Hello and thanks in advance for any and all help with a project I am working on. Specifically heat control. I am building a fluid bed coffee roaster. It works by roasting the green coffee beans using hot air. The heated air is provided via either electric or gas fired heat being blown over them by a blower fan. My particular project uses electrical heating elements that use 220v AC and each running at 6k I will be working off of a 40 amp dedicated breaker. I am wanting to control the level of heat with a potentiometer. This would allow me to raise and lower the output temp as the beans are roasting. I need help assembling the correct components and maybe some help wiring it all up.
