摘要

In a timber drier, the packaged timber is circulated in a drying channel and has directed towards it a circulation air current. Above the drying channel is a circulation air channel which, at both ends, is connected to the ends of the drying channel. In the circulation air channel are fans which produce, apart from circulation air currents, both the input air flow and the output air current.
