摘　　要：木薯去皮是许多木薯产品加工的首要工序,人工去皮成本高、效率低,难以满足生产要求,为此,设计了一款在上料机辅助下可连续作业的木薯去皮机。为优化作业参数,以木薯长度、木薯直径、去皮机螺旋轴旋转速度作为影响木薯去皮效果的因素,以去皮合格率、断薯率、减重率为评价指标,采用正交试验方法进行试验。结果表明,对木薯连续式去皮机去皮合格率影响程度从大到小依次为螺旋轴转速、木薯长度、木薯直径;对断薯率影响程度从大到小依次为木薯长度、木薯直径、螺旋轴转速;对减重率影响程度从大到小依次为木薯直径、螺旋轴转速、木薯长度。优化后最佳作业参数为螺旋轴转速10 r/min、木薯长度10 cm,木薯直径大于60 mm。Cassava peeling is the most important process of many cassava products.It is difficult to meet the production requirement because of its high cost and low efficiency.Therefore,a kind of peeling machine is designed,which can work continuously with the assistance of feeding machine.In order to optimize the parameters,the cassava length,diameter and the rotation speed of the screw axis were taken as the factors affecting the peeling effect,the acceptance rate,the broken rate and the weight loss rate of cassava were taken as the evaluation indexes.The orthogonal test method was used to carry out this experiment.The results showed that the degree of influence on the acceptance rate was screw axis rotation speed,cassava length and diameter from big to small;The influence degree of the broken rate from big to small is cassava length,diameter,axis rotation speed;and the influence degree of the weight loss rate from big to small is cassava diameter,axis rotation speed,cassava length.After optimization,the optimum operation parameters were 10 r/min of screw axis rotation speeds,10 cm of cassava length and over 60 mm of cassava diameter.
