Abstract

The invention relates to drying and can be used in the food and chemical industries. The purpose of the invention is to intensify the drying process. The installation contains a cylindrical vortex chamber 1 with a tangential nozzle 2 for introducing a peripheral flow of a gas suspension, under which a separation chamber 3 is tapered tapering downwards with a nozzle 4 for introducing a central flow. Inside the vortex chamber 1 there is additionally installed along its entire height a coaxial annular insert 7 with a notch in the zone of the tangential nozzle 2. On the edges of the insert 7 are articulated guide pivoting plates that overlap one another and form a variable section nozzle during rotation of the gas suspension. 1 hp ff, 4 ill.
