2. Improving the understanding of heat transfer when boiling solid foods
University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)Abstract : Determination of the fluid-to-particle heat transfer coefficient hfp is a fundamental problem in food engineering. Solutions to this problem help food technologists and cooks prepare foods with desired characteristics more efficiently in time and energy use. This study aims to determine the hfp-value in simmering and boiling solid foods. READ MORE
