A process for producing defoamers

The invention relates to a method for producing defoamers, wherein the defoamer is a silicone-containing material is mixed. The invention is based on the object to develop a process for producing usable in detergents and cleaning agents or foaming liquids defoamers, a highly effective, homogeneous and very readily dispersible end product with in a simple and inexpensive method of production with good storage properties. According to the invention the production of usable in detergents and cleaning agents defoamers is effected by continuously / emulsion a homogeneous melt suspension consisting of molten urea, 1-10% of solid starch and 5-25% silicone oil, is jetted into a made of material private Good fluidized bed wherein while supplying cold air supply, a defined solidification and granulation of the molten suspension / emulsion, preferably in a fluidised bed at fluidised bed temperatures of 30-60 ° C to form homogeneous granules with a defined particle size of preferably 0.2-2.0 mm and a bulk density of occurs greater than 600 kg / m
