摘要
Two overlapping rows of eight and nine rectangular venturi nozzles (4) direct a high speed stream of gaseous carbonic acid containing hard carbonic acid crystals at the work surface (2) same 60mm away. The venturi block (1) is of copper or aluminium and contains heater elements (11) and a temperature sensor (12), which forms part of a control system to maintain the temperature between 17 and 35 degrees Celsius.
