Abstract

In response to the lack of machines for cutting dried chili peppers into segments and the problems of low efficiency and high damage rate of existing segmenting machines, a rotary knife-style dried chili pepper segmenting machine was designed. The working mechanism of the rotary knife in coordination with the drum for cutting was explained, and structural parameters were determined based on the motion characteristics of the rotary knife and practical requirements. Three factors affecting chili pepper segmenting efficiency were identified, and the chili pepper segmenting qualification rate and damage rate were used as experimental indicators. Experiments and data processing were conducted using software, a regression model between the experimental indicators and influencing factors was established, and the optimal parameter combination was determined. The experimental results showed that when the rotary knife speed was 51 r/min, the conveyor belt speed was 0.6 m/s, and the drum speed was 51 r/min, the device damage rate was 1.42%, and the cleaning rate was 98.21%, meeting industry standards. This study can provide a reference for the research of rotary knife-style dried chili pepper segmenting machine technology and equipment.

针对干辣椒切段机械匮乏且现存切段机工作效率低、破损率高等问题，设计了一种滚刀式干辣椒切段机，阐述滚刀与滚筒配合切割的工作机理，根据滚刀的运动特点和实际需要得出结构参数。确定了影响辣椒切段效率的三个因素，以辣椒切段合格率和破损率作为试验指标，通过软件进行试验设计及数据处理，建立了试验指标与影响因素之间的回归模型，并确定最优参数组合。试验结果表明，当滚刀转速为51r/min，传送带速度为0.6m/s，滚筒的转速为51r/min时，装置损伤率为1.42％，脱净率为98.21％，符合行业标准。该研究可为滚刀式干辣椒切段机技术与装备研究提供参考。
