Microbial Additives
In the first step of the fluidized bed process, so-called pellets are put into the process vessel. By applying a constant process air flow, a strong mixing (fluidised bed) of the pellets in the process vessel is generated. Subsequently, the liquid bacteria concentrate is fed into the container via spray lances, dispersed into very fine droplets and continuously applied to the pellets. At the same time, drying takes place under mild conditions (34-38°C). In a further step, the protective layer is applied on the pellets in the same way. Finally, in the clean room the finished end product is filled into bags (max. 25 kg) or into big bags (500 kg).
