Abstract: A meat press is provided which includes an actuating dolly and a press tree having first and second frames. The actuating dolly includes a subframe that is vertically extendable and carries cylinders that engage portions of the overlying tree when brought into registry therewith. The cylinders engage a linkage which is connected to a second frame and can cause movement thereof in a manner which exerts a compression force on a meat product loaded on the tree. The linkage is constructed and the cylinders are mounted in a manner that allows the cylinders to exert a horizontally directed pulling force on the linkage which then causes vertical movement of the second frame.

Abstract: An apparatus and method is provided for initially freezing a first exterior surface of a product such as a food product. The product is then supported on a perforated conveyor belt with the frozen first exterior surface in contact with the conveyor belt. The product is then further frozen and processed. Because the frozen surface of the product is hard, it does not conform to the surface contours of the belt and the unmarred visual appearance of the product is maintained. In addition, the frozen surface of the product is more easily removed from the belt after complete freezing and damage to the product is less likely to occur during removal of the belt.

Abstract: A freeze wheel is provided with an outer skin on which a food or other type product is placed to be frozen. A chamber is formed adjacent the outer skin and a plurality of nozzles project into the chamber for directing a refrigerant onto the inner surface of the skin. The refrigerant flow is controlled to provide a uniform flow pattern along the inner surface to strip away a boundary layer of fluid and maximize heat transfer across the outer skin. The nozzles are arranged in a series of concentric rings with the nozzles in alternate rows lying in common radial planes. An interior portion of the wheel is closed off by one or more doors which may be opened to allow cleaning of the wheel.
