FERMENTATION METHOD AND APPARATUS

摘要

The present invention relates to a method for the fermentation of a mixture, particularly in the fermentation of musts and/or grape for wine production, to an apparatus for performing said fermentation, in addition to the maceration, aging and storage of wines, as well as to the use of said apparatus in the maceration, fermentation, aging and storage of grape, must and/or wine, particularly in the fermentation of musts for wine production.

主权项

1. A method for the fermentation of a fermentable mixture, said fermentable mixture comprising a liquid part and a solid part, comprising:
(a) providing at least a tank (1) suitable for containing the fermentable mixture comprising means (2) for fermentation gas extraction located in the upper part of the tank suitable for containing the fermentable mixture (1), means (3) for fermentation gas compression and means (4) for large fermentation gas bubble formation located in the lower part of tank (1), wherein the means (4) comprise a bubble formation element (8) and a non-return valve (9); (b) providing at least a tank (5) for fermentation gas storage; (c) introducing the fermentable mixture into the tank suitable for containing the fermentable mixture (1); (d) extracting the fermentation gas generated during the fermentation of the fermentable mixture through the means (2) for fermentation gas extraction, (e) compressing the fermentation gas extracted in step (d); (f) accumulating the fermentation gas compressed in step (e) in the tank for fermentation gas storage (5); and (g) introducing the fermentation gas of the tank for fermentation gas storage (5) into the tank suitable for containing the fermentable mixture (1) through the means for large fermentation gas bubble formation (4) located in the lower part of the tank suitable for containing the fermentable mixture (1);wherein the large fermentation gas bubble has a volume between 5% and 40% of the volume of the tank suitable for containing the fermentable mixture (1).
