MAGNETRON BLOWER

Blowers are used in restaurant equipment to diffuse heat, aid in convection, and circulate cold air. A blower is a centrifugal fan. It is a mechanical device for moving air or other gases. Blowers often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a "blower fan", or "squirrel-cage fan" (because it looks like a hamster wheel). These fans increase the speed and volume of an air stream through rotating impellers.

A magnetron is a high-powered vacuum tube that generates microwaves using the interaction of a stream of electrons with a magnetic field while moving past a series of open metal cavities (cavity resonators). Electrons pass by the openings to these cavities and cause microwaves to oscillate within. The frequency of the microwaves produced (the resonant frequency) is determined by the cavities' physical dimensions.

The magnetron serves as an oscillator, generating a microwave signal from direct current electricity supplied to the vacuum tube. The microwave radiation that the cavities produce is collected up and channeled by a kind of funnel called a waveguide into the cooking compartment of a microwave or rapid cook oven.
