Developing of Aging Wine Model by Dielectric Barrier Discharge (DBD) at Atmospheric Pressure

Abstract

Toxics in alcohol have been strongly negative affected to human life in large area, especially the alcohol with the huge poison inside like methanol, aldehyde, furfural, acidity$\dots$ It killed a thousand people, in developing countries particular and in the world general. The disadvantages of the currently state are the using treatment systems with low treatment efficiency, costly and unstable due to using microbiological, biochemistries, combining physical chemistry method. In this study, the treatment alcohol from laboratory using dielectric barrier discharge (DBD) at low temperature and at atmospheric pressure was designed and developed to solve the above disadvantages. An 800ml/h treatment system was completed and assembled. In order to prove the stability of the processing system, before and after treating, alcohol samples were collected and measured with methanol, aldehyde, furfural, acidity by the Quality Assurance and Testing Center. The treating duration and applied voltage were studied. The results show that with high discharge density, the toxics in alcohol rapidly increased due to oxidation reaction. However, at high applied voltage and long treating duration the treatment efficiency increased. The results also showed that treatment efficiency reached to 60-80% and match The Vietnamese Standard 7043: 2013 prepared by the TCVN/TC/F9 TCVN National Standardization Technical Committee, the Directorate for Standards and Quality, Ministry of Science and Technology
