中文摘要 | 本研究先行建立印度棗劃切之基本物性 , 並依據所建立之物性及加工業者需 求研製乙部印度棗劃切機進行試驗。試驗機外型長、寬、高尺寸各為 1,355mm 、 1,435mm 及 1,340mm, 由劃切刀具、輸送、推切、出料集果及動力源等主要作業裝置組成。操作時以人工輔助供料 , 劃切動作利用氣壓缸推切果實 , 按果實大小 使通過大、中、小直徑分別為 66mm 、 60mm 及 48mm 的孔徑刀具。試驗結果顯示 , 蜜棗品種果實通過三種刀具之最大平均推力分別為135kg 、12.0kg 及 10.6Kg , 當劃切作業速率調節為 2 秒 / 次時 , 單人作業工作能力 3,089 粒 / 小時 , 相當於 250kg 果實 , 可大幅改善傳統人工劃切之工作效率及辛勞度; 機 械劃切之果實呈現良好直線性的劃切軌跡線 , 不會造成果實機械損傷 , 符合衛生 條件。於加工廠現埸試用後 , 顯示在果實劃切效果及作業效率上均滿足設計之目標。 |
英文摘要 | The first purpose of this study was to identify the physical properties of Indian jujube. Then, based on the identified physical properties and the requirements of jujube preservation industry, an automated slitting machine was developed and tested. The outside dimensions of the developed slitting machine were 1355 mm, 1435 mm, and 1340 mm respectively. The developed slitting machine was consisted of slitting blades, conveying mechanism, push-slitting mechanism, output mechanism, collecting mechanism, and the power source. In the test operation, jujubes were fed to the developed unit manually. The push-slitting mechanism was pneumatically actuated. Jujubes were classified into large, medium, and small diameters and pushed through respective slitting blades, which were 66 mm, 60mm, and 48 mm bore sizes respectively. The results showed that the maximum average push-slitting force for Indian Jujube were 13.5 Kg, 12.0 Kg, and 10.6 Kg respectively. The results also showed that the total output of the developed unit was 3089 jujubes, which was equal to 250 kg of jujubes, per hour per worker when the slitting speed was set at 2sec/slit. This result proved that the developed slitting machine out performed manual slitting in terms of productivity and labor fatigue. Straighter slit lines could reduce mechanical injury of the jujubes and have better sanitary safety. The on site test results showed that the slitting quality and productivity of the developed slitting machine had reached their design requirements |
