Hi Mal,

How are you envisioning the pulp exiting cement mixer once it's
juiced?

I'm not sure I'm following your thought.

I'm just spitballing but you could cut a
hatch into the mixer or you could just
pump it out. Or to get really creative
you could use a hydraulic lift to lift
up the fat end.

Mal,

Spit-balling was exactly what I was looking for; at this point I can't
follow where you're going this, I need to feed an acre of 12' stalks
into a device and have the juice exit in one place and the stalk pulp
in another, I can follow how the stalks would be juiced with this
idea, and how the juice could exit the mixer through small holes, but
the problem I see is with feeding and the pulp.

I suppose the pulp would eventual fill the mixer and spill out the
front, but feed an acre of 12' stalks seems like a slow process.

Am I misinterpreting your idea???

Nope, you pretty much have it.

Seems to me that any device that works
to your spec is going to costly or
complex or involve lots of labor.

I believe that I might concentrate on a
cheaper/simpler batch process and plant
my crop so that it ripens every week or
so. Is there any advantage to processing
your crop in one fell swoop. That's got
to add a level of cost (and as I
previously stated complexity) that seems
(to me) unnecessary.

Mal,


In the sub-tread with Jim, we're looking at two potential designs
(hammer mill and roller), both of which of which meet my spec, I
remember seeing inexpensive cement mixers at Harbor Freight 220.00 on
sale from 300.00. I would think the hammer mill may be in that range,
not yet sure about the roller mill.


Harvesting and processing Jerusalem Artichokes into ethanol is pretty
time sensitive, I don't think a batch vs. continuous press would be
the best trade-off, even if a continuous device cost 50% more.

Good spit-ball, but I don't think it's right for me.

Thanks, for your time anyway.

Curbie
