杏核挤压式开口的试验研究

The Experimental Study of Apricot Nuclear Openings in Extrusion

通过试验分析杏核的物料学特性，确定杏核开口的影响因子，为机械的设计提供理论依据，并为参数的优化提供方向。应用正交试验，测定杏核挤压速度、挤压位置以及尺寸大小对杏核开口的影响；应用单因素试验测定含水率对杏核开口的影响。通过正交试验，确定杏核开口最佳水平是万能试验机挤压进程为25~30 mm/min，挤压位置为杏核Y轴即缝合线位置，长轴尺寸大小为16.7~18.5 mm；通过单因素试验，确定杏核含水率为5.8%时，杏核开口效果最好。在理论分析上，可以通过正交试验、单因素试验得出的物理水平值为优化参数，制造杏核开口机械，实现杏核开口的机械化。

Through the experimental analysis of apricot nuclear physics factors, we can ascertain the influence factors of apricot pit opening, provide theoretical basis for mechanical manufacturing, and provide direction for the parameter optimization. The orthogonal test can measure the effects of extrusion speed, extrusion position and size of apricot pit to apricot pit openings, application of single factor experiment measures the effects of moisture content of apricot pit openings. Through orthogonal test, we can find out the best level for apricot pit openings： universal testing machine extrusion process for 25~30 mm/min. The extrusion position of apricot pit Y, namely suture location. The size of long axis is 16.7~18.5 cm, single factor experiment shows that apricot pit openings works best when the moisture content of apricot pit is 5.8%. On the theoretical analysis, the orthogonal experiment shows that the single factor experiment can get a better physical level to optimize the parameters for apricot pit opening. This research of physical parameters can lay a theoretical basis for realizing manufacturing apricot pit openings machinery and the automation of apricot pit machinery openings.
