For those who know me here and have followed some of my various ideas, blogs, threads, and other rants/comment/mumblings dealing with homebreweries, you will know I used to be building toward this:


that thread can be found here. I loved brewing on the system and all the concepts were proved. However, I didn't have the money to get it fully setup and running with automation and the whole-9. So I sold it to a member from HBT... dun dun dun...

Meanwhile, I designed a smaller scale system for a friend. He has called his brewery the Simple Brewery. It is a design based on Brutus 20 (Lonnie Mac) and the Countertop 20 (Jkarp) with a few changes. I call this design the Twent-E2 (pronounced twenty-two) because it is a two vessel system that is fully electric and two-tier.



Here is how the Twent-E2 works:


The Simple Brewery is almost complete. You can see the build and progress here.
.................................................. ........................

Now that you have some history, here is the present build idea.

This design is called the 2P-Twent-E. It is a single-tier, two vessel system with two pumps, all electric, and runs on 120 VAC (20amp). The beauty of both 2P-Twent-E and Twent-E2 (like the countertop 20) is that they can be run anywhere that has 20 amp power (any kitchen or garage generally).

Here are some concept drawings:

Here you can see the MLT on the left and the boil kettle to the right. Both the MLT and the BK have pumps directly connected to their outlets. All fluid flow will be pumped. A RIMS heat exchanger tube is positioned on the output of the MLT and a HERMS heat exchanger coil is mounted in the BK lid. Both vessels have returns.


This view gives you a peek into the kettles. The MLT has a full false bottom and a return that will have a loc-line hose (not shown). You can also see the electric heating element (2000W HD 120VAC).

This is a view from the back and shows the return and pick up in the BK. It is setup to whirlpool while chilling.


A better view of the connections in the MLT.


And to give you some scale, I am 5'9". The stand will be a stainless topped equipment stand, 32" by 60" top and 25" tall.


The kegs are rubber coated for added insulation and because they look awesome. The control box looks like a toolbox because it is.

and here is how the 2P-Twent-E will function on brew day:



and here is the wiring diagram for the box:


For those code minkeys following the Simple Brewery thread, I changed all of your suggestions. I bought a flanged recessed male outlet ($17.00 thank you very much), bought covers for all the terminal blocks, and am using insulated grounds. I have also made solder grounds to all sections of the box and there are no pumps inside anymore.

I hope that makes sense. I will save a bunch of posts after this first one for pics updates and whatnot.
