This section addresses the design, operation, and qualification of equipment used in solid oral dosage manufacturing. It includes blenders, granulators, tablet presses, coaters, and capsule filling machines. Emphasis is placed on critical process parameters, mixing and compression control, uniformity verification, equipment qualification, and integration with process validation to ensure consistent product quality and reproducible manufacturing performance.
Blending and mixing operations are used to distribute active pharmaceutical ingredients and excipients uniformly throughout a powder mixture so that each dosage unit contains the intended composition. Unlike milling operations, which reduce particle size, blending processes combine particles while preserving…
Capsule filling equipment is used in pharmaceutical manufacturing to fill hard gelatin or hydroxypropyl methylcellulose (HPMC) capsules with powders, granules, pellets, or other solid formulations. The filling operation converts a prepared formulation into a finished oral dosage form by accurately…
Coating equipment is used in pharmaceutical manufacturing to apply a uniform layer of coating material onto tablets, pellets, or capsules. The coating process improves product stability, modifies drug release characteristics, enhances appearance, and can provide protection from moisture, light, or…
1. Overview Containment and dust collection systems are used in pharmaceutical manufacturing to control airborne particulate generated during material handling and solid dosage processing. Many operations such as powder dispensing, milling, blending, granulation, and tablet compression generate fine particulate that…
Material dispensing and handling represent the first controlled mechanical stage in solid dosage manufacturing. At this point the process transitions from warehouse-controlled inventory to manufacturing-controlled materials. Accuracy of weighing, integrity of material identification, and prevention of cross-contamination must be established…
Drying is a critical unit operation in pharmaceutical solid dosage manufacturing. Following wet granulation, granules contain residual solvent or water from the binder solution. The drying process removes this moisture to achieve a stable granule structure with controlled residual moisture…
Granulation is a controlled particle enlargement process used in pharmaceutical solid dosage manufacturing to improve powder flow, compressibility, and content uniformity. Fine powders frequently exhibit poor flow behavior, electrostatic cohesion, and segregation during handling. Granulation converts these powders into stable…
1. Overview In-process inspection equipment is used during pharmaceutical manufacturing to monitor product quality attributes while production is underway. These systems detect defects, contamination, and process deviations in real time and remove non-conforming units before they proceed to downstream operations….
Particle size control is an important step in many solid dosage manufacturing processes. Milling equipment is used to reduce particle size, break agglomerates, and produce powders with a controlled size distribution suitable for blending, granulation, or direct compression. Particle size…
Tablet compression is the final critical unit operation in the manufacture of solid oral dosage forms. During this step, dried and blended granules are compressed into tablets of defined weight, hardness, thickness, and content uniformity. The compression process transforms free-flowing…
