Trying out a fluid bed coffee roaster concept

Tije is trying out some concepts for a fluid bed coffee roaster. A variac is regulating the power for the blower and in the pipe between blower and beans there's a heating element out of a paint stripper. In this setup, the blower seems powerful enough but the heater isn't. We might need to scale down the container holding the beans and aim for 500-600g of beans to roast in this way. We might also order another blower, one with less air speed but more 'static pressure'. And less noise ;-)
