Abstract

A dryer, especially suitable for wood, comprises a vessel which can be closed, carrying a flow of air through the wood. A vacuum pump is connected to the vessel. There is a heater on the air inlet, and the vessel is followed by a condenser. The air circuit is coupled to a closed coolant circuit (48) of a refrigeration machine, of which an evaporator (46) serves as a water condenser (44), and which is connected via a compressor (66) with a further, coolant circuit condenser (64), which forms part of the heating unit. Preferably, condensed water is collected (52, 56) outside the drying vessel. A spray tube (40) is provided to moisten the wood in the vessel (18), and a blower circulates the air (24).
