How is salt produced? The process of salt production

Nachao is actually the raw material extraction process for the production of raw salt. Seawater is the raw material for salt production, in order to ensure the normal production, we must do everything possible to ensure the supply of raw materials; brine production is to gradually increase the concentration of brine, and finally concentrated into saturated brine; when the concentration of salts reached saturation, crystallization will be precipitated in the form of crystals; salt collection is the salt will be grown into the use of artificial or mechanical salt collection of salt dislike stacks.

Iodized salt will be decomposed into a single iodine and evaporate at high temperatures, so don't use salt to "explode the pan" when frying, should wait for the dish to be eight mature before putting in the salt, so as to minimize the loss of iodine. Ordinary market salt is no shelf life, but added iodine, zinc, selenium, calcium, riboflavin and other trace elements of edible salt shelf life of one year.
