  • Production Rate On a Single Group Machine?

    most cpmmercial single group machines (commercial NOT prosumer) will do 40-60 per hour in regards to water volume, steam, heatup time and element size, eg my rancillio s27, 4 litre boiler, rated 60 per hour, if you can grind, tamp, etc at that rate. Prosumer machines usually have 1.5-2 litre boilers, so not sure what the recovery times on those would be like.

    Thats a very big if...

    Were talking rates which would generate $8-10k (coffee only) in a cafe from a 1 group machine. Very few (if any) operators would be able to manage 40-50 from any 1 group, let alone a domestic machine.

      My comments are general and not directed at this particular make of machine.

      Dont know how some of these ratings are determined, though feel they are pretty irrelevant.  Whether in a commercial or domestic situation, coffee isnt prepared at regular intervals.

      In my own commercial situation we will usually get hammered at a particular hour on a Saturday, and at home, we may want to prepare 6-8 coffees throughout the day, or consecutively for guests.

      I think its more important to know and understand how any machine will behave with these irregularities.

      Anyway if anyone is hell bent on ratings per hour, on a non-commercial HX machine, with or without PID, try pouring off say 100ml of water from the group, steam for 30 seconds, then repeat the process every minute.  I think you may change your view on how many coffees you and your machine can produce in an hour at an acceptable temperature for extractions.

      The machine for sale reminds me of the Andreja, a very nice machine.

      All the best with the sale!

          :-? Your hand and any of my one group machines any day you like Misha.

          BYO grinder, just so youre in your comfort zone.

          Im well over a million shots in and the last time I pushed a machine, it was well over a kilo per hour for 8 hours straight. :

            60 shots an hour from any single group machine is just about mathematically impossible, say nearly 30 secs for the pour, leaves you 30 secs to grind, dose, tamp, lock in, empty portafilter, wipe clean, draw breath & start again.

            I will have $100 with Chris thanks!

            Interesting sounding machine by the way, should go in a flash i imagine.

                Are we assuming that all drinks have a double espresso base?

                A 6 - 8 ounce drink may only require one, so there is always the possibility of making 2 drinks at once.

                  Ive been trying to resist jumping in, but now this thread has split...

                  Galumay, with my grinder back in the default grind one dose ahead config, that would be one less thing to worry about.

                  The original target was 40-50 coffees an hour. Even at 60 that is only 30 double shots into two separate cups. At that rate it seems quite achievable. There would even be time to steam an occasional hot milk for the girlie men that cant take real coffee ;D Especially so considering Chris can keep up a rate of 1kg/hr for 8hr. Assuming 25gm per double shot that would be 80 coffees an hour, or 640 in the day. You only need to be 75% as quick as Chris and only for 12.5% as long.

                    Not something I am ever planning on doing again and at a cost to quality. Think full dosers and mass production strategies. These days Id rather make a few good ones than many decidedly average ones and nope, Ill never do cattle runs for an Aromafest again.

                      I must admit i hadnt considered the potential of singles, I didnt think anyone drank them in Australia!

                      Mind you if you use 25gm of coffee per pour, thats basically a quadruple so you could get 2 doubles out of it if you could actually cram that much coffee in a basket!

                      Takes the nouveau habit of overdosing to new levels though!!

                      Anyway, I think you have exposed my claim of mathematical impossibility as bollocks, so I will resort to stating that i cant imagine why anyone would wish to try and pull 60 coffees per hour on a single group machine.

                        Im with you Galumay,

                        Regardless of what the machine is rated, its simply impossible. With a multi group machine, yes- doable but with a one group in the real world with a variety of requests, forget it. I think the original question was a somewhat unrealistic one :

                        Ill pass on the hundy on me!

                          Dont know about a pumped machine but with the slight extra delay on a Lever just under the 2 minutes with a double base is possible JUST. So work on a max of 40 if your good and 30 is more feasible and realistic for a single operator with reasonable skills to keep up. To do this you are still going to need a 4 or 5L boiler running on full power at a minimum.

                          If you NEED to punch out more than this then with a second on milk while one does shots you MAY get near the theoretical 60 an hour but then the machine will likely fall over on boiler recovery I suspect.

                            The reason I ask is that I sometimes (twice a month at most) I make coffee for a large group of people and for the rest of the time the machine will (ideally) sit in my kitchen. I currently use a very old (and cheap) 2nd hand 2grp boema that does a so so job. I want something that is a bit more portable. It seems a waste to go all out for a machine that will only be used to its potential very rarely.
                            I tried searching for a thread that would point me in the right direction but im a bit SE challenged

                              There are 28g baskets available. I have a whole pile of them sitting here for 58mm portafilters.
