Abstract
A powder coating apparatus fluidizes coating powder in a powder container and mixes with the fluidized powder an additional substance, such as steam, water or other liquid. The additional substance is delivered into the interior of one or a plurality of enclosed bells which extend across the powder container. Each bell has a respective lower opening deep enough into the powder container to be immersed in the fluidized coating powder. The additional substance is delivered under pressure through a tube passing through the bell, through outlet nozzles in the tube and into the bell and then pressurizes the bell to keep the fluidized powder out of the bell and to deliver the additional substance out of the lower opening into the fluidized powder.
