Small Scale Spray Dryers

SD2000

The small scale spray dryer type SD2000 has a chamber diameter of 2000 mm. This small scale spray dryer works perfectly for R&D, universities and companies.

The small scale spray dryer type SD2000 has a chamber diameter of 2000 mm. The SD2000 is available as a standard plant and features a range of optional items and modules, thus enabling customisation to match individual requirements.

The SD2000 is available in two configurations – a single stage and a multi stage configuration.

SD2000 Single Stage

In an SD2000 spray dryer with a 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 the production of single spherical particles.

SD2000 Multi Stage

In an SD2000 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, situated below the cyclone, blows back the fines to the wet atomisation zone at the top of the drying chamber. The multi stage configuration enables the production of dust-free agglomerated particles.

State-of-the-art design

The SD2000 is produced in sanitary design following the GMP guidelines and includes state-of-the-art solutions regarding safety and cleaning. Furthermore, the SD2000 is equipped with a sophisticated PLC based control system. All parts in contact with the product are made of stainless steel and all elastomers are food grade approved. The SD2000 is skid-mounted, FAT-tested and pre-wired which minimise the installation time and the costs.

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.

Small but effective

All plants are skid-mounted, FAT-tested, and pre-wired which minimise the installation time and the costs.
