Drying processes
Motivation / Definitions and concepts (wet solid, gaz-liquid-solid equilibrium, wetting enthalpy, sorption isotherms, equilibrium diagrams) / Techniques et set-up (classification, machines often used in the industry, drying by ebullition, drying by flow, lyophilisation, drying of bio-products) / Theoretical principles of drying (drying kinetics, hygrometry, wet air diagram, case study: the drying of cereals in a grain silo) / Alternative mode for providing energy / supercritical drying
Partim B
Fluid/fluid separation and fluid/solid separation involving mass transfer

Teaching methods
Lecture with a powerpoint presentation as the main support (available via Moodle). Even if the slides are used as a support for the lectures, an important part of the course is given orally and on the blackboard (e.g. explanations, examples, mathematic developments, etc.).
Quantitative exercises of dimensioning with a tutor.
Scientific articles are recommended for reading as a complement to the course.
Students may be instructed to visit a production plant of their choice and to study a unitary operation involved in the production process. If so, a short, didactical and critical report is requested, in the form of a poster. The report is presented to other students.
Some lecture may be tought remotely (Teams).

Evaluation methods
Written exam systematically covering the LO (theory and exercises).
If a field study in the industry is organized, the evaluation of the report and its presentation accounts for 20% of the final grade.
