- The Right Coating Material
Pan coaters are indispensable machines in the pharmaceutical sector, as they provide uniform and efficient coatings for tablets. This guide will cover all aspects of pan coaters including their components, working process and applications.
Components of the Pan Coater
- Drum : Rotates and holds the tablets during the coating procedure.
- Spray System : Spray evenly the coating solution on the tablets.
- Heating and Ventilation system: Controls the temperature and humidity in the drum to accelerate the drying process.
Working Process
- Tablet loading: Tablets loaded into the drum.
- Drum rotation: As the drum rotates, the tablets tumble.
- Application of Coating Solution: The spraying system evenly applies the coating solution.
- Drying: The heating system and ventilation system dries out the coating solution to form a uniform film.
Types of Pan Coaters
1.Standard Coating Pan
- Circular metal pan tilted 30 to 45 degrees.
- The tablets tumble down as the pan is rotated, ensuring an even coating.
- Equipped with a hot air blower and an air-atomized spraying system.
2.Perforated Pan
- A perforated cylinder that rotates horizontally in a housing.
- Spraying nozzles evenly distribute the coating solution on the tablets.
- Standard pans are more efficient at drying and have a higher coating capacity.
Common Types of Coatings
- Sugar Coating Improves the taste and appearance of the tablet.
- Film Coating Protects the tablet while controlling drug release.
- Enteric Coating: This coating ensures that the drug is released into the intestines and not the stomach.
The Right Coating Material
The choice of coating material is important. The tablet's use and administration method will determine the coating material. Enteric coating materials, for example, need to be acid resistant, while film coatings need good adhesion, mechanical strength, and adhesion.
What is a Pan Coater ?
- A pan coater creates a protective film by spraying and rotating.
What are the main functions a Pan Coater performs?
- The primary functions of the tablet are to protect, improve appearance and control drug release.
Which factors should be taken into consideration when choosing a pan coater?
- Consider the following: capacity, efficiency, ease-of-operation, coating uniformity and maintenance costs.
What is the advantage of a pan coater compared to a liquid bed coater?
- Pan coaters are ideal for large-scale production. They have a gentler process of coating, which makes them ideal for tablets.
How do you maintain and care for your Pan Coater?
- Check and replace worn parts and clean the drum and spray system regularly. Also, make sure the heating and ventilation system is working correctly.
Pan coaters are an essential piece of equipment for the pharmaceutical industry. They provide efficient coating functions to enhance tablet quality and improve patient experience. The right pan coater can improve product quality and production efficiency.
