ABSTRACT:
A hot air drier system for breaking up and drying particles or aggregates of moist material includes a preliminary drier unit with a moist solids inlet, a hot air inlet, and a dried solids outlet. A pneumatic conveying conduit receives solids from the outlet and subjects them to further drying while they are conveyed to a suitable separator. Hot air is supplied to the drier inlet through a supply conduit which has a bypass conduit for delivering fully heated air to the pneumatic conveying conduit close to the solids outlet and which also has a cooling air conduit or bypass for selectively feeding heated air of somewhat lower temperature to the drier inlet.
Details of a preferred drier unit include the relative location of the moist solids inlet directly above a hot air inlet at the bottom of the drier and with at least one sloping side wall of the drier inclined upwardly and outwardly to a solids outlet opening in the top wall at a location laterally offset from the vertical axis of the solids inlet and hot air inlet. Heated air from the air supply conduit is fed into a cylindrical plenum chamber below the bottom air inlet of the drier unit. A rotary rake member within the unit assists in breaking up and lifting moist particles dropping through the solids inlet toward the bottom air inlet. The rake member, drier cross-section, and upward flow of heated air recycle particles in the drier unit, until they are sufficiently broken up and dried for air classification and delivery through the solids outlet opening.
