METHOD OF PREPARING A POWDER MIXTURE

摘要

The cake mixture is prepared by pouring a liquid. The powder mixture comprises a base powder and a fat with a low melting point. This fat is introduced cold, into a mixing tank (1) in which it is transformed into pieces which are mixed with the base powder, still cold. The method is carried out with the aid of an extruder (2) provided with an extrusion grid (9), the apertures of which are determined in order to reduce the heating of the fat through the grid (9).
