Abstract
The device has an opening provided through a side wall of the fluidization enclosure and a tube extends outside a enclosure and substantially perpendicular thereto. A duct is connected substantially perpendicularly to the tube and extends downwards. A piston is slidably mounted in sealed manner inside the tube to slide between a first position in which it constitutes a panel closing the opening and a second position in which it at least partially uncovers the opening of the duct into the tube, and control means for controlling displacement of the piston inside the tube.
