The process of making table salt is as follows:

Acquisition of raw materials for table salt, with seawater as the main raw material, or extraction of table salt from deposits and common salt mines. Preliminary treatment, the raw materials will be collected, cleaning, sieving, mixing and other operations, so that the raw materials to meet the subsequent needs of the state. Melting, the raw materials are melted to form a molten pool in which the elements are mixed to form table salt of various compositions. Dewatering, refining, making purer and removing impurities, toxic substances, etc.

1. Raw material procurement

First of all, let's take a look at raw material procurement. The raw materials for making salt are mainly seawater and salt fields. The quality of seawater has a crucial impact on the quality of salt. Therefore, salt-making factories usually choose sea waters with clear water and high salt content as the source of raw materials.

To ensure the quality of seawater, salt plants usually send professionals to sample and test the seawater, mainly for salt content, microorganisms, heavy metals and other indicators. Seawater that meets the requirements will be introduced into the salt fields, where it will be gradually turned into salt through sun exposure and natural evaporation.

2. Salt-making process

Next is the salt-making process. The salt-making process mainly includes two parts: solarization and processing. Sunshine salt is a natural process carried out in the salt field, through the sun exposure, seawater gradually evaporated, leaving behind is the crystalline salt. Processing is the purification and fine processing of the crude salt obtained, so that it reaches food-grade standards.

Salt plants usually use a series of physical and chemical methods to purify the crude salt, such as washing, precipitation and filtration. After purification, the salt also needs to go through fine processing, such as grinding and drying, etc., to finally get a good quality salt product.

3. Product inspection

Finally, product inspection. In order to ensure the quality and safety of the salt products, the salt factory will carry out strict inspection on each batch of products. The inspection includes the composition, purity, particle size and water content of the salt. Only products that meet the standards will be allowed to enter the market for sale. In addition, in order to meet the needs of different consumers, salt-making factories also produce different sizes and types of salt, such as fine salt, coarse salt and iodized salt.

All in all, the production of salt is a complex process, which needs to go through many links such as raw material procurement, salt production process and product inspection. Through the strict control of these links, we can ensure the quality and safety of salt products and meet the needs of consumers.
