Mist cloud (1~3m/s)；It is 3 meters following again, then it is provided with the microwell plate obliquely upward to aperture, utilizes tangential gentle breeze and downward master
The a tail wind of thermally conductive wind synthesizes the whirlpool slowly rotated, and changing vertical drop have passed through constant rate of drying droplet motion profile, opens
Beginning rotates along helix；Since whirlpool revolving speed is very low, centrifugal force does not overcome gravity, and droplet dries path simply by change
(3~5m/s) extends droplet drying time, and will not deposit on side wall because centrifugal force is excessive.Even if there is a small amount of egg
White powder is scattering on side wall, can also be immediately exposed to tangential gentle breeze effect, and is blown off.
