Application: Semi-industrial-scale evaluation of FSD™ drying feasibility and test of the unit for clients interested in small-scale production and R&D applications.
Capacity: The evaporative capacity is 5-40 kg/h and the minimum amount of feed required is about 100 kg.
Specification: The chamber has a 1.6 m diameter with a 0.86 m cylindrical height and a 40 degree cone. The 600 kg/h of drying air is heated electrically and has a maximum inlet temperature of 350 °C.
Feed is supplied by a Mono pump and is atomized by either a co-current two-fluid nozzle or a pressure nozzle.
The plant has two different drying modes; the first is traditional spray drying, with product recovery from either a bag filter or a cyclone. The second mode is the Fluidised Spray Dryer with an Integrated Fluid (IF) bed under the chamber. The fluid bed has an inner section for agglomeration and two outer sections for controlling the residual water content and for cooling of the powder. In this second mode, the plant can clean exhaust gas by either internal bag filters, a traditional external bag filter or a cyclone.
The combination of fluidization and spray drying enables particle size and structure to be easily controlled and is, therefore, often used for agglomerate or granulate production. Sticky products can be dried successfully, and the concept is ideal for drying heat sensitive products, and improved aroma retention is accomplished.
In addition to the FSD-IF™-6.3 Two-mode Fluidised Spray Dryer, the Test Center also offers an FSD MINOR™. Both are ideal for small-scale production and product development.
