popcorn, food, coffee, flavor, profile
The goal of this project is to modify a home popcorn popper with computer aided logging of the roasting profile, supported by solid state switching of the heating coil and fan to control the temperature inside of the roasting chamber, and finally, automatic control of the roasting chamber temperature through a PID algorithm. With this control over the roast of the coffee bean, an experienced roaster user is able to identify the stages of the roast where control over the temperature inside the chamber is most critical. As compared to roasting green beans in an unmodified home popcorn popper, this project gives a coffee drinking connoisseur a hands-on appreciation for the development of the flavor profile that is unique to each brewed cup.
