Abstract: A device for extracting aroma substances from vegetable aroma carriers into a brewing liquid, in particular into beer, includes a fluidized bed extractor accommodating a suspension bed including the brewing liquid and solid particles contained in aroma carriers. The fluidized bed extractor has at least an inlet and an outlet for the brewing liquid. A feed pump pumps the brewing liquid from the inlet through the fluidized bed extractor to the outlet. A feeding speed of the feed pump is set to a value at which an average vertical feeding speed of the brewing liquid in the fluidized bed extractor is lower than an average vertical sedimentation speed of the solid particles in the fluidized bed extractor.

Abstract: The present invention relates to a method for an accelerated fermentation in a fermentation tank 2 with at least a tank cone 2a and a connection flange 4, in particular for beer production. The method comprises the steps: a) sucking in of fermentation fluid M1 from the tank 2 via a first circulation pipe 40 by means of a circulation pump 30; b) inducing of the drive fluid M1 that is now pumped by the circulation pump 30 via a second circulation pipe 50 in a mixing member 10 that is arranged within the tank cone 2a at a height L of 350 mm-1800 mm between the bottom edge of the connection flange 4 and the bottom edge of the mixing member 10; and c) generating of a jet directed upwards and exiting through an outlet opening 18 of the mixing member 10, so that the yeast cells stay for a longer time in suspension in the tank 2 by means of an in such a way improved convective current. The invention relates moreover to a corresponding device.
