It's Alive!!!

Hot liquor tun on the left, mash tun on the right

Valves are configured to recirculate the mash.  They were configured to fill the mash tun with water from the hot liquor tun.

Heat exchange coil in the hot liquor tun.

Water coming out of the heat exchange coil and back into the mash tun.

Dump valve open, used for priming the pump and pumping wort to the boil kettle.

Valve and pump assembly removed from setup, reinforced vinyl tube and hose clamps make disassembly simple.

Coolers disassembled and ready to be put away.

Still need to add temperature sensors at key points, hook the temp sensors to the web controller, hook the the element back up to the SSR and hook up the web controller.  Still some programming to do to control the web controller with the web browser.

Change of Plans

I decided to go with a single tier design for the brew system. Having the heat exchange and the mast tun on the same level will improve the potential of the pump. I have a 1/40th hp circulation pump and I am a little worried about how well it will perform.

In this schematic V1 - V5 are valves and P1 is the pump.

I've also made up a list of system processes and corresponding valve configurations, I will post those later.

Boil Kettle Circuit Part 2

That's it?

After trying a couple of times to have someone build the boil kettle circuit, I finnally decided to try it myself. Shown below is the bare bones of the project. The blue twisted wires go to the solid-state-relay. The brown twisted pair is the DC power. I plan to box it up of course, but am still deciding if it will be part of the fixed control panel, or have the dial as some sort of wired remote.

By the way it does work. Turning the pot to the left reduces the on-off cycle to completely off, turning the pot to the right increases the on-off cycle to become completely on.

Want one? Let me know, we can work out some sort of trade. -TC
