E Beam Sterilization Equipment

Contents

A 10MeV E Beam Sterilization Equipment is a device that uses a microwave field to accelerate electrons to 10MeV,then to do irradiation with a high-energy electron beam. Its basic principle is as follows: an electron gun emits electrons and injects them into the acceleration tube, accelerated to near the speed of light and then extracted from the titanium window through a scanning magnet.

How does a 10 MeV E Beam sterilization system work, and why does it inactivate microbes?

An electron gun emits electrons into an acceleration tube, where a microwave field accelerates them to about 10 MeV—near the speed of light. The high‑energy electrons are then extracted through a titanium window and swept across products by a scanning magnet to deliver a uniform dose. This irradiation damages the genetic material of microorganisms—causing chain breakage and base loss—so they cannot replicate, achieving disinfection and sterilization. Installation requires a shielding room to contain radiation.
