VENTURI DISPERSING FEEDER Abstract of the Disclosure A Venturi dispersing feeder particularly suited for utilization as part of a flash drying system, and through the operation of which wet material is introduced into a hot gas stream far purposes of effecting the rapid evaporation of the moisture in the material. The subject Venturi dispersing feeder includes a feeder body, which functions as a housing for rotor means. The latter rotor means is equipped with a multiplicity of blade means suitably mounted thereon for rotation therewith. The feeder body further has formed therein inlet means, connec- table in fluid flow relation with a source of wet material and operable for feeding the wet material therethrough into the feeder body,and outlet means, connectable in fluid flow relation with a stream of hot gases and operable for discharging the wet material from the feeder body into the stream of hot gases in substantially parallel relation to the path of flow of the latter. The feed inlet means and the discharge outlet means are each oriented relative to the major axis of the feeder body so as to bear a tangential relationship to the path of rotation of the blades means that are mounted on the rotor means. Through the action of the blade means, the wet material entering the feeder body through the feed inlet means is mixed therein, and agglomerates contained in the wet material are disintegrated. Thereafter, the wet material is discharged from the feeder at a high velocity in a non-agglomerated form through the discharge outlet means thereof into the path of flow of the stream of hot gases whereupon, in the presence of the hot gases, rapid flash drying of the wet material takes place. The feeder body is suitably supported on a base. The latter base is provided with adjustment means operative for effecting adjustments in the angle of discharge of the wet material from the discharge outlet means relative to the path of flow of the stream of hot gases so that the wet material leaving the discharge outlet means can be made, through adjustments in the angle of discharge thereof, to enter the hot gas stream with the desired orientation relative thereto, C780820 i.e., in substantially parallel relation to the path of flow thereof and in coincident relation therewith.
