DIOSNA Processing plants for laboratory and production Vertical Centrifugal Coater VCC Film Coating of Tablets. Efficient, Accurate, Fast.
VCC. The Future of Coating DIOSNA Vertical Centrifugal Coater VCC gives a new definition of coating technology, leaving behind many of the well-known disadvantages of conventional coaters. The flexible concept of the VCC offers various ways of application and stands for convincing coating results even with products of adverse flow characteristics, special shape or less hardness. High drying performance of the VCC and optimized product flow reduce the process times by more than 50 % not only with organic solvent based but also with watery processes. DIOSNA VCC Vertical Centrifugal Coater increases the efficiency of the coating process reduces process times considerably reduces the thermal and mechanical product stress increases the yield due to less spray losses improves the product handling VCC-75
High quality coatings by an efficient process VCC the efficient way to first-class film coating uniform coating thickness defined outlines, distinct imprinting high process speed time saving > 50 % containment suitable feeding and discharge small installation area requirements easy technology transfer without change in registration (SUPAC listing) Particularly for functional coatings or moisture-sensitive tablets a quick and even coating ensures high quality. Versatile applications with exact coating results from micro tablets to oblong shapes sugar coating, aqueous coating, coating with organic solvents for extremely thin, functional coatings actives coating The VCC Vertical Centrifugal Coater is suitable for most different tablet forms. Conventional round tablets of different sizes, special forms (oblongs, bi-plane tablets) as well as micro tablets are coated with excellent quality.
Shortened process times, optimum coating Uniform and quick spraying DIOSNA uses a specially developed multiple head nozzle. Its single nozzles are installed in a rotation-symmetrical way at a compact distributor head. As the media lines run completely inside the multiple head nozzle, a very clean, GMP-conform installation without freely running hose pipes arises. Because of the high mixing quality the product is only sprayed very shortly during the spraying process, but very often. Compared with traditional coating plants this results in a very homogeneous coating over the whole tablet surface. The coding of single tablets is kept clear even with complicated figures or patterns. This leads to a homogeneous and high-quality appearance of the whole tablet batch. The VCC is a coater which is emptied completely and automatically to the last tablet. Product bowl, lid and spraying nozzle are ideally accessible. By means of the nozzle arm lid and spraying nozzle can be swivelled aside. This allows for comfortable charging and ideal bowl inspection or cleaning.
The VCC Vertical Centrifugal Coater consists of a conical product bowl which lower part is rotating around a vertical axis and an upper conical part. The rotational movement causes a centrifugal acceleration of the tablets which makes the tablets move upwards at the bowl wall. In the static upper bowl area the tablets are decelerated and led back to the centre. The spiral movement caused this way cares for ideal mixing of the tablets without any dead spots. In the centre of the bowl a spraying system is installed which sprays the tablet bed homogeneously with coating medium. Already immediately after absorption of the spray liquid the first drying of the tablet surface is effected by the warm drying air. The air is led directly through the tablet bed and cares for an immediate and efficient drying of the tablet cores.
