ABSTRACT:
A filtering flow box for receiving a supply of plastic pellets from a bottom-unloading tower silo and removing undesirable plastic strands (“angel hair”) from the pellets before they are processed for manufacturing. The box has an angled entry wall for laterally channeling pellets to an angled filter. The pellets pass through the filter and angel hair collects on the filter's upstream surface. The filter can be removed from the box at an angle having a vertical component for cleaning, thus allowing any pellets that have accumulated on top of the filter to fall back into the box.
