Spray Dryers & Encapsulators

Spray drying is a commonly used method of drying in various industries, such as pharma, material sciences, chemistry, food, feed and beverages. It allows working with aqueous media, acids, organic solvents or mixtures of aqueous and organic solvents in a safe way. During the drying process the liquid media is dispersed into fine droplets which are subsequently dried in a cylinder using a heated gas flow. The reachable particle size depends on the technology of dispersion. For pilot and production scale spray drying, we offer customized solutions from Riera Nadeu.

Riera Nadeu Spray Dryers work in a continuous way by atomizing slurries in a vertical drying tower. This solution is ideal for thermosensitive products requiring a soft and longtime drying to produce a dry powder made of fine particles and for products that could also be encapsulated. RINA Spray Dryers are customized to the customer’s specifications, considering the process requirement or general arrangement of the production plant.
Riera Nadeu offers special configurations for the drying of corrosive products with some drying lines made of Hastelloy®. Also, for toxic products, some drying lines are fitted with a CIP system, in compliance with OEB4 requirements. Moreover, RINA Spray Dryers can work in closed loop circuits with nitrogen, if required.
Riera Nadeu offers solutions for the most demanding industries, including biotechnology, pharmaceuticals and food. More information
