Hello Everyone,
I am currently drafting a business plan for setting up a small micro and am looking at brewhousee options. One of the things that I see very commonly in turn key solutions is a 2 vessel setup. For my understanding the vessel are multiple purpose as follows:
Vessel 1: Mash tun/lauter tun
Vessel 2: Kettle/whirlpool/HLT
I also they are feed by a tankless water heater to supply hot water on demand. The advantages to these types of systems that is often described in reduced space requirements and initial setup costs, due to no need for a HLT or a dedicated whirlpool.
To me the combined Kettle/Whirlpool makes perfect sense, as there is only small gains in terms of geometry with the biggest impact being batches per day which will likely bottle neck elsewhere anyhow.
However I am having trouble working out how this type of system works in terms of the sparge process and specially how a tankless heater provides a supply of treated water. I can conceive how mashing works; you fill the kettle with treated liquor, heat to strike temperature recirculate to preheat the MT then, mash in. The HLT at this point is now empty.
The confusion I have is when you precede to sparge, as the kettle is occupied receiving runnings from the MT/LT and can't double as a HLT. This means further liquor will need to be supplied at sparge temperature from the tankless water heater.
So where does water treatment for sparge liquor take place? In understand treatments with salts can all be applied during the mash, but you will still require de-chlorination, potentially demineralization and acidication for sparge water, something that as far I can tell is usually by nano-filtration or RO and not something that can be done inline (not that suppling the plant with RO inline would be a good idea anyway).
So this begs the question do you need to feed the tankless water heater from a Cold liquor thank filled from your plant water treatment? in which case I fail to see how it saves space. Alternatively if you have a fast flow nano filter and inline acidification this is also likely to be significantly more costly than a slow flowing system with a CLT.
Is there something I am missing?
Thanks
