Patent ID: 7089683

Claim:
A drying device for removing moisture from moisture-containing materials placed inside the drying device, the drying device comprising: a) a kiln compartment ( 1 ), having a plurality of side walls ( 11 , 12 , 13 , 14 ), a top wall ( 100 ), and a bottom wall ( 101 ), that define a kiln volume ( 6 ), for holding material to be dried, the kiln compartment ( 1 ) further having at least one loading door ( 131 ) through which the material to be dried is placed into the kiln compartment ( 1 ); b) at least one system vent ( 111 ), movably positioned in at least one side wall ( 11 , 12 , 13 , 14 ), and communicating between the kiln compartment ( 1 ) and the exterior of the drying device; c) a heat condensation device ( 2 ), including a housing ( 20 ), containing a condensation unit ( 21 ), a heating unit ( 22 ), and at least one ventilator ( 25 ), positioned in at least one side wall ( 11 , 12 , 13 , 14 ) opposite to and different from the side wall ( 11 , 12 , 13 , 14 ) in which the at least one system vent ( 111 ) is positioned; d) an air deflector ( 3 ), positioned in an upper zone of the kiln volume ( 6 ) in the kiln compartment ( 1 ); e) a tunnel-shaped air shaft ( 1000 ), extending horizontally along the kiln compartment ( 1 ) proximate to the top wall ( 100 ), and forming an air passage ( 30 ) between the air deflector ( 3 ) and the system vent ( 111 ); and f) a ventilation unit ( 40 ), positioned in the tunnel-shaped air shaft ( 1000 ), for drawing air into the tunnel-shaped air shaft ( 1000 ); such that a volume of dry air is circulated in the kiln compartment ( 1 ) by a plurality of ventilators to absorb moisture from the material to be dried.
