Modular spray unit and method for controlled droplet atomization and controlled projection of droplets

An apparatus for producing atomized droplets for spraying on a spray surface comprising:

• means for producing controlled atomization droplets and for projecting the droplets in the same general direction, including
• spinning cone means,
• air blower means for forming a fluid film on the spinning cone means and for moving the fluid film forward on the spinning cone means to produce a force vector tangential to the rotating axis of the spinning cone means, the spinning cone means shearing the fluid film into the atomization droplets, and
• the air blower means controlling projection of the atomization droplets in the same general direction for :praying on agricultural or horticultural spray surfaces.

In an apparatus for producing atomized droplets for agricultural or horticultural purposes, the apparatus including spinning cone means and air blower means, the method comprising:

• producing controlled atomization droplets
• forming a fluid film on the spinning cone means and for moving the fluid film forward on the spinning cone means to produce a force vector tangential to the rotating axis of the spinning cone means,
• shearing the fluid film into the atomization droplets, and
• controlling projection of the atomization droplets in the same general direction for spraying on agricultural or horticultural spray surfaces.
