Main source of salt is rocks and sea. Maximum consumption of salt is in its natural form after being produced from sea or directly from rock. But with time, awareness on uses of salt
have grown manifold and the demand of refined iodised salt is increasing tremendously during the last few years.
not only helps in increasing purity of salt but also improves flow-ability and use of anti-caking agents helps in keeping quality too. During refining and drying process iodisation is done which is important for human body to avoid various diseases.
Refined salt is further graded for various applications like kitchen salt, table salt and industrial salt.
SSP has developed two basic process for refining of salt:
1) Mechanical Salt Refinery
2) Vacuum Crystallisation
