Net weigh vibratory fillers are suitable for dispensing most dry free flowing  products: examples include but are not limited to:  powders, pellets, nuts/seeds, coffee(WB and Ground), granola, popcorn, herbs.  They are also suitable for weigh counting and for filling small parts into packages. Dupre Solutions Vibratory Scale   Model Simplex 1 H 3L  features a single vibratory feeder system with dual stage speed controls. The initial stage involves high vibration to “Coarse Feed” product into the weigh-bucket as fast as possible to 80% or 90% of the  final packaged weight. Once this threshold weight  has been reached, the PLC reduces vibration, closes the course gate so width is restricted , and  a narrow  stream of product is “fine feed ” into the weigh bucket to reach the final target weight. Behind the scene the system automatically makes small adjustments to amplitude and target values to achieve the most accurate weighments and increased performance.
