Any thoughts on the breweasy setup?

http://www.blichmannengineering.com/products/breweasy

I'm currently building a similar setup. Just because I already have 2 50L vessels, and a pump and I don't want to be boring.

I'm done with a slap together arduino mash controller. I still need to find a way to have the buttons and display nicely in the enclosure. I'm basically done with the level control switch. And the last thing is to find a way to connect my 3/8 inch counter flow chiller to the 1/2 inch silicon tubing.

I'll post photos once the rain stops.

Neat. I'm assuming your mashtun works with direct heat? Or will you introduce a hlt at some point?

Both vessels currently have heating capacity. But the majority of the liquid will be in the bottom vessel call it a HLT/BK. The pump and flow control switch will controlled the volume in the top mash tun and the PID will keep the liquid at a set temperature.

I really like this idea. Would also consider doing something similar in future.

Looking forward to your photos!

No, the Blichmann system uses one burner under the kettle. So you heat the bottom to mash-in temps and pump your mash volume to the top. Then you mash in. Then circulate from top to bottom by gravity and back via the pump if you want to clarify or step mash. Actually bloody clever.

Neat idea, the 2 vessel brewery. I see breweasy talk about patents but this idea has been on forums a long time...... Search brutus20 - original 2 vessels and 2 pumps on a single tier but on 2 tiers you need only one pump. My brewery is currently 2 SS vessels but no pump, maybe in future.

95% done with everything. It is still an experimental built so it is not very neat. The pump still need a housing and the arduino is still naked.

I'm doing a brew on it tomorrow. I've used fix-all to connect a stainless nipple to the copper counter flow chiller. Hopefully the connection is ready in time.

I'll take photos of the setup using water and during the brew.

Few lessons learned

On the negative:
Oats is a bitch to sparge/recirculate.
The return pipe created a syphon to the bottom kettle when the pump is off. So not a lot of recirculating happened. I'll have to lift the brew bag a little to aid draining of the top kettle with a false bottom of sorts
Realized I made a coding error in the arduino and had to reprogram it half way through the mash. It works well now.

On the positive:
Fix-All is good stuff, zero leaks
Counterflow + pump is a potent combo. Easiest chill since I started brewing.
Brew day was fun

Any pointers on how to do volume markings on a keggle?

@DieBaas can you post some on the arduino, like where to buy, what you need and ... Say if a guide to electrify and automate mash tun in good old RSA.

Sure thing. On my way out but I'll do a full write up when I'm back.

How good are you with programming?

I'm actually going away from the arduino to a esp8266 because it has built on WiFi.

Got trained in turbo Pascal, tried java but then asp came. Used to do a lot of php but lately I seem to drift away from development.

Small grinder with wide grinder disk. You just need to touch the steel with the disk.

I'd mark the level with a permanent marker then zap on the mark.

If you're anal, the earbud & 12v system works if you want to mark the volume using a small stencil as well

Brewed on this setup again last week Tuesday and had much better results but the PID is still wierd.

Made sure there is no syphon and added a false bottom (oven rack) under the bag and it made a massive difference in the recirculation.

@Setsumi, Sorry for not posting the Arduino stuff. The one thing still bugging me with the setup is the Arduino PID. I followed the Arduino Sous Vide cooker instructions on Adafruit. but for some reason the PID keeps overshooting the target temperature and doesn't switch off. It keeps going. While I have no problems with a PID I do feel that it is overkill for home brewing.

I'm trying to get an ESP8266 running with Blynk but instead of running a PID control loop, I'm rather going for an hysteresis with a bit of intelligence.

This wiil make the code atleast 10 times shorter and I doubt that it will be any worse than the PID.

But the ESP8266 Ihave is going crazy. Might have to go with a Arduino with an ESP8266 built on if I can't get it running

This is where it get interesting. Got the Esp8266 running. Added a onewire temperature sensor and built a quick dashboard on Blynk.

Played a little more.

Left the temp sensor running over night

Also added a terminal to export sensor data. This can be exported to csv when brew day is done

Realised now in its current state this will already be a very cool fermentation temperature logger.

https://uploads.tapatalk-cdn.com/20170328/8ac0cfa740a3af8c22fe1993a307857f.jpg

It will be even cooler if this can switch my fridge and log the temperature.

Or maybe I can add a gravity reading to this?

Lots of lessons learned yesterday. Had to redo most of what I've done but everything is much more stable. Also finished the control loops.

A bit of lag between the Blynk interface and the controller. But that can be fixed by installing a Blynk server on my media server.

I'll have to test overshoot amount.

Currently the relay pin out is just triggering a led to test

Next up is to add a simple timer. And then hopefully version 2 will have programmable mash steps.

@DieBaas, I have a 2 kettle gas setup, HLT sub as mushtun and brewkettle keeps my sparge water. But I have to sparge with buckets and I want to do away with it. I am thinking to put a pump in the brewkettle to the mushtun that will drain by gravity into the kettle and circulate the water and wort.
My question, are you happy with your efficiency?
