Abstract: A quick-kill system by which objects to be quickly killed can be kept in a fresher state. The quick-kill system includes: a quick-kill device that cools a fish with ice slurry at a first temperature (?21° C.) to bring the temperature of the fish to a second temperature (?1° C. to ?2° C.) lower than the lower limit of the temperature at which the fish can live (0° C. to 2° C.), while keeping at least the center part of the fish in a refrigerated state; and a transport part that transports the fish, wherein the transport part immerses the fish into the quick-kill device while transporting thereof, and, when the time has reached a predetermined immersion time for bringing the temperature of the fish to the second temperature, pulls the fish out of the ice slurry.

Abstract: Provided is an ice-making device that can be easily miniaturized. The ice-making device includes: a freezing tank 12 that stores brine; and a flake ice making part 15 arranged inside the freezing tank 12 and capable of being immersed in the brine Ws, wherein the flake ice making part 15 includes: a disc part 26 that causes a refrigerant, which is supplied from a freezing machine 14, to circulate therein, the disc part 26 having plate surfaces 26a, 26b that generate ice of the brine Ws; a nozzle part 41 that provides a flow of the brine Ws to the plate surfaces 26a, 26b; and a sweeping part 23 that is displaced with respect to the plate surfaces 26a, 26b to separate the ice generated on the plate surfaces 26a, 26b from the plate surfaces 26a, 26b.
