To prevent an extractor to which beverage raw material and hot water are supplied and which extracts a beverage from being cooled and to extract the hot beverage which is always at a suitable temperature through the effective use of energy.
An extractor chamber 25 is installed in a machine body 11, and an extractor 28 and an auxiliary heater 51 are arranged in the extraction chamber 25. An exhaust means 35 exhausting the inner part of the extractor 28 is installed in the extractor 28. A temperature sensor 18 detecting an atmosphere temperature is installed outside the extractor chamber 25. When the atmosphere temperature detected by the temperature sensor 18 is not more than a prescribed temperature, the auxiliary heater 51 heats the inner part of the extractor chamber 25, retains the heat of the extractor 28 and prevents the temperature of the extracted beverage extracted by the extractor 28 from lowering. The exhaust means 35 is operated only at the time of extracting the beverage by the extractor 28 and the lowering of the heat retaining property of the extractor 28 in the extractor chamber 25 is suppressed to a minimum.
