摘要：
PROBLEM TO BE SOLVED: To prevent separated substance of an object to be cooled in a vacuum cooling device from entering into a vacuum pipe without reducing an effective volume within a processing tank.SOLUTION: The present invention relates to a vacuum cooling device including a processing tank 2 for storing an object to be cooled and a vacuum generating device 1 connected to the processing tank 2 by a vacuum pipe 5 so as to suck gas in the processing tank and a heat exchanger 4 at the midway part of the vacuum pipe 5 to cool the sucked gas so as to make vacuum in the processing tank to evaporate moisture from the object to be cooled stored in the processing tank to perform a cooling operation, and a shield plate 7 for preventing separated substances such as drips or pieces separated from the object to be cooled from being fed to a deeper side of the vacuum pipe is arranged at a location near a connection part with the processing tank 2 in the vacuum pipe 5, the vacuum pipe 5 has a large diameter at a part where the shield plate 7 is arranged and a small diameter at a downstream side.COPYRIGHT: (C)2015,JPO&INPIT【課題】真空冷却装置において、処理槽内の有効容積を削減することなく、被冷却物の分離物が真空配管内に入り込むことを防止する。【解決手段】被冷却物を収容する処理槽2、処理槽2と真空配管5によって接続しており処理槽内の気体を吸引する真空発生装置1、真空配管5の途中に吸引気体を冷却する熱交換器4を持ち、処理槽内を真空化することで処理槽内に収容した被冷却物から水分を蒸発させて冷却を行う真空冷却装置において、真空配管5内の処理槽2との接続部に近い箇所に、被冷却物から分離したしずくやかけらなどの分離物が真空配管の奥へ送られるのを防止する遮蔽板7を設けており、真空配管5は遮蔽板7を設けている部分では径を大きくし、下流側で径を小さくする。【選択図】図1
