Okay, pictures:
Picture of the PicoBrew from the front, filled with 8.75 Lb of grains for this weekend's brew. Limit is 9lb.
Picture of the unit from the front with the step-filter removed. The step filter connects to the unit via the small tube at the bottom center. Wort is circulated into the unit via a movable fluid arm that's barely visible at the top center of the compartment.
Connections on the side of the unit. The "out" hose, forward has a sample port that fits a syringe. The "in" hose, rear, has an in-line filter.
Step-filter from above with lid. You can see the four holes at the top of the picture where wort is circulated through the hops cages during the boil. The hole in the lower center of the picture is where the wort is circulated through the grain during the mash cycle.
Same thing, no lid. There's a mesh screen on the top and bottom of the mash compartment, and another one under the hops cage compartment. They're pretty sturdy tig-welded stainless steel.
Hops cage
Another of the hops cage.
Step filter from the side.
And the step filter from the rear. You can see the port where the filter connects to the corresponding tube at the bottom center. Also the 4 hops cages sit in their own container. During the boil wort is added to the proper cage. Any cage beyond the first, it waterfalls to the previous cages before returning to the keg and recirculated.
I hope that's helpful! Pictures of beer later when I open them. Feel free to ask questions!
