I rarely purchase roasted coffee. I just ordered 4 bags from Mountain Air Roaster.

Hi, I use a wok with a glass lid for roasting. shaking the wok is a good exercise, actually.

ceramic infrared element
matt
Good Day. I have been roasting for a year or so with a modified ronco 4000 rotisserie. It is a bit tired so I am building a new one based on the ronco 6000. I am hoping to roast a five pound batch. My question is about the type of element to add. I noticed one of the models crc roasters builds used what looked like ceramic infrared elements. If someone has some pros or cons on this I would appreciate it. Thanks Matt

What roasters do you mean? please, can you post example(s)?
IR on drum, or IR directly on beans?

Asking because these are extremely rare builds, I can count under 5 here since I monitor this forum, and most are halogen, none is ceramic. I mean IR directly on beans.

IR is the cleanest and best efficiency heat source, but the main issue is how to dose it... effects are hard to measure, and variable absorption while the beans color change.
Also, you need a good than average agitation, because IR is like sunbath, beans must be as equally as possible exposed on all sides.
DIY: TO based IR to bean 750g
Moded commercial: Dieckmann RoestMeister, Nesco, popcorn.
TC4ESP, PID controllers, MS6514 USB/Artisan/Apps
Grinder: MBK Feldgrind, mod'ed Porlex to 47 conical burrs, vintage PeDe Dienes

My favorite IR emitter is the ceramic long wavelength. Easy to mount, very durable and every configuration you would ever need. Pros are durability and ease of installation.
