薄皮核桃机械分级与破壳特征提取研究

Study on feature extraction of shell breaking and machine grading of thin shell walnut

为提取不同品种薄皮核桃的机械分级与破壳共性特征,扩展薄皮核桃分级与破壳取仁工艺适应性,以产于新疆和云南的4种薄皮核桃为研究对象,通过基础参数测量和力学压缩特性试验研究薄皮核桃的尺寸、质量和压缩力学特性的差异和共性规律。结果表明:不同品种样品核桃的结构特性和压缩力学特性呈现的变化规律相似,基于试验参数内任意种核桃设计的机械破壳设备,对薄皮核桃分级与破壳均具有较好的适应性。为不同品种的薄皮核桃筛选分级、破壳取仁工艺和相关破壳机械设计提供了参考依据。

In order to extract the common features about machine grading and shell breaking of different walnut,and extend the adaptability of thin skinned walnut for classification and shell breaking,for kinds of walnuts were chosen as the research objects,including 185 walnut of Xinjiang（W185）,xixiang walnut of Baoshan Yunnan（XX）,Yangbipao walnut of Dali（YBP）,Dayao three Tai walnut of Chuxiong（DYST）.Studied the differences and commonness of size,mass and compressive mechanical properties of thin walnut by basic parameter measurement and mechanical compression test.Using Excel software and Origin software to deal with the test data,the results of the study showed that：The change rule of structural characteristics and compressive mechanical properties of different walnut varieties were similar;The mechanical crushing equipment based on any kind of walnut design in the test parameters had good adaptability to the classification and crushing of the walnut walnut.The test results can provide references for different varieties of thinskinned walnut screening and shell breaking extraction process and related crust mechanical design.
