The difference between sea salt and table salt can be distinguished from the size aspect, nutritional aspect and color aspect.

1, size-wise: sea salt is coarser and has more particles than table salt because it is not processed as much. Sea salt is evaporated seawater refined. Table salt is generally mined from underground salt mines, in the processing into finer crystals.

2. Nutritionally: Some sea salts are not as heavily processed as refined table salt, so they retain more trace elements. Generally we processed salt is also added additives so that it is not easy to solidify the lump, so the trace elements to lack some.

3, color: according to the origin and the different minerals contained in the sea salt color, there are white, pink, black, gray and mixed colors. While ordinary refined salt is usually made into white fine particles.

The process of making salt

1, natron

It is actually the process of extracting raw materials for the production of 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

is the growth of salt, the use of artificial or mechanical salt will be put away in piles.
