Generates the gas stream in the system. 100% re-

commended, so efﬁcient drying and best separation

is obtained.

For aqueous solutions, inlet temperatures are between

100 and 220°C. Lower range for heat sensitive product.

Typical set point 150°C.

By opening the needle valve on the ﬂow control, the

compressed air for the feed dispersion is set. Typical

level is 4 cm (approx. 600 l/h).

Close peristaltic pump bed. The process is started

with pure water to get the drying conditions . The outlet

temp. will decrease due to the consumption of energy

by the evaporation.

Typical set point of pump 30%.

The outlet temp. deﬁnes the maximal thermal load for

the product. Adjust inlet temp. and pump rate to obtain

a certain outlet temp. Lowering the aspirator rate will

also decrease the outlet temp.

In case of suspensions or product which tend to clog

the nozzle, the nozzle cleaning is switched on. Higher

number (2-9) means more cleaning pushes.

The spray drying starts as soon as the tube is switched

from pure water to product (by feed switch valve or

manually). The outlet temp. will slightly increase becau-

se less water has to be evaporated, eventually adjust

inlet temp.

Switch back to pure water to clean tube and nozzle.

Additional cleaning effect by drawing air bubbles.

Inert Loop starts to cool, both signal lamps are on (after

20 sec.). When starting the aspirator, pressure signal

lights off: gas stream is circulating. 100% recommen-

ded for efﬁcient drying and best separation in cyclone.

The set cooling temperature depends upon the solvent

used. For boiling point <70°, -20° is recommended, for

pure water, 10° must not be fallen below.

Nitrogen is fed into the cycle and the same volume is

leaving the system by the exhaust tube. The level of

oxygen is decreasing. If not, check tightness to ﬁnd

leakage.

The system is now under inert condi-tions; heater is

started. The procedure is equal as on the back side.

Inlet temp. approx. + 10°C above boiling point of sol-

vent.

Pure solvent is used to get the drying conditions. High-

er pump rates can be used, typical set point is 60%.

In case of suspensions or product which tend to clog

the nozzle, the nozzle cleaning is switched on. Higher

number (2-9) means more cleaning pushes.

The spray drying starts as soon as the tube is swit-

ched from solvent to product (by feed switch valve or

manually).

At the end of the process, switch back to pure solvent

to clean tube and nozzle. Additional cleaning effect by

air bubbles.
