Disclosed is a system for providing a desired amount of cooling to a quantity of non-liquid conveyable product in a vessel within a given length of residence time in the vessel, comprising:

(A) continuously feeding a mass of non-liquid conveyable product into a vessel, through the interior of the vessel, and out of the vessel, at a rate that provides a given predetermined length of residence time within the interior of the vessel, wherein the non-liquid conveyable product is moved through the interior of the vessel by engagement thereof with an impeller that is positioned in the interior of the vessel; and (B) feeding cryogen out of a plurality of nozzle openings directly into or onto the non-liquid conveyable product in the interior of the vessel while the impeller is moving the non-liquid conveyable product continuously past the nozzle openings, wherein the cryogen is fed into said non-liquid conveyable product from a sufficient number of said nozzle openings to provide the desired amount of cooling to the non-liquid conveyable product within the given period of residence time in the vessel, and wherein the flow of cryogen out of each nozzle opening is continuous or intermittent.

The present invention provides an energy-saving quick-freezing method for golden pomfret. The method is putting golden pomfret into a liquid nitrogen quick-freezer with a cavity temperature of A, and when a core temperature of fish body reaches −6 to −4° C., turning off the liquid nitrogen quick-freezer; when the cavity temperature of the liquid nitrogen quick-freezer rises to B, starting the liquid nitrogen quick-freezer, and when the core temperature of the fish body reaches −19 to −17° C., turning off the liquid nitrogen quick-freezer; and taking out the golden pomfret and storing at −19 to −17° C.; wherein, the A is −105 to −85° C., the B is −95 to −65° C., and A<B.

A delivery apparatus and method for delivering liquid cryogen to a chilling application includes a liquid cryogen feed tank; a liquid cryogen conduit in fluid communication between the feed tank and the application, wherein the feed tank is in fluid communication with a vessel which is in fluid communication with the conduit between the feed tank and the application; a weight measurement device for controlling the weight of liquid cryogen to be delivered to the application through the conduit; a flow controller for controlling the speed of delivery of the liquid cryogen to the application; wherein the application utilizes the liquid cryogen and produces an exhaust gas; a device for measuring the temperature of the exhaust gas, the device in operative communication with the flow controller; wherein the flow controller is configured to vary the speed of delivery of liquid cryogen from the vessel through the conduit in response to the temperature of the exhaust gas.

A high-precision control system and method for shipborne cryogenic flash freezing of an aquatic product using liquid nitrogen is described. The system may include a main control system, a display unit, a liquid nitrogen supply system, a valve control unit, an acquisition unit, and a power unit. A flash freezing process is divided into four stages: a precooling stage, a flash freezing stage, a deep freezing stage, and a thermal insulation stage. Different cooling rates and flash freezing times are used for different stages, where a cooling rate is used in the flash freezing stage is the highest, a cooling rate used in the deep freezing stage is next, a cooling rate used in the precooling stage is the lowest, and an ambient temperature in a device is kept stable in the thermal insulation stage.

An apparatus for introducing dry ice pellets into fresh meat comprises a housing, in which an injection device for introducing dry ice pellets is arranged, and guide channels, which lead to a front face of the housing, for guiding a penetration needle, and a drive device for axially moving the penetration needle. A loading unit can be inserted between a rear portion and a front portion of the housing, which loading unit is provided with feedthroughs, which can be equipped with dry ice pellets and brought into a position in alignment with the guide channels. During operation of the apparatus, penetration channels are first produced, by means of the penetration needles, in a piece of meat to be cooled, into which penetration channels the dry ice pellets are subsequently introduced from the feedthroughs using the penetration needles. The feedthrough enables efficient introduction of dry ice pellets into the meat.

A method may include grinding raw whole muscle meat into a ground meat material and heating the ground meat material to cook the ground meat material into a cooked ground meat material suitable for consumption. The method may also include freezing the cooked ground meat material and mixing the frozen and cooked ground meat material with an additive comprising a starch to produce a meat mixture. The method may further include pressing the meat mixture into a formed shape and slicing the formed shape into meat portions of a predetermined size.
