<p>A method for producing re-crystallized salts is provided to reduce markedly an energy cost required for producing re-crystallized salts by heating a salt solution in advance using a heat pump. A method for producing re-crystallized salts using a heat pump includes the steps of: charging salts and water into a tank(1) to obtain a salt solution; supplying heat generated from the heat pump(3) to the tank to heat the salt solution to predetermined temperature; sending the heated salt solution to a heating tank(2); and heating the salt solution to 100 °C or higher, and then cooling the salt solution to obtain the re-crystallized salts.</p> |
