How edible salt is made: natatorium, brine making, crystallization and salt collection.

1, natatorium

Actually, it is the raw material extraction process for producing raw salt. Seawater is the raw material for salt production, in order to ensure the normal production, must do everything possible to ensure the supply of raw materials. At present, there are two types of tide, one is the natural tide, and the other is the power tide. Natural tidal wave is to let seawater flow naturally along the tidal ditch at high tide; power tidal wave is generally used axial flow pumps to introduce seawater, which is characterized by the natural conditions are not restricted.

2, making brine

Making brine is carried out in a wide area of the evaporation pond, according to the daily evaporation of appropriate control of the depth of the evaporation pond to go, so that the concentration of brine gradually increased, and finally concentrated into saturated brine.

3, crystallization

Sea water in the continuous evaporation and concentration process, the concentration of various salts continues to increase, when the concentration of salts to saturation, will be precipitated in the form of crystals, in the supersaturated solution, and constantly maintain the degree of supersaturation, the crystals will be able to continue to grow.

4, salt collection

It is the growth of salt, the use of artificial or mechanical salt will be collected in piles.

How to choose edible salt:

1, quality grade: reference to China's "National Standard for Edible Salt", *** divided into superior, first class, second class, try to choose superior and first class edible salt when buying.

2, additives: although the additives of edible salt are within the scope of the national standard, but when purchasing it is recommended to choose salt with fewer additives.

3, choose salt with anti-counterfeiting labels: anti-counterfeiting labeling should be clear, there is a complete list of ingredients, and manufacturers of sub-assembling enterprises have specific plant address, telephone and other specific information.

4, look at the packaging: pattern text are clear, and the production date is clear, with a hand picking does not fall.

5, look at the texture: qualified salt white color, uniform particles, no powdery substances.
