Shouguang salt production originated in the Shang and Zhou dynasties. According to the "Book of Shang Yu Gong", this area "has a wide seashore, its fields are full of brine, and its tribute salt is scarce"; in the Shang and Zhou dynasties, people used pottery jars to boil the sea brine, which was called "boiling the sea for salt"; in the Han Dynasty, boiling salt was changed to frying salt; in the Ming Dynasty, frying salt was changed to boiling salt; in the early Qing Dynasty, salt was dried in the beach fields until now. The salt-making tools are different in ancient and modern times, but the processes of beach repair, water supply, brine production, crystallization, and salt collection are basically the same. Beach repair: evaporation ponds and regulating ponds are pressed 1 to 2 times, and crystallization areas are pressed 3 times to make the soil reach the optimal water content and density, so that the bottom of the pool is solid and flat without leakage. Water supply: the method of extracting underground brine. The distance between wells is not less than 150 meters, the depth of the large well is 68 meters, and the depth of the machine well is 6080 meters. When making a well, the freshwater layer is first sealed with red mud, and the outside of the saltwater layer well pipe is filled with sand to make the well water high in concentration and large in volume. After the well water is extracted, it enters the water storage circle for standby. Making brine: Making brine is the process of using natural conditions to gradually concentrate well water into saturated brine. Crystallization: Crystallization is the main process of salt making. In ancient times, boiling, frying and boiling were used, and in modern times, it is mainly beach drying. Collecting salt: Use salt rakes to pile up the salt, and then transport the salt into and out of the pile.
