Abstract
Abstract Skim milk powder and fats are separately propelled upwardly from a central bottom inlet substantially vertically by a current of air whose moisture, temperature and velocity are controlled and thence outwardly and downwardly in a surrounding airstream of lesser velocity. The milk powder and fats are brought into intimate contact while in said airstreams whereby a granular, water-soluble product suitable for livestock forage is obtained.
