The present invention relates to a high-purity salt manufacturing apparatus using near infrared ray, which comprises: a chamber having a predetermined volume in which a salt inlet is formed on an upper part of one surface, and a high-purity manufactured salt outlet is formed on a lower part of the other surface; a plurality of salt heating units installed in a multi-step in the chamber with respect to a vertical direction, and continuously heating the salt supplied from the outside at high temperatures through the near infrared ray; a salt supplier for continuously supplying the salt to the salt heating units positioned in the uppermost end among the salt heating units in the chamber; a cooling path for slowly cooling the heat generated from the manufactured salt finally discharged through the salt heating units positioned in the bottommost end among the salt heating units in the chamber; a high-purity salt collector for collecting the manufactured salt discharged through the cooling path; and a control board for controlling the driving of the salt supplier, the salt heating units, and the cooling path, wherein the salt heating units installed in a multi-step with respect to a vertical direction is continuously installed to be crossed each other so that the salt outlet of the salt heating units positioned at the upper part is positioned at the upper part of the salt inlet of the salt heating units positioned at the lower part. Accordingly, the present invention can be installed even in a narrow space, and can continuously manufacture a large amount of the high-purity salt from which toxicity and impurities are removed at the same time, thereby not only improving productivity of the high-purity salt, but also remarkably reducing production costs of products. |
