The invention relates to the field of milk storage and transportation, in particular to a double-barrel type milk storage quick-cooling machine. The double-barrel type milk storage quick-cooling machine comprises a machine shell. An inner container for containing milk is arranged in the machine shell. A cold storage layer is arranged on the periphery of the inner container. An exchange pipe is vertically arranged at the bottom end of the inner container. The top end of the exchange pipe is closed. A certain distance is formed between the top end of the exchange pipe and the top end of the inner container. Vent holes are formed in the side wall of the exchange pipe, supporting rods are horizontally arranged on the side wall of the exchange pipe, the supporting rods are sleeved with stirring blades, and the stirring blades are rotationally connected with the supporting rods. The milk in a tank shakes in the transportation process, so that the milk automatically achieves the stirring function, energy is saved, and operation is convenient.
