spruzzi

Spruzzi is the Italian term for droplets or jets of liquid produced when a liquid is sprayed. It can refer to the droplets themselves or to the act of spraying, and it is commonly used in contexts ranging from agriculture to industrial coating.

Spruzzi form through atomization, a process in which liquid is broken into fine droplets by forces such as pressure, flow through a nozzle, or interaction with air. The resulting droplet size distribution depends on liquid properties (viscosity and surface tension), operating pressure, nozzle design, and the surrounding airflow. In practice, sprays are described as fine, medium, or coarse, reflecting their typical droplet ranges and penetration characteristics.

Applications of spruzzi span multiple sectors. In agriculture, spraying delivers pesticides or fertilizers to plant surfaces. In industry and consumer care, sprays are used for painting, coating, cleaning, disinfection, cooling, and fragrance dispersion. Medical devices such as nebulizers generate spruzzi small enough to reach the respiratory tract, used for drug delivery. The choice of nozzle type, spray angle, and operating pressure influences coverage, adhesion, and efficiency in these applications.

Measurement and safety considerations focus on controlling droplet size distribution, spray coverage, and potential environmental impact. Improperly controlled spruzzi can drift away from targets, leading to exposure risks or waste. Proper nozzle selection, system calibration, and adherence to safety guidelines are essential to maximize effectiveness while minimizing risks.
