Spray
drying is a process in which a liquid containing dissolved or suspended solids
is sprayed through a nozzle into a chamber in which hot air is being blown into
at the same time. As the nozzle releases small drops of the solution, it comes
in contact with the hot air and the moisture content of each droplet is
removed. This way, the liquid is turned to powder form which moves to a conveyor belt at
the bottom of the chamber.
