The SD900 is targeted for R&D work as well as experimental scale production. It is available as a standard plant and features a range of optional items and modules, thus enabling customisation to match individual requirements.
The SD900 is available in two configurations – a single-stage and a multistage configuration.
SD900 Single Stage
In an SD900 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.
SD900 Multi-Stage
In an SD900 spray dryer with a 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.
Designed with a focus on efficiency and safety
The SD900 is produced in sanitary design following the GMP guidelines and includes state-of-the-art solutions regarding safety and cleaning. Furthermore, the SD900 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
Every SD900 that leaves the SiccaDania factory has been FAT-tested and pre-wired, minimising installation time and costs. The SD900 is skid-mounted for easy transport and installation.
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 minimises the installation time and the costs.
