中文摘要 | 龍眼經烘焙加工後,果粒呈不規則形狀,因含糖量高,粘性增加,如以人工剝肉,工作十分辛苦,作業速度十分緩慢,其每人作業量為2-2.5 kg/hr。使用真空式之剝肉方式,除了可減少勞力之需求,且可降低加工成本,又能合乎衛生原則。 真空吸力式剝肉機之機構包括進料及果粒放置裝置、果肉環切裝置、真空剝肉裝置、真空產生裝置及控制箱等部分。由試驗顯示:(1)剛烘焙後的龍眼乾肉與市場銷售的龍眼肉,進行含水率測,其結果,剛烘焙後的龍眼乾肉平均含水率為32.93%市場銷售的龍眼肉平均含水率為35.04%。(1)龍眼乾果肉拉力試驗,龍眼乾果肉厚度0.5 mm,當拉力達194.9 g,梯度41.64622 g/s時果肉被拉斷,果肉厚度1 mm,當拉力達649.3 g,梯度125.17921g/s時,果肉被拉斷。(3)剝肉試驗以果肉含水率33%,真空度10⁻³ torr時,剝肉效果為最佳,其剝肉效率約為80%,真空度10⁻² torr與10□ torr之剝肉效果相同,兩者之剝肉效率約為70%,但以真空度10⁻² torr,所剝的果肉較完整。(4)真空吸力式剝肉機,每小時作業量為60公斤,人工剝肉量如以每小時2.5公斤計算,真空剝肉方式之作業量約人工剝肉作業量的24倍。 |
英文摘要 | After the baking procession, the longans appear irregularly-styled. Besides, the ascension increases because of the high sugar-content. If the flesh-peeling work is dene by hand, not only the work will be hard but also the working speed will be very slow. The average working capacity per person is 2-2.5kg/hr. If the vacuum flesh-peeling work is introduced, we'll both decrease labor need and lower the procession cost. What's more, it corresponds with the wholesome regulations. The structures of a vacuum-sucking and flesh-peeling machine contain material import, and installations of setting the lingams, of cutting the flesh in a ring-styled way, of vacuum flesh-peeling, of vacuum-producing and of control box. The experiment shows (1) If we measure the moisture content between the just-baked dried lingams and the ones sold in the market, the result says the former ones contain 32.93% and the latter 35.04%. (2) From the tension test of the dried lingams, we found that the flesh will be dragged down if the flesh thickness is 0.5mm, the tension force reaches 194.9g and the gradient is 41.64622 g/s. And the flesh will also be dragged down if the flesh thickness is 1mm, the tension force teaches 649.3g and the gradient 125.17921 g/s. (3) The flesh-peeling result is the best when the flesh moisture content is 33%, and the vacuum degree is 10⁻³ torr. The efficiency is about 80%. But the results of the vacuum degrees 10⁻² torr and 10□ torr are the same. Both have the efficiency about 70%, but the former has a more complete peeled flesh. (4) The working capacity of a vacuum suckling flesh-peeling machine is 60 kg, but the working capacity by hand is 2.5kg per hour. Therefore, the working capacity of the former is 24 times as much as hat of the latter. |
