Abstract

Abstract: 【Objective】 In order to fully understand the physical and aerodynamic characteristics of almond shell and kernel material and lay a foundation for the research and development of almond shell and kernel separation device. 【Methods】 through the material characteristics comparison test of two representative Almond Varieties (Shache No. 3 and Shache No. 18), the shell shape, friction angle, material composition and density of these two almonds were studied and analyzed The differences and characteristics of the suspension speed and the degree of the suspension are also discussed. 【Results】 The results showed that there was little difference between the two in terms of shell kernel material size and material composition, and the obtained data were relatively close, while the friction angle and density of Shache No.18 were slightly higher than those of Shache No.3. In addition, the average suspension velocity of Shache No.18 was 10.42, 9.11, 8.54 and 13.88 m/s, respectively. The average suspension velocity of Shache No.3 was 10.03, 8.82, 8.15 and 13.50 m/s respectively. The data showed that the suspension velocity of Shache No.18 was higher than that of Shache No.3. 【Conclusion】 There are differences in material and aerodynamic characteristics between the two Almond Varieties. The measurement of material suspension velocity will provide a theoretical basis for the development and optimization of almond shell and kernel separation equipment.

Key words: almond; aerodynamics; characteristic of material; suspension speed

摘要： 【目的】研究巴旦木破壳后壳仁物料的物理特性以及空气动力学特性,为巴旦木壳仁分离装置研发奠定基础。【方法】选择2个巴旦木品种莎车3号和莎车18号,对比物料特性,分析2个巴旦木在壳仁外形尺寸、摩擦角、物料成分、密度以及悬浮速度等区别和特点。【结果】2品种壳仁物料外形尺寸、物料成分占比差异不大,数据比较接近,莎车18号的摩擦角和密度都略大于莎车3号。莎车18号的大壳、中壳、小壳和仁悬浮速度均值依次为10.42、9.11、8.54和13.88 m/s,莎车3号的悬浮速度均值依次为10.03、8.82、8.15和13.50 m/s。【结论】2个巴旦木品种物料及空气动力学特性存在差异,莎车18号所有物料成分的悬浮速度均大于莎车3号。
