Disclosed are methods and apparatus for forming frozen food products, especially frozen foamed food products wherein the products contain bubbles having a reduced average size preferably in a narrow size range or contain ice crystals having reduced size.

Method and apparatus for producing frozen food products

Animals such as poultry are stunned while still caged and on a vehicle or stationary platform prior to processing the animal by isolating the atmosphere surrounding the animal, adjusting the composition of the isolated atmosphere by introducing a gaseous mixture that brings the animal to the desired state, and evacuating or exhausting the gaseous mixture.

System and method for treating live cargo such as poultry with gas

System and method for controlled atmosphere stunning of chickens or turkeys in a batch mode is provided. The disclosed method includes the steps of: loading one or more batches of chickens or turkeys in a stunning chamber and sealably enclosing the stunning chamber to isolate the atmosphere therein. Carbon dioxide is then introduced to the isolated atmosphere in a series of three, four, five or more phases to humanely stun and eventually kill the poultry. The carbon dioxide containing atmosphere is subsequently forcibly exhausted from the stunning chamber and the ranks of cages or modules containing the stunned poultry are advanced to a subsequent processing station such as a tipper or dumping station.

Animals such as poultry are stunned while still caged and on the vehicle that carries them to a processing plant, by exposing the animal to an atmosphere of gradually lessening oxygen content.

Apparatus and methods for cooling or heating product by passing it through a tunnel in which gaseous heat transfer medium such as cryogen vapor or steam is impinged toward the product and then drawn away from the product in a manner that minimizes intersection with impinging medium.

Cooling or heating with multi-pass fluid flow

A unit for cooling or heating objects on a helical belt includes between adjacent tiers of the belt a distributor having a plurality of slots through which air or other gaseous heat transfer medium can be impelled onto product passing on the belt below the slots.

Helical impingement cooling and heating

An impingement cooler or freezer includes at least one impingement section, having a plurality of channeling means defining apertures enabling cooling fluid impingement flow toward and onto objects on a conveyor and defining a channel through which the cooling fluid from the objects flows into a duct which carries the fluid to a unit that chills the fluid, and includes passage means which receives cooling fluid from said apertures and lets it enter the duct after having flowed toward and onto said objects, the fluid being impinged and recirculated by a fan.

Impingement cooler with improved coolant recycle

A device useful for delivering carbon dioxide snow comprises a supply conduit for providing a flow of pressurized carbon dioxide, a plurality of tubes disposed side by side, each tube having a constant cross-sectional configuration and area throughout its length, each tube having a first end the peripheral edges of which are sealed to the outside of the conduit wall and a second end which is open to the ambient atmosphere, and a plurality of apertures for carbon dioxide to flow through the conduit wall and expand to solids and vapor, there being at least one aperture communicating with the interior of each of said plurality of tubes.

Device and process for generating carbon dioxide snow

Method and apparatus for chilling a food product

A cryogenic vessel system for containing cryogenic fluid wherein heat leak into the vessel interior is counteracted by refrigeration generated from energy provided by a pulse generator.

Cryogenic vessel system with pulse tube refrigeration

A cooling tunnel system that includes a conveyor for carrying objects through a tunnel chamber. The conveyor enables a cooling fluid to pass therethrouqh and about the objects. A plurality of slot means feeds the cooling fluid to the conveyor means. Each slot means includes at least one aperture for enabling vapor flow onto and about the objects. A plenum adjacent the plurality of slot means distributes the cooling fluid. And at least one fan in the tunnel chamber causes a flow of the cooling fluid into the plenum and through the slot means with sufficient velocity to impinge upon and cool the objects and to recirculate the cooling fluid within the tunnel chamber.

Impingement cooler

A thermal insulation panel exhibits little or no warping due to temperature differences between different portions of the panel. The panel comprises insulation material and an envelope for encapsulating the insulation material. The envelope comprises a base member and a cover member. The cover member is supported by the base member in a floating and sealing engagement with the base member. The cover member can slide relative to the base member to compensate for differential thermal expansion effects on the respective base member and cover member. In an alternative embodiment the cover member is adapted to be exposed to a temperature significantly below the temperature to which the base member is exposed. The cover member is formed of a metal having a low coefficient of thermal expansion to compensate for differential thermal expansion effects in the respective base member and cover member. The cover member and the base member are joined to provide the envelope with a hermetic seal.
