Varcogroup spray dryers are designed to dry liquids to powder by means of an atomizer in a high-efficient range. This very gentle drying is mainly used to dry heat sensitive products.
The atomizer forms the liquid into small droplets before spraying them into a hot air stream, where the major part of the water evaporates in a few seconds. At the end, the dried powder will be separated from the air by a cyclone and/or a filter system. Downstream the dryer can be equipped with fluid beds, coolers and agglomerators, to further condition the powder prior to the packaging unit.
