Learning unit contents
This course aims to develop, through exercices, laboratory experiments and group projets, complementary knowledges on cooling and drying processes, as well as some skils on the managements and designing of biological materials preservation processes (*).
In the classroom
Reminder of theoretical notions of conservation processes
Problem solving based on the use of humid air (H,x) diagrams
Problem solving focused on dehydration kinetics and sorption phenomena
Presentation of the problem related to the choice and use of refrigerants
Problem solving based on the use of thermodynamic diagrams of refrigerant
Design and dimensionning of cooling and drying systems
In the laboratory (mandatory participation)
Study of the components and the operation of a heat pump
Study of the components and operation of a freeze dryer
Study of the components and operation of a spray dryer
Study of the dehydration kinetics of solid materials on a fluidized bed drer
Working group (Project thematic imposed)
Project 1 : Design and dimensionning of a cooling system
Project 2 : Design and dimensionning of a liquid drying system
Project 3 : Design and dimensionning of a moving-bed dryer
Project 4 : Design and dimensionning of a pneumatic dryer
Synthesis report and concept presentation

Learning outcomes of the learning unit
At the end of this course the student must :
1) be familiar with the main components of cooling and drying systems
2) know how to use thermodynamic diagrams of air and refrigerants
3) be abble to give an opinion on the cooling, drying and other systems used for the preservation of biological materials
4) quantify different aspect related to the kinetic of drying, sorption and cooling, based on data collected during experimentation carried out by himself
5) be abble to write the terms of references for a specification for the disign of cooling or drying systems
