Pan Granulation Process

The pan granulation process involves the following steps:

1. Mixing: The powders are mixed together in a pan.
2. Wetting: A binder solution is added to the powders, which causes them to agglomerate and form granules.
3. Drying: The granules are dried in a pan, which causes them to harden and become spherical.
4. Screening: The granules are screened to remove any oversized or undersized particles.

Pan Granulator Types

There are two main types of pan granulators:

1. Conventional pan granulators: These granulators have a horizontal pan that rotates on a central axis. The powders are mixed together in the pan, and the binder solution is added through a spray nozzle.
2. High-shear pan granulators: These granulators have a vertical pan that rotates on a central axis. The powders are mixed together in the pan, and the binder solution is added through a high-shear impeller.

Pan Granulator Design

The design of a pan granulator will depend on the specific application. Some of the key design features include:

1. Pan size: The size of the pan will depend on the batch size.
2. Pan shape: The shape of the pan will depend on the type of granulation process.
3. Pan material: The material of the pan will depend on the chemical compatibility of the powders and the binder solution.
4. Impeller type: The type of impeller will depend on the type of granulation process.
5. Spray nozzle type: The type of spray nozzle will depend on the type of binder solution.

Pan Granulator Operation

The operation of a pan granulator will depend on the specific application. Some of the key operating parameters include:

1. Rotation speed: The rotation speed of the pan will depend on the type of granulation process.
2. Temperature: The temperature of the pan will depend on the drying process.
3. Binder solution flow rate: The flow rate of the binder solution will depend on the type of binder solution and the granulation process.
4. Impeller speed: The speed of the impeller will depend on the type of granulation process.

Pan Granulator Troubleshooting

Some of the most common problems that can occur with pan granulators include:

1. Granules are not spherical: This can be caused by a number of factors, such as the incorrect binder solution, the incorrect impeller speed, or the incorrect pan temperature.
2. Granules are too large: This can be caused by a number of factors, such as the incorrect binder solution, the incorrect impeller speed, or the incorrect pan temperature.
3. Granules are too small: This can be caused by a number of factors, such as the incorrect binder solution, the incorrect impeller speed, or the incorrect pan temperature.
4. Granules are not uniform: This can be caused by a number of factors, such as the incorrect binder solution, the incorrect impeller speed, or the incorrect pan temperature.

Pan Granulator Validation

The validation of a pan granulator is a critical step in ensuring that the granulator is operating correctly. Validation involves testing the granulator to ensure that it meets the specifications for the specific application.

Pan Granulator Maintenance

The maintenance of a pan granulator is essential to ensure that the granulator is operating correctly. Maintenance involves cleaning the granulator, inspecting the granulator, and lubricating the granulator.

Pan Granulator Applications

Pan granulators are used in a variety of pharmaceutical applications, such as:

1. Tablets: Pan granulators are used to create granules for tablets. Granules are used in tablets because they are more uniform in size and shape than powders, which results in tablets that are more consistent in quality.
2. Capsules: Pan granulators are used to create granules for capsules. Granules are used in capsules because they are more easily filled into capsules than powders.
3. Sachets: Pan granulators are used to create granules for sachets. Granules are used in sachets because they are more easily dissolved in water than powders.

Pan Granulator Market

The pan granulator market is a global market that is expected to reach $1.5 billion by 2025. The growth of the market is being driven by the increasing demand for pharmaceutical products.

Pan Granulator Suppliers

There are a number of suppliers of pan granulators, such as:

1. GEA: GEA is a global supplier of pan granulators. GEA offers a range of pan granulators, including conventional pan granulators and high-shear pan granulators.
