针对撞击式油茶果破壳装置破壳率低和碎籽率高的问题,设计了一种破壳装置。该装置由破壳组件、加料装置、动力及驱动装置、机架等组成。破壳组件主要包括外壳体、转子、叶轮,三者同轴安装,形成破壳空腔,利用转子和叶轮的高速旋转,使油茶果与转子及外壳体内壁发生撞击完成破壳。在运动过程中确保足够大的撞击力从而提高破壳率,采用圆弧面导料板可有效降低碎籽率。以油茶果含水率、主轴转速和导料板安装角度为影响因素,以破壳率和碎籽率为评价指标,对破壳装置进行L9(34)正交试验,结果,当油茶果含水率约为60%、主轴转速为425 r/min、导料板安装角度为75°时,破壳率可达95.37%,碎籽率可降至4.27%。

Aiming at the problem of low shelling rate and high seed-breaking rate of the impact shelling device for Camellia oleifera fruit, a shell-breaking device was designed, which consists of a shelling component, a feeding device, power and driving device, and a frame. The shelling component mainly comprises an outer casing, a rotor and an impeller, which are coaxially mounted to form a broken shell cavity. The Camellia oleifera fruit were accelerated by the rotor and the impeller rotating with high speed and broken by impacting with the rotor, the ...
