This invention relates to the field of sodium nitrate processing equipment technology, and discloses a sodium nitrate preparation equipment and preparation method, including a tank, four support frames fixedly connected to the outer wall of the tank, and a feed pipe connected through the top of the tank. This invention addresses the problem of some crystals solidifying on the inner wall of the tank due to high temperature. It incorporates a limiting mechanism and a floating mechanism inside the equipment. When the motor drives the stirring frame to agitate via a drive rod, the vortex-like solution generates rotational force.
