  • Patent number: 4209288
    Abstract: A conventional refrigeration vault has cooling coils and air-moving fans for freezing confections that are conveyed therethrough. An endless conveyor belt describes a tortuous path through the vault and carries the confections in a spaced single-file arrangement. One wall of the refrigeration vault has openings therein, and one reach of the endless conveyor belt extends through the openings to pass by a discharge point, at which finished (hard frozen) confections are removed, as well as a pickup point at which soft frozen confections having a predetermined shape are received. The soft frozen confections are introduced through one of the openings into the refrigeration vault and travel along the tortuous path for a relatively short distance (as compared with the total length of the conveyor within the vault).
