LOW-TEMPERATURE CONSERVATION DEVICE WITH THE DISINFECTION AND FRESHNESS PRESERVATION FUNCTIONS Russian patent published in 2018 - IPC F25D23/12 

FIELD: electrical equipment.

SUBSTANCE: low-temperature preservation device with the disinfection and freshness preservation functions represents chambers, low-temperature electronic emission unit, cooling system, electrical system and housing. Electron emission unit emits electrons and forms the certain density nanoparticles with the negative electric charge, providing the conservation chambers disinfection. Nanoparticles with a negative electrical charge sticking to the stored products surface and water molecules, form hydration films on canned products while maintaining the water content therein.

EFFECT: use of this invention ensures the canned articles freshness and increases the canned products shelf life.
