DIY Randall the Enamel AnimalWho is Randall? Well he's Randall the Enamel Animal. Still don't know? It's an organoleptic hop transducer module. So... What's that?
- Two (2) Pentek 158117 filter housings
- Four (4) 1/4" NPT to 1/4" Nipple
- Northern Brewer Foam Free dispenser tubing for Ball Lock Keg (5ft of 3/16" beverage line with a picnic tap on one end and a ball lock liquid out disconnect on the other)
- 1" ID x 10" long tube (Stainless Steel, Copper, PVC, other food grade material, etc.). We used the inside spear of a Sanke Keg.
- Teflon Tape
- Worm Clamps
- Pressure Relief Valve (something similar to a Powermate 150 PSI Valve would work)
Step 1:Teflon tape and screw 1/4" NPT fittings into filter inlets and outlets.
Drill a few small holes into the top of your metal or PVC tubing and insert it into the first chamber in the series. This will allow the beer to flow out of the keg, into the filter housing, up the tubing and cascade over the Randall ingredients.
Mount you Randall so it stands upright and is secure. We simply put 4 screws through a piece of plywood and into the built in inserts made to mount the housing under a sink.
This is the only step that requires some skill. To ensure there is no foaming and to properly regulate the level of liquid in the actual Randall, you are going to want to install a pressure relief valve. To do this, drill a hole in the top of the Randall (bottom of actual filter housing) which will allow you to thread into the housing with the pressure relief valve.
So what should you Randall? What shouldn't you Randall? Randall hops, fruit, cookies, donuts, oak chips, vanilla beans, hot peppers, bacon, spices, etc!
