Small Scale Spray Dryers

SD3150

The small scale spray dryer type SD3150 is the largest of the SiccaDania small scale spray dryers with a chamber diameter of 3150 mm.

The SD3150 is available as a standard plant and features a range of optional items and modules, thus enabling customisation to match individual requirements.

 

The SD3150 is available in two configurations – a single stage and a multi stage configuration.

SD3150 Single Stage

In an SD3150 spray dryer with single stage configuration, the feed product and the process air are introduced into the top of the drying chamber. Here an instant contact between the atomised feed product and the heated process air takes place and the water evaporates from each droplet. All air and powder are led through the drying chamber to the cyclone for efficient powder separation. The single stage configuration enables production of single spherical particles.

SD3150 Multi Stage

In an SD3150 spray dryer with multi stage configuration, the feed product and the process air are introduced into the top of the drying chamber. Here an instant contact between the atomised feed product and the heated process air takes place and the water evaporates from each droplet. For further drying of the powder, an Internal Fluid Bed (IFB) with a separate air supply system is installed below the drying chamber. From this IFB, the powder is discharged whereas the fines are led to the cyclone together with the drying air. For optimal product utilisation, a fines return system blows back the fines to the wet atomisation zone in the top of the drying chamber. The multi stage configuration enables production of dust-free agglomerated particles.

State-of-the-art design

The SD3150 is produced in sanitary design following the GMP guidelines and includes state-of-the-art solutions regarding safety and cleaning. Furthermore, the SD3150 is equipped with a sophisticated PLC based control system. All parts in contact with product are made of stainless steel and all elastomers are food grade approved. Due to the size of the SD3150 spray dryer, it is foreseen to be installed in an existing building layout.

The spray drying process is scalable and the SiccaDania small scale spray dryers are available in many flexible configurations enabling process simulations of larger industrial size spray dryers
