The Hot Liquor Tank
The HLT is basically an old pressure geyser which has had the top cut off. The thermostat has been replaced and can be seen in the bottom left hand corner. The HLT is bolted to the wall and runs into a washing machine pump which can be seen in the bottom right corner. The pump is used to pump the hot liquor in the mash tun either through the mash tun outlet or through the sparge arm. Tubing runs up the front for checking the level of the waterThe Mash Tun
The mash tun is the same as mine, a fifty litre plastic drum which has been insulated and with a copper "manifold" at the bottom. The sparge arm consists of a shower head. The copper piping on which the shower head fits swivels so it can be swung around if need be to recirculate the hot liquor (to ensure a uniform temperature.The Kettle
The Kettle (or copper) in this case is definitely "The Copper" having been made from an old copper geyser. In the picture you can see the kettle is wearing its insulating sleeve, but with the sleeve off its all nice shiny copper ! The picture shows the run off pipe from the mash tun running into the kettle. At the bottom you can see the pipe running from the bottom of the kettle into another diswasher pump, the T piece after the pump enables the hot wort to be pumped back into the kettle at the bottom to create a whirlpool (to aid cooling when the immersion cooler is being used and to assist in dropping all the hot break to the bottom of the kettle) or into the fermenter. The old 2 kilowatt element in the geyser has been replaced with a four kilowatt element.
Record Keeping
I think I taught him well, a blackboard is an intergral part of the brewery for record keeping.
