GEA Niro

GEA Niro is a Danish company that has been a part of the German GEA Group since 1993. GEA Niro specializes in the development, design and engineering of liquid and powder processing equipment for the manufacture of products in powder, granular or agglomerate form. The GEA Group has specialised in process engineering, process equipment and plant engineering.GEA Niro has supplied technology for many companies in the world for their production of dairy and food products, chemicals and pharmaceuticals. Some of these products are manufactured in a single plant, others in a fully engineered process line designed and installed by Niro in collaboration with leading suppliers of auxiliary equipment.

Company history

A/S Niro Atomizer was founded in 1933 by Johan Ernst Nyrop and specialised in industrial drying, with spray drying, freeze drying, and fluid bed processing as core technologies. In the 1990’s Niro dropped "Atomizer" from the company name and in 1993, the Niro Group was acquired by the German GEA Group and began to co-operate closely with other GEA companies specializing in process technology and engineering. A growing importance of controlling feed quality prior to drying brought Niro into the concentration business and falling film evaporators became part of the scope of supply, primarily within the dairy industry. This involvement in pre-treatment has since grown to include extraction and membrane filtration. The start of this period saw the two-stage drying concept introduced to the dairy industry. Spray drying technology was also applied to air pollution control in 1978. In 1989 the need to further develop particulate processing techniques led to Niro upgrading its fluid bed technology and introducing new equipment for blending, coating, pelletising, and de-dusting (to produce powdered, agglomerated or granular products of specific properties). During the 1990’s Niro formed the Niro Pharma Systems business unit in order to strengthen the presence of the Powder Technology Division in the pharmaceutical market. In 2002, Niro A/S acquired the activities of the Atlas Food Division from Atlas-Store Denmark A/S, specializing in the design and supply of freeze drying systems for food applications and vacuum systems for deodorizing edible oil.
