11.8 Description of heating profiles
4 heating profiles are available, as follows:
• Standard
• Fast
• Soft
• Step-by-step drying
Standard drying
Standard drying is the most frequently used drying
process. This type of heating method is suitable for
the majority of substances.
Soft drying
The soft heating method is suitable for substances
that are unable to tolerate a sudden rise in
temperature applied by radiators. There are also
those substances that form a film when warmed up
quickly. This film will afterwards affect the
evaporation of the enclosed moisture. For such
substances, the soft mode of warming is equally
suitable.
Fast drying
The fast heating profile is suitable for samples with
a moisture content of 5% to15%. The temperature is
increased very quickly and, for a short while, will
exceed the set drying temperature. After that the
temperature will be adjusted down to the set value.
The sample must contain enough moisture.
Step-by-step drying
Step-by-step drying is suitable for substances that
display special behaviour during warming. The
individual steps are freely selectable regards
duration and temperature rising step. Samples
should have a moisture content of at least 15%.
