Tom and Julio dug deep to do some maintenance on our Probat B3 sample roaster. This is the machine we use to roast small amounts of the coffee in order to taste them for quality control. It’s made of extremely durable materials but still needs some TLC in order to keep roasting coffee properly.
Once is a while, this robust chunk of heavy metal needs to be cleaned up and brushed down to get rid of all the oil and Chaff is paper-like skin that comes off the coffee in the roasting process. Chaff from roasting is part of the innermost skin (the silverskin) of the coffee fruit that still cling to the beans after More dust build up. The electric burners need to be maintained as well. In this instance, a metal staple fell onto the coil and damaged the entire burner. Luckily, there is a company that produces the necessary parts for the repair.
