Scenarios applicable to this industry:

Transformation of vine branches.Pruning grape plants from November to February produces large amounts of woody residue — long, thin branches called “vine branches.”

Whilst they may seem worthless, the recycling and adding value of these production wastes has been making incremental technological advances in recent years. Grape vine branches can be converted into wood pellets in the right way for differentiated utilization of different energy resources.

Stages of vine branch treatment and transformation:

The grains are mainly obtained from the pruning of the grapes. The process takes place first in the vineyard, where the waste is collected and then processed through dryers and compactors.

Harvest stage:

Vines are collected from the ground by special shredders that separate the sawdust from the grass and leaves;

Drying phase:

The drying phase can be carried out naturally for about two months, or the processing time can be significantly shortened by special machinery;

Crushing stage:

Once dry, convert the material into fine wood chips, which are then converted into pellets;

Convert to particles:

Wood chips (without other binders) are compressed into pellets at special temperatures (40 to 80 degrees Celsius).

Question:

HAPOO’s customers are wine equipment manufacturers.
Their need was to prevent possible spontaneous combustion accidents on the conveyor belt of the dryer.
The dryer reaches an operating temperature of 100 to 120 degrees Celsius.
The conveyor belt has a length of 11 meters and a width of 3 meters, and the pressure in the customer’s system is about 3.5 bar.

HAPOO solution:

HAPOO technical department designed a double pipe system with the same length as the conveyor belt, located 70 cm above the conveyor belt.

Each pipe is equipped with 10 full cone nozzles, for a total of 20 nozzles spread throughout the system.
Each nozzle was 1.10 m from the other nozzles, except for two nozzles located at the ends of the pipe, which were 55 cm from the beginning and end of the pipe, respectively.

Full Cone Nozzle:

Full cone nozzles work by deflecting the water stream so that it hits a helical surface to provide the desired spray angle. Their special design allows them to be virtually non-clogging and produce wider spray coverage than other nozzles for a given flow and pressure.

HAPOO’s technical solutions can effectively prevent possible spontaneous combustion on the dryer conveyor belt for wine equipment manufacturers. Our multi-pipe system and full-cone nozzle provide customers with safe and reliable fire prevention measures to ensure efficient and smooth production process.
