Hi ikonos,
One thing bothering me is your ref to a grain dryer and roaster

Why?
That's the first thing that's throwing me. I mean, when you buy your barley etc, it has come, originally, from a grain merchant who will have dried it to make sure it doesn't develop mold from being damp and as for roasting
Plus, as a brewer you will, presumably, be buying malted grains so you definitely don't want to be drying or roasting them
Most HBS that supply grains offer a range of malted and un-malted grains in different grades, types and degrees of roastiness from pale to amber to black. Here's where I buy mine from
http://www.thehomebrewcompany.ie/grain-c-69.htmlAll nice guys there, and while no good to you for actual supply, given that they're in Ireland, it may point you in the right direction about the need to dry and roast grains and where to source supply near you, even if you are near a loch
There are a few members here from Bonnie Scotland who do grain brewing and may be able to offer specific help on sourcing malts in the highlands.

I'm sure they'll chip in soon too
As P said, drawings, sketches, etc would be a great help in trying to see where we can provide any assistance or advice. There's a lot of technical know-how on here so I'm sure we can rustle up the help you need if you provide enough info for us to go on
