Powering Hundreds of Businesses Including:

The MDJ Digit is a quiet, full-size commercial espresso grinder with 75 mm flat steel burrs, two programmable timed doses, and stepless adjustment. Nuova Simonelli positions it for up to approximately 3 kg of coffee per day, making it a practical primary grinder for medium-volume service or a capable secondary grinder in a busier bar.

Product Features

Two Programmable Doses

Program single and double timed doses for repeatable workflow, or use manual grinding when dialing in and purging.

75 mm Flat Steel Burrs

The 75 mm flat steel burrs provide commercial consistency and a useful balance of speed, heat management, and service life.

Quiet Commercial Operation

The MDJ’s sound-dampened design is well suited to restaurants, offices, and cafés where grinder noise affects the customer experience.

Stepless Adjustment

Micrometric stepless adjustment gives baristas the fine control needed to maintain espresso recipes as coffee and conditions change.

Up to 3 kg per Day

Nuova Simonelli positions the MDJ for up to approximately 3 kg of coffee per day, a useful planning ceiling for medium-volume service.

1.6 kg Hopper

The 1.6 kg hopper reduces refill interruptions while preserving a conventional commercial bar workflow.

Brand

Nuova Simonelli

Nuova Simonelli began in 1936 when Orlando Simonelli built his first espresso machine in central Italy. The company has since become a global maker of professional equipment recognized for ergonomic design, temperature control, and café performance.

The Coffeeionado Take

Who's It For:

  • Medium-volume cafés needing a dependable primary espresso grinder.
  • Restaurants, bakeries, and offices that value quieter grinding.
  • Busy bars seeking a capable decaf or secondary grinder.

It's Right For You If:

  • You need a dependable primary espresso grinder for a medium-volume café, restaurant, office, or hospitality bar.
  • You want quiet on-demand grinding, two programmable doses, a large hopper, and stepless adjustment.

Things to Consider:

  • Dosing is time-based rather than grind-by-weight, so dose weight should be checked when grind size or coffee changes.
  • The manufacturer’s up-to-3-kg daily figure is a planning ceiling; sustained rush performance also depends on duty cycle, ventilation, cleaning, and bean density.
  • At roughly 16 kg, this is a permanent commercial counter appliance rather than a portable grinder.

Our Take:

The MDJ Digit’s appeal is balanced workflow: a large hopper, commercial 75 mm burrs, quiet operation, and straightforward timed dosing. It is a sensible choice when repeatability and lower noise matter more than the extreme speed of a larger 85 mm grinder.

What We'd Tell You In Store

How to Choose a Commercial Espresso Machine

How to choose a commercial espresso machine based on real volume numbers, peak hour output, and drink mix — not vague categories.

How to Choose a Commercial Grinder

Your espresso machine gets all the attention. The grinder does all the work. Every variable that determines shot quality — particle size, extraction evenness, dose consistency — starts at the grinder.

How to Design Your Cafe: Build Your Bar for the Rush

Design your café bar for peak volume, not average traffic. Equipment layout, station design, staffing ratios, and tools that remove steps — what actually matters during the rush.

Setting Up Your Commercial Espresso Machine Right

Water pressure, electrical specs, drain slope, filter flushing — what actually goes into a commercial espresso machine setup, and what gets skipped.

Product FAQ

What type and size of burrs does the Nuova Simonelli MDJ Digit On Demand Espresso Grinder use?

The Nuova Simonelli MDJ Digit uses large 75 mm flat hardened steel burrs designed specifically for high‑volume espresso grinding with excellent consistency and speed.

How long do the burrs typically last, and how often should I replace them?

In a commercial espresso setting, the 75 mm burrs generally last around 1,200–1,500 kg of coffee before needing replacement. In practical terms, that can be several years in a lower‑volume bar and 1–2 years in a busy café. You should replace the burrs when you notice slower grinding, increased clumping, or a decline in shot consistency even after proper calibration and cleaning.

Is the MDJ Digit a stepless grinder, and how precise is the grind adjustment?

Yes. The MDJ Digit uses stepless micrometric adjustment, allowing you to make very fine, incremental changes to the grind size. This is ideal for dialing in espresso precisely rather than being limited to preset steps.

Is this grinder suitable for different types of locations, like cafés, restaurants, or offices?

The MDJ Digit is designed primarily as a commercial espresso grinder for cafés, coffee bars, restaurants, and higher‑volume offices. It is built to handle continuous use during busy service while maintaining consistent dosing and grind quality.

Can the Nuova Simonelli MDJ Digit grind for filter coffee or French press as well as espresso?

The MDJ Digit is optimized for espresso grinding. While the stepless adjustment can be moved coarser, its design, burr geometry, and dosing system are focused on espresso service. If you need frequent switching between espresso and filter or batch brew, a dedicated filter grinder is usually a better option.

What dosing options does this grinder offer? Is it timed, manual, or grind‑by‑weight?

The MDJ Digit is an on‑demand, digitally controlled timed‑dosing grinder. It allows you to program multiple timed doses (for single and double shots, for example) and also run manual grinding as needed. It is not a grind‑by‑weight grinder and does not include a built‑in scale.

How fast is the MDJ Digit, and can it keep up during busy service with multiple drinks in a row?

Thanks to its 75 mm burrs and powerful motor, the MDJ Digit grinds espresso doses very quickly—typically a double shot in just a few seconds. It is built to handle sustained high‑volume use in a commercial environment, so it can keep up during rush periods without overheating when used as intended.

Does the Nuova Simonelli MDJ Digit have a cooling fan or features to manage heat buildup?

Yes. The MDJ Digit is equipped with design features to manage heat during heavy use, including an efficient motor and internal ventilation. Many configurations include an active cooling fan that helps maintain consistent burr temperature and reduces the impact of heat on espresso extraction over long service periods.

How does free installation work?

We want to make your purchase as smooth as possible and will pay the installation via rebate on commercial espresso machines. This includes commercial machines with more than 1 group head and 220V.

If the certified installer needed is over 1.5 hours away then we will pay for the installation call (and install up to the value suggested on page minus call fee). Travel will be paid by customer. Inquire if you have any questions about your location.


Please note, any discounts subject to void the paid installation offer.

At Coffeeionado, professional installation is included with qualifying espresso machine purchases. Our goal is to make the process as seamless as possible — from coordinating the technician to getting your machine up and running on day one.

Which Machines Qualify

Free professional installation is included with all espresso machines of 2 groups or more where indicated on the product listing. This policy applies to espresso machines only and does not cover other coffee equipment such as grinders, brewers, or accessories.

If you are unsure whether your machine qualifies, contact us before purchasing and we'll confirm.

What's Included

  • Travel and labor costs for installation within the technician's service area (up to 2 hours of travel)
  • Setup, basic programming, and commissioning of the equipment
  • Scheduling during regular business hours, Monday through Friday
  • Associated taxes and fees related to the installation itself

Installation must be completed within 90 days of delivery of the equipment. The installation benefit lapses after this window and cannot be reinstated.

How Installation Is Arranged

Depending on your purchase, installation is handled one of two ways:

Arranged directly — In many cases, Coffeeionado or the manufacturer will coordinate and pay the technician on your behalf. We will contact you after your order is processed to schedule the visit.

Reimbursement — In some cases, you may be asked to arrange the installation locally using an authorized technician and submit a rebate form for reimbursement. Once approved, the covered amount will be refunded to the original payment method used for your order.

We will confirm which arrangement applies to your purchase at the time of order confirmation. If you have questions before purchasing, contact us and we'll walk you through it.

What's Not Included

The following are outside the scope of the installation policy and remain the customer's responsibility:

  • Travel or callout costs beyond the first 2 hours of the technician's travel time — if your location falls outside the local service area, the overage is the customer's responsibility
  • Water filtration systems and installation materials — including plumbing fittings, tubing, plugs, outlets, and any other ancillary components required to prepare the site
  • Electrical or plumbing work — site preparation must be completed before the technician arrives
  • Training on equipment operation — installation covers commissioning only, not barista or operational training
  • False start or callout fees if the technician arrives and the site is not ready for installation

Important: If a technician arrives and cannot complete the installation because the site is unprepared, you will be responsible for any callout or false start fee charged by the technician. However, your installation benefit remains intact — the visit will be rescheduled at no additional cost to your policy.

Water Filtration Requirement

Water filtration must be installed and operational before or at the time of installation. This is not optional — operating a commercial espresso machine without proper filtration will void the manufacturer's warranty. If filtration is not in place at the time of the technician's visit, installation may need to be rescheduled and the callout fee will be the customer's responsibility.

If you need guidance on water filtration requirements for your machine, contact us before scheduling your installation.

Service Area

Installation coverage is tied to the manufacturer's authorized technician service area, generally within a 1.5-hour radius of the nearest certified technician. If the customer's location falls outside this area, Coffeeionado will make reasonable efforts to arrange a local authorized technician, but travel costs beyond the 2-hour coverage limit remain the customer's responsibility.

Not sure if you're in a service area? Contact us before purchasing and we'll check your location.

What to Expect on Install Day

Getting a commercial espresso machine delivered is one thing. Getting it actually running — plumbed, programmed, and pulling properly — is another. Here's what happens when the technician comes out.

Before the appointment: Site preparation will be confirmed before technicians make it out. Once your machine ships, we'll coordinate scheduling with you and assign a local certified technician. Before they arrive, make sure your space is ready: the machine's permanent location should be determined, your water line and drain access should be in place, and your electrical supply should match the machine's requirements. 

On the day The technician will handle the physical installation of the machine — positioning, water line connection, and drain setup. Once it's plumbed and powered, they'll run through the setup and basic programming: boiler pressure, shot parameters, and confirming that water flows correctly through the group heads and steam wands. Some basic training will be provided, they'll pull test shots to verify the machine is operating within spec.

After Installation

Once your machine is installed, we'll provide referrals for authorized service technicians in your area for ongoing maintenance and repairs. Coffeeionado offers lifetime support on all equipment we sell — we're here long after the install is done.

Governing Terms

This installation policy forms part of your agreement with Coffeeionado and is subject to our Terms of Sale and Terms of Service. In the event of any conflict, the Terms of Service governs.

Can I pick up the machine at your store?

We do not have a showroom or storefront for customer pickups, so orders cannot be picked up directly from us. That said, there is an exception for La Spaziale and La Pavoni products, you can contact us to arrange.

However, if you'd prefer, we can arrange to have your machine shipped to a local freight terminal/location for pickup instead. Let us know your city/state (or ZIP code), and we’d be happy to check the nearest terminal options for you.
