ABSTRACT:
Method for producing salt grains in which the salt is dissolved in a liquid solvent inside a mixing tank so as to form a saline solution which is supersaturated with salt and which is then atomized inside a drying tower where a stream of hot air circulates; the atomizing process being designed to produce a plurality of drops of saline solution, all of approximately the same size, and the stream of hot air being designed to evaporate the liquid solvent contained in each drop so as to cause the salt present in the said drop to solidify into a salt grain of essentially spherical shape; given that the dimensions of the salt grains depend on the dimensions of the drops of saline solution, it is possible to obtain salt grains of the desired size by producing drops of saline solution of a suitable size during the atomizing process.
