So I'll becoming back from Afghanistan soon and I've had a while to think about exactly what I wanted in a BIAB stand. I went with a BIAB recirculating setup (for the mash and IC whirlpool) and an electric winch attached to lift my BIAB basket. This is what I came up with:
It just a quick sketch but I think you get the idea. The pump output will go to a cut and bent piece of copper tube that hangs inside the pot. It will be adjustable in height for different batch sizes and the output will run along the inside wall to create a whirlpool. It will be easily removable via a clamp.
The winch is bottom mounted and runs to the hoist frame via 1 pulley and an eye bolt. The hoist frame free swings to help center the cable on the pot and allows me to drop the basket in a bucket to the side. The load should stay centered on the stand to avoid tipping. The mast fits inside a larger tube so it can be lowered when not in use.
Heat is done with a SQ14 burner and 20lb propane tank located under the pot.
Cooling will be done with a copper 60' IC with whirlpool and copper 40' ice bath pre-chiller. The pre-chiller in a cooler will sit on the wooden work area. All connections will be via garden hose quick disconnect for an easy switch to the pre-chiller.
A simple control panel will be installed for the wort pump, pre-chiller pump, and winch control.
Besides being made of 2x2 square tube you see:
This will be my first attempt at a rig so let me know what you think. I'll be starting on this sometime in October.
