I got a Roestmeister unit and have discovered now that the "required" beans
are pretreated in some way to remove the skin.
This is also an ongoing requirement. The beans are not available locally so
a work round for this is required.
It may be a matter of creating a medium mesh or gauze shield of some sort to
stop dross going into the heat sensor at the air outlet nozzle. To stop
fires and that part getting clogged.
The supplied beans sure did not "chaff" but green beans of the same sort;
locally purchased, sure issued forth. We used a heat gun on very low heat
and speed to blow skins away and then as well used a vacuum cleaner to suck
them up as they were produced. Not sure which if either may be the best of
those options for the job over time.
Best would be to find a way to treat the beans to remove the skins.
Has anyone tried this or have a try out method please?
There is also the consideration that blowing or sucking as the unit is
working may interfere with timing cycles by changing the heat entering the
heat sensor reading area. This is adjacent to the air gun nozzle.
It seems the treated beans are a bit larger after processing. Small (local)
beans fell through the mesh and that makes me think the "treatment in some
ways makes the beans swell in the process of removing the skins.
Anyone have any ideas on this please.
In fairness I must say the supplied beans finished nicely. Also the local
beans with an attempt to remove skins before entering the sensor area came
out well enough too. I used the medium setting for reference. Some 10
minutes according to the booklet.
I was not sure how much I may have been altering the heat reading for the
sensor and so was very pleased to see the comparison beans did quite well.
Over all a good unit but with the "hook" that specially treated beans are
required. They are available from the Roestmeister suppliers of course.
Now how the trick is how can one treat ones own beans locally.
