Description

A kind of refrigerated fresh-keeping draft beer keg

technical field

The utility model relates to a draft beer barrel, in particular to a draft beer barrel capable of cooling and keeping fresh.

Background technique

With the advancement of science and technology and the continuous improvement of people's living standards, people's requirements for quality of life are also getting higher and higher. However, the word temperature does not surround people's lives all the time. Refrigerators, air conditioners, supermarket freezers, cold storage, medical refrigeration, military aerospace and many other aspects use low-temperature environments. Therefore, more and more low-temperature environments affect our lives and change our lives more and more.

Draft beer is a high-quality wine that is pure natural, has no pigment, no preservatives, no sugar, and no flavor. It is extremely nutritious. Draft beer is to inject the highest quality sake directly into a fully enclosed draft beer barrel, and a refrigerated truck must be used during transportation. Before drinking, use the draft beer machine to charge carbon dioxide, and use the draft beer machine to control the wine at 3-8°C. When drinking, it is directly poured from the draft beer machine into the beer glass, avoiding the contact between beer and air, and making the beer fresher, purer and thicker. The richer foam is more refreshing when drinking, and the aftertaste is endless. Draft beer has high requirements on the transportation and storage environment, so it must be drunk in a short period of time, and the shelf life is only 7 days. The insulation of draft beer kegs for storing draft beer is insulated by the insulation cotton between the inner and outer shells. If the cold supply is not available during transportation, the low temperature environment required by draft beer cannot be guaranteed, which will inevitably affect its freshness and taste. , leading to a sharp drop in sales, a reduction in customers, and a loss of production efficiency for manufacturers. Therefore, it is very important to ensure low temperature during draft beer production and transportation to sales and drinking.
