The dosing system is composed of a touch screen as the HMI, a weighing meter, a temperature control meter, as well as a water filling control and a starch delivery control device. The system is also equipped with a number of pumps, shut-off valves, liquid level and material level sensors. Through the screen to monitor the deviation of the dosing process, and automatically according to the proportion of the formula to correct the back of the dosing ratio, in order to ensure the accuracy of the formula; can be realized with the user's production management system of data communication, through the parameter setting, automatically according to the production of orders to be produced to determine the control amount of the program can be automatically modify the formula can be to meet the dosage production line of the technological requirements. The batching system adopts touch screen as the human-machine interface, weighing instrument, temperature control instrument, water filling control and starch conveying control device. The system is also equipped with a number of pumps, shut-off valves, liquid level and material level sensors. Through the screen to monitor the deviation of the dosing process, and automatically according to the proportion of the formula to correct the proportion of the dosing of the back to ensure the accuracy of the formula; can be realized with the user's production management system of data communication, through the parameter setting, automatically according to the production of the order to be produced to determine the amount of control, the program can be automatically modify the formula can be to meet the dosage production line of the technological requirements. Feeding system is suitable for the site without continuous dosage requirements, can be batch dosage, batch allows the existence of a certain time interval, kettle weighing before and after the feeding of the two batch time interval of 3 ~ 5min, each batch of material from a variety of materials, materials accounted for the ratio of the requirements of the process over a period of time in a relatively fixed proportion of the composition of a single material requirements are not stringent, as long as the proportion of the composition of the material in the more batches to meet the process requirements. Requirements can be. Automatic feeding system due to material measurement, transportation, adding and other aspects of the time can be overlapped, in the control process can be used in parallel, in order to save feeding time, improve feeding speed. Various materials are stored in different silos, silo feeding is generally used in the form of electric vibration feeding, screw feeding or gate feeding. Measuring silo and equipped with pressure or weighing module for force and power conversion, the signal is amplified by the secondary instrumentation processing access to PLC or DCS to complete the measurement. In some applications with wide time requirements, a measuring trolley can be used for uniform measurement, measuring trolley running along the track, positioned in turn to the bin under the proportional material dosage, the dosage of various materials using the subtraction method of calculation. There is also a single fixed measuring bin way, the bins in a ring-like distribution around a measuring bin, the measurement of the material also uses the subtraction method, the material from the chute or conveyor in order to proportionally add to the measuring bin. The materials after dosing and metering are assembled, generally forming a layer or segment distribution, and then conveyed to the receiving port by the conveying equipment (such as screws or trolleys) to enter the next process, i.e., completing a batch of material dosing.
