How do commercial coffee roasters work?
A hot-air coffee roaster forces hot air through a screen underneath the coffee beans so that heat is transferred throughout. The roasted beans are then cooled in a process known as quenching. The cooled beans are packaged immediately in bags which allow for degassing. They are then shipped to stores to be sold.
