ABSTRACT:
A press for pressing out substances containing liquids, especially agricultural and chemical products, includes a closed container whose inner area is divided by at least one press membrane into a pressure medium chamber and a pressing medium chamber. A fill/discharge opening, sealable by a lid, is disposed in the casing and is associated with a juice run-off located in the pressing medium chamber. Flexible or elastic liquid-permeable drainage elements are also disposed in the inner area of the container for removing juice. The drainage elements include at least one support element and a flexible tube disposed therearound and are of a juice-permeable material. The drainage elements are configured as single-pieced components and are detachably received on the container by holding devices, which are disposed on both sides of the container, each drainage element being able to be removed as a component from the inner area of the container.
