<p>A dry-ice blast device (A) comprising a low pressure air compressor (2) serving as an air compression source, having a delivery pressure of 1.2-2.5 atmospheres. Dry-ice particles feeding means (5, 6) are installed to mix dry-ice particles (D) in an air current in a place upstream of the nozzle (32) of an air conveyance path (3). Such arrangement makes low pressure blast possible, suppressing the attrition of dry-ice particles (D) and production of noise, reducing the size and weight of the entire device, and improving handiness.</p> |
