That my friend is the top of the line most complicated dream to have system for homebrew. It's a RIMS (Recirculating Infusion Mash System)
The tank on the right is a HLT (Hot Liquor Tank) made from a converted 15 gal keg. This tank holds and maintains hot water to achieve strike in, step, and sparge/mash out temps in your MLT (Mash Lauter Tun), that's the tank in the middle also made from a converted 15 gal. keg. This middle tank has a false bottom or manifold to filter the wort from the mash.
The last tank on the far left is the boil kettle. It too is made from a converted 15 gal. keg.
The way the system works: The HLT is filled with water to be used for mash (adjusted if necessary) the fire is lit under it and it is heated to your strike temperature. By opening valves in the piping underneath and activating the pump (in the black box on the right) You can pump the water over to your MLT to mash the grains. Now, to maintian temperatures in your mash and to achieve better filtering by the grain and clearer wort, you close the valves that sent the water in and open the valves that recirculate the wort through a coil that is in the HLT. This pulls off the bottom of the MLT and circulates it through the coil in the HLT maintaining temperature as it does and deposit's it back on top of the grain in the MLT. To complete mash, increase to mash out temps and sparge.
At the end or your mash, you open the valve that drains over to the boil pot and collect your wort while sparging. Once you achieve your boil volume, you boil, add hops, irish moss, yeast nutrient at specified time schedule and then cool the wort before transfering into a couple of 5 gal carboys. (This puppy will do 10 gal at a time.)
Pitch yeast and firment as usual.
