Mazzer Philos

InfamousTuba Cafes are running Weber EG1’s so I don’t see why a kafatek wouldn’t be used, also these are in addition to standard hopper grinders (usually mahlkonig e80s now) not instead of hopper grinders. These are in very high end cafes like motors coffee in paris, nostos coffee in London or cafēn in Edinburgh. They usually have a traditional menu and then a rare/frozen menu with coffees costing large amounts of money (upwards of £20 and espresso) so a high end single dose grinder is used

Sure I get that but even in the States where they are more easily available you might find an EG1 in some high end cafes, Kafateks aren’t really used commercially afaik. Even Denis says they’re not suitable for cafes, while EG1s were developed with commercial settings in mind, so that’s probably a big factor too.

Adrianmsmith “NO, they do not.
There’s quite a “misunderstanding” between “ Commercial ” and what Mazzer say…….

Mazzer Philos is a premium light commercial single dose grinder designed to help you get the most out of your coffee. Its elegant and compact design, accurate machining, and sustainable materials make it the ideal choice for demanding baristas looking for quality in small spaces. It is suitable for all extraction methods, from espresso to batch brew.”

Are you suggesting “light commercial” and for “single dose barista grinder” does not in fact mean it is for commercial use? How many times do they mention home?

They even state themselves they wanted to develop a single dose grinder suitable for commercial use in the promo vids 🤣 are you having me on?

The M98V uses servo motor used in CNC machines. Maybe future gen of philos will change design to accommodate multiple sizes of burrs in the same shell space

HarveyMushman What are the benefits/reasons for the induction motors? If other grinders can generate sufficient torque using a DC, why would an induction motor be used instead?

They are relatively cheap and require no rectification circuitry, brushes, or rectification and brushless control circuitry. Just a slip ring commutator and start run cap. So there are lots of upsides. Plus no need for a gearbox, they will just run at 1350 or 1650 rpm.

The downsides are size, which affects formfactor, quite low starting torque, the need for a start/run capacitor which eventually fails (which I suppose balances out brushes in a DC motor (that isn’t brushless). The very low starting torque is an issue, hence why they have to be larger. Speed control is not really possible. Your motor speed is going to be directly rated to mains frequency and number of poles e.g. an American Philos is going to spin faster.

As a result, the Philos is very large for its burr size and as you can imagine would be ridiculous for an 83mm burr. IMO Mazzer could have used a Brushed or brushless DC motor and given the grinder a better form factor (even with a planetary gearbox). If it was in commercial use Brushed which is easy and cheap wouldn’t have been a problem. I changed the brushes in my mums 14 year old washing machine once and as you can imagine they had had a MUCH harder life than any grinder.

So manufacturers often make decision and not always the best ones…take the Kafatec Flat Max 2…I personally think it should not have been variable speed, just fixed 400 RPM (with an appropriate motor). Would have made it much simpler and cheaper.
