Spray Drying Process Solutions

Spray drying has become the most important technique for dehydrating fluid foods such as milk, coffee and egg powders, and is used extensively in the pharmaceutical and chemical industries. Atomization is of particular interest in the metals industry for generating fine powders. Malvern Process Systems (MALPS) continuous particle size analyzers have been used to:

Optimize atomizer set up
Allow spray dryer control
Tighten product specifications
