In the Refined Salt production method, after the raw salt washing process, the condensate taken from the process is melted with water and the stone, sand, rope, paper, plastic etc. in the solution. It is passed through special decanters and filters to separate foreign substances and sludge layer. After the filter process, the saturated sodium chloride solution is fed into the Refined Salt unit, and the solution, which starts to evaporate with the evaporation system operating under vacuum, turns into salt crystals and forms the refined salt. It has a round structure and is fluid.
