6.4. Hopper heaters (optional)
If differing drying temperatures are required in the different drying hoppers, hopper heaters must be installed on the drying hoppers. The drying temperature of each drying hopper can be set cen- trally at the dryer.
6.5. Automatic motor flaps (optional)
Automatic motor flaps cut off the drying hopper from the drying circuit as soon as the material is completely dried. The supplementary heating system is also switched off. Dehumidified air flows into the drying hopper only after new, moist material is added to the hopper. This ensures that the material is not damaged, and saves a considerable amount of energy.
Temperature probes at the feed opening of the drying hopper and inside the drying hopper enable comparison of feed opening and material temperature, from which the drying degree of the mate- rial can be calculated.
If the drying hopper is to be cleaned or blocked, the motor flap can be closed via the dryer. The supplementary heating system is then automatically switched off.
6.6. Connection to a pneumatic conveying system (optional)
The dryer operates most effectively in conjunction with a pneumatic conveying system. This com- bination of dryer and conveying system ensures that sufficient material is always fed into the dry- ing hopper.
Only the amount of material required for the processing machines used is removed from the hop- per. This guarantees that the final drying result remains constant.
Sterling drying hoppers are available equipped with the corresponding flange for connection of a Sterling pneumatic conveyor directly ex works.
Suction boxes can also be delivered with the required number of suction tubes. These suction bo- xes were developed specially for this hopper to prevent dust and foreign particles from being aspi- rated into the system.
Adevice for connection to the dehumidified air supply line is also available. Please note that the function of this combination is different from that of the conventional Sterling suction boxes.
