Sea salt is evaporated using a natural process involving sun and wind.
The Evaporation Process
The primary method for evaporating sea salt relies on a few key elements:
Solar Evaporation
-
Brine Introduction: First, seawater, also known as brine, is guided into large, shallow ponds or salt pans. These are often constructed in areas with high sun exposure.
-
Sun's Role: The heat from the sun is crucial. It provides the energy needed to turn the water in the brine into vapor, which then rises into the atmosphere.
-
Wind Assistance: Wind plays an important role too, as it accelerates the evaporation process by removing the water vapor from the surface of the brine, allowing the process to continue more quickly.
Natural Process
According to the references, once the brine is in the salt pans, "the sun's heat and wind start the natural evaporation process." This natural process leaves behind concentrated salt crystals once the water has evaporated.
Harvesting the Salt
Once the water has completely evaporated, a thick crust of salt remains. This salt is then harvested and processed for various uses.
Summary
In short, sea salt evaporation is a natural process driven by solar heat and wind, which gradually removes water from brine until only salt crystals remain.
