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

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

This invention relates to a novel two-stage dry ice system for preserving perishable items during transport and methods thereof. The improved two-stage dry ice system includes dry ice and a phase change material specifically configured within a single and continuous holding volume with perishable items. Preservation of the perishable items for extended durations in comparison to other refrigeration techniques can be achieved as a result of the two-stage dry system having the ability to re-orient itself during transport.

Modified dry ice systems and methods for preserving perishable items within a single holding volume
