Dehydration – spray dryers (single and multi-stage driers)

Involves the atomization of a feed solution, slurry, or emulsion containing one or more components of the desired product into droplets by spraying followed by the rapid evaporation of the sprayed droplets into solid powder by hot air/gas at a certain temperature and pressure.
This is the preferred method of drying for many thermally sensitive materials. Produces a powder or concentrate from liquid feed solution. Can be used to encapsulate flavours by entrapping the core with an edible shell.
