A roasting device is designed to fit and operate inside a conventional, general purpose, home oven. The roasting device utilizes the heating and exhaust system already in place for the oven allowing the roasting device to be substantially less complex and less expensive than existing coffee roasting systems. The roasting device includes roasting chamber or drum for containing the coffee beans. The roasting chamber has a first and a second end and a substantially cylindrical sidewall. The substantially cylindrical sidewall includes a plurality of perforations uniformly distributed along its length. The perforations allow the heat from a conventional home oven to reach the circulating coffee beans during roasting thereby producing evenly roasted coffee beans. The coffee beans discard chaff during roasting that is expelled through the perforations to a tray positioned underneath the roasting chamber. The first and second ends are substantially concave for preventing the coffee beans from adhering to the ends. The second end includes a lid for loading and unloading the coffee beans into the roasting chamber. The roasting device includes a body or housing that encloses a rotating mechanism. The rotating mechanism includes a shaft for rotating the roasting chamber during roasting, the shaft being adapted to receive the chamber and a drive drum. The drive drum has a spring for winding the spring responsive to a wind up key. A take up drum is coupled to the drive drum for taking up the spring during roasting. A plurality of gears is coupled to both the drive and take up drums for transferring rotation of the drive and take up drums to the drum. An escapement assembly is coupled to the plurality of gears for controlling the rotation of the roasting chamber. The roasting system is preferably made of stainless steel.
