Abstract:
An apparatus and method for providing treatment to a continuous supply of food product using a vacuum process includes compartments for receiving, treating and expelling food products that are delivered to the apparatus on a continuous basis. The compartments have different pressures therein and in a preferred embodiment are separated from each other within the apparatus to treat the food product on a continual basis, as opposed to a batch-by-batch basis.
Abstract:
An apparatus and method of cooling products includes a conveyor for transporting the products, through a refrigeration medium for cooling the products, agitation means disposed proximate to the conveyor for selective, intermittent contact with the conveyor to displace the conveyor from a plane of travel, thereby displacing the products on the conveyor during freezing to prevent the products from adhering to the conveyor or other of the products during freezing, at least one of the agitation means and the conveyor constructed and arranged to be positioned away from each other for the conveyor to move uninterrupted along the plane of travel.
Abstract:
An apparatus and method is provided for freezing, storing, and/or shipping products, in particular fish, at super-frozen temperatures. The apparatus includes a modular cryogenic cooler for removably interfacing with an insulated shipping container to maintain the interior of the container at a super-frozen temperature less than or equal to about −50 degrees C. Aspects of the method include a delivery method for providing an essentially unbroken delivery chain of frozen products from a location of freezing (to a super-frozen temperature) to a location of defrosting the products (e.g., a point of sale and/or consumption of the products).
Abstract:
A method for reducing a temperature of a product in a freezer includes providing a product to a chamber of the freezer; dividing a portion of the chamber disposed between a pair of baffle assemblies in the freezer into an intake zone and an outflow zone; moving each baffle assembly of the pair of baffle assemblies in the chamber 90° degrees out of phase with each other for directing a gas flow in the chamber; oscillating the gas flow within the chamber between the intake zone and the outflow zone during the moving the pair of baffle assemblies; injecting a cryogen substance into the chamber for cooling the gas flow; and contacting the product with the cooling gas flow.
Abstract:
A heat exchanger apparatus includes a housing having a sidewall defining a chamber in the housing for containing a cryogen; and a first insulation member movably mounted for coaction with the sidewall, the first insulation member moveable to a position to expose or cover a select portion of the sidewall to provide a heat transfer effect.
Abstract:
A freezer includes a housing having a sidewall defining a chamber, and an inlet and an outlet in communication with the chamber; a pair of baffle assemblies spaced apart and disposed in the chamber, a first one of the pair movable 90° degrees out of phase from a second one of the pair; a plate disposed in the chamber and extending between the first and second baffle assemblies for dividing a portion of the chamber into an intake zone and an outflow zone; a fan disposed in the chamber between the first and second baffle assemblies and in communication with the intake and outflow zones for providing a gas flow from the intake zone to the outflow zone; and a delivery apparatus in communication with the chamber for delivering a chilling substance to the chamber for reducing a temperature of a product. A method is also provided.
Abstract:
A freezer includes a housing having a space therein for receiving a cryogenic gas, and an inlet and an outlet in communication with the space; a conveyor belt having an outer edge and being arranged for movement through the space for transferring a product from the inlet through to the outlet; a solid longitudinal member disposed in the space adjacent the outer edge for segregating the space into an upper chamber and a lower chamber; and a transfer duct operatively associated with the housing and having a first opening in communication with the upper chamber for receiving the cryogenic gas from the upper chamber and a second opening in communication with the lower chamber for expelling the cryogenic gas into the lower chamber.

Abstract:
An impingement plate atomizer apparatus includes a 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; and an ultrasonic transducer in contact with the longitudinal member for providing ultrasonic energy thereto for atomizing the liquid cryogen at the upper surface into a cryogen fog.
Abstract:
A pressure control apparatus for a cryogenic storage tank includes a heat pipe extending into the storage tank and having a first end in contact with liquid cryogen in the storage tank, and a second end exposed to an atmosphere external to the storage tank such that heat flux occurs in the liquid cryogen proximate the first end of the heat pipe for providing a cryogenic gas and pressure to the liquid cryogen in the storage tank. Another embodiment includes a sleeve for the second end to control the heat flux in the liquid cryogen.
