International technology group ANDRITZ has launched a new generation of
small-scale spray dryers designed to help customers bridge the gap between laboratory trials and
industrial-scale operation. The modular portfolio supports product development, process optimization,
scale-up from pilot trials to industrial validation, as well as small-scale production.
The ANDRITZ Dedert small-scale spray dryer range comprises six models with water evaporation
capacities from 5 to 250 kg/hr, enabling small-scale production and process verification across
multiple sectors. Systems are offered in standard execution with single-stage or multi-stage
configurations, including the option to integrate a fluid bed to enhance powder properties and optimize
energy use.
Each unit features a modular, skid-mounted, plug-and-play design intended to shorten installation
time. The design places safety and hygiene at the forefront and complies with internationally
recognized fire-protection, safety, and hygienic manufacturing standards. Typical application areas
include food, dairy, nutraceuticals, and chemicals.
With increasing pressure to validate formulations quickly and navigate frequent product changes,
operators benefit from a flexible R&D and small-scale plant that mirrors industrial conditions. The
modular design enables rapid adaptation to new recipes and process parameters, allowing teams to
run controlled tests, troubleshoot drying behavior, and generate reliable scale-up data without tying up
full-scale production lines. This reduces development loops, enhances process predictability, and
helps ensure consistent powder quality.
“Our objective is to provide a clear pathway from pilot trial to validated operational conditions”, said
Suresh Sundararaj, Global Spray Dryer Technology Manager at ANDRITZ Dedert. “These systems
support data-driven decisions by combining modular configurations with proven standards in safety and hygiene.
