STT 1600

6.1. Dryer

The dryer operates with dehumidified air, i.e. the air is not only heated but also dehumidified before flowing into the drying hopper. This principle allows plastic granules to be dried to a residu- al moisture content as low as 0.002 % (PET granulate).

The dryer operates continuously, i.e. dehumidified and, if necessary, heated air is produced con- tinuously.

F

The dryer is designed for continuous operation.

The dryer operates with 4 drying cells; two of these cells are always in the drying cycle while the others are being regenerated (change-over after 3 hours).

If a malfunction occurs in the drying cycle during the program run, regeneration is not interrupted, but continues until the program end has been reached. This guarantees that 2 regenerated dry- ing cells are always available.

The air inside the switch cabinet is cooled by a cooling appliance for the protection of temperatu- re-sensitive components (if present, optional).

With the digital timer the dryer can be switched on and off at set times.

Dew point dependent regeneration switch (optional)

The dew point temperature is monitored continuously. The valve system switches to the freshly regenerated drying cells only after the selected dew point temperature has been reached. The hu- mid drying cells are then regenerated. After the cooling time the drying cells are ready for operati- on again. The valve system switches to the freshly regenerated drying cells only after the moistu- re content of the drying cells which are in the drying cycle have reached the setpoint value.
