Abstract: A density measuring device is described having: a housing, internally defining a first chamber, designed to contain a fluid the density of which it is desired to measure, and housing, in a measurement operating condition, a float, designed to be immersed in the fluid; and an electronic circuit that detects a value of the density as a function of a thrust sustained by the float due to the effect of the fluid; the housing further defines a second chamber, designed to contain a filling gas and to house the float in a cleaning operating condition of the float, distinct from the measurement operating condition, for removing gas bubbles and/or solid particles that have adhered to an outer surface of the float during the measurement operating condition.

Abstract: An automatic winemaking system is disclosed, which controls the execution of a winemaking process for the alcoholic fermentation of must obtained from a batch of grapes and the transformation thereof into wine in a winemaking tank. The system is provided with a database for storing winemaking data related to reference winemaking processes; a first processing unit for generating an optimized winemaking model, according to the winemaking data contained in the database, according to input data including characteristics of the batch of grapes and/or must; and a second processing unit for controlling and driving actuators acting on the winemaking tank according to the optimized winemaking model, so that winemaking process parameters are optimized for the features of the batch of grapes and/or must. The second processing unit is further capable of signaling fermentation kinetics faults and/or signaling alarms during the winemaking process.
