Agreed... I'm at 5 seconds for 18 grams on the K-10.

 

That sounds awfully quick for that grind time for the Robur... is that what people are getting?

I think the question needs to be moved towards constancy. Are you talking about the Robur E or the Doser? The robur E can vary quite a bit between shots, but if you are using the Doser and distributing, that won't be an issue... Although you will have more waste. The robur is extremely quick, with new burrs you will be just over 2 seconds for 19g, and after a while just over 3. I don't know about the compak... If you go with a robur e, it will be a love hate relationship! It tends to be more consistent 7-8 days out from roast. I have always wondered how many shots we dump from dosing variance compared waste on using a Doser and distributing. Personally, I think a barista should be able to have less of a variance in that 2.5s grind with distributing than the e model. If speed is your main concern (which it shouldn't be alone) then the robur will amaze you!

It's time that, as an industry, we start showing more interest in the K-10 Fresh grinders.  I believe that both Visions on the west coast, and Prima on the east coast, have these grinders in stock ready to ship.

 

I'd give up Robur speed for Compak consistency and grind quality any day of the week.  There is a reason why VST uses Compak and not Robur when evaluating consistency issues with their baskets.

well the question is not about consitency! i been using a robur e for over a year now and always been happy , nearly never had any problem with dosing.really when you start making over 200 shot per hours well speed is really important and if i save 2.5 sec x 200  well this is it is about 5 minute that i save every hours.so my question is not if one grinder is better then the other one !!! but how long take the compak k10 to grind 19 gr.

 

thanks

Just curious as to what espresso machine(s), and how many baristas you have on bar preparing over 200 espresso drinks/hour. As a trainer, this could be useful for some high volume applications...

If it's not a consistency issue, then I think you have your answer... The robur is about twice as fast.

hi phil really at the moment this is juste a speculation it is juste a plan for a location that would be super busy if we decide to go for it.The plan is so far to get a 4 grhead Gb5 semi automatique  with 2 set of grinder . 2 barista on for the rush hours.i been trying lately to work with a barista on the other side of the counter than just build the drink in it work very good so in extreme case we could go to 3 or 4 barista on duty, but dont think it is needed.

every one so far say that i should go with the swift for that kind of volume but i want to stay away from it.

A Swift is slow, hard to maintain and super inconsistent.  The reason I'm voting for the K-10 over the Robur is that with that even with 5 minutes saved every hour by going with a Robur over a K-10, you are most certainly going to be having at least two failed doses on a Robur E.  Those two failed doses are going to add up to more time than 5 minutes.  It's better to have a more consistent grinder than a fast one in EVERY application, within reason of course.  I don't think a 5 second grind time is unreasonable given the consistency of the K-10.

 

You can only effectively have one barista grinding shots and one barista pulling shots/steaming milk, anyway.  A 5 second grind time is not going to slow down your operations.  It's going to take you longer than that to prep and steam your milk anyway, might as well not have to waste coffee with inconsistent doses.

Yeah, looks like Robur is twice as fast... but at least it costs twice as much to make up for it!

 

Oliver, any reason you wouldn't choose a pair of 2 groups instead of one 4 group? Aside from cost, I mean. Your two baristas would have a pair of wands each, and a little more room to maneuver. Also, though espresso machines tend to be very reliable, it might not hurt to have a little built-in redundancy. This also might give you some layout flexibility, allowing perhaps a single decaf or SO grinder to be placed between machines so you wouldn't need 2 pair. Just a thought. I know this wasn't your original question (and that this subject has already been well covered in previous discussions) just throwing out ideas for your planning phase.

 

Oh, and forget the Swift.

that is a great idea Brady thanks the 2 two group sound great. And look link the price of the k10 will win if it can produce a good product as that price.i will try to get my hand one to try see how i feel about it.

 

thanks
