Abstract
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.
Claims20
A method for roasting coffee beans, the method comprising:
- operating a heat source to generate heat using biomass fuel, wherein the heat source comprises a fuel conveyor mechanism and a furnace, the fuel conveyor mechanism coupled to the furnace and comprising an auger configured to deliver fuel to the furnace, wherein combustion of the fuel occurs in the furnace, and wherein the furnace is coupled to a heat transfer mechanism via a first interface;
- transferring the generated heat, via the heat transfer mechanism, to a roaster mechanism comprising an outer shell and an inner shell, wherein the outer shell is fixed to a supporting structure, wherein the inner shell accommodates coffee beans, wherein the heat transfer mechanism is coupled to the roaster mechanism via a second interface, wherein the second interface is positioned at a bottom of the outer shell of the roaster mechanism and comprises an opening with a sliding door mechanism, and wherein the heat transfer mechanism is removable from the roaster mechanism;
- controlling a roasting process in the roaster mechanism by regulating the heat source and the heat transfer mechanism.
A coffee product, comprising:
- roasted coffee beans;
- wherein the roasted coffee beans exhibit a pH value of 5.3 or higher;
- and
- wherein the roasted coffee beans are substantially free of chemical additives.
