PROBLEM TO BE SOLVED: To avoid exhaust-related troubles such as deposition and clogging of powdered raw material by balancing the volume of gas drawn through an exhaust duct from each of a plurality of mixing bowls when vapor occurred in the mixing bowl is discharged. SOLUTION: This drink dispenser is provided with a plurality of raw material canister, and mixing bowls 3, and a powdered raw material and hot water is fed into the bowls 3 to prepare a drink to be fed into cups. A vapor discharge port 3e opened into each bowl is connected to an exhaust duct 14 to discharge vapor occurred in the bowl through an exhaust fan. In the duct 14 being a manifold, connection ports 14c-1-14c-3, into which vapor discharge ports of the bowls are inserted respectively are opened so as to be spaced in the longitudinal direction and an outlet pipe 14d leading to an exhaust fan of a following stage extends from one of the ends of the duct. A nozzle-shaped throttle part 14a, as a suction gas volume adjusting means, is formed in an opening of each of the connection ports, and the diameters d1, d2, d3 of the throttle part are made smaller as the distance from the outlet pipe decreases (d1>d2>d3) to balance the volume of exhaust gas. |
