Method and apparatus for tempering of meat, tempered meat treated by the method, and refrigerated meat storage
InactiveUS20100075016A1Suppressing transpirationReduce the temperatureMilk preservationWort preparationCold airIce storage
A tempering treatment method whereby the temperature of meat, which involves carcass prepared by slaughtering cattle or poultry and sterilizing and washing, is lowered as close to the ice storage temperature as possible to prevent a temperature rise caused by the actions of enzymes contained within the meat before transporting the meant to a refrigerated storage, which comprises surface-freezing the meat by blowing a cold air stream at about −20 to about −40° C. to the meant before conducting the tempering treatment, thus allowing the generation of freezing latent heat in the subcutaneous part owing to the surface-freezing (freezing the subcutaneous tissue), and then rapidly lowering the core temperature inside the meat due to the latent heat released at the melting of the freezing latent heat to thereby conduct the tempering treatment at a temperature of 0 to +15° C.

Process for chilling animal carcasses
InactiveUS6845624B2Inhibit deteriorationDelay water lossLighting and heating apparatusCarcasses chillingEngineeringCold store
A process of cooling animal carcasses from a kill temperature to a temperature at which deterioration is substantially prevented comprises circulation of refrigerated air over the carcass to freeze an outer of the carcass, followed by application of water to the carcass to form a sufficiently continuous layer of ice on the carcass. Preferably, the carcass is chilled by a multi-stage quick chill process in which the carcass is exposed to super-cooled, high velocity air. Immediately before or immediately after formation of the ice layer, the carcass is transferred to a refrigerated chamber to allow the interior and exterior of the carcass to equilibrate to the temperature at which deterioration is substantially prevented. The inventors have found that this process provides reduced moisture loss and reduced bacterial loading over prior art processes in which water is applied to the carcass during the quick chill process.

Rocker Chiller with Serpentine Carcass Flow
A rocker chiller 10 includes a tank 12 with a dasher assembly 26 that oscillates across the curved bottom wall of the tank. A series of central deflectors 40 are positioned at intervals along the length of the tank and another series of side deflectors 46 are mounted at intervals along the upwardly extending side walls 16 and 18 of the tank. The side deflectors are offset longitudinally with respect to the central deflectors. The offset relationship of the side deflectors and central deflectors creates serpentine paths through the elongated tank on both sides of the tank that require the carcasses to move through more of the heat exchanging liquid and which reduces the tendency of carcasses passing each other.

Three-Paddle Rocker Chiller
A rocker-type poultry chiller, including a tank for receiving poultry carcasses and holding chilled water, an axle mounted in the tank, a main paddle connected to the axle, and a side paddle connected to the axle. The oscillation of the main paddle and the side paddle urges the carcasses upwardly and laterally, which contributes to the cooling of the carcasses as a result of their thorough contact in the chilled water. The movement of the paddles also gently massages the carcasses by gently bumping them against the paddle blades and the wall of the tank. The repeated compression of the carcasses tends to tenderize the meat. The side paddles ensure more predictable and consistent contact between the paddles and all of the carcasses, which causes more agitation of the carcasses and more effective washing of the carcasses.
