Vacuum salt

Vacuum salt is produced by its evaporation from natural brines - waters of underground springs, estuaries, lakes or artificially flooded mines. Such method of extraction is known as a vacuum method. By adding pure unsalted water to salt masses through the system of special boreholes under the ground, they receive salt brine that then comes up to the surface for cleaning. Then it is sent to special vacuum chambers where the liquid begins to evaporate under the low air pressure resulting in and salt crystals’ forming. After that, by means of special devices, the salt is separated from water and sent for further treatment. At the end of this process, we receive fine and convenient for cooking PDV Salt - snow-white color, fine homogeneous structure and exclusive purity of sodium chloride (NaCl) - up to 99.5%.

Rock salt

A substance of natural origin, its main deposits are concentrated in places where seas and oceans used to be located in ancient times. They rock salt is extracted by mining and quarry methods. Salt deposits can be located at a depth of 100 to 600 meters that is why for salt extraction the deep mines and tunnels are made. The extraction is made by means of special devices; all the large pieces of salt are crushed and then are lifted upwards by trolleys or elevators. The content of sodium chloride in the rock salt is quite high (98-99%) almost without any moisture.

Solar salt

It is produced by evaporation of seawater or waters of a salt lake in special pools. The content of sodium chloride is less than in other types, - 94-98%.Moreover, solar salt contains much more different ions, so it can differ in taste.

Deposited salt

This type of salt is extracted from salt lake floors - it naturally settles on the floor in the process of crystallization. After the extraction, it is washed in loisomers/pyramids which are specialized installations stacked on shores of salt lakes or saline basins. Then the salt crystals are converted into food-grade salt.
