Apparatus and method for separating substances of different flowability that are mixed together

An apparatus configured to separate substances of different flowability that are mixed together, the apparatus comprising:

• a frame structure;
• a hollow drum, wherein:
• the hollow drum is driven in rotation,
• the hollow drum is mounted on the frame structure, and
• the hollow drum comprises a perforated circumferential surface and at least one end side, wherein the at least one end side is at least partially open;
• an endless press belt driven in rotation, wherein:
• the endless press belt is wrapped around a part of the perforated circumferential surface of the hollow drum, and
• the endless press belt can be pressed from outside against the hollow drum;
• a product intake wedge formed by the endless press belt and the hollow drum, wherein:
• the product intake wedge is configured to guide a product flow into the apparatus, and
• the product flow comprises material to be pressed into a space between the hollow drum and the endless press belt in an inlet region of the product flow;
• a support apparatus for the press belt, the support apparatus comprising at least one support element, wherein the at least one support element is located on a side of the press belt opposite the hollow drum;
• a discharging device configured to discharge separation material pressed through the perforated circumferential surface, wherein:
• the discharging device comprises a stripping element and/or an ejection screw,
• the separation material is pressed into a hollow space of the hollow drum, and
• the separation material is pressed from the at least one end side of the hollow drum;
• and
• a cooling device, wherein the cooling device is configured to cool the separation material during processing with a cryogenic cooling medium and is assigned to the hollow drum.
