Description

[0002] The crystallization kettle is a mixing reaction equipment used in the process of mixing and stirring materials in the chemical, pharmaceutical, food and other industries. In the prior art, most traditional crystallization kettles use a stirring mechanism to stir the inside of the kettle, and a cooling mechanism is connected to the outside of the kettle body for crystallization. However, there is a certain distance between the lower end of the stirring rod in the stirring mechanism and the bottom of the kettle, resulting in some raw materials not being stirred with it, and then the crystallization speed of the raw materials at the bottom of the reactor is slowed down. In addition, the horizontal stirring rod can only stir the raw materials at the corresponding position, while the stirring effect on the lower layer of raw materials is poor, which affects the crystallization effect and the discharge speed.
