A method of treating sea water or condensed sea water for producing salt, comprising the following steps of: providing a treating chamber having a roof and side walls, atomizing sea water into the treating chamber by scattering the sea water with use of a centrifugal generator, evaporating water components of the atomized sea water by blowing warm wind to the atomized sea water, arranging a first screen in one stage or a plurality of stages for passing the evaporated water components therethrough, said first screen is positioned below an opening provided at the roof of the treating chamber for exhausting the evaporated water components, adhering salt components to the first screen when the water components atomized by the rotation of the centrifugal generator and evaporated by the warm wind move upwardly toward the opening and pass through the first screen, and removing the adhered salt components by peeling and dropping the salt components from the first screen.
