  • Method of dejuicing harvested grapes
    Patent number: 5451415
    Abstract: A method for dejuicing grapes uses a dejuicer comprises a closed tank provided with a dejuicer grid and an inflatable membrane in the tank which is pressurized to force juice out of the harvested grapes through the grid. A conveyor in the tank remove the dejuicer grapes from the tank. Harvested grapes are placed in said tank and the juice is allowed to flow naturally. The inflatable membrane mounted in the tank is then pressurized to force out further juice through the grid and the juice is collected from the tank. The membrane is then depressurized and the tank is emptied by actuating the conveyor.

  • Screw press for grape crop
    Patent number: 4498382
    Abstract: The invention provides a helical screw press for processing grape crop in which a filter tube diverges from a predetermined section of its length in downstream direction such that the divergence enables the grapes to be released and prevents formation of an impermeable crust in the filtering tube thereby permitting total pressing and increased flow rate.
