This year’s updates have been related to an idea I’ve been sharing for recirculating mash systems involving a high flow loop within a brewery’s plumbing
During the craziness of the holiday shopping season, one of my favourite homebrew equipment and ingredient suppliers, Ontario Beer Kegs put their false bottoms on sale… I’d been eyeing up one for awhile and couldn’t resist ordering one even though it wasn’t officially designed to fit my mash tun.
The core of an all grain homebrewing system is arguably how the mash process is completed. Here I describe and compare 7 popular homebrewery designs based on this property, all of which are capable of making great beer.
When I initially designed my brewery, I did so with keg cleaning in mind. The C-HERMS (Counterflow – HERMS) brewery design was partially motivated by an opportunity to purpose the dual pumps for sanke keg clean-in-place. This ended up being a complete failure.
Proper specification of PID controller settings ensure that target temperatures are met quickly but not overshot, and cycling of temperature, or more formally, the process variable, is minimized. In an electric brewery, PID settings will be system specific, and will be especially determined by element wattage, liquid volumes, recirculation speed, and other environmental variables.
