Most people are familiar with the production of milk powder by spray drying. But when it comes to nutraceuticals, the requirements go far beyond simple drying. Here, also the precise control of particle size, structure, and functionality matters – raising the question of which technologies are best suited to meet these more demanding applications.

The transformation of liquid formulations into stable, free-flowing powders is a critical operation in nutraceutical manufacturing. Technologies such as spray drying and spray granulation in a fluidised bed are widely used to achieve this goal. The choice of technology depends on the particle characteristics required for the specific application.
