<p>TITLE OF INVENTION A METHOD FOR INSTANTLY KILLING AND COOLING FISH, AND AN APPARATUS FOR CARRYING OUT THIS METHOD The method of killing and preserving fish in a fresh stateproposed by this invention is a two stage procedure. In the primary or instant cooling stage, fish are killed instantly by the shock of emersion in a rapid cooling fluid. This fluid subjects the surface layer of each fish to a temperature below that at which they will be stored. In the secondary or storage stage, individual fish are either passively cooled on the inside by their low temperature surface layer, or else they are cooled inside and out by external means. The fish execution and cooling apparatus proposed by this invention to realize the above mentioned method is comprised of the following: a rapid cooling hopper to deliver fish into the system, a primary rapid cooling tank to instantly kill fish, and a device connected to the primary rapid cooling tank to discharge fish to the secondary stage cold storage tank. Live fish are introduced to the system through the rapid cooling hopper, killed by the shock of instant cooling in the primary rapid cooling tank, and subsequently delivered to the secondary stage cold storage tank by the discharge device.</p> |
