ABSTRACT:
The apparatus is composed of a vacuum panel insulated cabinet containing six mirrored cylindrical compartments served by transparent sliding doors and their internal space divided by a rotating disc shelf as well as steel rods positioned through the axis shaft of the disc at right angles. The compartments are cooled with water passing through water jackets that surround them, being pre-chilled by having the water coarse through an ice water bath via a coiled and finned tube in a lidded container. Cold air can also be used directly from outdoors to cool the compartments. A remoted powered cooler is held in reserve. In automatic defrost models the apparatus is integrated with the household hot water plumbing.
