A kind of cooling device of coffee bean includes a stirred tank, a collecting tank, a partition, an agitating unit, an adapter tube and a pumping cells. Wherein, below collecting tank system connection what stirred tank, which has a taper hole, the aperture of the big what under shed in the aperture of the upper opening of the taper hole； The partition system is arranged between the what stirred tank and the collecting tank, which there are a plurality of perforation to be connected to the stirred tank and the collecting tank； The agitating unit has in the driving lever position what stirred tank； The adapter tube one end connects the collecting tank and communicates with the under shed； The other end of the pumping cells system connection what adapter tube. Thereby, air can be allowed uniformly across the stirred tank, and suction can be enhanced and avoid the accumulation of coffee bean detritus in the collecting tank.一種咖啡豆之冷卻裝置，包含有一攪拌槽、一收集槽、一隔板、一攪拌單元、一接管及一抽氣單元。其中，該收集槽係連結於該攪拌槽下方，該收集槽具有一錐孔，該錐孔之上開口之孔徑大於下開口之孔徑；該隔板係設置於該攪拌槽與該收集槽之間，該隔板具有複數個穿孔連通該攪拌槽與該收集槽；該攪拌單元具有一撥桿位於該攪拌槽內；該接管一端連接該收集槽並與該下開口相通；該抽氣單元係連結於該接管之另一端。藉此，可讓空氣均勻地通過該攪拌槽，且可增強吸力及避免咖啡豆殘屑累積在該收集槽中。
