摘要： Provided are an apparatus and method for manufacturing a solidified salt that is easy to treat in size and shape by using a vacuum transfer and a dual vessel. In the apparatus for quantitative solidification of a molten salt, a molten salt is introduced into a first vessel, and a second vessel is disposed inside the first vessel and quantitatively supplied with the molten salt. A molten-salt transferring unit quantitatively transfers the molten salt from the first vessel to the second vessel by vacuum pressure. A valve controls a discharge of the molten salt from the second vessel. A mold receives the molten salt from the second vessel and solidifies the molten salt. Accordingly, the molten salt can be stably discharged to the mold by quantitatively transferring the molten salt at vacuum pressure within the dual vessel, and a predetermined size and shape of the solidified salt can be manufactured, thereby processing and collecting the solidified salt safely.
