Method of preparing a powdered product, particularly powdered milk

摘要

Disclosed is 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, in which, during a first step the product in the liquid state is transformed into a product in the viscous state, wherein there are carried out at least one overrun step and at least one product-drying step comprising at least a first thermomechanical treatment step with at least one thermomechanical treatment machine into which the viscous state product and a determined amount of powdered product from the same family as the liquid state product are injected simultaneously, the treatment machine being configured to mix the viscous state product and the powdered product so as to produce solidified particles of product upon contact with the ambient air.
