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.

1. An apparatus for thawing frozen food products, comprising: a tank having first and second ends, and a heating liquid located therein for thawing the food products, the tank defining a plurality of sections along a length of the tank;a spiral-shaped blade having a rotational axis and located inside the tank for conveying the food products through the plurality of sections in a direction from the first end of the tank toward the second end of the tank along the length of the tank;a temperature controlling system configured to independently control the temperature of the heating liquid in each of the plurality of sections of the tank; anda plurality of air supply sources arranged along the length of the tank, the plurality of air supply sources configured to pump air into the heating liquid,wherein the temperature controlling system includes a plurality of heat supplying units arranged along the length of the tank, each of the plurality of sections including at least one of the heat supplying units,wherein each of the heat supplying units is arranged along a bottom portion of the tank and each of the heat supplying units is configured to upwardly inject a heating agent into the heating liquid toward a surface level of the heating liquid in the tank at an angle generally perpendicular to the surface level of the heating liquid to provide a substantially equally distributed and uniform temperature in the heating liquid along the length of the tank, each of the heat supplying units having an upwardly extending nozzle extending into the tank from a common heat supplying pipe connected to a heat supplying liquid source,wherein the temperature of the heating agent injected into the heating liquid is greater than the temperature of the heating liquid,wherein the air supply sources are different from the heat supplying units, each of the plurality of sections including at least one of the air supply units, each of the air supply sources having an air supply nozzle extending upwardly into the bottom portion of the tank and oriented to provide an air flow generally perpendicular to and toward the surface level of the heating liquid in the tank,wherein pumping air into the heating liquid creates air bubbles in the heating liquid for providing a buoyant force to food products sunken at the bottom of the tank. 2. The apparatus according to claim 1, wherein the multiple heat supplying units are arranged at substantially equal length intervals below the tank. 3. The apparatus according to claim 2, wherein the temperature controlling system further comprises at least one thermometer arranged within at least one of the intervals for measuring the temperature of the heating liquid within the respective interval. 4. The apparatus according to claim 1, wherein the tank defines a lower bottom section and an upper section, the lower bottom section having a semi-circular cross-sectional shape with a diameter substantially the same as a diameter of the spiral-shaped blade such that a distal part of the spiral-shaped blade is located adjacent to the inner lower bottom section of the tank, and wherein two or more of said air supply sources are further distributed across the semi-circular cross-sectional shape of the lower bottom section of the tank. 5. The apparatus according to claim 4, wherein the multiple heat supplying units are arranged across a side of the lower bottom section of the tank where the spiral-shaped blade urges the food products toward the surface level of the heating liquid in the tank. 6. The apparatus according to claim 1, wherein the multiple air supply sources are integrally formed with the multiple nozzles of the heat supplying units. 7. The apparatus according to claim 1, wherein the temperature controlling system further comprises at least one thermometer arranged between the multiple heat supplying units for measuring the temperature of the heating liquid, said measured temperature serving as a control parameter for controlling the injection of the heating agent into the heating liquid. 8. The apparatus according to claim 1, wherein the tank defines a lower bottom section and an upper section, the lower bottom section having a semi-circular cross-sectional shape with a diameter substantially the same as a diameter of the spiral-shaped blade such that a distal part of the spiral-shaped blade is located adjacent to the inner lower bottom section of the tank, and wherein the upper section comprises at least one drain unit for allowing drainage of access liquid from the tank. 9. The apparatus according to claim 8, wherein the at least one drain unit is arranged for allowing the access liquid to be heated up and repeatedly injected into the tank. 10. The apparatus according to claim 9, further comprising a filter positioned between the at least one drain unit and a location where the access liquid is repeatedly injected into the tank. 11. The apparatus according to claim 1, wherein the apparatus further comprises an in-feed unit at the first end of the tank that is configured to feed the frozen food products into the first end of the tank, and wherein the apparatus further comprises a rotation motor and control unit configured to drive rotation of the spiral-shaped blade at a speed such that the frozen food products are thawed when they reach the second end of the tank. 12. The apparatus according to claim 1, wherein the apparatus further comprises an in-feed unit configured to feed the frozen food products along into the tank along at a side of the tank at least along a portion of the length of the tank. 13. The apparatus according to claim 1, wherein each of the heat supplying units is located proximate to at least one of the multiple air supply sources such that for each of the heat supplying units, a corresponding one of the air supply units injects air in parallel to the heating agent injected by the corresponding heat supplying unit toward the surface level of the heating liquid in the tank. 14. The apparatus according to claim 1, wherein the tank is divided into two or more sections, and the multiple heat supplying units arranged along the tank are configured to control a temperature within each of said sections independently.
