Abstract: A drying device is disclosed, which is created on the basis of many ventilation air systems arranged in a kiln compartment (1) and equipped with a heat condensation device (2) comprising a condensation unit (21) and a heating unit (22), and with at least one ventilator (25), with a kiln volume (6) as well as with at least one loading door (131) in the kiln compartment (1) where wood or other material for drying is placed with the help of carriage stacking units (5) with gradual absorption of moisture content in the wood to the circulating air available in the said kiln compartment (1) and particularly in the said kiln volume (6), at least one wall (11), which may also be arranged as a door, being equipped with a system vent (111), which in sense of functional leading of air flow for performing and monitoring the kind of drying mode in combination with an air deflector (3) placed above the kiln volume (6) in the kiln compartment (1) with the heat condensation device (2) ending in a certain distance from the another side wall (12) of the kiln compartment (1) close to the bottom (101) of the kiln compartment (1) to which also extends the said air deflector (3) close to the heat condensation device (2) equipped at least with one self-adjusting vent (31) and the air deflector (3) extending over the kiln volume (6) to the top (10) of the kiln compartment (1) in a direction towards the system vent (111) and the air passage (30) between the air deflector (3) and the said system vent (111) assembled in the wall respectively the door (11) of the kiln compartment (1) formed tunnel shaped air shaft (1000) in which is placed are appropriate ventilation assembly (40), characterized in that the system vent (111) is arranged in the wall respectively the door (11) of the kiln compartment (1) in such a manner that in its closed position internal circulation of the air flow is ensured from the tunnel-shaped air shaft (1000) in the area between the top (100) of the kiln compartment (1) and the air deflector (3) passing through the air passage (30) between the air deflector (3) and the wall respectively the door (11) into the kiln volume (6) in a direction towards the self adjustable vent (31) and under the air deflector (3) towards the heat condensation unit (2), and in the case when the system vent (111) is opened the air flow is passing from the tunnel shaped air shaft (1000) through at least two gaps formed by opening the open system vent (111) and the air is blown out of the kiln compartment (1) into open space on the upper side through at least one gap and simultaneously the fresh air is sucked from outside directly into the kiln volume (6) through at least one lower gap. This drying device could be used for drying any wood product regardless to dimensions, the construction of the kiln being of such proportions so as to fulfil dimensional and transport standards of transport containers, makes it possible to be used as a stationary or a mobile type.
