  • Method and apparatus for forming carbon dioxide particles into blocks
    Patent number: 8869551
    Abstract: An apparatus for forming a block 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 during block forming, with a shuttle discharging particles into the forming chamber while simultaneously pushing a previously formed block on to a conveyor. In one embodiment, the shuttle dosing cavity 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 than the volume of the forming cavity.
