The Control system takes the electronic scale (with the composition of TEDEA model 616S high-accuracy transducer and Mettler PANTHER instrument) as the foundation, with S7-300 PLC from Siemens as core of the control, and equipped with Industrial Personal Computer made by Taiwan Advantech Co., Ltd, realizes the recipe management, production data management, running status management, and the realization of the production instructions by commands of human-machine conversation. The system is connected into one organic whole by the network communication combining with the peripheral operation equipment, to realize the full process automatic control and management of dosing, feeding and mixing from the outlet of the silo to the outlet of mixer, then to meet the requirements of additives for dry mix products.
