A garlic fermentation device and a fermentation method thereof are disclosed. The garlic fermentation device comprises a main body, a water tank having a water-supply pipeline, a heater and a control device. The main body internally comprises a heating chamber and a fermentation chamber that is communicated with the heating chamber and utilized for placing garlic, in which the heating chamber is full with a hot gas when the heater is operated, a liquid received in the water tank is vaporized to produce a water vapor, and the hot gas and the water vapor flow to the fermentation chamber. The control device comprises a controller, a water level sensor and a temperature sensor, in which sensing signals from the water level sensor and the temperature sensor are transmitted to the controller. According to the sensing signal from the water level sensor, the water-supply pipeline controlled by the controller is utilized to replenish liquid to the water tank. Besides, according to the sensing signal, a predetermined temperature and a predetermined heating time of the temperature sensor, the heater controlled by the controller is utilized to keep the fermentation chamber at a predetermined range of temperature and also to allow the garlic in the fermentation chamber to be fermented at a suitable fermentation temperature and humidity. Thus, a practical benefit of assuring a complete garlic fermentation can be achieved.一種蒜頭發酵設備及其發酵方法,該發酵設備係於本體內設有加熱室及供擺放蒜頭之發酵室,該加熱室係連通該發酵室,並於內部設有具供水管路之水箱及加熱器,於加熱器進行加熱時,於該加熱室內產生熱氣,該水箱內的水液則蒸發而產生水蒸氣,並使熱氣及水蒸氣流通至發酵室內,一控制裝置係設有控制器、水位感測器及感溫器,該水位感測器及感溫器分別將感測訊號傳輸至控制器,該控制器即根據該水位感測器之感測訊號進行控制該供水管路於該水箱內補充水液,另根據該感溫器之感測訊號、預設溫度值及預設加熱時間進行控制加熱器動作,使該發酵室內保持於預設溫度範圍內,並使發酵室內之蒜頭於適當的發酵溫度及濕度進行發酵處理,而達到確保蒜頭完全發酵之實用效益。30‧‧‧本體301‧‧‧加熱室302‧‧‧發酵室303‧‧‧架置板3031‧‧‧通道304‧‧‧導水板305‧‧‧集水槽306‧‧‧連通管307‧‧‧排氣口31‧‧‧水箱311‧‧‧供水管路312‧‧‧排水管路32‧‧‧加熱器33‧‧‧蓋板35‧‧‧承架351‧‧‧承盤352‧‧‧滾輪41‧‧‧水位感測器411‧‧‧低水位感測元件412‧‧‧高水位感測元件42‧‧‧感溫器
