  • Patent number: 4030879
    Abstract: An apparatus for drying ceramic bodies in which a framework of horizontal pipes and spacer bars define vertical columns beneath which a platform is disposed. The drying medium is circulated through the chamber containing the rack and through the pipes of the rack which have outlets for the cooling medium therealong. The ceramic bodies are stacked on the platform and the stacks are held pneumatically when the platform is lowered to remove the bottom article from each stack, additional articles being fed to the stack from the top. Plates on opposite sides of the stack are shifted back and forth by a crank arrangement to impart a quasi-sinusoidal movement to the gases around the bodies in the stacks.
