Apparatus for drying cut wood has a cylindrical vessel with end covers at least one of which can be opened. The interior of the vessel is divided by a horizontal partition into a drying chamber above the partition, in which the wood is placed, and a condensation chamber below the partition. On opening in the partition provides restricted communication between the chambers. The interior of the vessel is filled with a drying medium made up of air and water vapour. A heater in the drying chamber heats the crying medium and a fan produces circulation of the drying medium in the drying chamber. The upper portion of the vessel wall, above the partition, is heat insulated while the lower portion, below the partition, is uninsulated and serves as a condenser for condensing water vapour in the condensation chamber. The lower portion of the vessel wall is cooled by cooling coils in a foundation which supports the vessel. In one embodiment, the wood is stacked on the load platform of a car which runs into the vessel through one end thereof, when open. The load platform of the car serves as the partition between the chambers. The operation of the apparatus is controlled by a microprocessor which has inputs connected with heat, pressure, and humidity sensors provided in the vessel.
