Operating instructions

6.3. Connection to a Pneumatic Conveying System (Optional)

Your drying facility works best in combination

with a pneumatic conveying system. In this

way, your drying hopper will always be supp

lied with sufficient material.

The facility will only take as much material as

is required by the processing machines. The

refore, the drying result will always be the

same.

Colortronic drying hoppers are equipped

with a suitable flange for adding a Colortronic

pneumatic conveyor.

Suction boxes with one or three suction tu

bes can be supplied as well (optional). These

suction boxes are developped specifically for

this type of hopper.

The loading of the conveying line with materi-

al is adjusted by closing or by opening of the

control cover (A).

6.4. Return Air Cooler (Optional)

A return air cooler must be employed if the return air temperature is hig

her 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 dry

ing cells.

The return air cooler can be connected to a coolant circuit or to the water mains network.
