Abstract

A press for extracting fluid from fluid-containing matter so as to separate the fluid from the remaining matter, particularly for dejuicing of agricultural products, primarily fruit, includes a rotatably supported container, and at least one flexible membrane which can be actuated by exerting pressure thereon. The membrane is disposed in the container, and subdivides the container so as to define a pressure chamber and a press space therein. At least one wall surrounds the press space, and the pressure chamber has an inlet conduit and an outlet conduit for a pressure medium. Flexible drainage devices are located at least partly on the wall, and extend into the press space.
