Abstract:
A salt making method comprising putting a crude salt-water mixture (5) comprising crude salt or rock salt and bittern in a vessel (1), blowing the air from a pipe (7) into the mixture (5) with a pump (9), crystallizing the component salt out of the mixture (5), and precipitating the salt as a common salt (S) at the bottom of the vessel (1). The remainder of the mixture (5) is discharged through a filter (13) into a tank (17), where it is stored as a concentrated brine (15), which is then discharged through a filter layer (16) and a drain (18), and crude salt is dissolved therein to recycle as a crude salt-water mixture. The concentrated brine (15) may be used after being mixed with the extracts of aloe, mozuku (Nemacystis decipiens), rice bran, etc. The air may be blown into the mixture (5) under heating.
