Abstract
For continuous production of dealcoholized beverages, a substrate consisting of fruit or berry juice, grape juice or beer wort is first preclarified in a microfiltration device (2) and sterilized and then fermented by immobilized microorganisms in the fluid bed process in a tower fermenter (3). Support particles (12), which are kept in suspension in tower fermenter (3) and to which the microorganisms are bonded, guarantee an effective biomass retention. After fermentation in tower fermenter (3), the raw juice is freed of alcohol in a dealcoholization device (24) and then clarified in an ultrafiltration or microfiltration device (27). The process taking place in a continuous product line makes possible an especially economical and productive operation of the unit.
