Abstract
A microwave-plasma disinfector (Origreen) with a microwave source with multi-feed points and variable output power. It also has a low-temperature atmospheric-pressure plasma source. This versatile microwave-plasma disinfector has the ability to decontaminate heat-sensitive materials by subjecting them to a microwave-assisted plasma with controlled microwave power. This dual-action, at suitable non-destructive microwave and plasma doses, sterilizes the equipment at a lower temperature with higher effectiveness than either plasma or microwaves alone
Claims18
A microwave-plasma disinfector system comprising:
- An exciter comprised of a microwave source and an atmospheric-pressure plasma source;
- and
- a choke that is equal in length to said exciter, is short-circuited, and generates a redirected signal that is shifted by a phase of 180 degrees.
A microwave-plasma disinfector system comprising:
- A cavity adapted to receive an object to be disinfected;
- An exciter comprised of a microwave source and an atmospheric-pressure plasma source;
- and
- A choke that is equal in length to said exciter, is short-circuited, and generates a redirected signal that is shifted by a phase of 180 degrees;
- and
- Wherein said microwave source uses two or more horn antennas to achieve uniform energy distribution over the object located in said cavity;
- and
- an array of infrared sensor located inside said cavity to monitor the energy distribution in said cavity during the disinfection process.
