A method of harvesting bay salt through several precipitating, evaporating and storing procedures is provided to obtain high quality bay salt with low salinity and high content of mineral. A method of harvesting bay salt comprises the steps of: precipitating sea water pollutants in a first step; pumping the precipitated sea water to a first evaporating pond with passing through a 12-stage evaporating pond along No. 1-5 sea water tank and storing sea water with a salinity of 12% in a No.5 sea water tank to precipitate an insoluble fraction in the second step; pumping the sea water in the No.5 to No.4,3,2,1 sea water tank with passing through a 12-stage evaporating pond and storing sea water with a salinity of 22 to 25% in a No.6,7,8,9 sea water tank; washing a crystallizing pond with water; conveying concentrated brine in the No. 6,7,8,9 sea water tank to the crystallizing pond; and harvesting bay salt crystallized by solar heat or a wind for 9hr from 7 a.m. to 4 p.m. |
