To provide an object such as a food product at a low cost by drying it under vacuum at a room temperature, without using a heating device or a freezing device.SOLUTION: There is provided a room-temperature vacuum drying system comprising a vacuum pot 1 allowing an object M to get thereinto and to exit therefrom, a water-sealed vacuum pump 2 of an Elmo type connected to the vacuum pot 1 to evacuate the vacuum pot 1, and a refrigeration water tank 5, which is connected to the water-sealed Elmo type vacuum pump 2 and refrigerates water sealed in the water-sealed Elmo type vacuum pump 2 to prepare circulation water. The object M is dried under vacuum at a room temperature by putting the object M into the vacuum pot 1 and evacuating the vacuum pot 1 at a room temperature by driving a water-sealed Elmo type vacuum pump 2.SELECTED DRAWING: Figure 1 【課題】加熱装置や冷凍装置を用いずに、食品等の対象物を常温で真空乾燥して低コストに提供することである。【解決手段】対象物Ｍを出し入れ可能な真空釜１と、その真空釜１に接続され、当該真空釜１の内部を真空吸引する水封式エルモ型真空ポンプ２と、その水封式エルモ型真空ポンプ２に接続され、当該水封式エルモ型真空ポンプ２の内部に封入された水を冷却して循環水とする冷却用水槽５と、を備える常温真空乾燥システム。真空釜１の内部に対象物Ｍを投入して、水封式エルモ型真空ポンプ２の駆動により真空釜１の内部を常温で真空吸引することで、対象物Ｍを常温真空乾燥する。【選択図】図１
