Ultrasonic atomizer application for Low Cost Aeroponic Chambers (LCAC): A review

Abstract

Technology of ultrasonic atomization has been proven effective at creating droplets with specific physical and functional properties. Applications of this technology include drying liquids, medical nebulizers for inhalation therapy, surface coating, and encapsulation of materials in particles for therapeutic medicine, nutritional food, energy production and imaging. Parameters studies in this literature reviews are related with correlation of frequency values, droplet size, and flow rate of liquid, as well as the temperature resulting from the breakdown of molecules through the transducer droplet particle size and evaporation rate also need to be considered because it is related to the effectiveness of uptake nutrients in the roots. This article provides an overview of the primary mechanisms arising from ultrasonic responsible for the formation of these materials, highlighting examples that show promise particularly in the development of aeroponic system and bioproducts.
