Storing Solid Material Under Controlled Condition Patents (Class 426/418)
  • Patent number: 4244979
    Abstract: The problem of properly cooking food and handling heated food so that it retains a fresh-cooked taste, fragrance and appealing appearance is solved by apparatus that includes an inner wall means (15) defining an inner chamber (16) and an outer wall means (17) defining an air circulating passage (18) extending in a loop around the inner wall means. Louvered slots (28) with inclined fins (29) are provided in the inner wall means along said air circulating passage that are sufficiently narrow to confine the circulating air substantially to said passage without a significant amount of airflow in direct contact with the food in said chamber and at the same time arranged to permit moisture and heat to diffuse between the circulating passage in the inner chamber via said apertures to control the moisture and heat in the chamber and establish a substantially uniform temperature throughout said chamber.

  • Patent number: 4200657
    Abstract: A method of treating an agricultural product, including the steps of placing the product within a storage container; providing a forced air supply to the container; introducing a gaseous chemical into the container, the particular chemical being selected for minimal sorption of the chemical by the product; and circulating the air and chemical mixture within the container through the product at a low rate of flow, utilizing the forced air supply, for a time sufficient to evenly distribute the chemical throughout the product volume. The rate at which the air is circulated is less than approximately 0.006 cfm/bu and is preferably maintained approximately between 0.0015 cfm/bu and 0.0008 cmf/bu. Hydrogen phosphide (phosphine) gas generated from aluminum phosphide is preferred as the chemical when the process is used for fumigation, but other gaseous fumigants exhibiting a low rate of sorption by agricultural products may also be used.

  • Patent number: 4163070
    Abstract: A freshly slaughtered and skinned meat carcass has its skinned surface covered with a shroud consisting of a rectangular cloth composed of a blend of cotton and polyester fibers and held in place by skewers to cause the shroud to fit tightly against the skinned surface. The shroud is saturated with an aqueous saline solution when applied, and the fully wetted shroud is allowed to lose its moisture in the chilling room as the carcass loses its body heat.

  • Patent number: 4064275
    Abstract: An improved process to hydrate and enrich dry whole grains for enhanced nutritional value for livestock by placing the dry grains in an enclosed storage facility and continuously recirculating water to hydrate the dry grains to the desired amount. The recirculating water may contain feedstuff additives such as vitamins, nutrients and minerals and the recirculating water may further be passed through a pasteurizing unit in order to inhibit the growth of undesirable microorganisms. The recirculating water is fed through a nozzle at the top of a storage facility and allowed to flow rapidly to the bottom of the storage facility and into a sump storage tank. In addition, the process provides for fermenting the nutrient solution prior to or during the time of its recirculation through the column of grain.

  • Patent number: 4062983
    Abstract: A method for holding food and the like at desired temperature and moisture levels for an extended period of time wherein a holding chamber confines a volume of air about a food disposed therein, an air flow supply produces a stream of heated humidified air that is directed in a curtain-like vortex pattern around the outer perimeter of the inside of the holding chamber to form a core of relatively still, heated moisturized air about the food to transmit heat and moisture thereto without a significant amount of air flow in direct contact with the food. A power control circuit is used to selectively operate a blower motor that circulates the air in a closed air flow system, a heating element that heats the air, a removable food rack motor that rotates the food in the holding chamber and lights that illuminate the food in the holding chamber.

  • Patent number: 4054672
    Abstract: Frozen foodstuffs are defrosted under an atmospheric pressure between about 2 atm. and 5 atm. using a liquid or gaseous environment at a defrosting temperature, thereby retaining the cellular structure, texture and appearance of the foodstuffs during defrosting. When the liquid is water, the foodstuffs may be maintained under pressure by immersing them to a depth in excess of 10m, while the medium is preferably a non-oxidizing gas or a gas capable of excluding atmospheric oxygen, preferably carbon dioxide, nitrogen, helium or argon. The defrosting temperature is preferably provided by internal heating of the foodstuffs, e.g. by high frequency dielectric heating, inductive heating or resistive heating.

  • Patent number: 4028774
    Abstract: An enclosure is divided by partitions to define a narrow sinuous passageway for the passage of carcasses from an inlet to an outlet. The sinuous passageway defines adjacent aisle portions and a blower directs refrigerated air downwardly over the carcasses in one of the aisle portions. The air passes under the dividing partition into the adjacent aisle portion and the blower draws it upwardly over the carcasses in that adjacent aisle portion to rapidly freeze a crust on the carcasses during their passage from the inlet to the outlet. The method of the invention is the blowing of cold air over a carcass in one vertical direction then over the same carcass in the opposite vertical direction.

    Abstract: A method of preserving foodstuffs by placing them in a container of given volume in which air at atmospheric pressure is present and selectively removing the oxygen from the air in the container while maintaining substantially atmospheric pressure therein is disclosed. According to the invention, a flow of air is established through the container by means of an external conduit in which the oxygen in the air is catalytically reacted with hydrogen gas concurrently generated and added to the air flow for at least a predetermined length of time after which the generation and addition of hydrogen gas is terminated when the hydrogen/oxygen reaction falls below a given level. Various embodiments of the apparatus for practicing the method according to this invention are described.
