Gastight and vacuum-tight chamber intended to be used in a device for
heating a product advancing inside the chamber by electromagnetic
induction, characterized in that it comprises a gastight and vacuum-tight
sheath made of an electrically insulating, gastight and vacuum-tight
material, the inner faces of the sheath being protected by a heat shield
consisting of a matrix of tiles made of a thermally insulating material
and of a plurality of tubes cooled by the flow of a fluid, the latter
being trapped in the matrix of tiles.
