I think it looks pretty good Kev - A small blue hopper skirt would have been ideal but you do what needs to be done under the circumstances  :thumb:

Lamkin Lane has recently upgraded from Roburs to the new Compak E10 Conics, in the 'Master' configuration - so pretty much the same as mine but with a slightly faster motor.

They've given me some invaluable advice and I've now switched from single-dosing to just filling up the hopper (which is wrapped in aluminium foil to prevent light-spoilage).

I've programmed the #1 dosing option to grind for 1.9s and I've found that every five notches on the grind adjustment ring requires a commensurate change of about .1s to accommodate the change.

Works beautifully. A tap on the on-demand button and I get a 1.9s grind that half-fills the PF and a few taps to collapse the super-fluffy grinds.

Another 1.9s, another tap before tamping and we're good to go.

The grinder seems to throw right for me, and now that I've discovered that it's making a lot less mess.
LONDINIUM I, Compak E10.

Full disclosure: I have commercial arrangements with Bezzera (AU) and Londinium Espresso. I am not required to market them on this forum & any opinions expressed are my own.

A dosing funnel would solve your problems Kelsey!  Pretty good bang for buck given the cost!

The current condition of the AU$ against the US would make buying one from OE a bit pricey ATM.

I had bought an OE dosing funnel to overcome the MMM (Mazzer Mini Mess) only to find it wouldn't fit under the dosing lever when operating.

Although it does fit under the BNZ, my current routine finds it easier dosing into small round glass dish (to check the weight) then using the dosing funnel on the pf, tip the grounds in, one or two taps to settle in the basket, then tamp.

And, like others in this club, and with almost 2 weeks of using the BNZ, I am noticing a substantial quality/taste improvement in the cup.   :P

Hi Kev
I made a chute with some thicker but still easily bendable aluminium
You need to remove the bottom plate and mould it to shape and then refit the bottom plate
When the bottom plate in screwed in it also holds the alloy chute in place

I was going to ask for a pic of your chute after you had mentioned it in an earlier post to me, but forgot.

Can't get much more "homemade" looking than that. What size ball pane hammer did you use?  :rofl:

Seriously though and pardon all the questions, how does hold in place? Is there a lip flanged at the top to hold it between the bottom plate and the main body? Does it cause grind retention at the top of the chute?

I suppose when the bottom plate is removed, it will soon become blindingly obvious (to an ex boilermaker).  ;D

Mazzer Kold Electronic.

One of the primary challenges to busy cafes is maintaining consistency when orders are flowing fast.

Part skill and part equipment, the barista needs to be aware of what is happening to the coffee and in particular the grinder.

These days, we take it as a given that multi-boiler, PID machines remain thermally stable. Worrying about recovery time and shot temps is quite rare unless you are trying to use a 2-group when you should have a 3-group. If you have a quality brand machine and it is setup correctly, with good water filters and clean, then you really don't need to do much except make sure you have the temp correct for the way the coffee is running, e.g. you know the drill, a 1-Deg change can make a difference.

Attention turns to the shot times, dose weights and converted volumes - it's here that the grinder tends to let you down.

We have some pretty busy cafes that push Robur-E's beyond the optimal operating conditions - 3 or 4 kilos an hour causes excessive heat build up resulting in the need to continually set the grind setting a fraction finer throughout the day - only to wind it back at night and start again the next morning.

This is a frustrating exercise and pushes the limits of quality and speed.

We have tried a few alternatives over the last 6 months. The NS Mythios-1 Clima Pro had all the hallmarks of a grinder that would be perfect for cafes - minimal retention, clean + perfect dosing and special treatment of heat build-up. However, the results in the cup where not comparable with the large Compak and Mazzer conicals.

In the last fortnight, we have run a new Mazzer Kold Electronic on the House coffee in a busy cafe. This is a relatively new concept from Mazzer, although it has been a long time coming.

The Kold is not the prettiest looking grinder, but it's built-for-purpose components from the Robur to implement a belt-drive system that is mounted at an offset to create space so the conductive heat from the motor does not rise up and heat the grind-set - a good idea.

Performance-wise, we have found the dose is relatively consistent, e.g. within 0.75g which puts it slightly improved upon the Robur-E it replaced (which was up to 0.9g variance).

The Kold also appears to be slightly better at dosing into the portafilter without excessive waste - why I don't know as it's basically the Robur-E dosing system (perhaps it's just an illusion and we are in fact still in the "honeymoon" phase).

Is it worth the premium over the Robur ? maybe.

It's a question that only a busy cafe can answer - if you struggle to achieve consistency when under the pump, then anything (and everything) you can do to improve is worth it.......so in that context it is a resounding YES.

Great contribution Jeff, thank you.  I thought that Cimbali had a legacy belt-drive conical/plate grinder for exactly that reason.  The Mazzer is obviously in a different class but it begs the question why aren't all the big manufacturers offering this as opposed to the 3 Phase behemoths.

Another reason for putting it in the "hardly 'domestic' bench material" category me thinks.  ::)
Who knows Brett, you're probably close to the money that someone (not having a marital finance manager around) will find a spot for one of these.

A visitor to our house, who is a dear friend and has a somewhat annoying propensity to fiddle with my gear without asking......... on Friday morning thought it was a you-beaut new automatic pod machine and proceeded to place a cup under the grinder's dosing cone............turning around to ask "what button do I press for a larr-taay"......

GOLD!!!

The only better ending to the story would have a button press and a demitasse full of grounds.  When questioned as to 'how do I drink that" the obvious answer is :"look, drinking dry coffee grounds isn't great coffee but it certianly beats Nespresso!'

Yup, know what you're experiencing bcspark. Normally hard to justify a cost step up to a large conical to friends or family.
But the proof/verification is definitely in the cup as far as I'm concerned. The difference in the pour and improved taste going from my Mazzer Mini to the recently acquired (3rd hand) BNZ, is as you said; "amazing".  :coffee2:
Enjoy :exclaim:

I thought I'd reply while I still have my Robur. I got it last Sunday but my wife calls it the monster and wants me to get rid of it forthwith.

In the meantime I've had a play...:)

Surprises include buggerall retention which I didn't expect. There is almost no grind retained. I found out when I went back from plunger to espresso today and really only lost a few grams and not only that, the grind was perfect right off so I wasted a few grams of coffee that was all.

It is big and ugly and not made for the kitchen but it is an amazing machine. Over engineered 100x for home use but that isn't a bad thing.

The grind from it is very light and fluffy, quite different to my Macap M4D and of course no clumps with the doser. I've decided I like having a doser. I really see more good than bad points and it works well.

The grinder is relatively quiet too.

I will enjoy this while I have it.

My kitchen can handle any size grinder
However if you want a good quality grind then you need a large conical grinder

You want to swap for a BNZ as it has the same / similar burr set but is smaller in stature - so it's more kitchen friendly
If you live in Brisbane you can borrow mine to test the waters with your better half

Hi KK,

I live in Perth which I am pleased about but not handy to you!

Yes, Barazi are in Brisbane and they are a great bunch of people who have been very helpful to me over the years.

My BZ40-P was much loved but really it needed a complete strip down and a new boiler probably as well. It was over 20 years old when I sold it. I had it for 12 of those years. I nearly bought another one but I decided I really wanted someone here in Perth for servicing and warranty else I may well have bought another one brand new. If you can buy a new one for $3400 or whatever I'd consider it a better buy than an E61. I love them.

I reluctantly agree that big conicals are just great grinders. Reluctantly in that they are just a tad large and ugly. A company in the UK called Niche are making grinders using 63mm conical burrs which might fill the gap for conicals of quality but for prosumer use at home. An unknown quantity at the moment but look it up.
