Abstract:
An impingement plate atomizer apparatus includes an electrostatically charged longitudinal member having an upper surface sized and shaped to receive a liquid cryogen thereon, a lower surface opposite to the upper surface, and at least one hole extending through the longitudinal member; an ultrasonic transducer in contact with the longitudinal member for providing ultrasonic energy thereto for atomizing the liquid cryogen into an electrostatically charged cryogen fog. A method is also provided for providing an electrostatically charged cryogen fog.
Abstract:
A sub cooled liquid delivery system includes at least one feed tank, at least one pressure building apparatus in fluid communication with the at least one feed tank, at least one weight measurement apparatus for measuring the weight of the at least one feed tank and a liquid present in the at least one feed tank, at least one fill conduit in fluid communication with the at least one feed tank for providing the liquid to the at least one feed tank, at least one feed conduit in fluid communication with the at least one feed tank for delivering a subcooled liquid to at least one liquid utilizing process, and at least one pressure building conduit in fluid communication with the at least one feed tank for increasing the pressure within the at least one feed tank. A method is also included to subcool liquid delivery using the system.
Abstract:
The following paragraph is to replace the previous version of the abstract, and includes markings to show all the changes made relative to the previous version:An apparatus and method for chilling or freezing a product includes a freezer having a freezing chamber therein in which a cryogenic substance is provided, and an inlet and an outlet in communication with the freezing chamber; and a plastic film belt constructed and arranged to transport the product from the inlet through the freezing chamber for exposure to the cryogenic substance to the outlet for removal of the product for further processing. The plastic film belt may be formed with one or a plurality of pockets to transport a corresponding amount of product.
Abstract:
A refrigeration system includes a housing having a top, a bottom, first and second opposed sides, and containing an atmosphere; a conveyor apparatus including a self-stacking, self-supported, spiral conveyor belt and a drive mechanism, wherein the conveyor belt includes a plurality of tiers and is at least partially disposed within the housing such that the conveyor belt can travel within the housing from the bottom towards the top of the housing or from the top towards the bottom of the housing; and an atmosphere circulation apparatus having at least one blower in communication with the atmosphere for circulating at least a portion of the atmosphere within the housing from proximate the first opposed side to the second opposed side and back towards the first opposed side, wherein the portion of the atmosphere circulated passes over the conveyor belt in a crossflow manner at least once.
Abstract:
The present invention describes a method and apparatus for controlling the operating pressure of a Reverse Brayton type refrigeration device 70 for the purposes of regulating cooling capacity and coolant inventory control.
Abstract:
An apparatus and method are provided for mixing a gas and a liquid to produce a gaseous vapor of the liquid that is substantially free of droplets. Gas, e.g., carbon dioxide, is divided into first and second streams. The first stream is combined in an atomization zone with the liquid, e.g., acetic acid, to form an atomized mixture of the gas and liquid. This atomized mixture is then contacted with the second gas stream in a mixing zone within a mixing/separation chamber in which the second gas stream vaporizes substantially all of the atomized liquid, and the resulting mixture of gas, vaporized liquid and residual droplets moves to the separation zone of the mixing/separation chamber. In the separation zone, the residual droplets gravitationally separate from the vaporized mixture, and the vaporized mixture free of a substantial amount of residual droplets is removed from the chamber. A vaporized mixture of carbon dioxide and acetic acid is useful as, among other things, a preservative for perishable products, e.g., baked goods.
Abstract:
Food products are frozen or cooled within a housing chamber defined by side walls between an ceiling and floor and having a cryogen supply, a food products conveyor extending into the chamber disposed between the ceiling and floor, by transporting the food products on the conveyor; the chamber containing at least one impingement hood disposed above the conveyor; the impingement hood including a shell including a top, opposed edges and opposed side walls supporting an impinger containing openings. Gas and solid or liquid cryogen are mixed within the impingement hood, the mixture of gas and cryogen are directed to the impinger, and impingement jets of the mixture are directed through an impingement plate onto the food products transported on the conveyor.

Abstract:
A heat exchanger includes a housing disposed in a first atmosphere and having an upstream end, a downstream end and a chamber within the housing; a metallic block disposed in the chamber and having a passageway therethrough and through which a cryogen can flow; and a heat pipe assembly in contact with the metallic block and extending to a second atmosphere which is separate from the first atmosphere for providing heat transfer at the second atmosphere.
Abstract:
A diffuser apparatus for a space of a refrigeration container includes a housing having an internal chamber extending to a nozzle portion comprising a height less than a height of the internal chamber and a width greater than a width of the internal chamber, a fan disposed for operation in the internal chamber, and a heat exchanger disposed for operation in the internal chamber between the fan and the nozzle portion.
