Abstract: A method of making precooked meat pieces using a hybrid cooking system comprises preheating meat pieces to a temperature of at least approximately 140° F. to create preheated meat pieces. The preheated meat pieces are transferred to an oven heated with an external heating source. The oven includes internal surfaces, and the external heating source assists in keeping the internal surfaces at a temperature below a smoke point of fat from the meat pieces. The preheated meat pieces are cooked in the oven to a water activity level of 0.92 or less to create precooked meat pieces. Optionally, flavoring could be applied to the precooked meat pieces after the precooked meat pieces have been removed from the oven and before the precooked meat pieces have cooled.

Abstract: In a method of making a molded article for use in a casting process, sand particles are mixed with protein and water to effect a coating of protein on the sand particles. Then, the protein coated sand particles are dried and blown into a pattern mold to form a molded article without active cooling of the coated sand particles. Steam is then passed through the molded article to hydrate and melt the protein, thereby forming bonds between contiguous sand particles. Finally, hot, dry air is passed through the molded article to harden the protein bonds between the contiguous sand particles. This forms a protein coated sand core for use in casting molten metals.
