Method for tedding edible salt in natural seawater greenhouse

The invention provides a method for tedding edible salt in a natural seawater greenhouse. The method takes natural seawater as a raw material and comprises the following steps in a glass greenhouse: 1) naturally precipitating, and separating solid suspended matter impurities; 2) filtering and purifying; 3) precipitating again; 4) automatically flowing from a buffer pool to irrigate a crystallizing pool; 5) crystallizing; 6) carrying out salt collection and controlled spraying; and 7) screening and packaging. According to the invention, the south wall and the side walls of the greenhouse shed are made of glass, the south glass wall is obliquely arranged, ventilation holes are formed in the left glass wall and the right glass wall, a chimney of a hyperbolic structure is installed at the rear end of the greenhouse shed top, a fan is installed at the position, with the smallest inner diameter, of the chimney and connected with a power generator through a straight rod, a cooler is arranged on the top of thechimney
