FOOD-3170: Food Processing II Assignment 2 Due Friday, February 9 , 202 4 by 3:00 pm (12 marks total) The following sheets provide information for you to use in calculating the time taken for various products to freeze using Plank’s equation. There are ten sets of data from which to choose. If your ID number ends in “0” (i.e., “zero”), then select the data with that designation. If your ID number ends in a “1”, then select the indicated data set, and so on. You are to calculate the predicted freezing time for an infinite slab, and infinite cylinder, and a sphere using the data provided. Just for clarification, carrots, parsnips, horse radishes, cucumbers, and bananas should all be treated as cylinders. The given diameter can be treated as an average uniform diameter. The densities, thermal conductivities, and heat transfer coefficients are for calculation purposes. They are not actual values. The freezing points, and latent heats are actual literature values for each material. Please include you r calculations for the three parts of Plank’s Equation as was done in the tutorial. This will make it easier for the Teaching Assistant to mark your answers. You will find Plank’s Equation and the required shape factors in the tutorial notes. Be sure to include the units in your calculations and express the freezing times in minutes (to one decimal place.) Four marks will be allocated for each calculation.
