The group of techniques comprising the standard spray
dryer equipment consists of: 1) a system of spray drying
of the material; 2) a system of heating and controlling the
temperature of the drying air; 3) a system of pumping and
controlling the flow of input of the material to be dried; 4)
a system of inputting air to be dried; 5) drying chamber
and 6) system of separating air – dried powder (Silveira
et al., 2013). The process can be described as the
pumping of the solution or suspension into the atomizer
(phase I), where it is sprayed in the form of a mist of
droplets (spray) into the drying chamber (phase II), where
the evaporation of the solvent occurs. That describes the
drying process through hot air, transforming liquid drops
into solid particles (phases III and IV), which are collected
in the cyclone filter or another dust collecting system
(phase V) (Filková and Mujumdar, 1995).
