ABSTRACT:
Milk or similar liquids are spray dried using a rotary atomizer wheel whereby such a temperature is imparted to the liquid that a violent release of gas and vapor from the liquid takes place in the atomizer wheel, which gas and vapor are removed before the atomization of the liquid. By these means a powder having at high bulk density and a low content of occluded air is obtained. A special atomizer wheel, having two sets of ejection apertures and two intercommunicating supply compartments makes it possible to eject released gas and vapor through one set of apertures and liquid through the other set, whereby reintroduction in the liquid of the released air is prevented. Also an atomizer wheel of this type is provided wherein the two supply compartments are steam-swept.
