I want to put a big bag over a powerful fan to dry a big volume of material by air (pic related).
I get that I need a centrifugal fan, but I have no idea if I need more airflow for this task or more pressure, or how much of those I would need to achieve.
The material in question is wheat bran, at about 30% moisture content, fluffy, not sticking to itself, fairly voluminous - 3-4 liters/kg, an I'd like to dry at least 50kg of it per cycle.
A voltage dimmer on the motor sounds good, but yeah, no idea which fan I need.
