摘要

The unit has a heat-insulated casing (1) about half full of liquid nitrogen (LN2). A rotatable transport platform (2) and a corresponding hinged ejection platform (3) are arranged in the casing with their rotation axes above the fluid level (4). A supply opening (5) corresponding to the transport platform slopes downwards. An ejection opening (6) corresponding to the ejection platform slopes downwards. A semicircular fluid-permeable inner wall (7) is arranged in the lower area of the transport platform.
