    This is the most common method of coating tablets in the pharmaceutical business. It adds personality to the tablet and stabilizes the chemical composition through the use of different colors. The pill’s disagreeable aroma and flavour are likewise concealed.

    Tablets are coated with film solutions using a sprayer in this method. The polymer, plasticizes, solvent, and dye solution are mixed once, and then the process is complete.

    A spinning tablet pan sprays and quickly dries the tablets. A thin polymer film forms a protective barrier around the tablet when it has dried. The tablet may retain its color, but this can be changed by adding other colors to the solution.

    Tablet coating machine are currently available in a wide variety of configurations. The following are the three primary divisions: education, entertainment, and government.

    Traditional Pan

    Pan with Holes

    Processor for Fluidized Beds


    Also VJ Instruments provides with many other products used in pharmaceutical industry like

    Ball mill in pharmaceutics, Morris water maze which are widely used in this industry.


    Applied Film Coating

    In a solvent, polymers, plasticizes, dyes, and pigments are dissolved and sprayed into a tablet coating machine. To ensure that the film is well coated, you must keep the tablets in the pan at all times. Spray nozzle to tablet bed distance should be measured accurately to provide equal stacking. In most cases, the coating solution atomizes into extremely small droplets. The sprayer will disseminate the coating solution on the bed as the coating pan spins with the tablets. A multi-sprayer system is standard on most of these devices. Hot air removes the vapour from the tablet after it has been coated with solvent droplets. In a single-stage technique, this occurs, resulting in a 2-3% increase in tablet weight. As a result of this drying process, each tablet is coated with what is known as a “film.”

    Tablet coating has been around in the oral solid dosage industry for well over a century. Originally invented as a method to make taking tablets more palatable, tablet coating in today’s pharmaceutical industry has evolved to make pharmaceutical ingredients more effective. Timed release, flavor masking, and tablet protection are just a few of the reasons why a coating is applied to a tablet during the manufacturing process. They have launched a brand new tablet coater,  which capitalizes on decades of expertise from the former Manesty product brand as well as the current technological advancements coming from our . It offers an extremely flexible and streamlined  coater for a variety of different coating applications.

    Around closed charging, sampling, and discharging. Building the drum coater around closed material handling naturally means it is an ideal drum coater for highly potent active ingredients.



    Tablet Coating:

    Tablet coating is a common pharmaceutical technique of applying a thin polymer-based film to a tablet or a granule containing active pharmaceutical ingredients (APIs). Solid dosage forms are coated for a number of reasons, the most important of which is controlling the release profiles. The amount of coating on the surface of a tablet is critical to the effectiveness of the oral dosage form. Tablets are usually coated in horizontal rotating pans with the coating solution sprayed onto the free surface of the tablet bed. The advantages of tablet coating are taste masking, odour masking, physical and chemical protection, protects the drug from the gastric environment etc. There are various techniques for tablet coating such as sugar coating, film coating, and enteric coating. Recent trends in pharmaceutical technologies are the development of coating methods which overcomes the various disadvantages associated with solvent based coatings. In these latest technologies coating materials are directly coated onto the surface of solid dosage forms without using any solvent. Various solvent less coatings are available such as electrostatic dry coating, magnetically assisted impaction coating, compression coating, hot melt coating, powder coating, and supercritical fluid coating. Super-cell Coating Technology is a revolutionary tablet coating that accurately deposits controlled amounts of coating materials on tablets even if they are extremely hygroscopic or friable. Magnetically assisted impaction coating, electrostatic dry coating in solvent-less coatings, aqueous film coating and Super-cell coating technology are also available recent technique of coating. An ideal tablet should be free from any visual defect or functional defect. The advancements and innovations in tablet manufacture have not decreased the problems, often encountered in the production, instead have increased the problems, mainly because of the complexities of tablet presses; and/or the greater demands of quality. This review deal in detail about history, recent tablet coating technique and remedies associated with the tablet coating.
