Patent application: Modified dry ice system

Ben Welter - Tuesday, March 24, 2020

U.S. patent application 20200072523 (inventors Chang Yup Seo, Woodridge, Ill.; Soujanya N. Jampala, Chicago, Ill.; Sameer H. Israni, Darien, Ill.; and Robert R. Sever, Arlington Heights, Ill.):

"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."
