    Re: New Vibiemme Dual Boiler Machine


    Only having a three digit display is a pretty sad start.

      Re: New Vibiemme Dual Boiler Machine

      At $3.5K its getting very close to the Marzo GS3 Lite. OK its still about $3K cheaper. ;D

      But I am worried about the dual boiler set up on an e61 group head as it was originally designed for head exchangers.

      I personally think heat exchangers most of the time produces a superior espresso compare to a dual boiler, as theres a greater variation in temperature during your shots. Most of the people will tell me thats bad! or is it? As a lot of you will know for coffee extraction, different flavour will come out at different temperatures. While dual boiler is great for capturing a particular character of the bean (say if you want to maximize the fruitiness) its not great at giving you the whole flavour spectrum. Thats why people still use the plunger

      However there are of course advantages to dual boilers, 1st of all it has better steam performance as you can increase the boiler pressure without affecting the brew temp. 2ndly if you are the kind that likes to experiment different origins/blend with different brew temp then the PID control would be a great tool for that.

        hey baconmeister,

        just for the record, my Minore has a HX

        And as far as the variation in temps for DBs, thats what the PID is for on these new suckers, (and a fridge temp controller on the Minore).

        The steam on my Minore, I think isnt as good as some single boiler HXs Ive used.

        Haha, the more I read that post, the more "hang on a tics" I see.

        Got some talking points there though!

          so yeeza - how much weaker would you say your minore is compared to the (unnamed) HX you compare it with? and is your steam boiler pressure set to the max?

          aaron - wanting tonnes of steam and a DB...(under 3k)

            I was comparing it to the VBM DS. That things a beast on the steam. But Im sure you just get used to it. I havent tweaked anything on the steam side of things regarding my machine. Its fine for me, Ive no real need to tweak it. Admittedly I havent even looked into whether Im able to. Anyone tried it?
            Apparently the new "Giotto Premium Plus (and then some more just in case)" has a good head of steam too.

              Yes the new Giotto has got a 1700W element vs the old 1300W, wondering whether I can replace mine with the new element? Hmm.... I had to buy a couple of tips before I get the steam right, as the holes on the original tips are way too large for the steam capacity.

              Roknee, if you want steam performance go with a HX machine with a large boiler preferably larger than 2L or one with a big heating element like the new Giotto Plus. Or go with a dual boiler with adjustable steam tank pressure, set it to 1.4bar or above and youll have the driest steam ever!

                Re: New Vibiemme Dual Boiler Machine

                cheers yeeza - i thought u were talking about the VBM - ppl love its steam capacity -
                im used to fairly high stema pressure - im on a fb80 at work. im kinda wondering how frustrated im going to be on a prosumer?

                bm - i am pretty much set on a dual boiler - i would assume that you could tweak the minoreII steam boiler for more steam performance?

                i know the idea of a HX with a large boiler and element will yield strong steam - but with higher steam pressure, theres brew temp issues (unless you pid i guess) and associated cooling flushes. i wonder how a VBM DS tamed down to ~9 bar compares steam-wise with a minore that has its steam boiler cranked up?

                  All I can say roknee is you gotta see the VBM machines to believe them....

                  As far as steam performance is concerned- No contest! Come and try my calibrated Domobar Super and you may well have cause to reevaluate dual boiler

                    Hey Chris, what steam pressure are you running on the VBM (the one with the PID)?

                      Hi BM- they run a smidge under 2.0 bar 8-)

                        2BAR? Sweetness!!!
                        My Giotto runs between 0.9 - 1.1 BAR. Its like a Pistol compare to your AK47. ;D ;D
                        You must be getting super smooth milk!

                          and chris - at 2 bar - what kind of cooling fluch are you needing b/w:
                          a. successive shots
                          b. 5, 10, 30 min breaks b/w shots?

                          and pardon my ignorance - is there any potential damage running the VBM at 2 bar? does that put a sig amount mopre strain on its systems?

                            No Aaron,

                            Were talking dual (1.4L) boilers here....The steam boiler runs at 2 bar....Given that the brew boiler is not required for steam, Id *think* it runs virtually zero pressure- except during shot when its dictated by grind and opv to 9 bar ;-). The whole concept of the PID is to eliminate the cooling flush by keeping broup temp consistant....

                            Domobar Super Single boiler machines run circa 1.1 bar- but in a much larger boiler (2.7L), there is still plenty of steam

                              oops - forgot that you were talking about the dual boiler pid - i thought you were saying that you were running the vbm ds hx at 2 bar...

                                I thought we were talking about HX as well...
                                Thats why I was wondering how you keep the brew temp in check when the boiler is running at 2BAR.
