Abstract
Systems and methods for drying asphalt shingle waste are provided. A method comprises obtaining an asphalt shingle waste, exposing the asphalt shingle waste to microwaves emitted by a microwave dryer, and processing the asphalt shingle waste into a processed asphalt shingle waste. The asphalt shingle waste has a first moisture content at an inlet of the microwave dryer. The asphalt shingle waste has a second moisture content at an outlet of the microwave dryer. The second moisture content of the asphalt shingle waste is less than the first moisture content of the asphalt shingle waste.
Claims20
A method comprising:
- obtaining an asphalt shingle waste;
- feeding the asphalt shingle waste at a first temperature to an inlet of a microwave dryer;
- exposing the asphalt shingle waste to microwaves emitted by the microwave dryer;
- discharging the asphalt shingle waste at a second temperature at an outlet of the microwave dryer,
- wherein the second temperature is a temperature of 140° F. or less;
- wherein a moisture content of the asphalt shingle waste at the outlet of the microwave dryer is less than a moisture content of the asphalt shingle waste at the inlet of the microwave dryer;
- and
- processing the asphalt shingle waste.
A method comprising:
- obtaining an asphalt shingle waste;
- feeding the asphalt shingle waste at a first temperature to an inlet of a microwave dryer;
- exposing the asphalt shingle waste to microwaves emitted by the microwave dryer so as to reduce a moisture content of the asphalt shingle waste;
- discharging the asphalt shingle waste at a second temperature at an outlet of the microwave dryer,
- wherein the second temperature is a temperature of 140° F. or less;
- wherein an average particle size of the asphalt shingle waste at the outlet of the microwave dryer is within 10% of an average particle size of the asphalt shingle waste at the inlet of the microwave dryer;
- and
- processing the asphalt shingle waste.
A method comprising:
- obtaining a plurality of briquettes,
- wherein the plurality of briquettes comprises an asphalt shingle waste;
- feeding the plurality of briquettes at a first temperature to an inlet of a microwave dryer;
- exposing the plurality of briquettes to microwaves emitted by the microwave dryer;
- and
- discharging the plurality of briquettes at a second temperature at an outlet of the microwave dryer,
- wherein the second temperature is a temperature of 140° F. or less;
- wherein a moisture content of the plurality of briquettes at the outlet of the microwave dryer is less than a moisture content of the plurality of briquettes at the inlet of the microwave dryer.
