PLENUM DRYING HOPPER WITH INTEGRAL HEATERS Abstract of the Disclosure A plenum drying hopper for granular material includes a housing enclosing a plenum chamber, an upper material inlet for introducing a flow of granular material into the plenum chamber, and a perforate diffuser cone, located in the lower portion of the plenum chamber, that directs the granular mater- ial from the plenum chamber into a material outlet. The per- forations in the diffuser cone are large enough to permit ready passage of gas therethrough but small enough to preclude passage of all but the finest particles of the granular material. A gas inlet extends into the lower portion of the housing for intro- ducing a drying gas (air) into the plenum chamber; a gas outlet discharges the gas from the upper part of the housing. Heaters are provided for heating the gas prior to its entry into the plenum chamber. The improvement comprises a deflection shield structure mounted in the housing below the plenum chamber between the heaters and the diffuser cone, that directs heated air along a labyrinthine path from the heaters through the diffuser cone and into the plenum chamber. It also shields the diffuser cone from the heaters to prevent radiant heat from reaching the diffuser cone, and deflects fine particles of the granular material that pass through the diffuser cone directly into the material outlet.
