The invention relates to the field of supercritical drying, and discloses a supercritical carbon dioxide drying device and application thereof and a supercritical carbon dioxide drying method.The device comprises a supercritical treatment unit, a drying unit and a separation unit which are sequentially communicated through pipelines, and the drying unit comprises 3-12 drying kettles arranged in parallel; the supercritical treatment unit is used for performing supercritical treatment on the condensed carbon dioxide to obtain treated carbon dioxide; the drying unit is used for enabling the treated carbon dioxide to be in contact with a to-be-dried material for drying treatment to obtain an effluent I; and the separation unit is used for separating the effluent I to obtain carbon dioxide capable of being recycled and an effluent II. The supercritical carbon dioxide drying device and the supercritical carbon dioxide drying method provided by the invention have relatively high drying efficiency and relatively low
