Abstract: Preparation of a fermented sludge for use as an animal feed additive which contains a fermentation product, comprises granulation, compaction and drying of the sludge in a fluidised bed, at the same time as introducing extra mechanical energy above that needed to fluidise the bed particles, in order to achieve the desired additive particle size and bulk weight.
