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.

Method and equipment for the continuous production of a porous powdered product

The invention relates to a method for the continuous production of a powdered product from a product in the liquid state in the form of a solution-, suspension- or emulsion-type mixture in an aqueous medium. According to the invention, during the first step (E) of the method, the product in the liquid state is transformed into a product in the viscous state. The invention is characterised in that it includes at least one overrun step (E, E) and at least one product-drying step (E, E) comprising at least a first step (E) involving thermomechanical treatment with at last one thermomechanical treatment machine into which the viscous state product and a determined amount of powered product from the same family as the liquid state product are injected simultaneously. The treatment machine is configured to mix the viscous state product and the powdered product such as to produce solidified particles of the product upon contact with the ambient air.
