Thread subject: Homeroasters.org :: Probat pictures, anyone?
Posted by Lawnmowerman on 04/28/2012 23:36
The local roaster where i purchase my green beans has graciously agreed to let me take pics of his roastery. He has a 25lb capacity and i think 250lb capacity probat gas fired for both. The larger has afterburner. Any interest? If so, any specifics that you would like to see detailed shots of? The shop will be dismantled shortly to move a few blocks away. Seems a bit daunting but if there is a need...

Of course we are interested... and pictures of everything

Internals of drums and burners would be nice.
In addition to pics please ask about heat controls for each of them. Specifically, on smaller one is it gas valve throttled manually or multi-staged?
On larger one, manually throttled, 3 stage or pulsed (proportional on-off.)
Seems the larger gas fired roasters are still a bit of a mystery on controlling the roast.

Brew a man a cup of homeroasted coffee, you spoil him for a moment or two. Teach a man to roast, he is ruined for life.

One more of the l12. Gas is throttled manually. The remainder i have for now are of the big one.

Here is where the beans are loaded. Up to a hundred pounds

The blower behind it pushes the beans up the chute into this hopper. Blower also provides convective flow in the drum

Gas controls are three stage for this one.

Tried to get an internal shot on this one but poor lighting

The bottom of the afterburner. And some of the control machinery

The bean cooler. Too bad the one i have with it full of beans is of too high a resolution.

The column in the forground is one more vacuum conveyance to get it to the last hopper, elevated so as to allow the rolling bins to park under. It takes them from the destoner, positioned at the trap door output of the cooler. A hundred pounds totally hands free!

The damper. Has three settings. Can only be run wide open or the afterburner smoke alarm goes off. On this setup. Designated as espresso setting.
