Abstract This paper presents the
results of experimental studies on heat and mass transfer during a microwave
freeze dehydration process. An experimental system and procedure was
developed to freeze dry milk. A 2500-W microwave system with an appropriate
wave guide was set up and instrumented, and a procedure was experimentally
developed to obtain milk powder first by freezing milk and then dehydrating
it at low pressure using microwave energy. An unsteady-state analysis was
used to derive a one-dimensional mathematical model of the freeze dehydration
process in a microwave electromagnetic field. Key Words:
Freeze dry, Microwave energy, Dehyration, Milk. |
