System and method for roasting coffee beans
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.
1 . A coffee roasting system, comprising:
a roaster mechanism comprising an outer shell and an inner shell, wherein the outer shell is fixed to a supporting structure, and wherein the inner shell accommodates coffee beans;
a heat source comprising a fuel conveyor mechanism and a furnace, the fuel conveyor mechanism coupled to the furnace and comprising an auger to deliver fuel to the furnace, wherein combustion of the fuel occurs in the furnace;
a heat transfer mechanism coupled to the furnace via a first interface and 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 allowing heat from the heat source to be removed from the roaster mechanism; and
a control module coupled to the heat source and roaster mechanism.
2 . The coffee roasting system of claim 1 , wherein the auger rotates and delivers fuel to the furnace.
3 . The coffee roasting system of claim 2 , rotation of the auger is controlled by the control module.
4 . The coffee roasting system of claim 1 ,
wherein the inner shell is coupled to a motor which causes the inner shell to rotate; and
wherein the motor is controlled by the control module.
5 . The coffee roasting system of claim 1 , wherein the control module is in communication with one or more sensors which collect one or more telemetry signals from the roaster mechanism, the heat source, or both.
6 . The coffee roasting system of claim 1 , wherein the control module comprises a communication module coupled to a network.
7 . The coffee roasting system of claim 6 , wherein the communication module is in communication with a server to download a roasting profile, and wherein the roasting profile indicates a set of roasting parameters for a roasting process.
