DRYING COATING LAYER WITH INERT FITTINGS Russian patent published in 2018 - IPC F26B17/10 F26B3/12 F26B3/88 

FIELD: technological processes.

SUBSTANCE: invention relates to a technique of disperse material drying in a fluidized bed and may be used in aniline-color, food, pharmaceutical, microbiological, food, chemical and other industries. Fluidized bed drier with an inert packing contains a body consisting of a cylindrical and conical parts, in which the gas distribution lattice and the solution and coolant supply systems are located, the dryer further comprises inert bodies and a baffle for cleaning inert bodies, made in the form of a perforated grille fixed in the place of transition of the cylindrical part of the body into the conical part. Inertial nozzle is made in the form of a cylindrical ring, on the lateral inner surface of which there are fixed partitions in the form of holes perpendicular to the axis of the ring of washers whose axes are asymmetric to the axis of the ring, or an inert nozzle is made in the form of a block inscribed in a circle, consisting of seven interconnected side edges of hexagonal parallelepipeds without an upper and a lower base, or an inert nozzle is made in the form of interconnected helical spirals, inscribed in a spherical surface with a center lying on the axis of the connection of the spirals, or an inert nozzle is made in the form of at least twelve connected three-bladed propellers, the projection of which on the plane of the drawing is inscribed in a circle with a center coinciding with the center of one of them.

EFFECT: increase in drying performance.
