[Problem] To transport food products or the like at a low temperature and treat same. [Solution] In the present invention, by switching between different power supplies for a low-current high-voltage generation device, low-temperature storage can be performed using the same electric-field treatment device start-to-finish. Using a conventional electric-field treatment device, redundant capital investment can be eliminated and low-temperature non-frozen physical distribution can be implemented start-to-finish in the same temperature environment and using the same electric-field treatment device from transport of high-mix low-volume foodstuffs from the area of production or a processing center to terminal storage (provision for consumption or foodstuff delivery) and used with a reusable-container system. The present invention uses a reusable-container system whereby redundant capital investment for electric-field treatment, transport, and storage can be eliminated and low-temperature non-frozen physical distribution can be implemented start-to-finish at the same temperature and using the same electric-field treatment device from the transport of high-mix low-volume foodstuffs from the area of production or a processing center to terminal storage. Foods or the like are protected from shifting, collapse, and vibration from above, below, in front, behind, the left, or the right.La présente invention concerne le transport de produits alimentaires ou analogues à basse température, ainsi que leur traitement. La solution selon linvention consiste à permettre un stockage à basse température, par la commutation entre différentes alimentations électriques pour un dispositif de génération haute tension et faible courant, en utilisant le même dispositif de traitement de champ électrique du début à la fin. Au moyen dun dispositif classique de traitement de champ électrique, il est possible déliminer les investissements en capital redondants et de mettre en œuvre une distribution ph
