Previously, salt was produced with canvas lined on the field. It is known as labor consumption,  and less effective production.

The new method from NEC improved canals system, changed purifier’s location, and used pipe plastic system to lead condensed salt to the drying area with a very detailed calculation in the production line.

This design helps reduce 45-50% labor consumption compared to the current method, instead of using wheelbarrow or shouldering. In addition, it also helps increase salt productivity from 25-30%, higher quality, and very few impurities compared to previous methods.
