description An apparatus 20 for microwave vacuum-drying organic materials such as foods and bioactives has a plurality of microwave generators 50 actuated so as to cause interference between their respective microwave streams and evenly distribute the microwave energy across the vacuum chamber 34. The microwave-transparent window 36 in the chamber is arranged so the organic material to be dried is moved across it on a conveyor belt 60 and the microwave energy passing into the chamber 34 immediately encounters the organic materials, thus attenuating the energy and reducing arcing.
