Flash Drying Process. Wet material is dispersed into a stream of heated air (or gas) which conveys it through a drying duct. Using the heat from the airstream, the material dries as it is conveyed. Product is separated using cyclones, and/or bag filters.
The logical extension of this technique is total dispersion drying, i.e., flash or pneumatic dryers, fluid beds, etc. where discrete particles can be brought into contact with the hot gas. This produces rapid heat transfer with correspondingly short drying times. Batch type fluidized bed dryers have, therefore, superseded forced convection
