The pharmaceutical tablet coating process involves spraying a coating solution onto the uncoated tablets as they move through the drum or coating pan. The resulting thin film is then dried by air passing through the device. In some cases, single or multiple drug layers can be coated on the tablets. Compression coating is not commonly used but is effective for certain types of tablets. It can separate incompatible ingredients that can't be dissolved by water. The process requires a special tablet machine. The process is applied by dipping tablets into a liquid coating and then drying them in conventional coating pans. This process may need to be repeated several times to achieve the desired coating thickness. However, it is a very effective method for coating conductive substrates. The coating is sprayed onto a charge surface and is capable of a complete uniform coat of all corners. Additionally, electrostatic coating is also useful for intagliations and other irregularities.
The tablet coating process can vary widely between manufacturers. The coating process must be uniform and durable and should not crack under stress. Various techniques were developed over the years for the purpose. Typical tablet coating involves sprinkling coating solutions onto the uncoated tablet surface and allowing the liquid portion to evaporate over the rotating pans. The tablets are then coated in one layer or in multiple layers. The process is complex and requires expertise to ensure the quality of the tablets.
A tablet coating process can enhance the efficiency and taste of pharmaceutical ingredients. Different coating processes can improve the taste of medications and make them more palatable and comfortable to swallow. It can also protect the pharmaceutical ingredients during transportation and distribution. In addition, some medicines need to be slowly released over a long period of time. Properly-chosen tablet coating processes will ensure better patient satisfaction and higher output. And with these processes, a tablet's effectiveness can be enhanced dramatically.
There are many different types of tablet coating systems available. A seed-drum popcorn coating process uses a high-performance airless spray system. This method is preferred for high-volume production because of its low maintenance requirements. The seeds are used to create a smooth, bright surface on the tablet. The seed-drum popcorn coating process is also more cost-effective than traditional methods. It is a great choice for sugar-coated tablets.
The Tablet Coater has two models. The patented air flow system and high spray volumes of the liquid are key to achieving a uniform coating on the tablet. The innovative air flow technology ensures that the process is as efficient as possible while meeting the strictest regulatory requirements.
