The DM can be used to determine when successful drying is underway and processing of
material can begin, using the following guidelines:
●
See Operation:Setting Up Your DM: The Basics-Alarm Location
"alarm location" sensor for your drying system (this is typically T3 or T4).
The alarm location sensor can be used to determine when the hopper's material has
●
been sufficiently exposed to proper drying temperature for the proper length of time
(residence time) and processing of the material in the hopper can begin.
●
Processing can begin when the alarm location sensor (typically T3 or T4) has stabilized
at the drying temperature setpoint for approximately 50% of the required residence
time.
Example: If the material drying temperature is 250°F and the required residence time
is 4 hours, once the alarm location sensor has displayed 250°F for 2 hours (50% of 4
hours), processing can begin.
In normal operation, T1 will read closest to the process air temperature.
