METHOD AND APPARATUS FOR FORMING SOLID CARBON DIOXIDE
Liquid carbon dioxide is transformed into solid snow and compressed into strands. A shroud defines an insulating plenum/volume surrounding a forming chamber, which reduces heat transfer to the forming chamber. A faction of gas phase flow resulting from the process fills the insulating plenum/volume, reducing heat transfer further.
Carbon dioxide or any suitable material is dispensed by a system into one or more containers. An impeller within a transport produces carbon dioxide particles at one or more desired sizes. Particles sized to be sufficiently small enough to still maintain particle integrity are produced and advance through the transport, while particles of insufficient integrity are directed toward a divert and a diverter prevents the insufficient particles from being misdirected into a separate transport passageway.
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.

A particle blast apparatus transport is capable of generating granular sized particles and delivering them without substantial storage to a single hose feeder assembly. The apparatus is configured to be used with solid blocks of cryogenic material, such as carbon dioxide, and with individual pellets of such material.
The outer periphery of a pelletizer barrel is devoid of obstructions allowing the number, location and size of vents to be maximized, thereby improving the flow rate of gas being vented from the interior chamber, allowing increased efficiency in and of production of pellets. Screens on the vents are disposed adjacent the inner surface of the barrel sidewall, reducing the volume within which snow can accumulate, thereby avoiding reduction in the venting of gas from the interior chamber resulting from snow accumulation in the vent passageways.

The media size changer is operably located in the diverging passageway and has one or more media size changing members to fragment moving blast media particles by impact therewith. The blast media particles are provided to the media blast nozzle in an initial consistent size, and when a moving blast media particle impacts with one or more media size changing members, two or more fragments of reduced size are created from the initial blast media particle for ejection from the nozzle device. The media size changer can be adjusted by an operator to eject whole particles or fragments of particles. The size of the ejected particle fragments can also be adjusted with the media size change

A particle blast apparatus has a pivoting hopper, allowing the hopper exit to move from or between a first position at which the exit is aligned with the feeder entrance to a second position where the hopper exit is not aligned as such. The hopper may emptied or cleared in this manner. The hopper may be provided with a device configured to impart energy to the hopper while the hopper exit is located at the second position.

Method and apparatus for forming carbon dioxide particles into a block
A block former comprises a portable device for compression forming of carbon dioxide particles into a non-homogenous block of carbon dioxide. The formed non-homogenous block can be used with carbon dioxide blasters that shave the formed block, and then eject the carbon dioxide shavings into a pneumatic jet as a blast media for cleaning surfaces. The block former further comprises a control system comprising a logic system of switches, valves, and timers to perform a timed sequence of events to form loose carbon dioxide particles into a non-homogenous block, to release compression on the block, and to eject the formed block from the block former. A single compression surface is provided to compress the carbon dioxide particles block, to release pressure on the block, and to eject the block from the block former device. The carbon dioxide particles used to form the non-homogeneous block can vary in size from snow to chunks or pellets.

Particle blast cleaning apparatus with pressurized container
A particle blast cleaning apparatus incorporates a pressurized container which is pressurized by the transport gas upon start up through a feeder which does not comprise an airlock. The feeder introduces the blast media into the transport stream. At start up, the transport gas pressurizes the container, flowing upwardly through the feeder until the container is substantially pressurized and the flow substantially ceases. The feeder rotor may be configured to crush or grind the particles.
