An arrangement for pressing liquid-containing raw materials, the arrangement comprising:

• an inherently rigid support framework disposed to be rotatable about an axis of rotation;
• a press container composed of a pressure-resistant flexible plastics material, said press container being accommodated in said rigid support framework and being rotatable together with said rigid support framework about the axis of rotation;
• a press membrane dividing an interior of said press container into a pressure medium chamber and a pressing medium chamber;
• said press container being formed with a filling and emptying opening which is closable in a pressure-tight manner and which is configured for receiving the liquid-containing raw materials into said pressing medium chamber;
• and
• at least one drainage element arranged in said pressing medium chamber, said at least one drainage element having an interior communicating with a juice outlet of said press container for delivering liquid juice to a juice collecting container during a pressing operation.
