Abstract
The invention relates to a drier-heat-exchanger for heat treating PET granulate and similar products. The drier has a channel which is delimited by air permeable sheets. This ensures that the product can pass through efficiently and evenly which in turn means that a higher gas speed can be used without the product being stirred up and therefore shorter heating times are possible.
