Abstract

The invention discloses a method for preparing a natural salt by using seawater. The method for preparing a natural salt by using seawater comprises the following steps: water purification: filteringsaline water to remove impurities included in the saline water; ozone sterilization, supplying ozone to the saline water for sterilization; crystallization: spraying the saline water onto a salt crystallization plate and carrying out heating so as to form a salt by crystallization; moisture drying: removing moisture in the crystallized salt through drying; and foreign matter removal: removing foreign matters from the above crystallized salt.

Description

technical field [0001] The invention relates to a method for preparing natural salt using seawater. Background technique [0002] The chemical name of commonly used salt is sodium chloride (NaCl), and salt is divided into edible salt and industrial salt. The above-mentioned edible salt is widely used in daily life such as seasoning of food at home or production or processing of pickled food, and industrial salt is widely used in various industrial fields. [0003] Salt is prepared from seawater, mineral salt, salt lake or underground salt water, and can be divided into sea salt, mineral salt, refined salt or refined salt according to the production method. Mineral salt accounts for 2 / 3 of the world's consumption, but sea salt, such as sea salt, is favored and widely used due to the advancement of dietary life and increased health concerns. [0004] Sea salt is produced on tidal flats in a natural state. Sea salt is attracting attention as a scarce resource worldwide, and t...
