Abstract
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 (E1) 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 (E2, E4) and at least one product-drying step (E3, E6) comprising at least a first step (E3) 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.
