ABSTRACT:
Material to be treated is transported through a treatment zone bounded by a foraminous member that separates the treatment zone from an immediately adjacent zone of high density vapor. The vapor is flowed through the foraminous member and directly into the material at a continuous rate and with a major portion of the vapor flowed from the vapor zone being entrained by the material in the treatment zone. The continuous moderate flow of vapor into the bed of material produces rapid vapor transfer and with excellent distribution of the vapor within the material being treated.
