A machine for heat treating granular, organic materials and primarily, though not exclusively, intended for such treatment of whole soybeans and corn, comprising a drum mounted for rotation within an elongated receiver, the drum being constructed and arranged to define, with a portion at the peripheral wall of the receiver, a peripheral series of pockets travelling with the drum, a fluid-fuel burner associated with the receiver and arranged to discharge, into a portion of the receiver in which the pockets are outwardly open, a longutidinally-extending, peripherally-restricted wall of flame impinging on said drum, the burner including flame guard means constructed and arranged to establish such a wall of flame, and means for driving the drum to cause such granular material to be moved rapidly and intermittently through the flame wall and in close proximity to the source of the infra-red energy.
