An apparatus for accelerated or controlled degassing of roasted coffee. At least one of the contact partners includes an electrically conductive material that converts to a liquid aggregation state at a predetermined temperature threshold. Each transistor has a control terminal and a current path coupled between the output terminal and a respective circuit element of the plurality of circuit elements. The frame supports the weighing conveyor, the load cell, and the movable member. The objects contained in the list can be selected individually for a laser processing procedure.
