To make it possible to always fix the concentration of beverages even in different temperature conditions and to improve the quality of commodities by detecting a temperature around a beverage, reducing the quantity of ice cubics to increase the quantity of dilution water when the detected temperature is low and increasing the quantity of ice cubics to reduce the quantity of dilution water when the detected temperature is high.

An outside air temperature sensor 4 arranged on the outside or inside of an automatic vending machine body detectes the ambient temperature of a raw material feeder. A raw material in the raw material feeder and dillution water in a dillution water feeder 2 are poured into a cup and agitated and then ice cubics are supplied from an ice cubic feeder 3 to the mixture to vend a beverage. A control part 5 constituted of a microcomputer controls the quantity of dillustion water and that of ice cubics based on the detection temperature of the sensor 4 to reduce the quantity of ice cubics and increase the quantity of dillution water when melted quentity of ice cubics is small, and vice versa.
