Salt processing, particularly for evaporated salt, involves a method where salt is extracted from underground deposits and converted into usable crystals. Here's a breakdown:
Evaporated Salt Production Process
The evaporated salt production method, described in our reference, is the most common form of salt processing used today. It involves three key stages.
-
Brine Creation:
- Freshwater is injected into an underground salt deposit.
- The water dissolves the salt, creating a saturated brine solution.
-
Brine Extraction:
- The brine solution is pumped back up to the surface.
-
Evaporation & Crystallization:
- The brine is boiled in large evaporators.
- As the water evaporates, salt crystals form.
- These crystals are then collected and processed further depending on the desired form.
Different Salt Processing Methods
While the above is the standard for evaporated salt, other methods exist:
- Solar Evaporation: Uses sun and wind to evaporate seawater in shallow ponds.
- Rock Salt Mining: Mining from underground salt deposits.
Benefits of Evaporated Salt Processing
The process used for creating evaporated salt allows for:
- Purity: The resulting salt is often very pure due to the controlled process.
- Consistency: This allows manufacturers to easily produce salt crystals of a uniform size.
In Summary
Salt processing for evaporated salt involves extracting brine from underground deposits, then evaporating it to form salt crystals. This method creates a consistent and pure product, widely used in cooking and other applications.
