Default The braumiser, my braumeister inspired rig

I have been wanting to build a small batch brewery for a while now so last year I started to build a 9 liter (2.5 gal) braumeister style rig. I started off with a 20l ( 5.3 gal) pot which i added 3 feet to and a center rod. I then added a 1.75 kw low density (35w/square inch) electric element and a pump, I first started off with a small 12v pump that said it was made out of food grade plastic but after a couple of uses there was still a strong plastic flavor and smell coming off it so i changed to a march pump. I made a controller based on a PIC 18F2520 microcontroller and i programmed it to follow the braumeister controller. There is basically 3 selections, manual, auto and setup, in manual mode the temp is adjusted by the up and down buttons and the pump and heating elements are turned on and off by the enter and start buttons, this allows you to control it completely manually but with a PID algorithm controlling the temperature. The auto mode runs off a preset number of steps that is entered in the setup menu, there are 6 steps available, a mash in step plus 5 others, a boil time of up to 2 hr. I have deviated from the braumeister by adding 5 hop addition alarms, a delay start of up to 18hrs and the ability to jump steps in the auto mode. I have brewed on it a number of times now and have found a problem with the initial design of the top filter plate which i have fixed.
here a a few pics








I have also created a ZIP file with a few PDF's on the build and also the HEX file for the PIC and the picbasic code for it

wow! When I first clicked on this thread and quickly scanned through the pics, I honestly thought it was a braumeister that you modded. good job on replicating it!!

Where do you get that bendable heating element?

here in OZ i got it from a place called thermal electric elements, I did a quick search and found thishttp://www.omega.com/toc_asp/subsect...subsection=e01 place in the US that sells them. I was fairly difficult to bend the tight radius bends and if i did it again i would ask the factory to do it, after all when I'm paying $130 for a 316 stainless steel element I'm sure they could bend it for me with not too much extra charge

cheers

Nice! How do you seal the bottom when mashing?

as can be seen in the top photo the small pot holds the grain, it has the bottom cut out of it and i used 3/8 heavy duty silicon hose for the seal on the bottom, then there is a bottom filter plate with filter material, then the grain and then a top filter plate with filter material, all held in place by the top bar and wing nut
Ill post pictures when i can

If I were you , start producing more models and look for temporary investors and
disposable income.

hehe as I'm ripping off the braumeister I don't know how well that would go down.
The reason I made all the information available is I want people to go out and make one.
After a few requests here in Australia for the controller I'm working on a Braumiser shield for the Arduino I have already made a prototype board and I'm working on a program for it, being arduino based it will be open sourced, I am planning on getting 10 PCB's made up for here in Australia.

Looks like a nice solution!

I have a similar system, but I opted to just pump water on top of the grain bed, instead of under it. Reason why I did it because I had issues finding a heating element that isn't in the way and because I wasn't sure how to get the seal between the bottom and the "mash tun". Works out pretty darn well. I was going to create some kind of controller for alarms and such but currently am just using a auber instruments pid controller.

What do you use as a filter where the wort leaves the internal mash tun?

the bottom filter is made out of polyester sheer material, the same stuff as hop bags are made out of and the top filter is made out of an IKEA splatter guard so its fine stainless steel mesh
