The Process (Drying) Cycle
Process air from the hopper is pulled into the dryer, through the process filter and then into
the process blower inlet. Air exits the process blower and then enters the aftercooler, then
passes through the desiccant wheel, where moisture is removed. The air exits the dryer and
passes through the precooler (if installed), then into the delivery air heat source (Heater Pack,
HTC, or GasTrac). After the air exits the delivery air heat source it then goes into the hopper
inlet through internal piping, then to the spreader cone, which evenly distributes the air
through the material.
The Cooling Cycle
(All models except D2400, D4000 and D5000)
Regenerated desiccant must be cooled before it rotates back into the process cycle. The
process blower pushes the process air through the desiccant wheel. A small amount of the
process air is diverted through a small section of the desiccant wheel to cool the air. The
cooling air then returns back to the process air stream at the start of the process cycle.
The Regeneration Cycle
The regeneration blower pulls air through the regeneration filter into the dryer’s regeneration
heater. The air is heated to 350°F {177°C} before it is pushed into the “wet” section of the
desiccant wheel. The hot air purges moisture from the desiccant. The moist air is blown out
the moisture exhaust at the top of the dryer.
