Abstract: A method of spray-drying liquid and pastelike materials which comprises atomization of liquid and pastelike materials and subjection thereof to shock wave action, atomization of the material being effected at the point of the maximum shock wave energy characteristic, i.e. amplitude and frequency. The installation for carrying said method into effect comprises a combustion chamber. According to the invention, a device for spraying the material to be dried is installed in the combustion chamber, the latter being connected with a resonance exhaust tube and separated therefrom by a screen made up of perforated elements.
