Braumeister NEXTGEN Build

[matho]

well im going to have to replace the pump because im sure it has put a plastic taint in the beer, im going to replace it with a march pump which will just fit and ill be using these QD so i can quickly remove the pump for cleaning and i can use it for my other brewery

Did you try running the pump on only boiling water to see if it is the problem ?
Given the plastics it should be FG and stable up to 100c.

hey Nev i think its coming from the exposed magnet, i pulled the pump apart a few days ago and there was a little bit of water in it and the smell is the same taste im getting from the beer

I have been looking at these and drooling for a while now

i was always going to get some camlocks but then i was waiting for pat (my lhbs owner) to weight out and pack some hops when i saw them, the female QD are $15 dollars and the males are $10 so i thought why not, and they are shiny

Ok thats interesting, I was going to use one of these pumps (Strontium magnet) for my next project.
Did your seller confirm they are certified FG ?

no i didn't get in contact with the seller, i did try and email the manufacture but i haven't heard back from them yet, before use i did run PBW thru it at 65 deg for about 30min, maybe im just being a bit paranoid about it, it is a great little pump that fits perfectly, I'm just a bit worried about it

Cheers Matho, I will get one and run some taste test on it.
I will let you know.

Looking great Steve.

Will have to pop round and have a look at it!

I'm an Italian homebrewer new on the forum and looking around to different "braumeister clone" implementation I have discovered this threadvery interesting and one of the closest to the original one !

If you are interested you can see my rig and ideas on this two threads

Matho I have a couple of question for youjust to understand how you fix a couple of question that are worrying me

The first point is the sealing of the malt pipe with the external vessel bottomI have tested different solutions with silicon tubing an silicone extrusion but I still have some lack of fluidI'm not able to source a proper silicone gasket with right U channel measurements so I'm still trying to find an alternative solution. Any suggestion is appreciated.

The other point is related to the tempertature probe placementI see in some picture you insert it near the pump inlet (and the heating element) outside the malt pipe. In the original assembly it is internal.. near the pump outletany reason for this choice ?

Thank you in advance for support

regards

first of all welcome to AHB Davide,

to seal the malt pipe i have used just 3/8 heavy duyt silicon hose i got from craftbrewer







I cut it down one side and it is slightly larger than needed so that it pushes on itself, I think me leaving the lip on has helped with making the seal

the reason for where i put the temp probe was, i didn't want the wort getting too hot and the hottest point would be near the element and putting it near the pump inlet meant the wort would be flowing past it. One thing i did find was that when the pump rest happened and the heat was on the temp didn't rise because all the heat was going up so when the pump came on the temp would overshoot, so i have fixed the problem by making the pump be on whenever the heat is on and only rest when the heat is off.

your build looks awesome and i hope you fix the seal problem

cheers matho

yeah,.... im busy drawing up design specs for build and theo one stumbling block i have is malt tube sealing.

im almsot thinking metal on metal...... should be good enough?

cheers

 

[matho]

i can't see why 3/8 hose wouldn't work on straight pipe either here is a pic of some 3/8 on a malt pipe i making up if you make it slightly larger than needed then you can make the ends push against each other ( i need to order more hose from craftbrewer)

Thank you matho for the prompt support !!! Pictures are quite clear... There I a basic difference from your malt pipe and mineyou have used a pot with a big hole so the 3/8 silicon hose cut on one side is pressed between two parallel surfaces ad guarantees the sealing.

My malt pipe is just a straight stove pipe so I have a thin (0,7mm) vertical wall that should be sealed on a flat bottom with a very small footprint exactly like the last picture added.

I have tested the silicon hose strategy but with poor resultsindeed I have used a very small hoseIn my idea the more the silicone hose is close to the edge the more is the sealing powerI have also used some food grade silicone glue to fix the hose to the edge

I think the best solution is to find a silicon sealing with a |_| channel instead of a U . I have drown some basic profiles asking some manufacturer to extrude few meaters the point is that the MoQ are not affordable I'm still waiting some answers and quotations but if you have any idea let me know !

The Grain and Grape web site shows replacement seals for the 50lt malt pipe so Speidel must sell them.

Perhaps you could obtain one from them (or an authorised Speidel retailer in Italy) cut it to the length you require and rejoin it with "super glue"

Check here http://www.grainandgrape.com.au/product_in...roducts_id=8879

There also list one for the 20lt unit at $14

Cheers

[matho]

good suggestion wobbly.

Davide the good thing about the 3/8 silicon hose is that it has a wall thickness of 3mm, which with a bit of pressure it compresses to form a seal. I do need to screw down the wing nut a fair bit to make a seal, have you tried more tension on the springs

Hi

I have played a little bit around the sealing issueone point I would like to improve was the system on the top of the malt pipe that press down on it in order to guarantee sealing

I have build a little aluminum cross that has 3 anchorages on the external vessel (the one used for the original cover)

In this way I can easily lock the malt pipe and with the external lever amd proper spring I can apply a good pressure on the malt pipe

The result seems encouragingwith the old silicon seal I was able to see the water level going upI expect that with the new U channel silicon seal I'm waiting everything could work

Moreover I have a short threaded pipe in the middle of the cross where I can screw in the top filter. Easy solution to apply and remove at the end of the mash phase.

Hope next post will be the final one with a video of the complete solution..

Ciao

[kelbygreen]

very nice davide looks like alot of work has gone into that build

 

[matho]

looks good davide I'm sure you will be able to sort it out the seal problem. With a thicker seal and more pressure and you will be right.

On the braumiser side of things I have sorted out a few problems with the way the pump rests works, now it waits ten minutes if the heat is still on it waits until the heat is off and turns the pump off for 2 minutes or until the PID calls for more heat. I had to put this in because the way i had it the pump would rest but the heat was still on, with the temp sensor on the bottom and no circulation the temp sensor would not see any temperature rise until the pump would kick back in and then the temp would overshoot.

I have also added, in auto, the ability to finish stages early by holding in the start button for 1/2 a second and also the ability to pause at any time, it won't be long and ill be able to post all the schematics and program information.

cheers matho
