Description

A manufacturing method for maintaining production of sea or solar salt throughout the year The present invention relates to edible salt, and in particular, enables the production of solar salt throughout the year while removing impurities or heavy metals that may be contained in the solar salt. The salt we consume today can be classified into chemically synthesized salt and salt made from seawater. Chemical salt is manufactured using sodium chloride (NaCl) as a raw material, while salt made from seawater can be represented by solar salt. The present invention is applied to solar salt. Currently, most of the salt referred to as solar salt is harvested from salt fields, and the primary process involves the brine extraction process, which draws seawater (brine) into the salt fields. At this time, in order to maintain the salinity of the seawater, gates are provided in the waterways or pipes, and valves are provided in the gates so that the appropriate salinity can be controlled. After that, the second process is an evaporation process in which the brine drawn in during the first process is naturally evaporated using the sun (sunlight) and wind on a large area of the salt field (also called a salt pan) to evaporate only the water from the brine. During this evaporation process, as water evaporates, the salt concentration increases, and typically, the salt concentration becomes 23 to 25 degrees. As water is lost through this evaporation, the salt concentration increases and a crystallization process occurs. However, after collecting the brine, the evaporation process requires evaporating the water for about a week in the first stage, resulting in a saltwater with a salinity of only 6 to 8 degrees. Therefore, in order to reach a salinity of 23 to 25 degrees for the crystallization process, a second or third evaporation process is usually required. This evaporation process is carried out multiple times as needed, and when the concentration of the brine reaches a certain level during this process, salt crystals are formed in the third stage (also known as salt flowers blooming), which is a salt crystallization process. At this time, the crystallized salt crystals sink to the bottom of the salt field. At this time, as the salinity reaches about 27 degrees, salt flowers bloom, and salt crystals begin to form little by little on the bottom of the salt field. After that, the fourth step is the harvesting process, in which salt crystals are scraped out with a scraper once they have sufficiently formed. Afterwards, the salt harvested by scraping with a scraper can have impurities attached, such as fine dust particles blown in by the wind used in the moisture evaporation process of the second process, removed through a washing process in the fifth process. After that, the sixth step is a drying process in which the sun-dried salt obtained by washing is dried in the sun to remove moisture adhering to the surface of the salt during washing. In this way, the salt (solar salt) obtained through the drying process is manufactured in the 7th process by packaging and storing. However, if it snows or rains during the first process of collecting brine, the collected brine is sent to a brine warehouse for temporary storage. At this time, when the salt concentration reaches 23 to 25 degrees during storage in the brine warehouse, it is sent to a crystallization pond for the third process, salt crystallization, so that the salt can be separated. In this way, when salt flowers bloom during the salt crystallization process, it takes about 1 to 4 days to harvest the salt. At this time, for harvesting, most workers gather the salt together with a scraper, store it temporarily to remove some moisture, and then transport it to a salt warehouse. Afterward, the brine is drained from the salt in the salt warehouse and the finished salt is packaged to become solar salt. The most difficult part for the worker at this stage is collecting the crystallized salt with a scraper and transporting the collected salt to the salt warehouse. For reference, current standards for solar salt stipulate insoluble matter of 0.15%, sand content of 0.2%, arsenic of 0.5%, and lead of 2.0% or less, but there are currently no inspection standards for bacteria or E. coli levels.
