A fluid bed coffee roasting system is disclosed and configured for roasting batches of coffee beans of varying sizes. In at least one embodiment, the system provides a roasting unit configured for roasting a volume of coffee beans, a chaff collection unit positioned and configured for drawing off and capturing any loose chaff released by the coffee beans within the roasting unit, and a cooling unit positioned and configured for receiving and cooling the coffee beans after they are removed from the roasting unit.

A system for roasting particulate material, such as coffee or cacao beans, grains, malt, said system comprising: a photovoltaic unit configured for generating electricity from the solar radiation; a heat storage device comprising at least one phase change material; a roasting device configured for roasting said particulate material; a thermal circuit connecting the heat storage device to the roasting device, and configured for circulating a fluid through the roasting device; and an electrical circuit connecting the photovoltaic unit to the heat storage device, and configured for exchanging heat with said at least one phase change material.

A coffee roasting system is provided. The system includes a roaster mechanism with a container for accommodating coffee beans. The system also includes a heat source configured to produce heat. The system further includes a heat transfer mechanism comprising a first interface which can be coupled with the heat source and a second interface which can be coupled with the roaster mechanism. The second interface is configured to allow the heat transfer mechanism to be disengaged from the roaster mechanism. In addition, the system includes a control module coupled to the heat source and roaster mechanism and configured to control the heat source and roaster mechanism.

Disclosed is a roaster/roasting machine for roasting an edible plant such as coffee beans. This roaster/roasting machine comprises a roasting chamber for containing a substance to be roasted, the roasting chamber being made of a carbon material (graphite, CC composite, etc.). Thus, the roaster/roasting machine can utilize far-infrared rays for roasting with a simple structure. A roaster comprising an open top container body and a closure member may be used for home roasting. A roasting machine comprising a drum-shaped roasting chamber may be a professional roasting machine. The present invention can be applied to any of a direct-, semi-hot air-, and hot air-heating type roaster/roasting machine. Also disclosed is a method for roasting beans such as coffee beans, the method comprising contacting beans with a heated graphite.

A bean roasting system includes a roasting chamber, a blower, a variable diverter and a controller. The roasting chamber, the blower and the variable diverter each is disposed at least partially within a recirculating gas flow path. The blower is configured to provide a flow stream of gas through the recirculating gas flow path. The variable diverter is configured to split the gas flow path into at least two flow paths including a treated flow path and a bypass flow path. The treated flow path includes a series arrangement of a gas heater and a catalytic converter. The variable diverter is configured to control a percentage of a flow stream of gas that is diverted into the bypass flow path. The controller is configured to activate different predetermined operating modes for the bean roasting system by controlling a state of the variable diverter and a state of the heater.
