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.

Electric fluid bed roaster cart build
New to the forum. Decided i could build a roaster alot cheaper than what's for sale.
Specs so far
5200 watt dryer heating element looks like there is 3 separate elements in it.
4qt funnel with 3 inch opening
5 inch to 3 inch reducer
5 inch 90 degree elbow
Harbor freight 2 shelf cart
MASTECH dual probe thermometer
Temperature controller with SSR
Stainless steel perforated basket for bean cooling.

Need a vacuum/blower, and variable ac controller. Here's the pics of whats actually assembled so far. Also planning on putting side panels on hinges for easy access to internals.
Any suggestions would be appreciated.

Looks good! You should be able to roast around 1kg with 5200W.

Is the 5 to 3 reducer galvanized?
Yeah I'm going to strip it this is a rough fitment so far, wanna make sure everything works beforehand
How many cfm's should the blower be to move 1kg of beans?
I'll let others answer CFM questions.

I have no idea what mine requires. I will say that use a 600W vacuum blower from a cheap stick vacuum cleaner and it is capable of over 1kg given the right RC design.
CFM isn't important and is mostly impossible to measure without lab grade meters. What's important when not using vacuum motors is static pressure. Must be over 10" H2O and wattage must be over 500 watts or, if 120 volts, over 4 amps if wattage spec isn't available.

If using a vacuum motor, the only spec that matters is wattage. As Brad mentioned in the previous post, 600 watts gets the job done with ample headroom for a 1kg done properly.
