SCENARIO FOR THE SECTOR
Vine shoots’ transformation

From November to February, the pruning of vine plants produces considerable quantities of wood residues – long and mostly thin branches – called „vine shoots.”

Although they may seem worthless materials, there has been a progressive technological advance for the recovery and enhancement of these production waste in recent years. The vine shoots can be transformed into pellets in a righteous path of differentiation of energy resources.

Although they may seem worthless materials, there has been a progressive technological advance for the recovery and enhancement of these production waste in recent years.

The stages of vine shoot processing and transformation

Pellets are mainly obtained from the pruning of the vines. The process takes place first in the vineyards, collecting the waste and then passing through the dryers and compactors.

THE PROBLEM

The customer who turned to PNR Italia is a manufacturer of wine-making equipment.
The need was to prevent possible self-combustion fires on a belt that conducts the vine shoots in a dryer.
The dryer reaches an operating temperature between 100 and 120 ° C.
The conveyor belt is 11m long and 3m wide, and the pressure of the customer’s system is about 3.5 bar.

PNR ITALIA SOLUTION

The PNR Italia technical department designed a two manifolds system as long as the conveyor belt placed 70 cm above the belt.
Each manifold is equipped with 10 full cone spiral E nozzles, for a total of 20 nozzles throughout the system.
Each nozzle is placed at 1.10m from the other, except for the two at the ends of the manifold, located at 55cm respectively from the beginning and end of the manifold.

FOCUS ON THE PRODUCT

EBU 2156
FULL CONE NOZZLES

E full cone nozzle works on the impact principle, by the deflection of a water stream that impacts onto a spiral profiled surface which provides the desired spray angle. Their special design makes them virtually clog-free and produces a wider spray coverage than other nozzles for a given flow and pressure.
