Abstract
The device relates to a wood drying plant comprising a wood drying device and a purifying device which is arranged to receive a drying gas from the wood drying device, the drying gas comprising water steam and volatilized organic components such as terpenes, and to purify the drying gas from organic components and to recover the latter. The purifying device comprises at least one condenser which is arranged to separate relatively difficultly volatilized components containing organic components and relatively easily volatilized components. The purifying device also comprises a separating device which is arranged to separate said organic components and a rest material from the relatively difficultly volatilized components. The purifying device also comprises a transferring device which is arranged to transfer organic components present in the rest material to the drying gas introduced in the purifying device.
