Method and apparatus for drying moist exhaust air from one or more bulk material drying hoppers

摘要

The exhaust air from a bulk material drying hopper is conveyed through a chamber filled with an absorbing medium and the air is fed back to the drying hopper in a closed circuit. The chamber is regenerated at intervals in a second circuit. The air throughput through the hopper is controlled as a function of the temperature of the exhaust air.
