A liquid chiller 1 of the present invention includes: a cylindrical refrigerating tube 31 which can cool an outer wall thereof a cylindrical shield tube 21 covering the refrigerating tube 31 and rotated around a rotating axle Zr to perform a rotation movement and a liquid inlet 73 guiding liquid into a gap between the outer wall of the refrigerating tube 31 and an inner wall of the shield tube 21. In addition, the temperature of a surface of the outer wall of the refrigerating tube 31 is cooled below the freezing point of the liquid. Moreover, the shield tube 21 has a spiral protrusion 22 on the inner wall thereof.本發明之液體急冷裝置1係具備:筒狀之冷卻管31,係可將外壁予以冷卻;筒狀之被覆管21,係包覆冷卻管31且能以旋轉軸Zr為中心進行旋轉運動;及液體導入路73,係可將液體導入至冷卻管31之外壁與被覆管21之內壁之間的間隙G。再者,冷卻管31之外壁的表面溫度係被冷卻至前述液體之凝固點以下。此外,被覆管21係在內壁具有螺旋狀之凸部22。1‧‧‧液體急冷裝置21‧‧‧被覆管21a‧‧‧附屬配件211‧‧‧安裝部212‧‧‧縮徑部213‧‧‧整流部22‧‧‧凸部23、43‧‧‧齒輪24‧‧‧保持環25‧‧‧導引環26、28‧‧‧托架27‧‧‧導引板31‧‧‧冷卻管31b‧‧‧底面32‧‧‧罩蓋33‧‧‧密封構件34、35‧‧‧補強構件36‧‧‧托架41‧‧‧馬達42‧‧‧軸51‧‧‧控制部53‧‧‧液體槽54‧‧‧預冷裝置55‧‧‧閥56‧‧‧冷卻裝置57‧‧‧重量計58‧‧‧加壓瓶59‧‧‧溫度感測器61‧‧‧作動開關62‧‧‧閥設定部63‧‧‧重量設定部71‧‧‧冷媒導入路72‧‧‧冷媒排出路73‧‧‧液體導入路74‧‧‧連結路75‧‧‧液體槽連結部76‧‧‧液體供給路77‧‧‧氣體供給路100‧‧‧框體101‧‧‧容器保持部G‧‧‧間隙G1‧‧‧第1端部G2‧‧‧第2端部Zr‧‧‧旋轉軸
