    摘要： Methods and apparatuses for loading, removing, accessing, positioning or preserving one or more items in a presence of dry ice are provided. The apparatus includes a tapered container that has a barrier-like structure which can partition the inner volume of the tapered container into an internal product storage volume and a dry icechamber. Each of the regions remain substantially undisturbed during handling, operation, use and transport of the tapered container. Methods for selectively introducing dry ice into the dry ice chamber of the tapered container and engaging the barrier-like structure within the tapered container can be achieved with a novel guiding assembly apparatus. The methods and apparatuses are particularly useful when loading and retrieving one or more items in the presence of dry ice for tapered containers that have single restrictive access openings and/or other characteristics which make access and handling difficult.

    摘要： A cyclone refrigeration device comprises a cylindrical portion 1, an exhaust pipe 3, a cooling portion 4 with a cavity 4a communicating with an interior space 1b of the cylindrical portion, a refrigerant inflow pipe 5 and a decompression unit 6. A liquid-phase refrigerant condensed under high pressure is supplied into the refrigerant inflow pipe and decompressed into a solid-gas two-phase refrigerant by the decompression unit, and the solid-gas two-phase refrigerant flows downward into the interior space of the cylindrical portion while forming a first vortex flow and separating into a solid-phase refrigerant and a gas-phase refrigerant. The solid-phase refrigerant deposits in the cavity and the gas-phase refrigerant forms a second vortex flow rising from the bottom of the cavity through the inside space of the first vortex flow to flow out through the exhaust pipe. A circulation pipeline for circulating fluid to be cooled 7a, 7b extends through the cavity. A heat exchanger 8 is provided in a portion of the circulation pipeline which is located within the cavity and exchanges heat between the solid-phase refrigerant Sand the fluid to be cooled. A pump 10 circulates the fluid to be cooled.
