Abstract (en)

[origin: CH694267A5] Untreated flour and air are introduced into a pulverizing mill (12). The impact velocity is at least 150 m/s. During the treatment, the mean residence time of the particles in the mill, is at least 0.003 s/kg per cm2> of rotor surface. An independent claim is included for corresponding equipment. Preferred Features: Variant processing conditions, based on the foregoing, are described. The flour temperature immediately following the mill is preferably 40-60[deg]C, and 70[deg]C at most. Residence time is controlled by the air quantities supplied to the flour before entry into the mill and following its exit from the mill. It is controlled by changing the rotary speed. The impact mill is a pinned disc mill.
