DEVICE FOR DRYING WITHOUT CARRY-OVER Russian patent published in 2018 - IPC F26B17/10 F26B3/12 

FIELD: technological processes.

SUBSTANCE: invention relates to drying dispersed materials and can be used in microbiological, food, chemical and other industries. Apparatus for uncontaminated drying comprises a drying chamber, a fan, an exhaust air purification system. Supply of wet material or solution can be carried out by several atomizers (nozzles) uniformly located throughout the section of the shell, the heat carrier leaves the apparatus through the space below the top cover, atomizer (nozzle) of the initial product consists of a cylindrical body with a fitting rigidly connected to the body and coaxially disposed in the upper part of the body and having a cylindrical fluid inlet connected to a diffuser that is axisymmetric to the body and the fitting, in the lower part of the cylindrical hole, a hollow conical swirl is fixed, the conical shell of which is fixed by means of at least three spokes fixed at one end to the conical shell of the swirler in its upper part, and at other end – in the annular groove made on the inner surface of the cylindrical hole, on the outer surface of the hollow conical swirler a screw through thread is made, and to the body, in its lower part, by means of at least three spokes, another atomizer is connected perpendicular to the axis of the housing and is made in the form of a solid disk, the disk of the atomizer is formed by two surfaces, one of which is facing the diffuser, a curved surface, the line forming this surface being a curve of the n-th order, and the second is the plane, or the disk of the atomizer is formed by two congruent and equidistant surfaces of the n-th order, and the spokes, by which the disk of the sprayer is fixed to the body, are straight or curved in shape.

EFFECT: increased drying performance.
