Abstract
The result of the measuring laboratory tests indicated that the power requirement for developed single and two rotary cage atomizers. where the maximum power requirement for single and two rotary cage spryer atomizers were 29.76 W and 55.2 W at rotational speed 3600 rpm respectively. Also, increasing the rotational speed tends to increase the power requirements for developed electric rotary cage atomizer. The increasing of out let distance gave the low air velocity under all test rotational speed conditions. The maximum air velocity was recorded 5.3 ms-1 at out let distance 20 cm and rotational speed 3600 rpm. As well as the mean value of air velocity was 4.3 ms-1 at out let distance 60 cm. This value is the indicator of the velocity droplet size produced from the developed electric rotary cage atomizer into the target or orchards. It could be able to operate the electric rotary cage atomizer to produce different droplet velocities. As well as it is essay to control the droplets and air velocities by changing the power sources of the rotary cage atomizer using the manufactured control unit. Also, their maintenance will be able and very chip compared with hydraulic rotary cage atomizer.
