Abstract
A high-efficiency drying kiln, particularly for wood-like material, constituted by an internal chamber, which is covered with thermally insulating material and is provided with at least one opening for loading and extracting the material to be treated; two flues for recirculation of the air inside the chamber by aspirating and delivering air respectively from and into the outside environment; an air heating device; an air acceleration duct and air acceleration elements located inside the acceleration duct; the air acceleration duct has, at least at its output section, elements for orienting in an axial direction the air stream that is forced by the acceleration elements.
Claims19
A high-efficiency drying kiln comprising:
- at least one internal chamber, which is covered with thermally insulating material and is provided with at least one opening for loading and extracting a material to be treated,
- at least two flues for recirculation of the air inside said chamber by aspirating and delivering air respectively from and into the outside environment,
- at least one air heating device,
- at least one air acceleration duct arranged downstream of said air heating device, and
- air acceleration means located inside said acceleration duct;
- wherein said air acceleration duct has, at least at its output section, means for orienting in an axial direction an air stream that is forced by said acceleration means, said orienting means comprising a plurality of fins which are arranged in a grille pattern, so as to split the air stream downstream of said acceleration means into a plurality of parallel laminar portions.
A high-efficiency drying kiln comprising:
- at least one internal chamber, which is covered with thermally insulating material and is provided with at least one opening for loading and extracting a material to be treated,
- at least two flues for recirculation of the air inside said chamber by aspirating and delivering air respectively from and into the outside environment,
- at least one air heating device;
- at least one air acceleration duct;
- air acceleration means located inside said acceleration duct;
- said air acceleration duct having, at least at its output section, means for orienting in an axial direction an air stream that is forced by said acceleration means;
- an air channeling panel arranged at least at said output section of said acceleration duct and externally thereto;
- said at least one panel having means for air stream redirection and control inside said chamber;
- said redirection and control means comprising a widening of a free end of said panel in the form of a spoiler, having a cross-section shaped like a half ogive convex toward the outside.
