Tableting
In pharmaceutical products, there are various types of Tablets in a range of physical appearances, from high-gloss, rounded, sugar coated pieces to the geometric, punched shapes of film coated products. The shape, size and color are all visual characteristics reflected by the core and the coating such as sugar coat, film coat. The shape of the core is a key factor in the overall appearance of the Pharmaceutical tablet, not directly as a cosmetic influence, rather as the foundation for an applied coating system. There are various types of Pharmaceutical machineries and Processes to make Pharma products, Cosmetic products and Herbal Products.

Sugar Coated Tablet
Traditional sugar coating is performed in what is generally described as a conventional coating pan. However, the desire to reduce the time needed for the sugar coating process has led to the trend towards side-vented pans, which can be modified to introduce the sugar syrup via a dosing bar, rather than spraying the tablets as with film coating. Sugar coating liquids used in preparing sugar coated tablets contain binders such as gelatin or gum arabic so as to increase strength of the sugar coating layer or to increase bonding strength between an uncoated tablet and the sugar-coating layer.

Film Coated Tablets
Film coating is the largest sector of the tablet colouring market in Phrama industries. Film coating techniques reduce process times, offer greater control over coating parameters and provide more opportunity for innovation. Film coating involves the deposition of a thin polymer layer onto the tablet core, usually by a spray method. Conventional sugar panning equipment can be used but more specialized machinery, such as the side-vented pan, is used to control the processing conditions, which include temperature, humidity, spray rate and mixing of the tablet bed. Industry developments have led to the simplification, where possible, of film coating systems for shade criteria, microbial control and processing improvements.

Soft and Hard gelatin capsules
The basic difference between the hard and soft gelatin encapsulation processes is that in the hard gelatin capsule process, the capsule is prefabricated and supplied empty, whereas in the soft gelatin capsule process the encapsulation and filling take place simultaneously. |
