摘　　要：香榧Torreya grandis‘Merrillii’青果外有一层假种皮,香榧果仁加工需要去除假种皮。果农大多采用堆沤腐烂手工脱皮法去除假种皮,这不仅效率低且腐烂的假种皮无法再利用,另外,假种皮腐烂污液渗入果壳而污染果仁,从而降低香榧的品质与商品价值。为了提高香榧加工效率并充分利用其经济价值,研制一种香榧自动去皮设备具有很好的应用前景。在测量了香榧物理等外形特性参数基础上,设计了一套去香榧假种皮设备并进行了结构参数设计分析,并对产自浙江省绍兴市、嵊州市和临安市等的带皮鲜香榧进行了去皮实验。结果表明:该设备生产效率较高,去除假种皮率达98.5%以上,果壳破损率小于1.5%。结果还表明:去除假种皮效果与香榧成熟度、电机转速以及拨打橡胶条与外壁间距等有关。An aril on the outside of the Torreya grandis ＇Merrillii＇ fruit must be removed when processing the ＇Merrillii＇ nuts. At present, the T. grandis ＇Merrillii＇ fruit is usually placed in rotten compost and peeled by hand. Since rotten aril cannot be reused, this is inefficient. In addition, decay allows aril liquid to seep into the shell producing spoiled nuts and reducing their quality and commercial value. Therefore, development of an automatic peeling device to improve T. grandis ＇Merrillii＇ production efficiency and make full use of its eco- nomic value, would be beneficial. Based on the physical parameters from three sources of T. grandis ＇Merrillii＇ （Shaoxing, Shengzhou, and Lin＇an）, and the data of stress and transmogrification obtained by experimentation of the locomotion and force. Peeling parts and equipment was designed and analyzed. A peeling experiment then showed a high production efficiency for this machine with a peeling rate over 98.5% and a breakage rate of less than 1.5%. Peeling efficiency depended on maturity of T. grandis ＇Merrillii＇, motor speed, and spacing between the peeling strips and the rings of the wall.
