Abstract
A bulk adhesive handling system (10) having a hopper (16) and a lid (26) includes a vapor removal system (12) comprising a plurality of vent holes (40) formed in the side wall (42) of the hopper (16) of the system. The vent holes (40) are in communication with a venting plenum (44) surrounding the hopper (16), which is connected to a vacuum source (46). The vapor removal system (12) is adapted to withdraw gas from the hopper (16) when the lid (26) is in an open position and to withdraw air from an ambient source when the lid (26) is in a closed position.
