Operations and troubleshooting for powder dispensing, sieving and blending — weighing, order of addition, blend uniformity, sampling, powder testing, cleaning and yield.
Capsule fillers and tablet presses fill by volume, so density, flow and moisture determine fill weight, weight variation and machine performance. These tests also guide formulation, equipment selection and hopper design, and support batch-to-batch consistency.
Weighing errors carry straight through into the batch and into test results, so every scale and balance must be calibrated, verified and used correctly.
