  • Patent number: 10440979
    Abstract: A method of using a fluid-immersion storage and cooking device having a thermal container that defines a first volume and a second volume includes disposing a first food item in the first volume. A second food item and a third food item are disposed in the second volume in a first position and a second position, respectively. A volume of fluid having a first temperature is circulated through the first volume to transfer thermal energy to the first food item. After a predetermined time, at least a portion of the volume of fluid is heated to a second temperature. A portion of the volume of fluid is conveyed to the second volume such that (1) the second food item is substantially submerged in the portion of the volume of fluid and (2) the third food item is disposed substantially outside of the portion of the volume of fluid.

  • Patent number: 8348079
    Abstract: The invention concerns a closure for a cylindrical can (10) The closure includes a flexible member (11) of the easy-open type secured across the open end of the can (10). A rigid, screw cap (22) is screwed over the thus sealed end of the can. An annular, resilient member (24) depending downwardly from the underside of the end wall of the cap (22), engages the membrane (11) in the vicinity of the end flange (18) of the can body (10) thereby strengthening the seal between the membrane (11) and the flange (18). This advantageously permits cooking of the contents of the can with the flexible membrane (11) in situ, thereby giving rise to a can having an easy-open end, the contents of which can are cooked and sterilized using conventional processing lines.

  • Publication number: 20090223506
    Abstract: The technical simplification of the invention is on FIG. 5. That is X<Y<Z. This simple expression represents the elevation of the three nozzles on the bottom door. The elevation difference of these three nozzles is what sets my crateless retort apart from the traditional crateless retort. Drain nozzle is at the lowest elevation. Water inlet nozzle is at the middle elevation. Finally, the steam nozzle is at the highest of the three elevations. This simple equation, X?y?Z, demonstrates the fact that any water entering the retort will rise in level and ultimately mix with the steam to automatically create an unstable condition. The lower temperature water would never reach the cans in the bottom of the retort without this unstable condition occurring. This unstable condition will prevent under processing because the cook would be terminated, and product quarantined inside the retort.

  • Patent number: 5902618
    Abstract: An apparatus for chilling hot-bagged food includes a refrigeration device providing chilled air and an enclosure for containing the chilled air. A fan blows the chilled air in a stream within the enclosure and an open-work support movably holds a bag of hot food within the enclosure and in the path of the stream of chilled air. Thus, movement of the bag of hot food both agitates food within the bag and exposes surfaces of the bag to the stream of chilled air to rapidly cool the hot-bagged food. A method of processing food includes packaging and sealing a quantity of cooked hot food into a plastic bag then placing the plastic bag and hot food in an open-work basket movably mounted on a support.

  • Patent number: 5896872
    Abstract: Unopened packages, containing an edible food product pre-treated with a heat shock preservation process, can be sanitized in a hospital dishwasher by a method that includes washing the package outer surface with detergent, rinsing the package surface with a solution containing a sanitizing agent, and drying the package outer surface. The method is applicable to various food products, e.g. individual milk or juice packages, distributed to patients in hospitals. Use of the method permits unopened food packages handled by the patient to be supplied to other patients without worrying that germs and contaminants might be transmitted from one hospital patient to another hospital patient.

  • Patent number: 5895626
    Abstract: The invention presents a method, apparatus and container for sterilizing solid matter or liquid matter containing solid matter efficiently in a short time, while preventing deterioration of quality or decline of flavor.In this method, solid matter (a) and liquid matter (b) are separately heated and sterilized, and both are mixed after being sterilized, and put and sealed in a bag (c) or container. When heating and sterilizing the solid matter independently, the solid matter is weight and dispensed in each retainer (c) by the portion of one pack each, and sterilized, and is transferred, after being sterilized, from the retainer (d) into a bag (c) or container, and sealed. Sterilization is executed by rotating the retainer (d) and inducing an agitating action on the inside solid matter.

  • Patent number: 5846594
    Abstract: Fish of the Salmonoid family (salmon, trout and their relatives) is preferably first trimmed to remove heads, tails, fins, entrails, skin and bones and cut into fillets or loins to facilitate further removal of dark meat, bone, bruised meat, blood and viscera. The remaining light meat is then vacuum tumbled with a marinade solution under reduced ambient pressures at rotational speeds and for times dependent upon the thickness of the fish fillets or loins. During the vacuum tumbling step, penetration of the marinade solution into the light meat is facilitated and thereby the mobility and accumulation of curd-forming, soluble fish proteins are greatly diminished, serving to fix such protein in place, to ultimately provide a greatly visually-reduced curd product. Additionally, this vacuum tumbling step softens any pin bones which may remain to ultimately provide a virtually boneless product.

  • Patent number: 5772958
    Abstract: The method and the apparatus according to the invention relate to pasteurization of products in a tunnel pasteurizer. In the application of heating systems comprising water/steam heat exchangers in the zones for heating of sprinkling water, the pipelines and the valves for controlling the water and the steam become very complex and vulnerable, and the number of analog valves for steam become equal to the number of heat exchangers as a minimum. Leakages in analog valves for steam are frequent after some time in operation. According to the invention this problem is eliminated in that hot water is taken out under low pressure from a heating source (7) comprising a heat-insulted storage tank and a shared source of heat, where the water is circulating constantly, said hot water being supplied in a controlled amount directly to each zone (14b, . . .

  • Patent number: 5620725
    Abstract: When dispensing carbonated beverages, particularly beers and especially draught stout, it is desirable to obtain a close-knit creamy head. To achieve this a container (1) includes a separate closed hollow insert (5) containing substantially no oxidising gas and means (6) responsive to opening of the container (1) to provide communication between the inside of the insert (5) and beverage (7) contained in the body of the container (1) upon opening it to jet gas from the insert (5) into the beverage (7). The means (6) preferably has the form of a pressure responsive valve. The insert (5) may be arranged so that its internal pressure is increased after the container (1) is sealed or the means (6) may have a different relief pressure when initially inserted into the container (1) from that upon opening the container (1).

  • Patent number: 5443853
    Abstract: Disclosed are vacuum-packed food packages (10) having enlarged head spaces (56) under high vacuum, which enable food products (58) to be retorted after sealing, with resulting improved flavor, color, texture, and/or nutrient retention. Easily removable press-on, pry-off closures (13) having movable insert disks (16) in an outer shell (14) are also disclosed. Pressing the shell upward to remove it from a container (11) first pries a protrusion (28) inside the shell over a snap rib (22) around the container, then moves the shell upward relative to the disk until the snap rib engages the edge of the disk and lifts the disk to break the seal. A tamper evidencing band (22), if included, is broken before the shell is pried off or the disk is lifted. Food packages which automatically open when heated in microwave ovens are also disclosed.
