High Efficiency Tablet Film Coating Machine In Pharmaceutical Industry . Ideally, the spray pattern must meet the tablet surface and cover almost the entire tablet bed. The coating of OSD in pharmaceuticals has been practised since time immemorial. However, this coating technique is not as popular in the pharmaceutical industry as it was once, due to the laborious procedure and long process time, a requirement of skilled and trained personnel, and the inability to emboss, print or label the tablet and increases the size and weight of the tablet. That one change made coating times drop and process throughputs skyrocket across the industry. This field is for validation purposes and should be left unchanged. 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). What is pharmaceutical manufacturing • it is the process of industrial scale synthesis of pharmaceutical drug by pharmaceutical companies. 3. The pharmaceutical coating can be applied to a wide range of Solid Oral Dosage forms including tablets, granules, crystals, powdersor pellets. Automatic coaters are used for all kinds of coatings; they can be equipped with a remote control panel, a dehumidifier, and dust collectors. film coating resulting from the spraying and subsequent drying of solutions or dispersions. Though the stages differ from one manufacturer to another, a typical sugar-coating process involves the following steps: Sealing; Subcoating; Smoothing (or Grossing) Colouring/ Colour coating; Polishing (or Glossing) Printing; Sugar coats are often shiny and highly coloured. A process where a thin polymer-based layer having a thickness between 20 and 100 µm is applied to the OSD which may be a tablet, granules or pellets is called film coating. Drum loading—when tablets are first loaded, check broken, capped or chipped tablets. Listing of Alarms, warnings & safety interlocks expected with specific and immediate action such as cycle stop, operator alert etc. Mixing efficiency of the coating pan also decreases with partially loaded pans, requiring an increased rotation speed of the coating drum. Film-coating formulations usually contain the following components: Particle/ Granule or pellet coating is a thin layer of a substance that is placed around a core particle, granules or pellets. It is not only limited to the pharma sector but also widely used in FMCG and food industry. The technologies include Microencapsulation, top spray and bottom spray (tangential or Wurster coating).

The selection of instruments to measure the appropriate parameters; how the coating process may be optimized and the process scaled-up to control the coating of production size batches successfully. Reducing coating solids to facilitate more even coating distribution. The coating itself can serve several functions – it can strengthen the tablet, control the release of active ingredients, improve its taste, provide colour, make it easier to package and handle, and protect it from moisture. The film coating process begins with the loading of a batch of tablets into the coating drum. Different Active Pharmaceutical Ingredients and (excipients) have different tastes or odour, some may be mildly bitter, yet some of them may be very bitter. However, it is very capital intensive and requires a massive facility for production. enhances mechanical properties (abrasion & compressibility), improves aesthetic appeal (Texture, appearance, odour and taste), and. However, high negative pressures must be avoided to ensure that some spray is not lost via the air exhaust port. If the guns are too close, the spray width would be narrow resulting to non-uniform coating. The process of sugar-coating involves. • Excessive pan speed in coating process - Reduce pan speed • Spray rate too low - Increase spray rate ... Ankur Choudhary is India's first professional pharmaceutical blogger, author and founder of Pharmaceutical Guidelines, a widely-read pharmaceutical blog since 2008. Sun Coating Company provides many different coating processes to the pharmaceutical industry. Coating is a process by which an essentially dry, outer layer of coating material is applied to the surface of a dosage form in order to confer specific benefits that broadly ranges from facilitating product identification to modifying drug release from the dosage form. Other methods include fluidized bed coating, dry coating, but the most widely used method in the pharmaceutical and nutraceutical industry today is that of film coating. The modification is effective with osmotic release oral delivery systems, enteric (delayed-release) or sustained-release coating. The use of stabilizers added to the coating ingredients help to protect drugs from light sensitivity, moisture and drugs that degrade due to atmospheric oxidation. This layer is in the range of 20 to 200 μm in thickness, or around 1 to 9% of the initial weight of the tablet. Also, it was not until the mid-twentieth century that colours became an essential addition to the coating in the pharma industry. Senior Citizens and children find it difficult to swallow or gulp some oral dosage forms. For the best experience on our site, be sure to turn on Javascript in your browser.

This article describes the essential process steps and equipment required for film coating tablets. This results in wastage of the coating material and may lead to other problems such as picking and sticking. The simple 2-port gun has one port for the liquid coating solution and the other is for the atomizing air. Increasing the amount of coating applied to allow better and more consistent tablet coverage. The time taken to achieve this can range from a few minutes to several hours and is governed by the particular characteristics of the coating material, as well as the process parameters such as drum speed, temperature, pressure and spray rate. The secret of film coating is very similar to spray-painting – it is best to spray lightly and evenly so that successive thin coatings are allowed to build up to create a robust dense layer on the surface of the tablet. Film coating has evolved with time, keeping pace with demands of the pharma industry. Subscribe to our blog to receive all updates directly in your mailbox. In 2011, L.B. Balancing both spray rates and drying conditions to achieve good coating process efficiency (typically > 90% and ideally > 95%). It is a single-stage process that is faster and increases the tablet weight marginally by only 2-3% in comparison with the sugar coating process, which results in an addition of 60 to 80% additional weight. Coating pans are used mostly to sugar coat pellets. Spray Rate – Film Coating Process Monitoring the spray delivery rate, is crucial especially in aqueous film coating as variations in the spray rate during the coating process can lead to several problems, such as picking and sticking, orange peeling and frosting.and erosion, all of which are caused by over-wetting of the tablets. Developed continuously in the last decades, coating technology originally derived from dragée pan processing. Monitoring the spray delivery rate, is crucial especially in aqueous film coating as variations in the spray rate during the coating process can lead to several problems, such as picking and sticking, orange peeling and frosting.and erosion, all of which are caused by over-wetting of the tablets. Most coating processes take place for drug stability improvement, drug release modification and taste masking. Product Description . This type of pump allows for accurate control of rate which depends only on the tubing size used in the pump and the speed of rotation of the pump.

Please use the form below to get in touch. Compression coating is similar to the tablet technology, where the core or coated tablets are surrounded by compressible excipients, which prevents the drug incompatibilities and protects the drug from environmental factors like light, humidity and oxidation. These are heated in a stream of flowing air and time allowed for dust to settle and a steady temperature of the outlet air to be reached (typically 40 to 46°C). To get the required spray width, it is important to optimize the gun-to-gun distance and the gun-to-bed distance. Above all these parameters must be carefully controlled for the whole length of the coating process. At the same time, a positive pressure in the drum must also be avoided as this may cause contamination of the environment when the drum door is opened due to the release of dust particles and hot air, both of which are prohibited by GMP.
