Abstract
The degree of roasting of materials roasted by application of microwaves is regulated by a system free from any energy source which receives material from a microwave roaster and retains it for a time for completing roasting and varying and regulating the final degree of roasting of the material by regulating the feed of the roasted material from the system to a quenching zone. The microwave roaster includes a horizontal rotatable tube which has baffles for transporting the material to be roasted through the tube such that it reaches a roasting temperature at the outlet of the tube for receipt by the system for achieving the desired degree of final roasting.
