A process for the preparation of an animal feed supplement based on fermentation broth is disclosed, wherein the supplement contains wholly or predominantly a fermentation product and the other constituents of the fermentation broth, which is characterised in that the fermentation broth is granulated, compacted and dried in a fluidised bed in one step whilst a sufficient amount of energy to obtain a desired particle diameter and a desired bulk density is introduced into the fluidised bed by mechanical device in addition to the energy required to produce the fluidised bed. As a result of this, it is possible, inter alia, to prepare continuously, in a single process step, granules conforming to specification of additives such as lysine, threonine or tryptophan using, in particular, raw fermentation broths as starting substance.

A method for the production of spherical granulated materials from powdered solids and the granulated materials produced by it are disclosed. The method is characterized in that the powdered solids are moistened, possibly together with the usual binders, flow agents and plasticizers for the compression of solids, by the addition of a corresponding quantity of liquid and mixing smoothly in a mixer; they are then compressed with a ring collar mill into cylindrical agglomerate and then rounded in a rounding unit with wrinkle washer. The granulated solids thus produced have a very narrow particle size distribution and are distinguished by good flowability and good dispersability, depending on process controls.
