Unit fills quickly and accurately
HealthStar (Braintree, MA) offers its "Purefil 1000" walking-beam flow-meter filler, which is adapted for clean filling environments in the pharmaceutical industry. The in-line machine fills as many as 300 containers/min. The device handles container sizes from small vials to 1-L units.
HealthStar designs and manufactures the filler's nozzles in house. Various nozzles are available to handle foamy, watery, and viscous products. The device incorporates magnetic flow meters that measure and disperse product. The meters ensure a filling accuracy of 0.25%. In addition, a sensor confirms the presence of a container before filling.
The filler is completely servo-driven and features programmable logic control. Operators can program as many as 32 different batches into the machine. The filler can be cleaned in place, and changeover can be accomplished in 20–30 min.
