中文摘要 | 傳統熱風萎凋槽以燃燒瓦斯配合鼓風機送風,產生30℃~38℃的熱風萎凋茶 葉。傳統熱源與鼓風機設計在萎凋槽的前側,其設計會造成熱風萎凋槽在萎凋過程 中各點溫度的不均。為解決其問題,本試驗在萎凋槽上方覆蓋尼龍布,目的是讓萎 凋過程的溫度較均勻。 試驗材料使用機採青心烏龍茶菁,設計2 種不同製程的實驗:A 處理 (對照組) 為無尼龍布的萎凋,B 處理 (試驗組) 為蓋尼龍布的萎凋,A、B 的後續製程相同做 成文山包種茶。官能品評結果顯示A 處理 (對照組) 的茶葉品質變異性較大、水色 蜜綠帶黃、滋味帶澀;B 處理 (試驗組) 的茶葉品質變異性較小、水色蜜綠明亮、 活性強。此技術未來可改善茶農之茶湯品質不穩定問題。 |
英文摘要 | Traditional hot-air withering tank with blower can produce hot-air with about 30 to 38 degree Celsius to wither the tea. The heat resource and blower is located on the one side of withering tank, it would cause uneven distribution of hot-air. To solve this problem, we cover nylon cloth on the withering tank. We used mechanical-plucking Chin-shin Oolong tea asm aterialin two different processing experiments: A: uncovered withering tank B: covered withering tank with nylon cloth After withering, Aand B arreea tetd whit smae proecss to produce Wenshan-Paochung tea which will be conducted sensory evaluation. The result showed that the tea with A treatment has features such as large variation of quality, astringent taste, yellow-green color. Otherwise, tea with B treatment has features like quality with low variation, color of bright honey-green and rich taste. This technology would improve the problem of unstable quality of tea. |
