  • Cleaning method and apparatus
    Patent number: 4617064
    Abstract: A particle-blast cleaning apparatus using sublimable carbon dioxide pellets and a high pressure carrier gas. The apparatus includes a body which houses a rotary pellet transport. The transport conveys pellets from a gravity feed storage hopper to a high pressure carrier gas stream for application of the pellets to a discharge nozzle. Leakage of high pressure gas into the rotary transport is inhibited by the application of a force of gas seals which force is derived from carrier gas pressure. The apparatus enables the use of relatively high pressure carrier gas, the complexity and cost of the apparatus and method.
