METHOD OF DISPERSE (BULK) MATERIALS CONTINUOUS DRYING INSIDE VERTICALLY MOUNTED ROTATING CONTAINER, HEATED FROM OUTSIDE BY RADIATION Russian patent published in 2016 - IPC F26B3/14 F26B3/20 F26B3/30 

FIELD: thermodynamics.

SUBSTANCE: invention relates to thermodynamics in terms of radiative heat exchange and to drying technology. In method of dispersed loose materials continuous drying inside vertically installed container it is heated from outside by radiation, and container is made perforated or from mesh and rotated relative to its fixed geometrical axis, and inside container pipe with radial blades on its outer surface is placed, coaxially to it and fixed with gap relative to container bottom and wall, wherein wet loose material is continuously supplied inside pipe, dried loose material is pneumatically removed from container. Container is made in form of thin-walled truncated cone installed vertically with smaller base downwards with obtuse angle between opposite generatrices of more than 100°, normally directing radiation on its side surface, and in lower cone opening thin-layer solid bottom in the form of segment of sphere of fluoroplastic convex part downwards is fixed relative to container, resting container on same shape fixed thrust heel, nine linear radiators of limited length, each in its reflector, are located stationary around container with uniform gap relative to it along generatrices and to each other, creating normally directed to container radiation flux in near infrared region, besides, flat blades fixed on pipe are made trapezoidal in plane, located along pipe in three uniform rows.

EFFECT: invention shall provide high uniformity of container side surface heating, method operation implementing device mounting and servicing.
