Air extrusion type interlayer beer fresh-keeping barrel

Abstract

The invention discloses an air extrusion type interlayer beer fresh-keeping barrel. The air extrusion type interlayer beer fresh-keeping barrel comprises a beer barrel shell and a beer barrel flexibleinner container arranged inside the beer barrel shell. The beer barrel flexible inner container is connected with a matched beer straw through an inner container connecting part. The beer straw penetrates the beer barrel shell. A distributor is arranged outside the beer barrel shell. The distributor is fixedly arranged on the top of the beer straw. The distributor is connected with a draft beer machine through a beer hose. An air pump is connected to the draft beer machine. The air pump is connected with an air inlet valve through an air pump hose. The air inlet valve is fixed on the beer barrel shell. According to the air extrusion type interlayer beer fresh-keeping barrel, air is injected into the low-pressure air pump, the pressure of the injected air does not exceed 0.4 MPa, and the use pressure of a stainless steel shell or a plastic resin shell circulating in the market is all within 1 MPa, so that the potential safety hazards of a high-pressure air container and a pipeline aresolved effectively; and in addition, the beer does not come into contact with any foreign gas during the whole process, so that the deterioration of the taste and quality caused by oxidation or impurities caused by foreign gas is eliminated thoroughly, and meanwhile the preservation period is prolonged.

Description

technical field [0001] The invention relates to a barrel-packed beer fresh-keeping barrel, in particular to an air-extruded beer fresh-keeping barrel with interlayers. Background technique [0002] Existing barreled beer barrels (the interior is fresh beer and draft beer) are mainly made of stainless steel (reusable), plastic resin barrels (one-time use), etc., all of which are injected into the beer barrel with a pressure of 0.2MPa -0.31MPa edible carbon dioxide or clean compressed air, press the beer in the beer barrel to the draft beer machine for cooling. [0003] Problems and disadvantages of prior art: [0004] The gas source of carbon dioxide is from the gas cylinder in the high-pressure container above 5MPa, through the pressure reducing valve, down to 0.2-0.31MPa and injected into the beer keg. Improper use causes high-pressure gas to directly enter the beer keg, which in turn causes the beer keg to rupture or even explode, causing personal casualties almost every...
