The Batching system is a multi-process, multi-link multi-task combination system, which controls the raw material dissolution, filtration, homogenization and sterilization process in the entire production process according to the set process requirements, automatically adjusts the key parameters such as material level, temperature and pressure accurately, and continuously and stably outputs the product. The whole liquid handling and conveying process is monitored by PLC combined with fieldbus, and the system fault is recorded, displayed and alarm output. The automatic control process involves a number of control loops, including the raw material ratio control loop, the temperature control loop in the reaction process and the finished product measurement and packaging control loop. The project uses steam heated reactor to complete the reaction of the process. The process of adding raw materials is as follows: first the liquid reaction material is added to the reactor, and then the medium temperature is heated to slightly higher than the reaction temperature or the melting point of the solid reactant; In the case of constant stirring, slowly add solid reactants, so that it continues to react or dissolve, to avoid precipitation. Due to different formulations, each product needs about 4 kinds of liquid raw materials and about 2 kinds of solid raw materials, and the ratio of ingredients is required to reach 0.1%.

The reactor is provided with a feed pipe, and the feed pipe is provided with a feed valve; The stirring assembly is arranged in the reactor body, and the stirring assembly is used to stir the material; The heat exchange component comprises a heat exchange tube and a medium box, the heat exchange tube is arranged inside the reactor body, the heat exchange tube is provided with a liquid inlet pipe and a liquid outlet pipe, the liquid inlet pipe and the liquid outlet pipe are extended out of the reactor body, the medium box is arranged on one side of the reactor body, the medium box is provided with a first pipe and a second pipe, the first pipe and the second pipe are connected with the liquid inlet pipe and the liquid outlet pipe respectively; The control component comprises a temperature sensor, a weighing sensor and a controller. The temperature sensor is arranged in the reactor body, the temperature sensor is electrically connected with the heat transfer component, the weighing module is arranged at the bottom of the reactor body, the weighing module is electrically connected with the feed valve, and the controller is electrically connected with the feed valve, the heat transfer component, the temperature sensor and the weighing sensor.
