HEAT AND MASS TRANSFER IN FOOD PROCESSING
Learning outcomes of the course unit
Knowledge and understanding:
At the end of the course the student will learn the basic principles of heat and mass transfer and fluid flow referred to food processing.
Applying knowledge and understanding:
The student will acquire knowledge about the application of transport phenomena principles to processes involved in engineering applications, with particular reference to the food industry.
By the end of the course the student will have the tools to critically evaluate the design choices in the field of heat transfer apparatuses design.
The student must possess the ability to present clearly the procedure adopted in the design of heat transfer apparatuses.
To follow the course with profit requires knowledge of the basic concepts of Applied Physics.
Course contents summary
The course is structured into two parts: theory and practical lessons. The theory lectures cover the following subjects: Steady and un steady heat conduction. Convection. Mass Transport. Analogy between the transport of energy, mass and momentum. Heat transfer in boiling and condensation. Convective heat transfer enhancement. Heat exchangers. Rheology. Computational fluid flow and heat transfer. Inverse problem solution.
The practical lessons are integral part of the course and they are dedicated to numerical exercises that provide the opportunity to apply the skills and knowledge acquired in the course.
Part of the practical activity is carried out in the computer lab and it is focused on the application of numerical analysis tools to heat transfer and fluid flow problems. In order to acquire an applicative knowledge this part of the course is based on practical lectures to be held with the use of the Matlab and Comsol Multyiphysics environment.

The theoretical part of the course will be illustrated by means of lectures.
Part of the practical activity is carried out in the computer lab and it also includes an activity pursued independently by the students, followed by an elaboration and discussion of the results.
Assessment methods and criteria
The exam is based on a written/practical test, followed by an oral examination. The verification is so weighted: 50% written test (correct resolution of a practical exercise), 50% oral exam (correct and complete answer to theory questions and speaking ability).
In the written test, reference texts, thermodynamic tables and lessons notes can be consulted.
The results of the written test is communicated forthwith; The final vote shall be communicated immediately at the end of the oral exam before the registratrion.
The Laude is added in case of excellent score in each item (written test and oral exam) and in case of particular communicative and speaking ability with reference to the specific field.
