How is salt processed?
There are three methods used to produce salt, solar, evaporation and rock mining. Vacuum Evaporation Method Salt from any of several sources is dissolved to create saturated brine. This brine is then pumped into vacuum pans. The steam vessels are normally in a series of three. The brine is pumped into the pans, steam is then introduced. When the brine reaches the boiling point the brine separates into steam and the salt begins to crystallize. The heavier salt crystals will fall to the bottom of the pan in a slurry. The salt slurry will then be drawn off and sent to the dryer wheel. For additional information, visit http://www.saltinstitute.org/Production-industry. Solar Evaporation Method The oldest method of salt production known to man is solar evaporation. Solar salt production is the capturing of sea water in shallow ponds where the sun evaporates most of the water. This method uses two types of ponds — concentrating ponds and crystallizing ponds. In the concentrating ponds the wa
