Book: Mujumdar Arun S. Handbook of industrial drying Vol. 1

Details on the course materials (applies in this implementation): 

For students, who understand Finnish, a course handout

Holmberg Henrik, Ramm-Schmidt Leif, Kuivaus- ja haihdutusprosessit teollisuudessa. You can download the Finnish course material on MyCourse as a pdf-file

For students, who do not understand Finnish, the following handbook 

Mujumdar Arun S. (editor), Handbook of Industrial Drying (e.g. second version). The following chapters

Chapter 1: Drying of solids: Principles, classification, and selection of dryers

Chapter 3: Basic process calculations

Chapter 4: Transport properties in the drying of solids (Moisture diffusivity, Equilibrium moisture content)

Chapter 35: Superheated steam drying

The book contains a lot of imformation on various dryers. This is additional material.

For all students

A compendium about thermodynamics of humid air. You can download the material as pdf-file on MyCourses.   

All lecture slides will be uploaded on MyCourses.

Substitutes for Courses (valid 01.08.2018-31.07.2020): 

Ene-59.4130. Kuivatus- ja haihdutusprosessit teollisuudessa

Prerequisites (valid 01.08.2018-31.07.2020): 

Energy and mass balances of stationary flow systems and thermodynamics of humid air

Grading Scale (valid 01.08.2018-31.07.2020): 


Details on the schedule (applies in this implementation): 

The course has 10 lectures and 5 calculation exercises. Every calculation exercise has a "Star Problem". If you solve the star problem and submit it for grading you can get some extra points. You can maximally get 2.5 extra points. These points are taken into account in exam points since you have passed the exam. In other words, you must first get the minimum number points (7.5/20 points) before the extra points are considered. 

Preliminary course content and schedule will be uploaded on MyCourses in the beginnig of the course
