The Dynavox system utilizes a closed chamber to boil cork planks under high pressure. The pressure allows the cleaning solution temperature to maximize its effectiveness, while maintaining the stability of the corkwood. After the cleaning solution circulates through the corkwood slabs, it passes within a degasification tower where pressure differentials evacuate TCA and other volatile compounds.
Increased TCA extraction- Dynavox boiling is done under pressure at 105C to thoroughly penetrate the cork structure, volatize TCA, other anisoles and phenols.
TCA is constantly removed during boiling- The vapor containing TCA is removed by degasification through the one hour boiling cycle.
Shorter safer post boiling stabilization- Following the boiling process, cork planks are removed with an approximate 17% moisture content. This is a significant reduction in residual moisture.
Water filtration and continuous monitoring- The water is filtered through a 100 micron filtration system. The Dynavox system continuously measures the pH of the water to monitor residual tannin levels.
Complete extraction- Granules experienced prolonged direct contact with pressured steam volatizing the target compounds.
Continuous processing system- corks move from steaming directly to drying, eliminating the risk of microbial contamination.
Automated processing- continuous feed of granules through the SARA allows for high volume production.
M. A. Silva leveraged the latest technology in its development of the proprietary Maszone system; a cleansing stage for finished corks. The Maszone system uses ozone and hydrogen peroxide as primary treating agents to further reduce organic impurities and compounds off flavors.
Eliminates micro-organisms and their spores 3000 times faster than chlorine.
Faster processing- since ozone acts so quickly, finished corks absorb less solution which translates to shorter drying periods.
Inhibits TCA development- finished cork is sterile and free of microorganisms.
Enhances cork appearance- creates a cleaner and more uniform cork surface, allowing finer quality cork printing.
For Ultra-premium wine packaging, M. A. Silva’s proprietary OnebyOne® technology, inspects each natural cork individually to detect traces of TCA*. The powerful technology behind OnebyOne® was developed in collaboration with top European universities over a period of three years of R&D. The result is a fully automated process, utilizing the principles of gas phase spectroscopy.
Our newest innovative cleansing process uses the elastic memory of cork by expansion through dry
steam. This technology penetrates deep into the pores while maintaining the natural performance properties of the cork cellular structure. The result is maximized neutrality and TCA reduction in both natural corks and cork discs.
M. A. Silva’s new technology is designed to sterilize cork granules and remove TCA to non-detectable levels*. NEO® cork closures offer increased neutrality while supporting our ongoing commitment to sustainability, thus providing the highest quality technical cork solution.
Our proprietary process uses fluidized bed technology to maximize surface area exposure of the granules through a gaseous suspension to produce a gas-solid reaction. The result is the removal of TCA and other phenolic compounds that lead to off aromas. The consistency and natural physical-mechanical properties of cork are preserved.
