Responsible consumption and production

Academic Year 2018/2019

Learning outcomes

On successful completion of the module, students will know the fundamentals of the specific unit operations which are the basis of the food industry. Furthermore they will be able to operate effectively on the parameters of the process and on the characteristics of the apparatuses which finally determine the economic and the quality of the product.

Course contents

Requirements/Prior knowledge

A prior knowledge and understanding of mass and energy balances, mechanisms of heat transport and basic chemical kinetics is required to attend with profit this course.

In addition, students should master the utilization of spreadsheets.

Fluent spoken and written Italian is a necessary pre-requisite: all lectures and tutorials, and all study material will be in Italian.
