Tablet coating is a process where particles tumble in a rotating bed and are coated with a solution. To speed up this process the incoming air can be heated, however, there is a fine balance between the rate at which solvent can be evaporated and the rate at which the coating liquid can be introduced. FILM COATING:- As the sugar coating process is very time consuming and is dependent on the skills of the coating operator, this technique has been replaced by film coating technology. Thus, for a good tablet coating, control of process parameters is very important. Then your tablets will be coated by the solution quickly. Tablet coatings must be stable and strong enough to survive the handling of the tablet, must not make tablets stick together during the coating process, and must follow the fine contours of embossed characters or logos on tablets. Their novel tablet coating process required the development of a bespoke manufacturing system. Risk assessment of a typical non-functional coating process was conducted to set the process parameters systematically. Tablet "hardness", also called "breaking force", is tested to assure that the tablet's strength will survive all further processes, such as dedusting, coating and packaging. The next process is tablet spinning, whereby the tablets are put in a drum and rotating it in an orbital way, the streamlined plates control most of the operations. The science of AF (Anti-Fingerprint) Tablet Glass Coatings. The process of coating one or more layers of polymer onto tablets is almost ubiquitous in pharmaceutical manufacturing 1 to achieve dosage forms that exhibit uniformity in color from an aesthetic point of view or to achieve light protection, taste masking, and, more recently, in advanced coatings for active and modified release. The process of film coating involves consistently depositing and drying a uniform coating formulation onto the surface of a substrate so as to form a uniform film.

Black spots problem is observed in some organisations sometimes it has led to destruction of whole batch also. Despite automation of control procedures also approaches of in-line process analytical technology (PAT) become more relevant. The tablet coating process. Anti-Fingerprint Tablet Coating Process. 3 primary components of tablet coating are tablet properties, coating process and coating composition. The solvent is removed during the coating process by the flow of air through the coating machine. Tablet Coating Tablet coating is the process of evenly covering particles with a substance by applying a series of thin layers. Tablet press lubrication and powder dispersing for tablet coating are both processes which can be significantly enhanced using Coperion K-Tron pharmaceutical feeders. Tablet film coating is a technology-driven process and the evolution of coated dosage forms relies on advancements in coating technology, equipment, analytical techniques, and coating materials. This review covers a brief overview of tablet film coating technology and modeling approaches, with a focus on recent advancements in pharmaceutical applications. O’Hara’s knowledge of the tablet coating process has allowed them to optimise their tablet coater design to ensure the application of the coating solution to the tablets does not result in the tablets sticking together, and that the tablet coating solution is evenly applied to follow the fine embossed designs of the tablet. A poorly developed film coating process may result in various tablet defects like chipping, edge process variables of tablet film coating [8]. The tablet coating have number of advantages like masking odor, taste, color of the drug, providing physical and chemical protection to drug, Protecting drug from the gastric environment. The process involves spraying of a solution of polymer, pigments and plasticizer onto a rotating tablet bed to form a thin, uniform film on the tablet surface. Read More 2. Tablet film coating is a common but critical process providing various functionalities to tablets, thereby meeting diverse clinical needs and increasing the value of oral solid dosage forms. The coating pan is actually a perforated drum that rotates within a cabinet. A primary component of this process is a circular metal pan that is slightly tilted on a benchtop stand. Since the AutoCoater® range is modular, the same technology is available right from 1 kg to 1000 kg batch sizes. During the tablet coating process, a batch of tablets is loaded into the metal pan, and it is set to rotate. The coating runs with both of the new formulations were performed at high tablet bed humidity condition (process conditions used were the same as run B with gun-to-bed distance at 4.5 in., resulting in close to 40% tablet bed RH), a condition known to produce high incidence of logo bridging for the HPMC/PEG 400 system. The last critical step in the tablet production cycle is tablet coating after solving problems in core tablet manufacturing.After finding the tablet coating defects and their remedies, you will successfully complete the tablet production cycle. The physical properties of a tablet are tested either by manual or automated sampling and IPC testing (in-process control). The coating suspension is pumped through the spray guns with compressed (atomising) air which forms a spray of fine droplets As the suspension droplets hit the tablet surface they should spread into a film before the solvent is rapidly removed by the throughput air TABLETTING PROCESS: Tablet Press: 13. Purpose: Novel tablet coating approaches include the development of continuous coating technologies. Table 4 shows the cause and effect diagram of a typical non-functional film coating process, which summarizes the relationship among the CQA of tablet appearance, process time, output parameters, and process parameters. Types of Tablet Coating Machines (Focusing on Coating Process) Well, you can choose a tablet coater system depending on the following key processes: Sugar coating: It is the process of covering tablets with a sugar layer that can either be colored or uncolored. Extend holding period for tablets prior to coating process ; Related: Film Coating Process of Tablets in Pharma Manufacturing. 12.
