Summary on Grant Application Form
The food industry needs an array of techniques to get heat into and out of food materials quickly in order to ensure food safety. In addition textural and structural properties of the food material need to be manipulated during the processing. This project will look at these problems with particular focus on the use of scraped-surface heat exchangers (SSHE). The aim of the project is to develop mathematical models of the various phenomena occuring within a SSHE. These models will look at the flow of the material with particular attention on the significant shear-thinning and heat-thinning behaviour of most food materials. The very large nonlinear interaction between the heat transport and the fluid flow resulting from these properties will be investigated theoretically. Careful attention will be paid to the investigation of the behaviour near the moving scrapers as well as the other larger scale phenomena. The mathematical models will be studied with both analytical and numerical methods. Analytical progress will be made by exploiting various asymptotic limits relevant to the numerous materials that are used in these systems and the typical geometry of SSHEs. The project involves collaboration between theoreticians and experimental researchers and will be done in close collaboration with Chemtech International Ltd and Tetra Pak Inc both of whom produce food processing equipment and who will provide a direct exploitation route for the research ideas.
