Functional description 6-22
6.3. Connection to a Pneumatic Conveying System (Optional)
Your dryer works best in combination with a
pneumatic conveying system. When
assembled this way, your drying hopper will
always be supplied with sufficient material.
The dryer will only take as much material as is
required by the processing machines.
Therefore, the drying result will remain
consistent.
Sterling drying hoppers are equipped with a
suitable flange for adding a Sterling pneumatic
conveyor.
Suction boxes with one or three suction tubes
can be supplied as well (optional). These
suction boxes are developed specifically for
this type of hopper.
The loading of material into the conveying line
is adjusted by closing or opening the control
cover (A).
6.4. Return Air Cooler (Optional)
) A RETURN AIR COOLER MUST BE EMPLOYED IF THE RETURN
AIR TEMPERATURE IS HIGHER THAN +65 °C (149°F).
A return air cooler improves the efficiency of the drying cells.
The lower the return air temperature, the better the efficiency of
the drying cells.
The return air cooler can be connected to a coolant circuit or to the water main network.
