Claim:
A freezing system for continuous production of frozen comestibles, comprising: a plurality of trays for carrying comestibles to be frozen; an insulated enclosure having a first end and a second end; passive tray guides positioned within the enclosure receiving the trays and defining two or more levels for travel of trays through the enclosure between the first and second ends in an abutted relationship, a refrigeration system providing cold air to the enclosure to thereby freeze the comestibles; a tray advancement mechanism inserting successive trays into the enclosure and for advancing the trays longitudinally along the passive tray guides in the two or more levels, the trays advanced along the guides in an abutted relationship; first and second multiple-level elevators at opposite ends of the insulated enclosure for advancing trays from one level to another level within the enclosure, each of the first and second elevators configured to receive trays at more than one level simultaneously; wherein the first and second multiple-level elevators and the tray advancement mechanism operate in a manner such that trays are successively advanced into the enclosure to fill all levels until the tray guides are substantially filled with trays, and wherein thereafter for every tray entering the enclosure a tray exits the enclosure carrying frozen comestibles, thereby providing a continuous production of frozen comestibles.
