The Spiral Flash Dryer is a highly efficient convective dryer which combines the advantages of a flash dryer with those of a fluidised bed. Short residence times combined with powerful turbulent flows ensure gentle product treatment, in addition to high evaporation speeds. Furthermore, it is possible to build exceptionally compact units thanks to the fast heat and mass transfer. The Spiral Flash Dryer has further outstanding specifications: total absence of moving parts, easy maintenance, precise process control and good thermal efficiency with heterogeneous products as well.
Processes: Drying, cooling or roasting.
Applications: Bulk products, powders, fibres, minerals, filter cakes, sticky products, etc ...
Advantages: Gentle product treatment, total absence of moving parts, small volume, easy to maintain, precise process control. Tight thermal efficiency even with very heterogeneous products.
