The Development of the Nano-Mist Sprayer and Its Application to Agriculture

摘要

In this paper, we describe the development of the nano-mist sprayer using the Venturi effect. This sprayer consists of AC or DC pump for Venturi effect, cylinder for causing Venturi effect, control circuit and separation plate. The particle diameter of this nano-mist sprayer is a few hundred nanometers or less. Furthermore, the particle size can be controlled by air pressure of the pump and shape of the separation plate. This sprayer can be applied to agriculture, medical, health care, etc. In this paper, we show an evaluation result of the mist particle diameter, firstly. Next, in order to confirm the usefulness of the sprayer, we apply to the agricultural field; the repellent spray was done by the fabricated sprayer. The experimental results are reported in this paper.
