ABSTRACT:
A beer vending machine of the invention includes a cylinder containing compressed carbon dioxide gas, a gas regulator for adjusting a secondary pressure of the carbon dioxide gas, a temperature sensor for monitoring a beer temperature, gas and leak valves, and a pressure controller. The gas valve is disposed in a gas pipe line between the beer barrel and the gas regulator to open or close the gas pipe line, and the leak valve is disposed in a branch pipe for depressurizing the beer barrel. Based on the beer temperature obtained by the temperature sensor, the pressure controller controls the gas regulator, the gas valve and the leak valve to set the secondary pressure at an equilibrium pressure corresponding to the obtained beer temperature. Therefore, the beer barrel is pressurized under the suitable equilibrium pressure.
