Closed cycle spray drying in the drying chamber will be sealed into
the mist droplets dispersed solid to liquid and hot medium
(nitrogen N2) was dried droplet method of powder products. Atomized
by rotary atomizer or a nozzle atomizer to achieve, droplet drying
can be adjusted by the temperature or the flow of heat medium to be
controlled, evaporation of the solvent to be recovered through the
condensation unit, after "removal" and full " dewetting "of the
media were highly efficient filters and returned to heat exchanger,
and finally recycled into the drying system. The success of closed
cycle spray drying washing and cooling operation requirements will
be part of an accurate temperature control. For high boiling point
of alcohol generally cooling water or salt water, low boiling point
solvents such as dichloromethane, hexane, acetone and the like, you
must use compression refrigeration system heat exchange
