Spray Dryer

Spray drying is a one-step continuous unit operation that employs liquid atomization to produce droplets that are dried to individual particles when moved in a hot gaseous drying medium. A spray dryer consists of a feed pump, atomizer, air heater, air dispenser, drying chamber, and systems for exhaust air cleaning and powder recovery/separator. by a team of expert engineers with rich industry experience.

The three stages that occur in a spray dryer before drying is accomplished include: 1. Atomization 2. Spray-air mixing and moisture evaporation. 3. Dry product separation from the exit air. The nature of the final product obtained after drying in a spray dryer depends on;

Application:

• Spray dryer is used in drying pharmaceuticals like penicillin, blood products, enzymes, vaccines, etc.
• It is used in the production of excipients and co-processed excipients with increased flowability, compatibility, and tablet disintegration.
• To improve drug compressibility and reduce capping tendencies in crystals.
• It is equally used in the preparation of matrix microcapsule containing drug substances and a biodegradable polymer in order to obtain controlled drug release formulation.
• It is employed in enhancing solubility and dissolution rates of poorly soluble drugs by formation of pharmaceutical complexes or via the development of solid dispersion thus increasing bioavailability.
