Abstract
A continuous asphalt mix system for using a microwave heating vessel at the point of production that includes a microwave energy suppression tunnel with one or more mesh flaps for substantially reducing or preventing the leakage of microwave energy from a microwave system, while having a continuous flow of product through the vessel and suppression tunnels. The suppression tunnels are installed on the inlet and/or the outlet side of the system and are sized to suppress leakage.
Claims20
A microwave suppression system, comprising:
- a tunnel associated with a material inlet or a material outlet, the tunnel comprising at least one flexible and/or movable flap comprising a shielding mesh,
- wherein the at least one flap is configured to absorb, deflect, or block microwave energy, and
- wherein the at least one flap is configured to be deflected as a material passes through the tunnel and then to return to a resting, closed position when the material is no longer passing through the tunnel.
