Over the past months, Tije has been testing out several concepts for a fluid bed roaster that will be very similar to my Fracino Roastilino but with a larger capacity.  One example is shown here: A problem in this setup is the high speed of the cheap blower we are using. The blower is so powerful that it cools the heating element rather than heat the beans and it tends to blow beans all over the place instead of just "stirring" them around. We actually need a blower that has less speed with more static pressure and we're currently looking at an Multi Stage MS8 Backward Curved, Single Inlet Centrifugal Fan from Air Control Industries.
