Niro spray dryers

How does the GEA Niro spray dryer work?

Niro manufactures high-quality dryers that enable manufacturers to generate dry powder from a slurry. The drying method involves exposing the slurry to hot gas that separates the liquid to produce a dry powder. It effectively dries thermally-sensitive materials and produces fine and consistent particle sizes. Niro spray dryers use atomisers or spray nozzles to disperse the liquid to drop-size spray for easy drying. When the process commences, the air in the drying medium is heated. When the drop-sized sprays are exposed to the hot air, moisture evaporates, and the dry products accumulate at the bottom of the chamber. While the process is effective, single-effect spray dryers often produce dust and have poor flow due to inconsistent particle sizes. Modern spray dryers use two drying steps to minimise dust. The first drying step is the single effect process, and then the liquid is further dried in the static bed at the bottom of the chamber. The chamber provides a humid environment that allows small particles to clump together and generate uniform sizes.

What are the applications of Niro dryers?

Niro spray dryers provide multiple benefits, including superior product quality and controlled properties. For instance, you can adjust the drying process to get finer powder particles. You also dry your products at low atmospheric pressure and temperature. Some of the applications of Niro spray dryers for sale at Foeth include drying blood products, enzymes, and penicillin in pharmaceutical industries. You can also use them to produce tablets and improve drug compressibility or capping tendencies in crystals. Since the nozzles can break down the liquids into small droplets, it enhances solubility in drugs and improves their bioavailability. Some companies use spray dryers to produce powder aerosols and other materials. Spray dryers are also useful in chemical industries to produce resin, catalysts, and amino acids.
