BEVERAGE SUPPLY DEVICE

To prevent a powder ingredient inside a powder ingredient container from solidifying, without the powder ingredient inside the powder ingredient container being carried out more than required.SOLUTION: A beverage supply device 10 comprises: a powder ingredient container 32 for storing the powder ingredient of a beverage; a powder ingredient carry-out part 33 for carrying out the powder ingredient from the powder ingredient container 32; and ingredient water supply parts 40, 50 for supplying an ingredient water for dissolving the powder ingredient. The device supplies the beverage generated from the powder ingredient carried out from the powder ingredient container 32 by the powder ingredient carry-out part 33 and the ingredient water supplied from the ingredient water supply parts 40, 50. Humidity control hollow fiber membranes 70A to 70C that allow permeation of water vapor are provided for preventing solidification of the powder ingredient inside the powder ingredient container 32. By passing dehydrated gas through the humidity control hollow fiber membranes 70A to 70C, the water vapor that may flow into the powder ingredient inside the powder ingredient container 32 is removed, thereby preventing the powder ingredient from becoming solidified.SELECTED DRAWING: Figure 6 【課題】粉末原料容器内の粉末原料が無駄に搬出されることなく、粉末原料容器内の粉末原料が固化するのを防止する。【解決手段】飲料供給装置１０は、飲料の粉末原料を貯える粉末原料容器３２と、粉末原料容器３２から粉末原料を搬出する粉末原料搬出部３３と、粉末原料を溶解させる原料水を供給する原料水供給部４０，５０とを備え、粉末原料容器３２から粉末原料搬出部３３によって搬出される粉末原料と原料水供給部４０，５０から供給される原料水とにより生成される飲料を供給するものであり、粉末原料容器３２内の粉末原料の固化防止のために水蒸気が透過可能な調湿中空糸膜７０Ａ～７０Ｃを備え、この調湿中空糸膜７０Ａ～７０Ｃ内に乾燥した気体を通過させることで粉末原料容器３２内の粉末原料に流入するおそれのある水蒸気を取り除いて粉末原料が固化するのを防ぐようにした。【選択図】図６
