Title: Dispensing system for porous floor containers

Abstract: A closed system for fluidizing and conveying solid particulate material from one or more porous floor supply containers to one or more receptor containers by means of aeration while preventing the release of aerated particulate material into the atmosphere. The system comprises at least one porous floor supply container which receives pressurized air to fluidize the particulate material and which feeds the fluidized mixture to a delivery conduit which communicates with the receptor container(s). The invention comprises venting the supply container to a material recovery unit to isolate the vented aeration air and all of the particulate material carried thereby and then readmitting at least said vented particulate material to the system, the vent air being passed through a filter before release to the atmosphere.
