[0002] Enamel reactor is a kind of intermittent reaction device commonly used in the production process of chemical and pharmaceutical intermediates. Its stirring forms include anchor stirring, frame stirring and paddle stirring. Different stirring methods are used for different reactions. For example, anchor stirring is often used in crystallization, frame stirring or paddle stirring is often used in heterogeneous reaction systems, and paddle stirring can only be used when the viscosity of the reaction liquid is relatively high.
