Process Intensification for Drying and Dewatering

Abstract

Background information on process intensification including the rationale, basic methods in process engineering, and interactions between material streams and processing methods is given. The general rules are then examined with respect to heat and mass transfer intensification, and pertinent to drying techniques and technologies (e.g., microwave drying, pulse combustion drying, intermittent drying, drying by alternation pressure, etc.) are highlighted. Milk processing for powdery product and bakery production is given as an example of process intensification with respect to water evaporation.
