Coating is an important unit operation used to either modify color, give protection, for taste masking or to create a modified release form in pharmaceutical production. GEA is able to offer some novel as well as all typically used coater systems for particles, powders, granules, crystals, pellets and tablets.

— Coating technologies
GEA supplies coater systems for powders, particles, granules, crystals, pellets and tablets, and helps you select the technology that best suits your process.
Coating is an important unit operation that’s used extensively in the pharmaceutical industry for the application of non-functional or functional coats (aesthetic, protective or rate controlling polymer films) and for the deposition of active pharmaceutical ingredients (APIs) onto nonpareils (multi-particulate dosage forms). Applications include taste masking, color modification, physical protection and/or to create modified release forms.
Beyond efficient API layering techniques for multi-particulate systems, the pharmaceutical industry has an inherent need to accurately coat objects that are 3–30 mm in length (the most common size range for single-unit solid dosage forms) with APIs. These include tablets for oral administration and other delivery methods (human implantation, for example). Existing coating methods in this size range have coating speed and accuracy/uniformity limitations, particularly for the deposition of low dose APIs onto single unit tablet dosage forms.
Available technologies include fluid bed coating for smaller particles, such as powders, granules, seeds, crystals, pellets, and small tablets, a multipurpose processor that uses proven fluid bed technology to achieve granulation, drying and pellet coating (or tablet coating) in a single unit and a revolutionary tablet coater that accurately deposits controlled amounts of coating materials on tablets, even if they are hygroscopic or friable.
Whether you are developing a new formulation or scaling an existing one, our specialists help you match coating technology to your dosage form, batch size and regulatory pathway, with trials on your own product at the GEA Pharma Solids Test Centers.
— GEA coater range
Designed to gently and accurately deposit controlled amounts of coating materials onto tablet cores — even if they are hygroscopic or friable — the high-performance GEA coater technology is able to process both small and large quantities of tablets at very high suspension application rates.
The containment performance of the GEA Coater, described as a “new generation” device capable of both continuous and batch film coating, was assessed during three phases of operation and discussed in a peer-reviewed journal
Unter der Prämisse, ein neues Verfahren für ein vollständig formuliertes Beschichtungssystem für magensaftresistente Tabletten zu untersuchen, wurde eine Studie durchgeführt, um die Eignung eines neuartigen halbkontinuierlichen Beschichtungsverfahren für eine rasche Aufbringung einer wässrigen, magensaftresistenten Beschichtung als eine Modell-funktionale Beschichtung zu bewerten.
