The flow of powder in pharmaceutical processes dictates the quality of the product in terms of its weight and content uniformity. This article connects typical handling processes to flow property measurements that are essential to diagnose and avoid quality problems.

Powder and Bulk Engineering

Flow problems often occur because of poorly designed equipment. This article explains a methodical approach for designing, installing, and starting up equipment to achieve reliable flow.

Solutions to solids handling problems in existing systems are described. Some problems are solved by modifying the hopper or feeder to convert the flow pattern from funnel flow to mass flow. In other cases, chemical or mechanical flow aids are used.
