To develop an energy saving salt generator in which salt is generated without using heat energy such as a high temperature steam and a metal heated by a heater.

In a nozzle type salt generator, a low pressure fluid such as sea water in which a solid content such as a salt is dissolved is decomposed to 1-50 μm of a fine particle diameter by a high speed revolution air current generated by a high pressure gas that is supplied to a two-fluid nozzle that is formed by a metal or a resin, a property that the atomized fluid is effectively vaporized is utilized, and the solid content such as a salt that is dissolved in the inside is solidified without using energy by heat or the like.
