Electric field tech in new refrigerated ocean service launched

Tokyo-based Sumitomo Corporation and Orient Overseas Container Line Limited (OOCL), with headquarters in Hong Kong, on February 28th, announced the signing of a business alliance agreement to provide refrigerated ocean transport that utilises electric field technology and realizes the long-term preservation of freshness for a variety of commercial products.

International transportation of perishable products, which must preserve freshness, faces challenges to be transported in the shortest possible transit time in ocean transportation, and high-cost burden in air transportation.

To expand food supply areas and ensure a stable supply of products, there was a necessity to develop a service that enables long-term ocean transportation utilising refrigerated storage technology with minimal quality loss.

Taking advantage of the development of electric field containers conducted by Japanese MARS Company, Inc., Sumitomo Corporation established an electric field container procurement system with the cooperation of Fukuoka-based Daiichi Institution Industry Co., Ltd., which manufactures and sells electric field-related equipment, and OOCL.

Additionally, Sumitomo Corporation also obtained patents, including one for a “food transportation method” that lowers the non-freezing temperature of food products and improves the freshness retention effect by shrink-packing the food products with a high degree of vacuum in an electric field environment.
