The most economic method for producing soluble coffee is spray drying, which results in free-flowing and agglomerated/granulated powders. Thanks to an extremely high level of control, our customers can manufacture products meeting the demands of their individual markets. The design of the spray dryer depends upon the desired powder properties, e.g. moisture content, particle size, and bulk density.
