costs for processors manufacturing powders. This talk will describe a novel approach utilizing thin film evaporators to enhance spray dryers' performance.  In some cases the thin film evaporator can fully replace spray dryers.
Major principals of horizontal TFE operation and how they apply to drying applications will be covered. The features of horizontal TFE will be compared to spray dryers. Energy use and efficiency will be compared as well. Case studies that focus on temperature sensitive applications will be presented.

Some of the cases to be presented include:

    Concentrating and drying Active Pharmaceutical Ingredients (APIs), intermediates and nutraceuticals
    Continuous drying of heat sensitive liquids or slurries to free-flowing powders in a single pass such as:
    * Plant / Animal Proteins
    * Isoflavones
    * Dairy Products
    * Starch & Fiber
    * Fermentation Products
