Description

  The present invention is, for example, an effervescent beverage pouring that extrudes an effervescent beverage by the pressure of carbon dioxide gas from an effervescent beverage container containing an effervescent beverage in which carbon dioxide is dissolved, such as commercial beer and juice In connection with the improvement of the apparatus, especially when adjusting the pressure in the sparkling beverage container, a pressure reducing valve or pressure regulator provided in a pressure pipe connecting the carbon dioxide gas supply source such as a carbon dioxide cylinder and the sparkling beverage container. Effervescent beverage pouring that prevents fruit juice and other additive components (hereinafter referred to as impurities) contained in the beverage mist from adhering and allows the inside of the effervescent beverage container to be depressurized without pouring out the beverage It relates to the device.

  Generally, a sparkling beverage pouring device for carbonated beverages such as commercial beer connects a sparkling beverage container such as a beer barrel, a carbon dioxide supply source such as a carbon dioxide cylinder, and a sparkling beverage container and a carbon dioxide supply source. A pressurizing tube, a pressure regulator interposed in the pressurizing tube, etc., and applying a carbon dioxide gas at a predetermined pressure from a carbon dioxide supply source to the upper air layer inside the sparkling beverage container, so-called siphon type In other words, a method of extruding from a pour pipe extending outward from the liquid layer portion below the sparkling beverage container (see, for example, Patent Document 1).

  In addition, in the sparkling beverage dispensing apparatus, the foaming properties differ depending on the temperature of the sparkling beverage in the sparkling beverage container and the content of carbon dioxide in the sparkling beverage. In addition to increasing the internal pressure of the sparkling beverage container, it is necessary to adjust the amount of foam generated by decreasing the internal pressure of the sparkling beverage container.

  In the effervescent beverage dispensing apparatus having such a configuration, when the internal pressure of the effervescent beverage container is increased, the pressure regulator provided in the pressurizing pipe is adjusted to increase the applied pressure of the carbon dioxide supply source. On the contrary, when lowering the internal pressure of the effervescent beverage container, the gas is removed from the pressure regulator provided in the pressurizing pipe, or the effervescent property is extracted from the extraction pipe provided in the effervescent beverage container. It was done by pouring out beverages.

  However, in the configuration like the conventional sparkling beverage dispensing device, when the gas is extracted from the pressure regulator, the gas flows backward from the gas layer portion of the sparkling beverage container. However, there is a problem that impurities contained in the beverage mist adhere to the pressure regulator and the pressure regulator deteriorates and malfunctions.

  In addition, when a pressure reducing valve capable of reducing pressure in only one direction is used as the pressure regulator, the beverage mist does not adhere to the pressure reducing valve because the gas is not extracted from the pressure reducing valve that is the pressure regulator. It is necessary to extract the beverage from the dispensing pipe provided in the sparkling beverage container to reduce the pressure in the sparkling beverage container, and to remove the beverage containing excess foam until the pressure in the sparkling beverage container decreases There was a problem that it had to be poured out.

JP-A-8-13397

  The present invention has been made in view of such problems, and its purpose is to add a carbon dioxide gas supply source and a sparkling beverage container when the pressure in the sparkling beverage container is adjusted. Effervescent beverage pouring that prevents the impurities contained in the beverage mist from adhering to the pressure reducing valve or pressure regulator provided in the pressure tube, and allows the inside of the effervescent beverage container to be depressurized without dispensing the beverage. To provide an apparatus.
