FIELD: agriculture; mechanics. ^ SUBSTANCE: device contains the working chamber which top part is equal 1/3 of its general height and is executed in the form of the truncated cone with an angle at the top, equal 60, and the bottom part - in the form of the rotation paraboloid which bottom is executed bent in the chamber in a kind of torus surface with smoothly narrowed end, top and bottom air supply collectors, the last is connected with the gas supply device, gas outlet, located on the chamber axis which bottom part is executed in the form of the truncated cone, the unloading device in the form of the sedimentary chamber. The internal surface of the top and bottom parts of the working chamber, and also external surface of the gas outlet are executed in the form of the parabolas connected among them forming whirlers, and tops of parabolas of the chamber and the gas outlet are directed on the middle of the basis of an opposite parabola. ^ EFFECT: increase of efficiency of cooling of materials and decrease in power inputs on its cooling. ^ 1 dwg
