Metal and wood
The wrecking ball coffee roaster is a domestic utensil made of metal and wood used to roast coffee beans. It has a spherical container moved by a lever that is slowly spun while the container is supported by a base under the fire. The circular movements aim at a homogeneous roast process. It also has a second wooden stem that is used to open the container when the coffee is on its ideal roast moment, which is generally identified by the color of the smoke.
This equipment was donated to Museu do Café on 2004 by Hercílio Amaral Neto.
