I had an idea to help increase efficiency and get the most out of the grains for a typical 5 gallon batch. When I look at the grain bed in the mash tun, theres quite a bit above the water line and unless you can continuosly stir the grains, my thought is that there will be some loss. So why not have either a "false top" to keep the grains below the water line or something like a pump to circulate the mash?
Another thought is to maybe have an aquarium water pump to continuously take the wort from the bottom of the tun and with a sparge arm or false top to spread the wort on top of the grains for the whole mash process before the sparge. This would be enclosed in the tun to prevent heat loss.
Thoughts, experiences?
