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.
