Do you plan to make any changes from your last build? Cement board heat chamber again?

I'll have a new, different blower to design around, but otherwise only slight modifications, especially how the hopper sits on the heater. The hopper will have a wider base and sit shallower in the roaster top. Other than that, pretty much the same.

The vacuum motor came with a rubber 'shock' mount and a plastic cover. I figured it could help with reducing noise. The inside will be lined with 1.5" rigid industrial fiberglass.

Looks great!! Is that main housing right-side up?( I'm trying to figure out the dark area hidden behind the blower.) .. Very cool. - Scott |

Right side up, no dark area - it's an optical illusion. There are two black rubber 'bushings' on top, and you're seeing the two square openings to the motor.

The new roaster is 'finished' awaiting decent weather for a test roast.

Nope. I was hired to make one like mine. I didn't cut quite as many corners since this was a paying customer.

Very Nice! I hope it was profitable as well!
Had you considered a leasing program in the future?
You retain the asset,... steady income(longterm)...scheduled maintainance program,..upgrades, yada,yada,yada. ....I'm jus' sayin'...
-Nice machine! -Scott |

you could go to the lumber yard and get one of them little pagoda style post toppers and drill some holes in it add some screen wire on the inside to top the bean hopper with.
no legs, hows it gonna walk off in the middle of the night.
if you put a flap inside that is hinged so when you flipped it in to partially close off the hopper you would have an automatice bean dump.

That reminds me... I have to put a HANDLE on this one. I mishandled pliers dumping my hopper the other day and lost a pound of 435F coffee on the ground.

Profitable? I dunno yet... spent all the money he sent for parts, but I'm several hours over my original quote... so I hope he's not too frustrated that my guesstimate was off.

I'm sure it did. Have to wait 24 hours so I don't blow it again. Retest tonight.

A bar was required across the hopper to keep it from losing heat flowing underneath - the hopper would bounce on occasion from the pressure under 1.2 kilograms (2.65 pounds). Also had to redo the hole pattern. It had the correct number of 1/8" holes, but the holes were spread out over 4 square inches. I had to condense the same number of holes into about 2 square inches for the coffee to circulate properly.
After all that, the roaster can roast 2.65 pounds to second crack in just under 20 minutes. It can roast 1.75 pounds to second crack in 14 minutes.
Hope the customer is satisfied because the next step would have to be adding heat element(s).
