Abstract: An improved storage assembly for use in apparatus for preserving and rejuvenating items such as vegetables and the like in a refrigerator maintained at a temperature of between 33.degree. F. and 58.degree. F. by surrounding the items with a fog composed of water particles having a diameter of between 1 and 20 microns generated by means of an ultrasonic wave nebulizer with a transducer element. The storage assembly includes a cover and a pan in sealing arrangement with the cover and movable relative thereto. A water reservoir is located in close proximity to the pan and has the transducer element of the ultrasonic wave nebulizer in communication with water in the reservoir for generating the water particle fog. A passageway is provided for delivering the fog from the interior of the reservoir to the interior of the pan.
