Abstract
A process of creating an aerosol includes coating at least one of a pair of counter-rotating, adjacent rollers with a fluid, the pair of counter-rotating rollers defining a nip therebetween, rotating the counter-rotating rollers to cause the fluid to be drawn into an upstream side of the nip, causing fluid filaments of the fluid to form on a downstream side of the nip, the fluid filaments stretching between respective surfaces of the pair of counter-rotating rollers and breaking into droplets on the downstream side of the nip, and harvesting the droplets at the downstream side of the nip.
Claims19
A process of creating an aerosol, comprising:
- coating at least one of a pair of counter-rotating, adjacent rollers with a fluid, the pair of counter-rotating rollers defining a nip therebetween;
- rotating the pair of counter-rotating, adjacent rollers in counter rotation with respect to each other to cause the fluid coating to be drawn into an upstream side of the nip to a downstream side of the nip, such that the fluid adheres to surfaces of each of the rollers;
- causing fluid filaments of the fluid to form on a downstream side of the nip, the fluid filaments formed by stretching the fluid between respective surfaces of the pair of counter-rotating, adjacent rollers, until the filaments break into droplets on the downstream side of the nip;
- and
- harvesting the droplets at the downstream side of the nip.
