An apparatus (2) for forming one or more blocks (108) from carbon dioxide particle is configured to allow changing between precise thicknesses with very little downtime, utilizing both weight based and volumetric dosing. A spacer supports the lower ejection piston (74) during block forming, with a shuttle (102) discharging particles into the forming chamber while simultaneously pushing one or more previously formed blocks (108) on to a conveyor. In one embodiment, the shuttle dosing cavity (104) has a volume that is greater than the volume of the forming chamber volume, which allows more pellets, volumetrically, to be dosed into the dosing cavity (104) than the volume of the forming cavity. |
