Abstract
Abstract A system for cooling and freezing goods by cooled air is described, in which a series of large, rectangular plates carrying the goods pass over a first roller track into an ascending lift in a freezing room. The lift successively receives the plates and carries them stepwise to the top of the freezing room where the plates are carried over in a descending lift, which is operated in time with the ascending lift, and which successively deposits the plates on a second roller track for removal from the freezing room.

A system for cooling and freezing packed and unpacked goods with cooled air comprising: (a) a freezing room; (b) a goods loading room adjacent the freezing room; (c) a series of substantially rectangular, large plates supporting the goods during passage through the freezing room; (d) a first roller track serving to support a plate while being loaded in the loading room adjacent the freezing room; (e) an ascending lift and a descending lift within said freezing room being adapted to move stepwise in synchronization, the said first roller track leading to the ascending lift; (f) means for moving a loaded plate along the first track of rollers into the ascending lift, and means for activating the lifts to perform one step of movement; (g) a roller track adapted to receive the top loaded plate from the ascending lift, carrying it over and depositing it in the descending lift; (h) a roller track placed under said first roller track to receive the bottom plate with frozen goods from the descending lift and carry it back to the loading room for unloading; and (i) the said roller track defined in clause (h) terminated by a movable part adapted to be raised and form part of the said first roller track, thus serving to return an unloaded plate for reloading.
