Abstract

PROBLEM TO BE SOLVED: To provide a beverage supply apparatus for pouring the liquid raw material charged in a raw material container such as a bag-in box or the like to serve the same, preventing a supplied beverage from becoming lukewarm even if a beverage supply interval becomes long and always controlled to the optimum temperature to serve the beverage uniformly mixed in a predetermined mixing ratio and cooled to temperature suited to drink. SOLUTION: The liquid raw material pouring part 7 communicating with a liquid raw material pour tube 6 and functioning so as to discharge a predetermined amount of the liquid raw material in the BIB 5 , a flowmeter 12 and a supply solenoid valve 13 turned ON/OFF to supply dilution water are housed in the bag-in box refrigerating chamber 3 housing and cooling the BIB 5 . Gaps are provided between a liquid raw material supply nozzle 8 for supplying a beverage to a cup 23 , a dilution water supply nozzle 14 and a heat insulating material 33 to be cooled to temperature lower than the peripheral temperature by cold air of the bag-in box refrigerating chamber 3.
