The Coffee Roaster


The designed fluidized coffee roaster included controllable dials that allowed users to control the roasting temperature and the airflow. This enabled an excellent roasting experience. In addition, it had a cooling unit that allowed users to easily cool down the roasted coffee beans to the desired temperature within a given time period. It also had a chaff collection unit.

Our Rules:

Conceptual Design

The designed Outlet Cover including the Stamp Terminal had a universal inlet that allowed the PCB to manage the consumed electrical current from the plugged-in device. In addition, it allowed for objects with a known range to protect children and to protect the system from the overload.

CAD Design

CAD development was carried out to refine and enhance the modular design for the coffee roaster. Time was spent developing a roasting journey to make it easier for the users to roast the coffee beans, to cool down the roasted coffee beans efficiently, and get the chaff collected effectively.


A series of prototypes were created using a combination of CNC mechanisms, laser cutting, 3D printing, and sheet metal bending to allow the fluidized coffee roaster to be tested and refined before creating the final product for commercial usage.


When I started the process of implementing the coffee roasting machine (Mihmas) I was really surprised to find a local industrial design firm that can help in designing and prototyping the machine as I was lost with nowhere to start and with their support we managed to translate the idea into a working model. With the coffee roasting knowledge that I have from my coffee roasting business and the engineering knowledge of the team we have worked together to control the design aspects of the machine so that it fits the exact requirements of coffee roasting.
