Optimising Pharmaceutical Processing: Innovative Solutions

Pharmaceutical processing involves the manufacturing of medicinal products, which requires the precise handling of raw materials to ensure the efficacy and safety of the end product. The production of solid dosage forms, such as tablets and capsules, involves various unit operations that require the optimisation of processing parameters to achieve desired quality attributes.

One critical aspect of solid dosage form manufacturing is particle size reduction, which is necessary to improve the flowability and compressibility of powders. In this regard, conical milling and rotary sifting are two unit operations that are commonly used in pharmaceutical processing to optimise particle size reduction and powder flowability.

Conical Milling

Conical milling is a type of size reduction process that involves the use of a conical-shaped mill, which is designed to break down particles into smaller sizes. The conical mill operates by feeding the material into the top of the mill and allowing it to flow down the conical shape of the mill.

The material is subjected to high shear forces, which break the particles down into smaller sizes. The smaller particles are then discharged through the bottom of the mill, while the larger particles are recirculated back into the milling chamber until they reach the desired size.

Conical milling is an efficient process for reducing particle size and achieving narrow particle size distributions. The process is also suitable for materials that are difficult to mill, such as heat-sensitive and abrasive materials. Additionally, conical milling can be used in conjunction with other unit operations, such as wet granulation, to improve the efficiency of the overall process.

Key Application

Particle Size Reduction

Particle size reduction is a critical process in pharmaceutical processing, as it affects the flowability, compressibility, and dissolution characteristics of powders. Conical milling and rotary sifting are two unit operations that are commonly used to optimise particle size reduction and achieve narrow particle size distributions.

Rotary Sifting

Rotary sifting is a process that involves the use of a rotating cylindrical screen that separates particles based on size. The material to be sifted is fed into the top of the screen, and as the screen rotates, smaller particles fall through the screen while larger particles are retained on the screen.

Rotary sifting is an effective method of separating particles and removing oversize and undersize particles. The process is commonly used in pharmaceutical processing to remove oversize particles before further processing, such as tableting or encapsulation. Rotary sifting is superior method of security screening and deagglomeration as compared to vibratory sifter to reduce time, manpower & increase production output. Rotary sifters saves the number of machines in the production floor as well as reduces dusting and is much more efficient method.

Security Screening

Security screening is an important aspect of pharmaceutical processing, particularly for materials that are prone to contamination. Security screening involves the use of metal detectors and x-ray inspection systems to detect and remove metal fragments and other contaminants from the material.

Conclusion

The pharmaceutical industry is constantly evolving, and manufacturers are continually looking for ways to optimise their processes to improve the quality and efficacy of their products. Conical milling and rotary sifting are two unit operations that have become essential in pharmaceutical processing due to their ability to optimise particle size reduction and powder flowability.

Digitalisation is also transforming pharmaceutical processing, with the adoption of advanced software solutions and data analytics tools. These technologies enable manufacturers to collect, store, and analyse data from various sources, providing them with greater insights into their processes and enabling them to optimise their operations.

Hence, the pharmaceutical industry is rapidly evolving, and manufacturers are continually looking for ways to optimise their processes to improve product quality and efficacy. Conical milling and rotary sifting are just two examples of the unit operations that are becoming essential in pharmaceutical processing. However, the industry is also witnessing a trend towards the use of advanced technologies, such as continuous manufacturing, PAT, and digitalisation, which are transforming pharmaceutical processing and enabling manufacturers to achieve greater efficiency, control, and safety.
