Disclosed is a process in which a viscous initial product having both a temperature of between 5&#xb0; C. and 70&#xb0; C. and a viscosity greater than 100 mPa&#xb7;s is provided, &#x2014;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&#x2014;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%.

Process and facility for producing a powdered porous product

The present invention relates to a method for producing a powdered porous product from at least one starting powdery and/or viscous product, characterised in that it comprises the continuous following steps without exposing the product to open air: a) preparing the starting product in order to make it viscous; b) in a thermo-mechanical machine () for continuously realising transport and/or mixing functions of viscous products or dry-material rich products, lowering the viscosity of the viscous product without changing its dry-material content, by intimate mixing with a gas injected into the processing machine () and simultaneously initiating the porosity in the viscous product; c) continuously with the processing machine (), statically or dynamically intensifying the intimate mixture of the viscous product with a gas in order to obtain an aerated and porous mass; and d), dividing said mass in order to obtain aerated and porous particles.
