SCENARIO FOR THE SECTOR
Tannins in the wine sector

Tannin is one of the four characteristics – in addition to acidity, alcohol and residual sugars – that make wines resistant to aging.

The tannin that we find naturally in the wine comes from its extraction from the grape pips during pressing or maceration. A part of the tannins is given to the wine also by wooden barrels where it is aged.

Tannins are also available in the form of liquid or powder additives as well, to be added to wine in its various production phases. The purposes of using this kind of additives are many, from the stabilization of the wine itself to the elimination of sulfur compounds with an unpleasant odor, up to the control of bacterial activity and molds.

SOLUTIONS FOR THE WINE-MAKING INDUSTRY

Tannin is one of the four characteristics – in addition to acidity, alcohol and residual sugars – that make wines resistant to aging.

 

Tannins extraction – industrial process

What are the phases of extraction of tannin from wood?

THE PROBLEM

The customer who contacted us needed to wash the inside and outside of a machine for the treatment of tannin powders in the wine sector.

PNR SOLUTION

The Technical Department of PNR has developed a system of manifolds with nozzles and washing heads that could wash a mesh basket for the treatment of tannin powders, which rotates along its longitudinal axis inside a box.

On the upper part of the manifold, placed inside the box and around the basket, there are 9 high impact nozzles K. Their jet is directed on the outside of the basket.

8 UBC rotating washing heads have been installed in the two C-brackets that support the manifolds structure, 4 per side of which 2 at the bottom and 2 at the top.
The action of the washing heads is aimed at cleaning the residues removed from the K nozzles, in order to keep the inside of the box clean.

At the intersection between the C-shaped manifolds and the longitudinal manifold, three-way ball valves have been installed, which manage the flow of the liquid, directing it first to the flat jet nozzles and then to the washing heads.

ADVANTAGES 

Before our intervention, the washing process was carried out manually and using high pressure washers, resulting in high costs and extensive use of water resources.
The solution proposed by PNR allows to improve the washing process, optimizing costs and times.
