ABSTRACT:
A juice press as used in the production of wine for removing liquids from solids, having a horizontally positionable press frame that allows a vertical press mechanism to be rolled to a first position for interference-free loading of a press basket with material to be pressed, and then rolled to a second operating position located over the press basket. The press basket has a liquid channeling plate having an arrangement of holes and channels that creates a perimeter seal along a circumference at the bottom of a loaded press basket. The liquid channeling plate traps naturally occurring sludge along the circumference bottom and allows for efficient evacuation of extracted juice from the bottom of the basket as the press mechanism is operated. In one embodiment, the press frame is configured with a hydraulic press basket lift that raises and holds the press basket after a press operation is completed and allows the press mechanism to be used to eject a disk of compressed solids from the bottom of the raised press basket.
