Meat is chilled immediately after slaughter. Most of the subsequent opera- tions in the cold chain are designed to maintain the temperature of the meat Cooking is a very common operation in the production of many meat products and operators appreciate the importance of rapidly cooling the cooked product. However, any handling such as cutting, mixing or tumbling will add heat to the meat and increase its temperature. A secondary cooling

In specifying refrigeration equipment the function of the equipment must be absolutely clear. Refrigeration equipment is always used to control tem- perature. Either the meat passing through the process is to be maintained it its initial temperature, for example as in a refrigerated store or a packing operation, or the temperature of the meat is to be reduced, for example in a blast freezer. These two functions
