Whether you’re conducting R&D or interested in small-scale or industrial production, you can depend on GEA Niro. We offer powder engineering solutions and proof of concept through laboratory and pilot plant testing, unmatched scale-up experience and global project execution according to your specifications.

With data gained from more than 70 years of experience and a reference list of more than 4.000 pilot plants across the globe, we’re equipped to engineer the properties you want into your products- and the process needed to produce them.

Our series of small-scale dryers goes from the popular MOBILE MINOR™, with a water evaporative capacity from below 1 kg/h, to the VSD-50, with a capacity of up to 450 kg/h, depending upon the feed properties and temperature profile.

Since drying characteristics and product specification vary from product to product, there is no one process or dryer design suitable for all applications. By offering a full range of processes and designs, GEA Niro impartially selects the most suitable equipment.
