Description

Aeration pressure-maintaining fresh-preserving pure draught beer cask

The utility model relates to a kind of liquid container bucket, and this drum is mainly used in splendid attire, accumulating, sale draft beer or other various soft drinks.

At present, known draft beer bucket generally all by behind stainless steel sheet punching press, the stretch forming, is made through welding again, and the staving outside does not have the heat insulation protecting layer, general designation light bucket.Beer Production factory transports with refrigerated truck after being filled to draft beer (being commonly called as beer on draft) in this fat, is supplied to market.Because of draft beer all must be isolated before drinking from being filled to air (invade with anti-oxidation and assorted bacterium cause that wine liquid is rotten), also must use the expensive wine selling machine of outfit specially can realize that anoxybiotic goes out wine, lowers the temperature and fills up carbon dioxide when selling beer.This transportation and sale, go out the configuration of wine mode and corresponding establishment, cause draft beer to drink the occasion scope on the one hand and receive limitation greatly, cause the draft beer integrated cost too high on the other hand, the wine valency is high, cause the bottleneck effect of draft beer production and consumption, controlled the market demand and the sales volume of draft beer.

Know a kind of draft beer bucket again, by plastics inner bag, middle heat-insulation layer, plastic casing, beer filling valve, go out wine valve, air inlet valve etc. and form.This bucket could be realized the beer anaerobic filling and transport that not using special-purpose wine selling machine can go out wine (is not that anoxybiotic goes out wine! ), thereby can effectively reduce the integrated cost of draft beer.But this barrel of beer has two kinds of critical defects:

1. this barrel of beer is because of adapting with cleaning, sterilization, the filling apparatus system of brewery's standard or special complete, can't thoroughly carry out cleaning and sterilizing to fat before irritating wine at every turn, makes the sanitary condition out of reach food hygienic standard of this fat.

2. must open air inlet valve when this barrel of beer goes out wine by in the air admission fat, otherwise beer can be because to go out in the bucket that wine forms negative pressure former thereby do not flow out in the bucket.Enter air in the bucket, beer is once drunk and is tood many or too much for use, and beer can be invaded because of oxidation and assorted bacterium and be made the very fast decline of vinosity in the bucket.

The purpose of this utility model provides a kind of novel draft beer bucket, this barrel of beer:

1. without wine selling machine, lean on interior disposable functional gas that fills of fat and special use to go out the wine valve and go out wine.Use this wine mode that simply goes out, can drink draft beer whenever and wherever possible easily.

2. the metal inner tube outside coats High molecular material heat insulation protecting layer, both can effectively keep the low temperature of beer, and the freshness date that prolongs wine can protect metal inner tube not to be subjected to clashing and breaking again.

3. cleaning, sterilization, filling apparatus system complete and brewery's standard or special complete adapt, and the fat behind cleaning and sterilizing can strictness reach food hygienic standard.

4. realize fully that anaerobic filling and anoxybiotic go out wine, effectively keep the local flavor and the quality of draft beer.

5. with a kind of new mode accumulating, sale draft beer, reduce the integrated cost of draft beer.

The purpose of this utility model is achieved in that

Inflation pressurize reservative fresh beer barrel mainly goes out wine valve etc. by standard (or special-purpose) wine lance wine mouth, stainless steel inner container, High molecular material heat insulation protecting external coating and special use and forms.Stainless steel inner container designs and produces and becomes one and have the pot container that necessarily bears pressure capability, and the actual volume of fat inner bag is bigger than the nominal volume (when nominal volume is exactly actual use, the volume of fat can wine liquid) of fat.Remaining space inside volume behind the inner bag can wine liquid is that the customized design setting is used for the disposable functional gases such as having the certain pressure carbon dioxide that fills.Disposable to fill functional gases such as carbon dioxide be when going out wine the dispatch of wine liquid to be gone out fat for the pressure energy that utilizes gas, reaches the purpose that anoxybiotic goes out wine.The proportionate relationship of fat inner bag actual volume and fat nominal volume is determined according to calculating.Inner bag assembling standard wine lance wine mouth, therefore can with brewery automatically or S. A. cleaning, sterilization, filling apparatus system adapt.Empty bucket is got back to canning line in the brewery, can beer behind cleaning, sterilization.Under this technological condition, the sanitary condition of fat is good, can strictness reach food hygienic standard.Pressing nominal volume during can beer, also wants fill carbon dioxide in the disposable quantity space that wine liquid top is reserved in bucket in bucket.The inflation pressure size is determined only just whole wine liquid dispatch in the bucket to be gone out fat with the disposable functional gases such as carbon dioxide that fill in the bucket when guaranteeing wine as calculated.Special use goes out the top that the wine valve is arranged on fat, links with wine lance wine mouth.Before going out wine, will go out the wine valve and install, and only need rotate special use when going out wine gently and go out wine valve handle and open out the wine valve, wine liquid under the functional gaseous tension effect, promptly flows out from valve port in bucket automatically.Go out the speed of wine speed and go out how much controlling of capacity for liquor by aperture that adjusts the wine valve or switching.

Owing to go out in the wine process not have extremely in the air admission bucket whole, beer can microbiological contamination or oxidation in the bucket; Because the outside of metal inner tube coats the heat insulation protecting layer of excellent heat insulating performance, the beer that can keep effectively irritating in the bucket after drinking is in low-temperature condition in a long time, thereby can prolong the freshness date of draft beer effectively; Because of the carbon dioxide that fills in the bucket has certain pressure, the meltage of carbon dioxide in wine liquid is corresponding bigger, and when going out wine, it is abundant that beer is gone into glass foam, and mouthfeel is better when drinking.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the vertical section structure figure of first embodiment of the utility model.Among the figure: 1. 4. special uses of standard wine mouth 2. standard wine lances 3. Connection Blocks go out wine valve 5. compression indicators 6. stainless steel inner containers 7. High molecular material heat insulation protecting layers 8. safety valve
