I could really do something like that very cheaply.
Make it self contained too, so tops of the outsides of the bottles get a wash too.
Have a dump valve to empty,
Fill with clean water for the rinse. Dump
Fill will starsan. Dump back into starsan container to be reused
Yeh, that would be very easy and VERY cheap if I used plastic pipe.
I'd just need the pump (the one I have, now I think about it, doesn't have the pressure required)
A couple of issues with that design or at least what he is using.
The hot water pressure for rinsing 24 bottles at a time will need to be good.
There he is not cleaning bottles so you would need to think about running thru a bucket of cleaner solution.
He says he is using starsan. Starsan is not recommended where soft metals are present, the copper might be ok but the soldered joints could be affected.
I would also fit a drain valve on the copper pipe array so that if you do run a cleaner thru it and then a sanitiser like starsan, then you can fully drain and flush the cleaner out before running starsan thru it as there is potential to produce chlorine gas depending on what you use as a cleaner.
