Abstract
A method and apparatus for using a cryogen cooling articles, particularly having applications for chilling extrusions, food, and similar articles, utilizing dispersion of liquid cryogen into a feed chamber wherein it is substantially vaporized and then circulated through a cooling chamber containing the article to be cooled. A circulation device can circulate the vaporized cryogen through the cooling chamber at a variably controllable velocity to enhance the cooling efficiency using the principle of forced air convection and to provide improved temperature control in the system.
