BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beverage piping system.

[0002]

2. Description of the Related Art A moving container for beverages, for example, a beer barrel, is connected to a beer pouring device installed in a beverage store or the like by a hose serving as a beverage distribution pipe, and the beer liquid stored in the beer barrel. Is supplied to the pouring device. That is, the pouring device is provided with a fluid coupling, and beer liquid is supplied from a beer barrel via a hose connected to the coupling. Then, the beer supplied from the beer barrel to the pouring device via the hose is cooled by a cooler provided in the pouring device and poured out from the pouring port to the outside. The hose is generally formed of a synthetic resin.

[0003]

However, if beer is passed for a long time through a hose made of synthetic resin connected to a pouring device, contamination by microorganisms such as wild yeasts and bacteria is generated inside the hose. Adheres to the inner surface of In this state, the taste and quality of the beer passed through the hose will be reduced. Therefore, the hose connecting the beer keg and the pouring device is washed or replaced with a new hose after a certain period of use. For this reason, the time and labor required for cleaning and the loss of beer generated during cleaning or the cost of hoses used for replacement are large, the economics of maintaining the hoses are low, and the time and effort required for hose replacement require a lot of trouble. Maintenance was troublesome.

The present invention has been made in view of the above-mentioned circumstances, and it is possible to suppress the generation of stains by microorganisms such as wild yeasts and bacteria in a distribution pipe through which a beverage flows, with a simple configuration, and thereby to reduce the number of beverages distributed through the beverage distribution pipe. The present invention provides a beverage piping device that can distribute a beverage without impairing the quality of the beverage, prolong the period of use, improve the economics in maintaining the beverage distribution pipe, and facilitate the maintenance of the beverage distribution pipe. Aim.

[0005]

In order to achieve the above-mentioned object, a beverage piping apparatus according to the present invention comprises a first distribution pipe through which a beverage is distributed, and a first distribution pipe outside the first distribution pipe. A second flow pipe disposed around the pipe, a third flow pipe disposed outside the second flow pipe and surrounding the second flow pipe and communicated with the second flow pipe; Wherein the second flow pipe and the third flow pipe are cooling fluid flow pipes through which a cooling fluid flows to cool the beverage flow pipe.

[0006]

The cooling fluid is circulated through the cooling fluid flow pipe to cool the beverage flow pipe, thereby suppressing the generation of dirt due to the remarkable growth of microorganisms such as wild yeasts and bacteria in the beverage flow pipe. The use period in which the beverage can be distributed without deteriorating the quality of the beverage can be greatly extended as compared with the related art.

[0007] That is, the cause of the contamination caused by microorganisms such as wild yeasts and bacteria in the distribution pipe through which the beverage passes is caused by removing the dispense head for pouring beer from the barrel when replacing the used barrel. The inside of the tip comes into contact with air, etc., and microorganisms such as wild yeasts and bacteria floating in the air enter the beer hose. On the other hand, the beer hose is affected by heat and the like discharged from the beer cooling device, and has an optimum temperature at which these microorganisms easily grow remarkably in a short time, and is generated when a large amount of microorganisms are generated in the beer hose.

[0008] For this reason, by rapidly cooling the beverage distribution pipe to a certain temperature, it is possible to suppress the remarkable growth of microorganisms such as wild yeasts and bacteria in the beverage distribution pipe and the generation of dirt .

Further, in the present invention, a cooling fluid is circulated outside the first circulation pipe through which the beverage is circulated to cool the beverage circulation pipe. Since the pipes are arranged concentrically, the whole apparatus is assembled in a compact unit, and storage, transportation, and handling such as connection are easy.
