为探明油茶果如何破壳,找到油茶果不同物理特性以及不同加载条件下破壳力的变化情况,为油茶果脱壳加工工艺提供理论依据,进行了准静态压缩试验,对影响油茶果破壳力的因素加载方向、加载速率、油荼果含水率以及油茶果直径等进行了分析.结果表明:沿茶果根顶连线方向加载最省力;加载速率、油茶果含水率和直径大小对破壳力的影响极为显著,破壳力随加载速率的增加先升高后降低,随含水率和直径的增加而升高.加载速率x1与破壳力y的函数关系式为:y=-0.07x21 +9.73x1 +422.62,油茶果含水率x2与破壳力y之间的函数关系为:y=0.12x22+0.89x2+46.9.

To find how to crack for camellia fruit, and find out the change of breaking strength under different physical properties and loading conditions,as to provide theoretical basis for dehulling process of camellia oleifera,a quasi-static compression test was carried out, which analyzed the effect factors of camellia fruit breaking force, such as loading direction and loading speed,moisture content and diameter of fruit of camellia fruit . The results showed that~ at the di- rection from root to roof of camellia fruit , the force was the smallest, ...
