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
An apparatus for processing material, comprising:
- a conveyor unit comprising an auger, the auger configured to rotate such that a quantity of material received at the conveyor unit is caused to be transported according to an axis;
- at least one microwave energy generator operatively connected to at least one microwave guide configured to cause microwaves emitted by the at least one microwave energy generator to apply energy to the quantity of material within the conveyor unit by causing at least some of the applied energy to be absorbed by the quantity of material;
- and
- at least one microwave suppression system associated with a material inlet/outlet of the apparatus, wherein the material inlet/outlet is associated with at least one flexible and/or movable flap,
- wherein the at least one flap comprises a shielding mesh and is configured to absorb, deflect, or block microwave energy.
