A process to prepare an edible liquid salt containing organic substances of biologic origin provides the extraction of seawater (101), which is subject to a preliminary filtration (102) for removing macroscopic substances such as algae and sand that can affect the correct operation of the apparatus used in the process. The filtered sea solution is then supplied to a vacuum evaporator (103), which works at a pressure lower that atmospheric, where a desired concentration is reached by boiling with consequent evaporation of the water surplus, until the concentration of sodium chloride (NaCl) is about 25%, which corresponds to a concentration of 9.8% in weight of sodium. The sea solution is then lead to a battery of filters (104) to purify further the final product by removing organic and inorganic substances with size higher than the substances of interest. The refined product is eventually sent to a bottling station (105). <IMAGE> |
