A drier (10) adapted to provide countercurrent contact between particulate matter and a relatively drier gas is disclosed, the drier (10) comprising a plurality of circumferentially spaced gas discharge outlets (26) and a centrally disposed, corrugated frustoconical separator (32) comprising a plurality of apertures (38) through which the particulate matter and gas must pass while flowing in substantially opposite directions through the drier (10). |
