This paper presents the design and automatic control methods employed to implement a open-close mechanism for a food compression processor. The automatic open-close mechanism is intended as a robust approach in compressing incoming food that posses a wide range of physical properties. The method is based on the estimation of compression pressure through current measurement. Test results show that the proposed mechanism effectively controls the compression pressure of the processed food which results in enhanced overall system robustness.
