1. Dry Granulation

Dry granulation is a process that involves the compaction of powder materials into granules without the use of liquid. This method is commonly used when the materials are sensitive to moisture or heat.

According to a report by Grand View Research, the dry granulation market is expected to reach USD 5.4 billion by 2027, growing at a CAGR of 6.5% from 2020. This growth is driven by its advantages such as enhanced flow properties and easier handling of powders.

Applications of Dry Granulation

This method is frequently used in the pharmaceutical industry to produce tablets. Research indicates that approximately 75% of all tablet formulations benefit from dry granulation due to its cost-effectiveness and efficiency.

2. Wet Granulation

Wet granulation involves the addition of a liquid binding agent to form granules. This technique enhances the flowability and compressibility of powders, making it ideal for various pharmaceutical applications.

A study from the Journal of Pharmaceutical Sciences revealed that wet granulation is utilized in over 90% of the tablet manufacturing processes. This process is especially favored because it improves the homogeneity of the blend and ensures better content uniformity.

Benefits of Wet Granulation

The effectiveness of wet granulation can be observed in the production of controlled-release formulations. According to pharmaceutical analytics, about 80% of controlled-release drug products use wet granulation to optimize drug release profiles.

3. Extrusion Granulation

Extrusion granulation is a modern technique characterized by forcing a mixture through a die to create granules of uniform size. This method is gaining popularity due to its potential to produce high-quality granules with controlled size distribution.

The global granulation equipment market, which includes extrusion granulators, is projected to grow from USD 2.2 billion in 2020 to USD 3.5 billion by 2025, as stated by Mordor Intelligence. Extrusion granulation holds almost 30% of the granulation market owing to its scalability and efficiency.

Applications in Various Industries

Extrusion granulation is extensively used in producing both pharmaceuticals and food products. For instance, around 70% of dietary supplement companies have switched to extrusion methods for their granulation processes, citing improved product quality and reduced production times.

Conclusion

In summary, the 3 types of granulation—dry granulation, wet granulation, and extrusion granulation—offer distinct benefits and applications across various industries. As the market continues to evolve, understanding these methods will be essential for manufacturers looking to improve efficiency and product quality. The statistics and data provided in this article are intended to guide decision-making and showcase the relevance of granulation processes in today's manufacturing landscape.
