Abstract: Aiming at the problems of long drying time, low manual slicing efficiency, and heavy workload in Xinjiang area, a pepper slicer was designed. The key structure and working parameters of the pepper slicer was determined through theoretical analysis and parameter calculation. Through the performance test, the speed and the height of cutting disc and the linear speed of conveyor belt were selected as independent variables. The structural integrity of slices of chilli was used as the test index. The secondary rotation orthogonal combination test was carried out. A regression model of test index and influencing factors was established. The model showed that the optimal operating parameters of the pepper slicer were as follows: cutting disc speed 118 r/min, conveyor belt linear speed 0.5 m/s, cutting disc height 10 mm. Through experimental verification, under the optimal parameter combination, the slice integrity was 97.85%, which was basically consistent with the model prediction result. Compared with manual slicing, the efficiency is improved by 344%, which meets the requirements of pepper slicing operations in Xinjiang. This research can provide reference for the design of pepper slicer.
