Regulating the temperature of the grapes uses the immersion principle and dynamic cross-flow drainage: the harvest is soaked in a bath of heat-transfer fluid and drained by drums allowing the transfer.
The processing chain is entirely controlled by a programmable logic controller (PLC), which regulates the temperature when the grapes leave the heating chamber depending on the type of vinification chosen (hot pre-fermentation maceration: 72°C, Flash Detente thermovinification: 85°C).
A simple and intuitive touchscreen enables the operator to control the various operating parameters (temperatures, maceration time) and informs the operator of the Gulfstream status.
