and chamber vacuum. Thus, the progress condition for switching to the
next section is fulfilled and the next section will be initiated.
If the condition for switching to the next section is not fulfilled, a process
message will be issued, the current section will be extended, and further
pressure increase tests will be executed periodically until the condition
is fulfilled. If the actual value exceeds the set value before the
preselected time has elapsed, the test will be aborted in order to
prevent the product from thawing.
• Periodic & progress condition:
This variant is a combination of the possibilities that are described
above. The test will be performed periodically during the entire main or
final drying phase. The maximum pressure increase is limited to 100%,
referring to the actual value at the beginning of the measurement. If the
actual value exceeds the set value before the preselected time has
elapsed, the test will be aborted in order to prevent the product from
thawing.
If, during both tests, the values of the pressure increase test are not
greater than the preset "Pressure increase" parameter, the drying
process will be considered complete at the current shelf temperature
and chamber vacuum. Thus, the progress condition for switching to the
next section is fulfilled and the next section will be initiated.
If the condition for switching to the next section is not fulfilled, a process
message will be issued, the current section will be extended, and further
pressure increase tests will be executed periodically until the condition
is fulfilled.
• Disabled:
No pressure increase test will be executed during the main or final
drying phase. There will be no evaluation.
