ABSTRACT:
A method of prilling or spray drying comprising calculating and controlling the viscosity of a shear-thinnable fluid stream at a particle-forming section of a dispersion device. The method comprises measuring the static head of fluid in the dispersion device, providing a pressurized blanket of inert gas over the fluid, mechanically agitating the fluid in the dispersion device, calculating the viscosity at the particle-forming section and controlling the viscosity by adjusting the speed of mechanical agitation.
