Hygienic drying in a vacuum requires many attributes. The innovative spherical dryer design (photo) provides the highest performance, according process control and the latest GMP standards. This company is currently delivering several units for hygienic drying. The spherical dryer in Rosenmund design delivers fast drying, mixing and granulation; is easy to clean; has total product discharge; and short drying time due to its high heat-transfer design. The lower half of the sphere is removeable either by pivoting or dropping. This allows total and full visual and manual access to the process area. The accessibility, cleanability and a fast and residue-free discharge are the most important prerequisites for the production of high-quality products. Effective trouble-free washing and cleaning (WIP/CIP) are required to maintain the systems in order to meet strict hygienic standards. — De Dietrich SAS, Strasbourg, France
