Abstract
A device for the production of a green from slurry by solidification after injection into a mold having a temperature of less than 0.degree. C. The device includes a mold having a jack wherein moveable parts of the jack ensure closure thereof and which are housed within a gas-tight vessel. A distributor for dry gas with a dew point lower then the temperature of the mold emits a gas current into the vessel through apertures. A chute conducts the green towards an exit aperture and to a receiving member outside the vessel.
