Processing steps
Step Date Type Process Changes
#1 mechanical Droplets of liquid water were produced using a garden sprayer, over a container filled with liquid nitrogen. 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.
#3 mechanical The ice particles were sieved using two sieves of 200 and 400 µm. Spherical water ice particles of size between 200 and 400 µm are selected.
