The volumetric cup filler is the simplest form of product feeder to use and adjust in production situations. The cups are generally telescopic and can be adjusted within a pre-defined range depending on the product. Most uniform size and weight, free flowing products are ideally suited to a cup filler. The cup fillers shown is the type normall associated with a form fill and seal machine. It is fully synchronised to drop product at the right part of the production sequence. Cleaning is also very simple as the cups can be completely removed. Alternative sets of different sized cups can be substituted to cover a vast product weight range. With regard to smaller machines such as stick pack machines and sachet machines, the feeder is called a granule feeder but is much the same in operation.
