Vit.En. Nebulizer

The leaf application are performed with a prototype ideated from the Vit.En’s technicians and made from the firm Dragone. This equipment designed for parcel type tests, it is able to distribute 14 different formulations simultaneously. It is compose by 14 tanks in inox they can contained 8 L (A) inside we put the mixture of water and active ingredient after pre-mixing in a glass container.


The main tanks, put under pressure during the work phase, are connected to as many solenoid valves (B) that impose the opening and closeting. This operation requires a few fractions of a second, sufficient to change the product between one parcel and the other without stopping the progress of the machine, thus ensuring a very uniform distribution. The ground-based experimenter controls these solenoid valves with a palmtop computer connected to them via Bluetooth. (C)


Each tank has an independent circuit that connects it to a series of nozzles suitable for the distribution of the mixture on the vegetation (D; E), avoiding the possibility of contact between different products. A series of electrically powered fans cause a vortex of air which favors the penetration of the drops into the vegetation.
A semi-automatic washing system cleans the entire circuit at the end of each individual application. This equipment allows, set the feed speed, the operating pressure and the nozzle size (F), an absolutely precise and uniform distribution at all times of the application, as well as reducing working times and the possibility of error compared to manual applications.


Backpack sprayer and shoulder pump.

For vineyards where it is not possible to use the Vit.En. the treatment with the Turbine Super pneumatic shoulder atomizer is carried out manually. It combines the penetration capacity within the vegetation with a limited amount of water per hectare (G).

With the shoulder pump, on the other hand, the liquid is pressurized by a pump inside the tank which conveys the product to the outlet nozzles. The latter, using a anti-drift mirror nozzle, is also used for the application of herbicides and shooters (H).
