针对目前山核桃破壳取仁困难导致山核桃产业生产效率低这一现状,设计了一套系统性的试验方案,用以探究高破壳率、低果仁损伤率的山核桃破壳的力学特性参数,包括采用电镜试验和微机控制电子万能试验机(CMT5105)等分析了山核桃的物理结构和力学特性。结果表明,不同含水率和破壳加载力方向对山核桃破壳有显著影响。山核桃含水率为14.59%时,长轴方向破壳效果最佳。该研究为山核桃后续相关试验及其破壳装备研发提供了理论依据。
Aiming at the present situation that the production of pecan walnut is difficult due to the difficulty of removing pecan kernels, a systematic experimental scheme was designed to explore the mechanical properties of pecan shells with high breaking rate and low kernel damage rate Characteristic parameters, including the use of electron microscopy and computer controlled electronic universal testing machine (CMT5105) analysis of the physical structure and mechanical properties of pecan. The results show that the different moisture content and the direction of breaking force exert a significant influence on the breaking of pecan shell. Hickory moisture content of 14.59%, the best long-axis crustal effect. The research provided the theoretical basis for the follow-up related test of Hickory and the research and development of broken shell equipment.
