PURPOSE: To make uniform the thickness of ice around an evaporator by sealing a water flow control device to the bottom surface of a cooling water tank on a bottom surface evaporator. CONSTITUTION: The icing surface of a bottom surface evaporator 2a is nearly a flat surface at initial icing but some portion of the icing surface does not ice at a lapse of time. Also, a water flow being generated by an agitation impeller blade 6 being rotated and driven by an agitator motor 4 results in turbulence in a direction along a bottom surface, thus enabling the shape of a lump of ice 12 adhering to an evaporator 2 to be indefinite. Although an ice thickness sensor 9 continues to operate normally, the lump of ice 12 grows at a pipe 8 to be cooled if operation continues for a long time, thus freezing a drink flowing in the pipe 8 to be cooled. Then, by providing a water flow control device 13 that has flat legs 13a at four corners and adheres to the bottom surface of a cooling water bath 1 on the bottom surface evaporator 2a of the cooling water bath 1, water flow that is agitated by an agitator motor 4 can be made constant and a lump of ice adhering to the evaporator can be formed in a stable shape.
