The invention discloses a small packaged beer and beverage rapid cooling device. The device comprises a refrigerating unit, a cooling tank and an electrical control part, wherein a water circulation system is arranged between the refrigerating unit and the cooling tank, the evaporator of the refrigerating unit is connected with the cooling tank through a water inlet pipe; and after cold water performs heat transfer in the cooling tank, the obtained water flows back to the evaporator of the refrigerating unit through a return pipe and a circulating pump. The invention utilizes the refrigeration technology and heat conduction theory, uses the refrigerating medium for continuous cooling and adopts the types of flow and direct contact to fast cool beverage. Compared with the common air-cooling method, the method of the invention has the advantages of fast cooling rate, large yield, adjustable capacity, simple operation, low operating cost, wide application range, small floor space, light weight and the like.
