- 摘要
- 臺灣本土具有蓬勃發展的半導體產業、化工產業、農產加工業，各產業製程中常具有乾燥技術 需求，而乾燥設備關鍵組件多來自進口，技術核心掌握在他國手中，乾燥技術需仰賴外國產業，造 成一定的產業對外依賴性。為達臺灣產業節能以及技術本土化的目的，本院執行能源署計畫開發節 能低溫吸附式乾燥相關技術，落實節能技術產業推廣。 本研究採用自行開發的通用性節能乾燥系統，除濕轉輪直徑50公分、厚度20公分，搭配模組 化吸附轉輪框架，系統整體長約3公尺、寬1.1公尺、高1.7公尺，乾燥處理風量達2,500 m3/h以上， 為達到節能目標，控制邏輯改由固定相對濕度動態調整再生加熱功率。需求端不同可調整設定參 數，提供乾燥製程空氣溫度20~45oC、相對濕度可低至10%以下。本測試以單一批次2噸的大蒜來 進行產業規模量體的乾燥測試驗證，在15天內完成乾燥，大蒜乾燥前總重為2,020公斤，經乾燥後 剩餘1,534公斤，減重24%。過去固定加熱功率吸附式乾燥系統測試4噸大蒜乾燥結果，4,070公斤 的大蒜，經15天乾燥重量降至3,032公斤，減重率為25.5%，乾燥能源因數為266 g-H2O/kWh。兩相 對比，由於提高換氣率且批次乾燥量僅一半，單位乾燥能源因數較低，乾燥能源因數為132 g-H2O/ kWh，如未來調整換氣率與過去測試一致，並將批次量提升到相同的4噸，有望可提升乾燥能源因 數。

- Taiwan boasts a rapidly developing semiconductor industry, chemical industry, and agricultural processing. In these industries, drying technology is required during various processes. However, key components of adsorption drying equipment are often imported. This reliance on foreign industries for drying technology has led to a certain degree of external dependence. To promote energy-saving and domestic technological development in Taiwan, our institute has undertaken a project commissioned by Energy Administration to develop energy-efficient low-temperature adsorption drying technologies, aiming to promote such energy-saving solutions across the industry. This study utilized a self-developed energy-efficient drying system. The system features a desiccant wheel with a diameter of 50 cm and thickness of 20 cm with a modular desiccant wheel framework. The entire system measures approximately 3 meters in length, 1.1 meters in width, and 1.7 meters in height, with a process airflow exceeding 2,500 m³/h. To achieve energy efficiency, the control logic dynamically adjusts the regeneration heating power based on fixed relative humidity targets. The system allows parameter settings to be adjusted according to different end-user requirements, providing drying air temperatures ranging from 20 to 45oC, and achieving relative humidity levels below 10%. For industrial-scale testing, a single batch of 2 tons of garlic was used to validate the system’s drying performance. The results were then compared with previous tests which dried 4 tons of garlic. Both methods completed the drying process in 15 days. The garlic’s initial weight was 2,020 kg and was reduced to 1,534 kg after drying, marking a 24% reduction. Compared with previous results, due to a higher air exchange rate and a lower batch weight, the specific energy consumption was lower—the system removed 132 g of water per kilowatt-hour. It is anticipated that if future tests align the air exchange rate with previous settings and increase the batch scale to 4 tons, the energy efficiency of the drying process could be further improved.
