PROBLEM TO BE SOLVED: To improve beverage supply efficiency in a beverage dispenser for supplying beverage such as coffee, tea and soup for example wherein powder, granules or liquid material is mixed in liquid such as hot water, to reduce a fluctuation in beverage concentration (material concentration) and to correctly adjust the concentration. SOLUTION: The beverage dispenser comprises a cylinder 1 having a closed end portion formed with a beverage discharge port 4 and a liquid inlet port 7 as a mixing chamber 20 wherein a material inlet port 9 is formed on an upper face toward an open end from the chamber 20 and this formed part is a material supply chamber 21, a piston 12 having a material carrier 14 formed with a plurality of recesses 13 independent of one another where a material is put (filled) in a peripheral face and piston driving means 15 to 19 which reciprocate the piston 12 between a position where the material carrier 14 exists in the material supply chamber 21 and a position where it exists in the mixing chamber 20. |
