The machine consists of a motor/blower assembly, a nozzle system, nozzle
housing, a formulation tank and a metering valve. The various components are
identified in a diagram below. The blower is a single stage/centrifugal
impeller/axial flow driven by a universal motor operating at a speed of about
20,000 RPM. The blower moves a large amount of air through the nozzle system
consisting of three individual nozzles, each of which has two sets of directing
vanes. One vane set causes the air to be rotated clockwise and the other causes
the air to be rotated counterclockwise. The intersection action of the circula r
forces shears the material being dispensed into small particles. Further, the ai r
rushing by the specially shaped liquid tubes creates a negative pressure in the
liquid tube. This negative pressure causes the liquid to be drawn from the
formulation tank through the control valve and into the nozzle system where it is
pneumatically sheared into aerosol or mist size droplets. After break-up, the
droplets are driven away from the machine by the air passing through the nozzle
system.
Generally, the size of the output droplets increases with increasing
flow rate and with increasing viscosity.
