New Recovery System for Milk Powder in Spray Drying Process

Abstract

The size reduction of milk powder that occurs in a cyclone by the spray drying process increases its free-fat content and degrades its reconstitution properties and keeping quality. A new recovery system consisting of a virtual impactor and cyclones was developed to prevent the size reduction of milk powder. The impactor was effective in preventing size reduction and reduced the increase of free-fat content of milk powder. © 1991, The Society of Chemical Engineers, Japan. All rights reserved.
