Disclosed is a process in which a viscous initial product having both a temperature of between 5° C. and 70° C. and a viscosity greater than 100 mPa.Math.s is provided, —by way of a pump provided upstream of at least one aerator, the viscous initial product is transferred as it is to the at least one aerator in which the viscous initial product is mixed with a gas, injected into the aerator, so as to obtain a liquid foam continuously exiting the aerator, and—the liquid foam continuously exiting the at least one aerator is continuously pushed into the inlet of a treatment device which continuously divides and then dries this liquid foam so as to obtain a powdered porous product which has a solids content greater than 90%.
