Among the integrated technologies of Nol-Tec Europe systems, provided under the brand NTE Process, the Spray Drying is a very important process that allows to obtain high quality engineered powders for various industries (Food, Pharmaceutical, Ceramic, Environment, exc). Nol-Tec Europe combines its own experience in powder Material Handling with the powder production thanks to the partnership with the Japanese company Ohkawara Kakokhi, worldwide leader in Spray Dryer production with patented technologies. The Spray Drying technologies allow to atomize slurry and liquid compounds with different degree of viscosity, producing fine powders with precise particle sizes, thanks to patented atomizing nozzles. Furthermore, the obtained powders have a high degree of fluidity and solubility, thanks to the perfect distribution of the shape and of the particle size that is obtained by the atomizing process. Nol-Tec Europe offers solutions with different approaches, from turnkey plants to retrofitting of existing systems, and also closed loop laboratory spray dryers.
Spray & Dry Nol-Tec technology is the most dependable process for producing dry powders from any type of liquid solution or slurry feed. The feed is dispersed into a mist of fine droplets either by means of a rotary disc atomizer or a spray nozzle.
This spray mist is distributed into a cylindrical drying chamber along with a stream of hot gas and typically blown dry within a second split. After remaining in the chamber for a certain residence time - for further reduction of the residual moisture - the generated dry powders are separated from the gas flow either directly at the base point of the chamber or via downstream aero cyclones and bag filters.

Nol-Tec Europe has a Test Plant at its Research Centre in Pessano con Bornago (Italy) where spray drying test can also be performed for the customers, in order to optimize the engineering process both during quotation or job step and to test innovative products or processes together with the customer. Our potential customer can research and design new products or verify how NTE Process Spray Dryer performance can be improved. Furthermore, the test can prevent any critical issue that can occur during the plant start up, shortening the testing time. A further test analysis provides relevant information for the design of the suitable engineering and the best settings for the performance control during the plant start up.
