The invention provides an inner-outer double-layer circulation type drying and refrigerating integrated device. The inner-outer double-layer circulation type drying and refrigerating integrated deviceis composed of a drying and refrigerating outer circulation loop and a regeneration inner circulation loop. Heat transfer between the two loops is carried out through a cooling chamber and a heatingchamber. Air in the drying and refrigerating outer circulation is heated through the heating chamber, the air in the drying and refrigerating outer circulation is cooled through the cooling chamber, the air temperature is rapidly increased and decreased, and the air is introduced into a drying house and a refrigeration house. A regenerator carries out regeneration treatment on a gas state and a liquid state of refrigerating fluid. Compared with an existing drying and refrigerating device, drying and refrigerating can be carried out simultaneously in the same system, the inner-outer double-layer circulation is adopted, dried high-temperature waste gas is fully utilized, the regenerator is additionally arranged in the inner circulation, energy loss is reduced, and the efficiency of the system is effectively improved.
