冰水機應用於清酒製程之節能改善效益分析
Benefit analysis of chiller energy saving in making sake
摘要
國內外清酒量產工廠眾多且各地產酒過程與方法皆不盡相同，本論文在以不影響酒液品質需求下當使清酒製程與製冷冰水主機之耗能問題整合將能為公司企業節省營運成本，並可帶動節能減碳相關產業發展共創節能、環保、企業「三贏」局面。本研究利用清酒釀造程序以冷凍空調冰水機汰換來探討節約能源，且結合增大儲冰水槽容量方式降低清酒製程高峰期電力需求；在清酒釀造過程中由米麴飯培養、蒸熟冷卻、醱酵熟成、低溫貯藏空間以及儲冰水槽製造冰水等，每階段工序無不與空調冰水機息息相關，當釀酒醱酵品溫掌控於曲線範圍內定可增加優質酒之產製比例；對於冰水主機改善後將利用清酒原料之水，做為電力負載驗證節能積效效率，主機單組運轉COP值為2.3；在產品應市場多樣化所需，轉型部分醱酵及縮減批次量，冰水槽溫度提高6℃醱酵槽降溫11℃，全年製酒大樓與冰水機系統確有顯著用電需求省電能耗達38.1％，當儲冰水系統應用於清酒製程有3.78％電力節能效果，未來本研究可提供製酒工業能源成本之規劃參考設計。

There are numerous sake production plants around the world, and their production processes and methods differ. If the sake process considers the energy consumption of the chiller system without influencing the sake quality, the operating cost can be saved. The development of energy saving and carbon reduction technologies can achieve win-win outcome in energy saving, environmental protection, and business. This study discussed energy saving by replacing the chiller system in the sake brewing process, and increased the ice storage tank capacity to reduce the electricity requirement in the peak hours of sake brewing process. The sake brewing process consists of koji rice cultivation, steaming and cooling, fermentation ripening, low temperature storage space and making chilled water by ice storage tank. Each process step requires the use of the chiller system. When the fermentation product temperature is controlled within the curve range, the yield rate of quality sake must be increased. After chiller improvement, the water used as the raw materials of sake brewing is used as electrical load to validate the energy saving performance. The single unit operation COP value of host is 2.3 For market diversification, the product is transformed into partial fermentation and the batch quantity is reduced. The chilling tank temperature is increased by 6℃, the fermentation tank temperature is reduced by 11℃. The annual power consumption of liquor building and chiller system is reduced by 38.1% significantly. When the chilled water storage system is used in the sake brewing process, the power consumption can be reduced by 3.78%. This study provides reference design for alcoholic beverage industry to plan the energy cost in the future.
