Description of function
The instrument is an accessory for BUCHI Spray Drying Instruments. It enables the
safe use of organic solvents in closed loop mode.
The spray drying process in closed loop mode generates an inert gas stream loaded
with solvent vapors. The instrument is used to condense these solvent vapors from
the gas stream and to monitor its oxygen concentration.
The gas flow enters the instrument and passes the pre-heat exchanger where it is
cooled before entering the condenser. After solvent vapor condensation, the gas
stream is reheated by the pre-heater before being returned to the spray drying
process. The excess inert gas leaves the instrument via the exhaust and the
condensed solvent vapors are collected in a closed bottle.
The following spray drying modes are available:
Spray drying mode
Solvent composition
Closed mode with Inert Loop
(When using Ultrasonic Package acces-
sory inert gas adapter is necessary)
between 90 % - 100 % organic solvent
Closed mode with Inert Loop and Dehu-
midifier
(When using Ultrasonic Package acces-
sory inert gas adapter is necessary)
between 20 % - 80 % organic solvent
