The invention concerns a vortex machine modified to intensify the vortex in the machine by installing inlet fans in addition to the main fan and modifying the configuration of the machine. Additional intensification of the vortex is achieved by introducing microwaves into the vortex machine. The vortex machine has a vortex tube, an inlet tube to the vortex tube at the inlet end, a feed inlet to the vortex tube between the inlet end and an outlet end and a fan rotor at the outlet en to draw air in a vortex through the vortex tube. An inlet fan in the inlet tube adapted to force air into the vortex tube. These modifications and additions achieve commercially viable capacities of the vortex machine in drying, grinding and process applications.
