Abstract A new multinozzle system with 13 nozzles for the encapsulation and immobilisation of micro-organisms, enzymes or cells is presented. Based on the laminar jet break-up, monodisperse beads of calcium alginate are produced under sterile and reproducible conditions in the range of 0.2¨C1 mm. An in situ cleaning of the nozzles is implemented in order to guarantee several batch process cycles and a productivity of up to 5000 ml h1. Beads were analysed and showing that the relative difference of the mean diameter of the different nozzles was less than 0.3% and the coefficient of variance (CV) of the beads were from 1.94 to 2.93 mm which means that there are less than 4% of error droplets with double volume produced in the collective.
