In the pharmaceutical industry, tablet coating application not only ensures the effectiveness of the active pharmaceutical preparation but also considers patient comfort. The unpleasant taste or smell of tablets can make it difficult for patients to take medications and negatively affect the treatment process. Therefore, the coating process of solid dosage forms such as capsules, granules, or tablets masks the taste of medications while also improving stability and release properties. However, humidity control plays a critical role during the coating process, and industrial dehumidifiers capable of producing air with low dew points come into play here. After mixing and shaping the tablet components in the production process, the tablet coating process applies a thin coating to the surface of pharmaceutical tablets to provide taste masking. This process also enhances the physical protection, chemical stability, and controlled release of the tablet. Since coating materials are generally water-based solutions, the humidity level of the environment must be carefully controlled during the process. Water-based solutions used in the coating process can adversely affect the coating operation in humid environments and make it difficult to apply the coating evenly and homogeneously. Industrial dehumidifiers keep the relative humidity of the environment at low levels, allowing coating to be performed at the desired quality and homogeneity during the coating process. In tablet coating, which is a dew point-based process designed around a target value of -15°C dP, dry air delivery should be avoided during the spraying of suspension into coating pans. Therefore, in tablet coating applications where industrial dehumidifiers are integrated, the process integration of the ventilation system should not be overlooked, and an automation system with appropriate infrastructure should be designed.
