time. Too high drying temperature causes burning of dried sample (sample overheating,
chemical decomposition). Drying temperature of traditional method (using a furnace) is
specified in applicable industry or company standards. Unless standards apply, then
temperature should be adjusted by tests.
On selecting the value of drying temperature, use the following procedure:
• Determine moisture content in a sample
• Determine temperature of substance chemical decomposition by tests
• Compare result obtained on a moisture analyzer with the one of traditional
method
When drying a sample with high humidity
content, it is possible to shorten
measurement time by selecting “Step” or
“Quick” drying mode. In such case, the
majority of moisture content is released
when drying temperature higher than set.
Only after some time, the temperature is
lowered to the set value, and maintained
until completing drying process.
13.4. Selecting a drying mode
The software of moisture analyzer MAX series enables selecting one of four
drying modes:
• Standard
• Quick
• Mild
• Step
STANDARD mode
Standard mode is the most frequently used of all
drying modes. It enables accurate determining of
moisture content is a dried sample
.
MILD mode
Mild mode is used in case of drying substances that
are sensitive to rapid heat emitted by filaments
operating at full power in the initial stage of drying
process. This mode prevents from decomposing of
substances sensitive to heat by mild temperature
increase in set amount of time (time interval has to be
selected by tests). Mild mode is recommended to
drying samples of leather structure.
QUICK mode
Quick mode is recommended to drying samples that
moisture content varies from 5%, and 15%. In the
initial stage of Quick mode, heating takes place at full
power of the filaments, causing heating the drying
chamber to increased temperature (maximum
temperature value is higher by 30 % from set drying
