This utility model relates to the technical field of raw food refrigeration and preservation boxes, and more particularly to a low-temperature refrigeration and preservation box for raw red-eyed trout products. The box includes a preservation box with a low-temperature shelf at the bottom, and placement shelves stacked on top of the low-temperature shelf. Symmetrical guide grooves are formed on the inner walls of both sides of the preservation box. Guide strips adapted to the guide grooves are installed on both sides of the low-temperature shelf and the placement shelves. A flow channel is formed from the center to both sides on the bottom wall of the placement shelves, and a collection channel corresponding to the flow channel is formed on the inner walls of both sides of the preservation box. A refrigerant is placed inside the low-temperature shelf, and a temperature equalization mechanism is provided on the low-temperature shelf to transfer the low temperature from the bottom layer to the top layer. When the refrigerant cools and produces condensation, the condensation flows through the guide grooves into the collection channel and then to the bottom of the preservation box. The condensation is absorbed by highly absorbent cotton, thus preventing condensation from accumulating in the placement shelves and causing the raw fish to spoil.
