The effect of temperature and dry matter content on the viscosity of malt concentrate designed for spray-drying was studied. The viscosity coefficient values were determined by the viscosity meter Haake RS 50. Spray drying was carried out in drier Anhydro Lab 1. It was stated, that the decreasing of viscosity coefficient (η) of malt concentrate, caused by the raising of temperature (t), could be described by the exponential function η = a+b•exp(-t/c). Simultaneously the drying process was accompanied by the proportional rate of evaporation and yield of powder production increase with the decrease of viscosity. It has also been found, that the viscosity of malt concentrate increases with the increasing of dry matter content (D), according to exponential function η = a•exp(b•D+c), while the rate of evaporation decreases and yield of powder production increases. For the intensification of drying process yield under industrial conditions it was suggested to transport the malt concentrate directly from the evaporator to spray-drier.
