Home made pasteuriser

[Alasdair Keddie]

Hi All,

I've decided to experiment with making a medium cider.  After looking at the different ways of achieving this (sucralose / filtering / pasteurisation /keeving) I've opted to try adding sugar and pasteurising.

Has anyone here built a pasteuriser?  In principle it should be fairly straightforward, I would need an immersion heater with a thermostat set to 74C, mounted in a large enough container underneath a false bottom. Something a bit like this:

http://www.shroomery.org/forums/showflat.php/Number/9248822

I've read that some producers fill BiB bags then put the bags in a pastueriser, this is particularly appealing.

Does anyone have any plans or tips for building a home made pasteuriser?

Regards,

Alasdair

The one Lidl offer from time to time seems to do the trick and is not expensive.

Cheers

Then what are you going to do?
As in how are you going to prevent yeast getting back in it?

Shows how I made mine for in bottle pasteurising.

Dave,

 

Do you mean - "how are you going to prevent yeast getting back into the BIB and refermenting the cider, after pasteurisation?"

 

As for our homemade pasteuriser - pump for recirculating, double element, thermostat, timer and display, insulated cattle trough: total £800 - 100 bottles per hour.  

 

Yours

 

Peter

@Peter Ellis: I have heard rumours of the fabled Lidl unit, it sounds ideal but rarely seems to be in stock (no trace of them on Ebay either).  The last reference I can find to it dates back to 2010.

@Dave: Thanks for posting that thread, those units look fantastic!  I've been scouring Google & Ebay trying to find similar stainless steel baths with no luck.  I'd love to know where your brother sourced them?

Regarding letting yeast back in, I'd like to experiment with pasteurising a filled & sealed BiB bag, the only draw back I can see to this would be gas expansion if there is any CO2 present.

@Peter Stuart: Insulated cattle trough sounds interesting, do you have any pics?

Thanks for the feed back so far.

Is there not a risk of it happening? Or is it assumed they will be hot
filled and the risk eliminated.

Another question if I may, in order to do 100 bottles an hour are you
lifting them out one at a time or in crates/cages?

I managed to find some stainless steel kitchen equipment manufacturer. They bulid custom sized shelves, tables whatever are needed in a professional kitchen. I'm sure that there are some in the UK as well. If you draw some sketches, a good company should be able to build it for you. This is certainly not as cheap as a home made version...

FWIW as a trial I pasteurised a 10L BiB of fresh apple juice in my
'famed Lidl' pasteuriser about 6 weeks ago. Two points:

1. You need something to keep the bag upright. I think Vigo sell a stand
but I used the Jigsaw perspex filling plate just resting over the top of
the pasteuriser with the filling hole of the bag poking up through the
slot. That worked fine.

2. Re the sterility issue, I put the tap in just half way so that vapour
and air could escape (also so i could get a thermometer probe in a
couple of times by removing and replacing the tap) but not much else
could get in. Once it was up to temp I did what I would normally do with
bottles - fixed the cap (tap) firmly with the special tool, withdrew the
bag and allowed it to cool on its side so the hot juice could sterilise
the inside of the tap.

So far the juice shows no sign of re-fermentation so on the basis of
this one-off trial I'd not anticipate a problem. I treated it just like
bottle pasteurising but on a bigger scale.

Re the Lidl pasteuriser I bought mine in June 2010 but they didn't seem
to be selling them again in 2011. I think maybe because they described
it as a 'jam maker' which it isn't (inadequate translation from German)
and a number of purchasers felt misled. You can get related 'catering
urns' fairly easily and Vigo will sell you a couple of good if expensive
versions. My Lidl job was only �40 but has developed an earthing fault
now which should be repairable under guarantee. We shall see ;-)

Lidl's only fault that I've ever come across is that because their stuff
is 'limited edition', while they'll happily give you your money back,
they've never got any stock to replace items. A sander I bought from
them had some sort of internal short circuit and expired in a puff of
smoke the first time I used it, 6 weeks after I'd bought it. I got my
money back without the slightest difficulty, but the rest of the stock
had long gone. Fortunately, they had them again 6mths later and all the
matching sanding sheets I'd bought originally could be used. Repairing
isn't really on their agenda. The email addresses in the manual for
service don't appear to be in use, as no-one ever responds.
I'd talk to your local electrician. The things are fairly straightforward.

I concur with the misdescription of 'jam maker'. They'll obviously
sterilise the jars, but anyone contemplating using them for actually
making jam in would be ill advised ! WIs using them for tea urns to
replace their ageing Baby Burcos might be better off !

hi there, i too pastuerised 2 10 litre biboxes. i had excess apple juice and ran out of fermenters last november. i used my burco boiler that i boil my beer wort in. i placed both bags in at a stretch without the taps in at all. checked temp, wobbled the bags to keep them from dropping too far into the water. its a bit fiddly but a darn sight easier than bothering with30 bottles. which i can only fit 13 in at a time. it tastes fine , even now nearly 6 months later. you can get burcos  quite cheaply if you scan around. hope this helps any doubters of trying them, cheers all.

I've pasteurised BiB in a Burco boiler too. I push the taps in one
click and then vent any air part way through and then push in 2 clicks
(that way you can re-use the bags for ordinary cider afterwards). To
get the timings right, I did a test run with a bag of water and
checked the temps before replicating the procedure with juice. I've
done this for 2 years now with fresh juice (about 16 bags in all) and
it keeps a year without any problems.

I don't know how the Lidl "jam maker" exactly looks like, but I guess it should be pretty similar to this one:
