自動泡茶雛形機之研發

Abstract

近年來國內喝茶的風氣盛行，且喝茶的文化已漸漸融入國人的生活當中；而喝茶不單單只是怡情養性，以簡單、快速又不複雜的方式泡出好茶即是本研究欲達成之目標。利用沖泡咖啡之滲濾式壺其水循環原理，並加入單晶片微處理器與溫度感測器整合為自動泡茶雛形機；滲濾式裝置能將茶葉與茶湯隔開，避免茶葉在熱水中浸泡的時間過長造成茶湯滋味不佳，並參照標準泡茶法之沖泡方式，固定茶葉與水的比例及沖泡溫度與時間，使用沸騰熱水分別循環萃取龍井綠茶、文山包種茶、椪風茶、凍頂烏龍茶、鐵觀音及紅茶，並找出各種茶類最適之沖泡時間；另外，還可視本身喝茶的喜好程度，自行調整沖泡時間。在這講求快速且便利的時代，不失為一項泡茶的新選擇。

Tea drinking has become popular in recent years, it has been gradually integrated into our daily lives. Besides being a drink and a hobby, tea has received increased attention due to its nutritious value. The objective of this research is to develop an automatic prototype tea maker, which is able to make high quality tea by using a simple and quick method. In this study, a design is proposed by using the coffee percolation device as the main focus with single chip microprocessor and temperature sensor served as control and combining those together as one automatic prototype tea maker. It can separate the tealeaves from the water, thus avoiding the tealeaves from immersing in hot water for too long. Temperature and brewing time can be set on the device based on the standard of making tea. Depending on the type of tealeaves and leaf-to-water ratio, brewing time were set for the extraction cycle. Different extraction times were set to produce different tea concentrations for the followings: Long-Jing Green Tea, Wen-Shan Baozhong Tea, Dong-Ding Oolong Tea, Tieh-Kuan-Yin Tea, Formosa Oolong Tea and Black Tea. In this way, consumers can adjust tea concentration and brewing temperature according to their preferences. The tea maker is able to satisfy the modern demand of efficiency and convenience and is thus a feasible new choice.
