Development of equipment for the spraying of phytosanitary products by means of compressed air and water spraying.
HUMIFITO® is a spraying system designed and manufactured by Novedades Agrícolas S.A., based on the spraying process using a combination of compressed air and water.
Year of project: 2004
How does it work in greenhouse cultivation?
The compressed air is projected against the water at a very high speed, breaking the water droplets and causing their atomization. The size thus obtained produces a mist that remains in suspension, so that the application covers the entire plant canopy, the top and underside of the leaves, stems and fruits.
Another application of the system is to serve as a humidification system for the correction of low ambient humidity and as a cooling system.
How is it designed?
The most important element of the installation are the sprayers, HUMIFITO® nozzles, which allow the use of abrasive, corrosive and solids in suspension solutions.
They have been designed and manufactured for the application of any phytosanitary product, or compatible mixtures of existing products in the market.
Where is it installed in the Greenhouse?
The Humifito nozzle is installed with a suitable frame in a regular way covering the total surface of the greenhouse, at a height higher than the crop’s trellising system.
A network of ducts supplies the required compressed air flow. A second network, in parallel layout, distributes the flow of the phytosanitary liquid through self-compensating drippers, installed with the same spacing as the spray nozzle.
The system allows spraying the different solutions developed for plant protection.
How to manage this system?
A series of solenoid valves installed in the air and phytosanitary liquid distribution pipes are activated by a programmer controller to carry out the application or spraying automatically.
This controller manages the volume of liquid to be sprayed in a given area, as well as the cleaning process of the distribution network, so that the application is completely localized in the treatment area or sector.
The process can be carried out by means of timers, or by expenditure control, programmable by sector. The controller allows the use of HUMIFITO® as a humidification system, remotely operated by a climate controller, as well as, it can be part of the management as it can be used for water spraying control.
