MPE announces its in-line puck knocker for reducing product carryover in its tubular drag conveyor systems. Its design is simple, effective, and makes for easy installation. It is entirely stainless steel, installing on the intake side of any system drive turnaround. Each puck gently glides along the knocker's triangular ramp until it releases into suspension. The controlled agitation causes any residual product to fall off the chain and pucks and produces a subtle knocking sound. In lab testing, the in-line puck knocker resulted in as much as six times less carryover.
