ABSTRACT:
A method of reassuring internal temperaures of canned foods under actual operating conditions by placing recyclable thermal simulators in each batch of canned foods during the actual processing. A recyclable thermal simulator device having the same thermal characteristics as the particular canned food being simulated. A method for manufacturing recyclable thermal simulators by equipping a container substantially identical to those simulated with a suitable temperature indicator, filling the container with a porous, open-celled, sponge-like matrix material, uniformly distributing a liquid of a pre-determined specific gravity throughout the matrix material by means of a partial vacuum usually identical to that drawn on the canned food simulated and sealing the container. Matching the thermal characteristics of different canned foods is generally accomplished primarily by varying the matrix density, the specific gravity of the liquid, and the percentage of open cells in the matrix material and by employing identical containers and drawing the same partial vacuums used by the canned foods simulated.
