Having a weak link (plastic burr holder) is a good thing!!

November 19, 2013
By Kyle Anderson, Chief Engineer
All of our grinders use a powerful DC motor that produces a very high torque (even at “locked rotor” conditions). In every electro-mechanical device, there should be some kind of easily replaceable or automatically resettable “fuse”. In the case of the Encore, Virtuoso, and Preciso we have two of these safety systems.
The first is an automatically resettable thermal “fuse” (PTC) that when triggered, cuts power to the motor down to a few milliamps until the timer switch turns off. At this point it can cool down and automatically reset. The PTC requires a “locked rotor” event to last for about 2.5 seconds before the PTC is triggered. Under most abnormal conditions (i.e. a rock or unroasted coffee bean), the grinder will stall, then the PTC will trigger, and after the obstruction is removed, the grinder is ready to go again.

In certain circumstances, the shock to the grinder may be great enough that the motor doesn’t have time to stall, but rather the ring burr carrier can act as a mechanical “fuse” . This is the second safety system.  This shows up as inconsistent grind and a broken tab on the burr holder. In the past, our main drive gear was the weak link and this was inconvenient to our users, because this was not a user-replaceable part. We have since redesigned our entire gearbox so it never fails. As a result, 100% of the torque produced by the grinder is resisted by the ring burr carrier. The ring burr carrier can easily be replaced by the end user, so the grinder is back in action quickly.  We have over 180,000 units in circulation and we go through a little less than 3000 burr holders per year. This works out to 1.7% of our Encore, Virtuoso, and Preciso grinder owners replacing ONE burr holder per year (98.3% do not). In almost all cases, failure of this part is due to foreign objects (stones, screws, etc) or unroasted coffee beans getting into the grinder.

Now you know why we have a plastic burr holder and why it’s a good thing!

 

 

 

Grind Settings to get you started!

Baratza provides our users with a range of versatile grinders for all brew types, price points, and to suit many locations and situations.

The Baratza grinders operate in two basic burr styles – conical and flat.  The conical burrs are steel which we use in the Encore, Virtuoso and Preciso.  The flat burrs are available in both ceramic or steel and are used in the Vario and Forté grinders.  We have been doing a lot of testing to find the sweet spot or remarkably tasty flavors in coffee with our grinders. Getting started (brewing coffee) is half the battle, so hopefully the settings in the table below will be of assistance.

Refurbs: a Win-Win!

Picture of Pierce

In conjunction with our Repair Program, to support our goal of reducing waste to the landfills, we also have a vigorous Refurbished Grinder Program!

Refurbished grinders can be preowned grinders that are part of our warranty program or  they are grinders which we have loaned out to support coffee community events such as SCAA (Specialty Coffee Association of America) meetings or TED coffee brew bar support ( Baratza at TED ) .   In all cases they have been fixed, cleaned, and updated to the newest parts, but may have minor blemishes and scratches from previous use. The refurbished grinders come with a 1 year warranty.

Currently we are putting new refurbs up on our web site on a daily basis.  We sell out extremely quickly of the lower priced models (Encore and Virtuoso) as people often go for these as their entry point to moving to a burr grinder, from a lower end whirly blade etc.,  As we come close to the holiday season, you might be interested in helping a special friend make such a move to improving their coffee experience, OR you might be ready yourself for a move up to something like our Vario or Vario-W.  Check them online here.

 

New Products – Forté Grinder and Removable Hopper

March 25, 2013

OK, so the word is out! We have new, exciting products to share!! We sent an email to our customers last week giving them the heads up about what is going to be released and they seem so delighted that they are spreading the news ahead of us. Hard to be mad when we’re glad!

We have two new products, the Forté – a commercial grade, dual-function grinder, capable of grinding by weight AND time, plus a new Removable Hopper. Both products will be launched at the SCAA in Boston in April. Here are some of the details. If you are going to SCAA in Boston, be sure to stop by our booth #1136 so you can see these products for yourself!

Forté Grinder:

Many of our café/roaster customers have been using the Vario-W for the past 1-2 years and love it. It has proven itself to be an incredible work horse in the brew bar setting with accurate, durable,and consistent grinding, producing coffees with great flavor. However, we’ve also had requests for something ‘beefier’ and more commercial. Kyle kicked his creative juices into gear and designed an incredible, innovative multi-functioning grinder that is solid. We’re very excited about this new addition to our grinder line-up and feel that it will answer the needs of café, roasters, and coffee geeks. Below is a teaser.


Key Features:

  • A new DC motor with 70% more power than the current Vario and with twice the duty cycle (>50% run time)
  • All metal enclosure
  • All metal grinding chamber
  • New graphic touch-screen user interface
  • Integrated Weight and Time based grinding
  • Auto-dosing feature that converts weight to grind time, automatically, to allow precise direct grinding to portafilter
  • New belt drive system (to handle the additional power)
  • Metal detents for positive feel and setting of grind
  • New bean hopper with 20% greater capacity and bean shutoff feature
  • It will be available for general release in July, 2013 and can be purchased with your choice of burr – Ceramic MSRP $950 or Metal MSRP $970
New Removable Hopper

In the process of talking to café operators about the Forté, it became clear that we needed to offer a hopper that could be removed, while beans were still in it. So that’s what Kyle came up with. It’s incredibly cool and functional!

Key Features:

  • Built-in bean stopper to allow hopper removal with beans in it.
  • Backward compatible to Vario/Vario-W and (with minor modification) to all Baratza conical burr grinders
  • Accepts Baratza hopper extender
  • Dimensions 5.25″ Diameter X 5.25″ high
  • Capacity 300 grams/10 ounces
  • Available July 2013 for MSRP $35
