Application Note: Refilling Loss-In-Weight Feeders Via Pneumatic Conveying In Continuous Pharmaceutical Processes

The mode of refill of product to a Loss-in-Weight (LIW) feeder that is feeding a continuous pharmaceutical process can be almost as critical as choosing the right feeder technology. Since the objective of feeder refill is to refill as quickly as possible, pneumatic receivers that operate under a dilute phase vacuum transfer principle are often used as refill devices, particularly for continuous operations.
