METHOD FOR THE PRODUCTION OF EFFERVESCENT GRANULES IN A VACUUM

摘要

The invention relates to a method for producing effervescent granules, in which the reaction partners edible, organic acid components and alkaline effervescent components separating carbon dioxide are reacted with each other in a vacuum under the effect of gas in a container that can be evacuated. Said container is evacuated to a first vacuum value within a vacuum range of 200-900 mbar, whereupon the pressure inside the container is increased to a second vacuum value as a result of the gases produced during the reaction. Said steps are cyclically repeated while the reaction continues. A maximum number of cycles, a maximum reaction time, and, optionally, a maximum load for the stirring apparatus are defined before the reaction begins, and the reaction is terminated after reaching the first of said maximums. In an alternative embodiment, the invention also relates to a method for improving the shelf life of effervescent granules by means of a treatment with carbon dioxide during and/or following the production of the effervescent granules, and effervescent particles treated in this manner.
