The Dynavox® technology allows the sterilisation and vaporisation of the raw material.
It is used in the production process of all cork stoppers – natural and technical – produced and marketed by MASILVA.
All raw materials are subject to intense steam and pressure and submerged in clean water, through our Dynavox® system, so as to remove any unwanted substances from the innermost part of the cork. The process guarantees the elimination of microorganisms without using chemicals.
Using the Dynavox® technology, anisoles such as TCA are reduced, along with other odour-causing compounds, as well as tannins and anisole precursor phenols, increasing the thickness and elasticity of the cork.This process leaves the cork with a moisture content that allows it to be worked immediately, and there are no favourable conditions for the possible development of microorganisms that could be harmful to the raw material.
Advantages of the Dynavox® technology
INCREASES TCA-REMOVING ABILITY
Boiling takes place under pressure at 105ºC, penetrating the cork structure, dragging off and vaporising the TCA and other anisoles and phenols;
TCA IS CONSTANTLY REMOVED DURING BOILING
The steam containing TCA is removed by degasification during a one-hour boiling cycle;
SHORTER AND SAFER CORK STABILISATION PERIOD
After the boiling process, cork planks are removed with around 17% moisture content. This significant reduction in residual humidity allows for the stabilisation period to be shortened from two weeks to two days;
WATER FILTRATION AND CONTINUOUS MONITORING
Water is filtered using a 100-micron filtration system. The Dynavox ® system continuously measures the pH of water, to monitor the level of tannins.
