Abstract: The present disclosure provides a supercritical fluid-drying apparatus and a method for drying gel. The apparatus includes a circulation fluid storage tank, a circulation compressor with a feed inlet in communication with the circulation fluid storage tank, a drying unit with a fluid inlet in communication with a discharge outlet of the circulation compressor, a separation unit with a fluid inlet in communication with a fluid outlet of the drying unit, an expander disposed between the drying unit and the separation unit, and a heating-medium storage tank in communication with a first heat exchanger inlet of the circulation compressor and a heating-medium outlet of the drying unit. A first heat exchanger outlet of the circulation compressor is in communication with a heating-medium inlet of the drying unit.
