The intermediate portion (23) is configured to enable the deposit and accumulation of a predetermined quantity of granular material coming from the inlet opening (21); Motor means are provided which can be activated on command to cause the granular material to flow in advancement from the intermediate portion (23) towards the outlet opening (22).

A method of producing a plurality of parts includes placing a sol mixture into a cavity of a tool, optionally placing a metal foil over a top of the cavity and placing a graphite gasket over the metal foil, and securing the tool with the sol mixture to form a tooling capsule. Tooling capsules are placed within a conveyor system and are heated until the solvent of the sol mixture reaches at least supercritical conditions of the solvent. Pressure is released within each of the tooling capsules after the supercritical conditions are reached, and then the tooling capsules are cooled to approximately room temperature. The parts are removed from the tooling capsules, and the method is continuous.
