Abstract
The present invention refers to a method and an equipment for the extraction of compounds from grapes by means of ultrasound in vinification processes generated through a sonoplate coupled to the walls of the pipe/duct through which the crushed grapes flow. During this extraction the transfer of phenols responsible for color from the solid portion (skin) to the liquid portion after crushing the grapes takes place as a consequence of the phenomenon known as cavitation, which allows the breaking of the skin cells and makes the phenolic compounds responsible for the color available to the liquid medium to be integrated in said liquid medium enhancing wine color.
