| 摘 要： | 为了获得榨菜缩短茎的最佳切割要素组合,在TMS-Pro质构仪上开展榨菜缩短茎切割的单因素试验和正交试验,以最大切割力和平均切割力为试验指标,探究刀刃类型、滑切角度、切割速度、切割方式对榨菜缩短茎切割过程中切割力的影响。结果表明:滑切角度对最大切割力和平均切割力影响显著(P<0.05),刀刃类型对平均切割力影响显著(P<0.05),锯齿刃比光刃省力。为有效降低最大切割力和平均切割力,榨菜缩短茎切割的参数宜确定为锯齿刃,滑切角度20°,切割速度80 mm·min-1。此时,最大切割力为86.2 N,平均切割力为53.1 N。研究结果可为榨菜收获机的切割装置设计提供理论依据。

| Abstract: | In order to obtain best parameters for the cutting of shorten stems of mustard tuber, the single-factor experiments and orthogonal tests were carried out on the TMS-Pro texture analyzer. The maximum cutting force and the average cutting force were selected as test indexes, and the effects of cutter type, sliding angle, cutting speed and cutting direction on the cutting force during the cutting process of shorten stems of mustard tuber were analyzed.It was shown that the sliding angle had significant (P<0.05) effect on the maximum cutting force and the average cutting force. The cutter type had significant (P<0.05) influence on the average cutting force, and the sawtooth cutter was more labor-saving than the light cutter. The most labor-saving combination for cutting of shorten stems of mustard tuber was as follows: sawtooth cutter, sliding angle of 20°, and cutting speed of 80 mm·min-1. Under this circumstance, the maximum cutting force was 86.2 N,and the average cutting force was 53.1 N. These findings could provide references for the design of the cutting device for shorten stems of mustard tuber. |
