摘要

為提高農產品的附加產值，收穫後處理為一重要之作業。印度棗爲南部的一新興果樹產業，而其相關的收穫後處理包括清洗、分級選別、包裝及蜜錢加主等作業，目前此類收穫後處理作業均以人工處理為主，今後為節省勞力、提高作業效率及改善衛生問題，收穫後處理作業機械的應用乃為必然之趨勢。在尚無適用的印度棗分級機械的現況下，本研究先行調查印度棗果實之外形、大小、果重、果形指數、傾斜角度、滾動角度、摩擦係數、果實大小分佈比率等基本物性，以建立分級之物性指標，提供分級機械設計研發之基礎資料。

To increase the additional values for agricultural products, the process of post-harvest is one of the most important works. Indian jujube is a newly risen fruit industry. The relative processes of post-harvest for Indian jujube include cleaning, grading, packing and preservation process. For the time being, such works are handled by labor power. In future, it is an inexorable trend to use post-harvest processing machine for saving labors, promoting work efficiency and improving the problem of sanitation. Because it was short of grading machine suitable for use in sorting Indian jujube, this study firstly investigated its basic physical properties and then established the physical property's indices. Those data can provide the fundamental information to design and develop the grading machine. The physical properties of Indian jujube include the shapes, sizes and weights, slanting and rolling angles, coefficients of friction and the size attribution ratio.
