Current salt production is mainly manual, labor-intensive, but productivity is not high.
The salt making process is long and greatly affected by the weather, so it can even result
in total loss. Faculty of Engineering - Vietnam National university of Agriculture has
calculated, designed, and manufactured a model of sea salt production equipment using
new technology, including a system of equipment to produce tap water from seawater
and a fractional crystallization system. from water. This new model of sea salt production
equipment with new technology has a productivity two to three times higher than the
traditional method while also reducing the floor area many times while improving the
quality of salt and creating Many products at different levels serve human consumption
in food and industry.
