An apparatus for thawing or cooling food products includes a tank adapted to be at least partly filled with a liquid. A spiral shaped blade extends between a first end and a second end of the tank, where the spiral shaped blade is mounted to a rotation axis which operates rotational movement of the spiral shaped bladed and thus the conveying of the food products from the first end towards the second end. A temperature controlling system is provided and adapted to control the temperature of the liquid by arranging multiple heat supplying units along the tank for injecting heating or cooling agents into the liquid so as to provide a substantial temperature distribution into the thawing liquid during the thawing or cooling of the food products.

The invention relates to a method for cooling slaughtered poultry, including the steps of: positioning the poultry with spread legs, with the abdominal cavity upward and oriented in the transporting direction of the poultry; and transporting the positioned poultry through cooled flowing water, wherein the transporting direction of the poultry is opposed to the flow direction of the water such that water flows around and through the poultry from the abdominal cavity toward the neck cavity. The present invention also relates to an installation including: a positioner for receiving the slaughtered poultry with the abdominal cavity oriented upward in the transporting direction; a transporter for transporting the positioned poultry; and a cooler including a container for cooled and flowing water, wherein the flow direction is opposed to the transporting direction, and to the treated poultry.

A method of cooling a dressed carcass of a slaughtered animal halved along the backbone thereof while transferring the dressed carcass in a cooling chamber is provided, with which reduction in process yield in the cooling process due to evaporation of water from the dressed carcass is suppressed to a minimum, meat juice dripping together with water does not occur when cutting the dressed carcass, the cooling period of time is reduced, energy is saved in cooling process, initial cost is reduced, and productivity is improved. The dressed carcass is cooled while transferring in the cooling chamber in a hanged attitude along the transport route T, whereby a plurality of partitioned spaces are provided in the cooling chamber 1 such that they are arranged along said transport route with a relatively small distance between them in a zone where the surface of the dressed carcass is cooled quickly and with a relatively large distance between them in a zone where surface temperature of the dressed carcass has approached the temperature of the cooling chamber and the dressed carcass is cooled slowly, and water is added to the surface of the dressed carcass while blasting cold air on to the dressed carcass in the partitioned spaces.

The invention discloses a production method of cooling and keeping fresh beef. The production method of cooling fresh beef includes slaughtering, bleeding, peeling, and removing viscera. After the carcass passes the quarantine inspection, it is rinsed with water; The carcass is deboned, divided and trimmed, and then vacuum-packed, then hot-soaked and cold-soaked, and then placed in an environment of -2 to 2°C for storage. Compared with the prior art, the fresh-keeping beef obtained by the present invention has better safety and sanitation, and longer preservation period.

A tempering treatment method whereby the temperature of meat, which involves a 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 meat 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 meat 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.

The invention provides a rolling cage type washing and pre-cooling machine, relating to a device for washing or cooling poultry carcasses when poultries are slaughtered. The rolling cage type washing and pre-cooling machine is designed to mainly solve the problems of the existing spiral pre-cooling machine that the cooling effect of the poultry carcasses is poor and the poultry carcasses are damaged. The rolling cage type washing and pre-cooling machine comprises a main machine body, wherein the main machine body is internally provided with a rolling cage; a spiral sheet is arranged on the inner wall of the rolling cage; a roller is arranged in the main machine body through a roller bracket; the rolling cage is provided with a rolling groove; the rolling groove is placed on the roller; the periphery of the rolling cage is provided with a gear ring; the main machine body is provided with a motor speed-reducing machine; a gear on a power output shaft of the motor speed-reducing machine is engaged with the gear ring arranged on the periphery of the rolling cage; an inlet is arranged at one end of the rolling cage, and an outlet is arranged at the other end of the rolling cage; the rolling cage is internally provided with an evaporator; the main machine body is fixedly provided with two evaporator collecting pipes; the evaporator in the rolling cage is communicated with the two evaporator collecting pipes on the main machine body; an air pump is additionally arranged on the main machine body; and an air outlet of the air pump is provided with an air pipe communicated with an air pipe in the main machine body. The rolling cage type washing and pre-cooling machine has the advantages of good washing and cooling effects and no damages to the poultry carcasses.

A method for processing meat along a meat processing line. The method includes removing viscera from a carcass, accumulating the carcass along a dead rail stack of the meat processing line, washing the carcass, and inspecting the carcass at an inspection station following the act of washing the carcass.

A chiller bath includes a tank for holding a volume of chiller water; a dosing system for dosing a first solution and a second solution into the chiller water, arranged to create a plurality of zones within the volume of water, wherein each zone has a higher concentration of either the first or the second solution than surrounding portions of the volume of water; and a meat or poultry immersion arrangement for immersing and moving carcasses in the chiller water. A method for reducing bacterial load on meat or poultry includes generating a plurality of zones within a chiller bath containing water by dosing a source of alkalinity and antimicrobial into the water, wherein the plurality of zones comprises at least one alkaline zone with a pH above 8.5, and at least one antimicrobial zone with pH below 8.5; and submersing meat or poultry in the bath. The zones can also be generated using spray nozzles in a meat or poultry operation.

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.

A poultry cooler includes a tank and an auger rotatably held within the tank. The auger includes a first auger section and a second auger section. The first auger section includes a first auger shaft and a first auger blade. The first auger blade includes a first helical portion on the first auger shaft and a first blade extension extending away from the first helical portion. The second auger section includes a second auger shaft coupled to the first auger shaft and a second auger blade. The second auger blade includes a second helical portion on the second auger shaft and a second blade extension extending away from the second helical portion. The cooler includes a hanger bearing assembly between the first and second auger sections and extending to an upper portion of the tank.
