| description | PROBLEM TO BE SOLVED: To provide a method and an apparatus for manufacturing salt having the same quality as that manufactured by sun-drying in a short time at a low cost in the same way as industrially manufactured by an ion-exchange membrane method or the like. SOLUTION: The salt is manufactured by heating seawater at a temperature ≤80°C under a reduced pressure to concentrate by 8-10 times, separating its solid part and liquid part, further concentrating the liquid part by 2-3 times, and then depositing the salt. The apparatus for manufacturing salt is equipped with a concentrating apparatus to concentrate seawater, which comprises a concentration tank to accommodate seawater, a decompressing means to decompress the concentration tank, a stirring means to stir the seawater in the concentration tank, and a heating means to heat the seawater in the concentration tank. The heating means comprises a water tube installed in the concentration tank, a pump to circulate a liquid in the water tube, and a heater to heat the liquid in the water tube.
