Abstract

A draught beer dispensing system according to the present invention comprises a pressure regulating valve for regulating pressure of carbon dioxide gases supplied from a source of supplying carbon dioxide gases to a draught beer receiving receptacle, a temperature detector provided adjacent to the receiving receptacle to detect a temperature of draught beer within the receiving receptacle, and an arithmetically control device for controlling the pressure regulating valve on the basis of a detected value of the temperature detector, wherein in dispensing the draught beer from the draught beer receiving receptacle, a temperature of the draught beer within the receiving receptacle is detected by the temperature detector, the detected value is inputted into the arithmetically control device, supplied pressure of carbon dioxide gases supplied into the draught beer receiving receptacle is arithmetically operated on the basis of the relationship between beer temperature and pressure stored in advance in the arithmetically control device, and an output signal corresponding to the thus operated result is outputted to the pressure regulating valve to control the latter whereby carbon dioxide gases having pressure optimum for the temperature of draught beer when dispensed can be supplied to the draught beer receiving receptacle with eliminating flat beer and excessively foamy beer.

Claims

1. A draught beer dispensing system for feeding draught beer within a draught beer receiving receptacle to a dispenser under the pressure of carbon dioxide gases supplied from a source of supplying carbon dioxide gases, and cooling the draught beer within the dispenser to dispense the same;

characterized by a pressure regulating valve for regulating pressure of the carbon dioxide gases supplied from said carbon dioxide gas supplying source to the draught beer receiving receptacle, a temperature detector provided adjacent to said receiving receptacle to detect a temperature of the draught beer within the receiving receptacle, and an arithmetically control device for controlling said pressure regulating valve on the basis of the detected value of said temperature detector; and

wherein relationship between a predetermined beer temperature and pressure is stored in advance in said arithmetically control device, the detected value of said temperature detector is inputted into said arithmetically control device, supplied pressure of carbon dioxide gases supplied into the draught beer receiving receptacle is arithmetically operated on the basis of said relationship between the beer temperature and pressure, and an output signal corresponding to the thus operated supplied pressure is outputted to said pressure regulating valve to control the pressure regulating valve.

2. A draught beer dispensing system according to claim 1 wherein said pressure regulating valve comprises a single automatic pressure regulating valve capable of performing a multi-stage pressure regulation.

3. A draught beer dispensing system according to claim 1 wherein said temperature detector comprises a thermistor.

4. A draught beer dispensing system for feeding draught beer within a draught beer receiving receptacle to a dispenser under the pressure of carbon dioxide gases supplied from a source of supplying carbon dioxide gases to cool the draught beer within said dispenser and dispense the draught beer from a beer dispensing valve;

characterized by a pressure regulating valve for regulating pressure of carbon dioxide gases supplied from said carbon dioxide gas supplying source to the draught beer receiving receptacle;

a temperature detector provided adjacent to said receiving receptacle to detect a temperature of the draught beer within the receiving receptacle; and

an arithmetically control device for controlling said pressure regulating valve on the basis of the detected value of said temperature detector and controlling opening and closing of said beer dispensing valve, and wherein the relationship between a predetermined beer temperature and pressure is stored in advance in said arithmetically control device, the detected value of said temperature detector is inputted into said arithmetically control device, the supplied pressure of the carbon dioxide gases supplied into the draught beer receiving receptacle is arithmetically operated on the basis of said relationship between the beer temperature and pressure and the open time of said beer dispensing valve is arithmetically operated, an output signal corresponding to the thus operated supplied pressure is outputted to said pressure regulating valve to control the pressure regulating valve, and said beer dispensing valve is controlled to be opened during said operated open time.
