Disclosed is a technique for characterizing a product utilizing novel measurements based on the reactive and resistive signals exhibited by the product in an electromagnetic field.

Temperature control using applied electromagnetic fields

Particulate material is cooled by passing into the material a coolant stream of liquid nitrogen having a gaseous product around at least a portion of the liquid nitrogen, wherein the coolant stream is formed outside the particulate material in a nozzle body from which the coolant stream is passed into the particulate material.

Cooling particulate material with nitrogen

When a food processing vessel under vacuum is repressurized, the tendency of product in the vessel to be forced into feed lines is relieved or overcome by establishing an effectively high pressure in the feed lines.

Vacuum breaking without feed line clogging

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.
