Abstract
The invention relates to a method for spray drying perishable liquid products such as milk products. The exhaust gas from the spray dryer is passed through a gas scrubber in which at least part of the liquid product to be dried is used as washing liquid before spraying it into the spray drying chamber of the spray dryer. Prior to passing it into the gas scrubber the washing liquid is heated to a pasteurizing temperature by suitable heating means. These heating means may, for example, be adapted to inject hot steam into the flow of washing liquid, or the heating means may be in the form of an evaporator connected to the spray dryer at the upstream side thereof.
