Microwave Heating Systems Conveyor Microwave Dryer

Microwave heating is a process within a family of electroheat techniques such as induction radio frequency direct resistance or infra-red heating all of which utilise specific parts of the electromagnetic spectrum These processes supplement and in specific cases totally replace conventional heating or drying systems used in industry This is because some conventional systems are very

Microwave Assisted Extraction

To reduce degradation at high operating temperature vacuum microwave-assisted extraction (VMAE) has been developed to operate at low oxygen subpressure in vacuo (Wang et al 2008) When conventional solvent extraction was replaced by VMAE to extract IAA from plant tissues improved extraction efficiency and decreased extraction time was obtained ( Hu et al 2011 )
