In order to improve the automatic filling level of multi particle oil capsicum materials, a new generation of oil capsicum filling machine control system is developed by using PLC control technology in combination with the physical characteristics of oil capsicum materials and the filling process requirements of the enterprise. The control system is debugged and filled with 210, 220 and 280 g bottles of Laoganda oil capsicum series products. The results showed that the qualified rate of the control system was 100%, the filling speed was about 411 bottles/hour, and the average solid content of each bottle was about 63.6%. It can realize the high-speed and accurate automatic filling of multi particle oil and pepper materials, meet the production demand of the enterprise.
