Description

The The present invention relates to an apparatus and a method for influencing the foam behavior of liquids, in particular carbon dioxide-containing beverages during "Gushing" (especially of Sparkling wine and beer).

Lots carbonated drinks, such as sparkling wine and beer, but also corresponding mixed drinks tend to a violent effervescence, conditioned through an initial delayed, but then explosive release of carbon dioxide in combination with strongly flowing outflow of the beverages from their containers.

It is known that once over or over-foamed carbon dioxide-containing drinks no second time to foam more. So far applied methods, such as the over-carbonization followed by abrupt Relief, are elaborate and for a number of drinks not allowed. They lead about that in addition to strong flavor and taste losses.

The The object of the present invention is a device and to provide a method with which under regulated overpressure easy and without noticeable quality losses within the shortest possible time Time an improvement of the foam behavior of liquids achievable and thus averting the Gushing phenomenon possible is.

The solution The object described above results from the characterizing Part of the claims 1 and 3. Embodiments are in the subclaims described.

The The invention is based above all on the idea that those responsible for overfoaming Ingredients of the above drinks in their composition and concentration influenced by an enrichment in the foam phase are. According to the invention is therefore proposed, the finished carbon dioxide-containing beverage by static and dynamic pressure differences in a nozzle-like Reactor for foaming to bring that up for responsible for the exuberance Substances with the releasing carbon dioxide in the foam phase transported and enriched there to be separated below to be able to.

Surprisingly was found in the experiments with the described apparatus that the liquid Phase of the drinks not treated more explosively ebullient, the separated and liquefied Foam phase, however, very. in principle it was found that the sensory quality of the treated drinks was not suffers and the foam behavior is significantly improved.

The inventive method and the device for influencing the foaming behavior of the above said carbonated beverages provides that the beverage from a pressure vessel over the Reactor, for reasons of hygiene and not to negatively influence the flavor and taste of the drinks, made of food-neutral material, preferably stainless steel should, is directed. After passing through the liquid through the reactor, the different phases of the drink in one special foam-reducing pump separately and separate containers under overpressure fed. The foaming of the drink necessary pressure differences and the treatment section in the reactor can ever after drink be adjusted individually with this equipment.

The inventive device consists essentially of two parts. First, a reactor is provided, the according to the principle a nozzle works with coupled expansion vessel. Of Further, the reactor is coupled with a foam reducing pump. It is understood that this apparatus with various manometers and sight glasses for Control and adjustment of the foam behavior must be equipped depending on the drinks.

By suitable dimensioning of the aggregates and adjustment of the pressure differences is it thus possible Carbonated beverages controlled and sufficiently frothed on-line as well as the various Phases to separate satisfactorily.

The device for influencing the foam behavior of liquids, in particular carbon dioxide-containing beverages consists essentially of a nozzle reactor ( 3 ), a foam-reducing pump ( 6 ), a nozzle chamber inlet valve ( 2 ) at the reactor inlet, a foam exit valve ( 2 B ) at the foam exit ( 5 ) with foam exit sight glass ( 4b ) in the foam line and manometer on the foam catcher and a liquid outlet valve ( 2c ) at the liquid keitsausgang ( 8th ) with liquid exit sight glass ( 4c ) and upstream liquid outlet pressure gauge ( 7a ) in the liquid line.

The process to be used according to the proposal proceeds in such a way that the liquid is pumped through a reactor which operates according to the principle of a coupled expansion vessel and which is coupled to a foam-reducing pump, then foamed and separated into different phases in which, at the end of the reactor, the foam is conveyed via a branch knee ( 9 ) and the remaining liquid is supplied via a further tube to the storage container.
