A plant for the grapes cryo-maceration that uses the direct injection of CO2 has been studied. Such types of plants allow to obtain wines of high quality, however sometimes because of a bad use of them, it is possible that can rise serious drawbacks. Therefore such search is aimed to study the most critical part of such plant, that is the zone where the injection of the CO2 happens, that is situated in proximity of a divergent tube. After having determined the geometric characteristics of the materials and the thermodynamic characteristics of the fluids (CO2 and mashed grape) a numerical simulation of the thermodynamic exchange between the two considered fluids has been performed, and they have been examined some characteristic conditions obtaining helpful data results to be used for the optimization of the use of the considered plant.

Abstract

A plant for the grapes cryo-maceration that uses the direct injection of CO2 has been studied. Such types of plants allow to obtain wines of high quality, however sometimes because of a bad use of them, it is possible that can rise serious drawbacks. Therefore such search is aimed to study the most critical part of such plant, that is the zone where the injection of the CO2 happens, that is situated in proximity of a divergent tube. After having determined the geometric characteristics of the materials and the thermodynamic characteristics of the fluids (CO2 and mashed grape) a numerical simulation of the thermodynamic exchange between the two considered fluids has been performed, and they have been examined some characteristic conditions obtaining helpful data results to be used for the optimization of the use of the considered plant.
