摘要： A particle blast cleaning apparatus for use with sublimable blast media, a source of compressed gas, and a discharge nozzle. The apparatus includes a mixing device for mixing the sublimable media with compressed gas, which mixing device includes a lower section having an outlet port formed therein and an upper section positioned over the lower section and having two sublimable media inlet ports and a compressed gas inlet port. A transfer member is mounted between the lower section and the upper section for reciprocal movement and has at least two transfer chambers for transporting sublimable media.

摘要： Carbon dioxide (CO.sub.2) solid discs (dry ice) are produced from liquid carbon dioxide injected into an extrusion cylinder in which the extrusion piston compresses dry snow and extrudes it through a fixed die, thereby producing pellets of dry ice which are fed by gravity into a forming cylinder chamber in which is operated a hydraulic cylinder compresses the pellets into discs. The operation is controlled by switches and hydraulic system.

The apparatus includes a mixing device for mixing the sublimable media with compressed gas, which mixing device includes a lower section having an outlet port formed therein and an upper section positioned over the lower section and having two sublimable media inlet ports and a compressed gas inlet port. A transfer member is mounted between the lower section and the upper section for reciprocal movement and has at least two transfer chambers for transporting sublimable media. A control mechanism is provided for controlling the flow of compressed gas to the compressed gas inlet port such that compressed gas is only provided to the compressed gas inlet port when at least one of the transfer chambers is in fluid communication with the compressed gas inlet port.
