Are You Using Proper Moisture Control?

The optimum moisture content for treated sodium chloride salt is less than 4%. Moisture levels in salt during processing are critical as the material can quickly have too little or too much, instantly affecting the outcome.

Multiple salt mining methods are used and MoistTech is able to assist with proper moisture measurement no matter how the salt is mined.

SOLAR EVAPORATION: its use is practical only in warm climates where the evaporation rate exceeds the precipitation rate, either annually or for extended periods, and ideally, where there are steady prevailing winds. 

UNDERGROUND MINING: this is probably the most dramatic method of gathering salt. While mine temperature varies with depth, the average temperature remains about 70°F year round.

VACUUM EVAPORATION: evaporation of salt brine by steam heat in large commercial evaporators, called vacuum pans. This method yields a very high purity salt, fine in texture, and principally used in those applications requiring the highest quality salt.

MoistTech’s IR-3000 salt moisture sensor utilizes the principle of near-infrared reflection (NIR) to provide the most accurate and repeatable results. Connected directly to your PLC, the moisture measurements can be instantly displayed to allow for adjustments anywhere in the process to eliminate waste.
