The given ingredient system calculates the speed of each quantitative rotor pump motor or motor based on the ratio of each material, detects the weight of the material through a weighing module, calculates the actual material flow rate based on the speed signal and weight signal, and uses PID The output of the adjustment controls the frequency converter to change the speed of the disc motor or the quantitative rotor pump motor, in order to control the material flow rate to reach the given value. When 90% of the pre composed materials are reached, the system automatically switches to slow feeding until the pre-set parameter values of the materials are accurately reached. The feeding system follows this process, and when the post feeding is also completed, the weighing instrument displays the total weight value of. During this process, the weight value of each material is also displayed separately. Then, the system automatically opens the discharge door and synchronously starts the conveyor at the bottom of the batching to transport the materials to the next unit or for batching.

The Batching system adopts rotor pump feeding and automatic metering control. A weighing module is installed under the material tank to monitor the weight of the ingredients. When the materials added to the material tank meet the formula requirements, the feeding should be automatically stopped and the conveyor should be automatically closed. A closed-loop Weighing system is formed through a computer and a frequency converter. The computer compares the size of the weighing instrument with the given flow signal, controls the frequency of the frequency converter to control the speed of the conveying pump, and controls the flow rate, so as to control the proportion of ingredients entering the mixing tank. A temperature transmitter is installed in the mixing tank, and the cooling water pump pumps water to cool it. The flow rate of the water is controlled by a frequency converter, and a closed-loop temperature regulation system is formed through a computer to control the outlet temperature of the material. Temperature transmitters and preheating steam electric valves are installed in the material tank, and their respective temperature closed-loop control systems are constructed through computers to control the temperature of the materials. To monitor the pressure and temperature here, the speed of the delivery pump is controlled by their respective frequency converters. Each material tank is equipped with a stirring pump, and both the stirring pump and the conveying pump are connected to the power supply through thermal relays, contactors, and air switches to protect and control the motor. The suction and release of the contactor are controlled by a computer.
