SHF PLANT TO DRY LOOSE PRODUCTS Russian patent published in 1995 - IPC

FIELD: SHF equipment for electric treatment of products and dielectric materials. SUBSTANCE: SHF plant to dry loose products, predominantly vegetables and fruit, has heating chamber, multielement, conveyer, means to inject SHF energy and air. Heating chamber includes three heating sections placed in levels provided with belt conveyers with opposing motion. Alternating waveguide-slot radiators coupled to two groups of SHF generators equipped with ventilated cooling air ducts are placed above lower and upper conveyers in later a directions from side walls of chamber. SHF generators are also joined to coupling windows positioned in face wall of central heating section. Length of elements of waveguide-slot radiators should be not less than 1/2 width of heating chamber. EFFECT: improved functional efficiency. 3 cl, 3 dwg
