Processing steps
Step Date Type Process Changes
#1 mechanical The liquid water is injected into a sonotrode and spread out as a thin film on the conical shaped nozzle surface at the output of the sonotrode. Ultrasonic vibrations delivered to the sonotrode nozzle disintegrate the liquid into micro-droplets. Spherical liquid water droplets are formed.
#2 thermal The droplets of deionized/ultra-pure water, initially liquid, undergo solidification as they contact the liquid nitrogen Spherical water ice particles are formed.
