Krrrazzzy Idea. Prolly.
Responding to another thread for a guy who doesn't have access to rice hulls I suggested back to back batches and the re-use of the draff (spent grain) for a alternative to rice hulls in a potentially sticky mash.
Good or bad, right or wrong, the thought occured to me that while rice hulls are cheap for me ($2.00 for 4 lbs) they are quit possibly an unnecessary expense given that with every brewday I am left with several pounds of material that gets sent to compost. So I ask,
How would one go about drying the draff and avoid lactic souring?
Would a forced air hop oast suffice?
Is this even feasible? If yes, do you suppose it may be benificial to rinse this draff hot to force tannin extraction, remove as much bacteria, and sugar as possible to avoid issue with re-use?
Or should the draff be rinsed with a pH stable (adjusted) water to mitigate tannin extraction?
A lot of questions and possibly in the wrong forum but, lay it on me.
