Abstract: The present invention relates to a device for continuous monitoring and improved automatic control of temperature, and of aeration-oxygenation, of the process of alcoholic fermentation in wine by means of acoustic emission techniques (D1), of the type of devices that incorporate means for tracking and controlling alcoholic fermentation in a self-emptying fermentation tank (0), and that mainly consists of: a. an instrumentation subsystem (1); b. an acoustic emission instrumentation subsystem (2); c. a gas processing and storage subsystem for the gases of air, CO2, N2 or O2 (3); d. a control subsystem (4); and a method (P1) that uses the system (D1).

Abstract: The invention relates to a self-cleaning homogeneous mixer-bleeder system composed of a set of screens and a bleed manifold (1), in particular for the production of must by pellicular maceration, of the type incorporated in a wine maceration tank (0) and having mainly: a. a bleed system (10) containing a bleed manifold (107) and a set of perforated side bleed screens (102); b. an inerting valve (11); c. a CO2 system (12).
