Rancilio MD40 Commercial Espresso Grinder

The Rancilio MD40 Commercial Espresso Coffee Grinder is the perfect entry level grinder for a small coffee shop or cafe, as well as a nice upgrade for anyone in need of a heavy duty home grinder. Every feature about the Rancilio MD 40 is heavy duty, from its powerful motor, to its hardened burrs set in cast metal mountings, and even its cast aluminum portafilter fork. The 140 Watt motor turns slowly to prevent overheating the beans. The 50 mm hardened steel burrs have precise, front access adjustment for grind fineness. The body is made of die-cast aluminum and stainless steel for durability in high traffic areas. The Rancilio MD40's high-capacity bean hopper holds 17.6 ounces of coffee and the grinder itself is rated for up to 7.7 pounds per hour of grinding production. The Rancilio MD 40 is by design an espresso grinder only because of its front-mounted doser, which is also heavy duty with many metal parts as well. The doser can be adjusted to dispense between 5 and 10 grams of ground coffee per pull of the dosing lever. The MD40 is a semi-automatic grinder.

Semi-Automatic Espresso Grinder

The Rancilio MD40 Commercial Espresso Grinder is known as a semi-automatic grinder. This means that you must press the power button to turn it on, and press it again to turn it off. While this may be considered a drawback to some, this gives the operater precise control over how much coffee is ground, allowing for freshness to be preserved rather than grinding too much coffee and letting it go stale. The grinding switch is sealed to keep ground coffee from fouling up the mechanism.

Espresso Dosing System

The Rancilio MD40 is a doser espresso grinder, meaning that it grinds into a chamber which dispenses the coffee in uniform amounts. Rancilio builds all of its dosers to be extremely durable, with many metal parts where other companies use plastic. The doser mechanism can be adjusted to dispense between 5 and 10 grams of coffee per pull on the lever. Using the MD40 this way works best when the doser chamber is at least half full. Some baristas grind only what is needed for each shot and use the flapping action of the doser to knock out the clumps in the ground coffee, a very useful feature.

High Quality Grinding Burrs

Consistent espresso grinding requires, among many things, well-made grinder burrs. The Rancilio MD40 employs forged steel medium duty flat burrs that resist wear and corrosion. These 50 mm burr plates are precision balanced to press out a consistently fine to extra fine grind every time.

Heavy Duty Motor

The motor on the Rancilio MD40 is a 140-watt direct drive motor that runs quiet and is extremely powerful. Grinding at the espresso fineness setting puts a lot of strain on any grinder, so the MD40 has been built to handle the job with ease. The motor alone weighs around 12 lbs. and spins at 1,725RPM. It has a high-temperature overload switch to prevent possible damage if a stone gets caught in the burrs.

High Capacity Use

For such a compact grinder compared to other commercial models, the Rancilio MD40 handles a surprisingly high amount of work. The blue-tinted bean hopper (to prevent damage from UV rays) holds 17.6 ounces of beans, and the grinder itself is made to produce up to 7.7 pounds per hour of ground espresso, more than enough for a low to medium traffic coffee shop. The bean hopper mounts directly to the body of the MD40, making it difficult to damage accidentally. When removing it to clean the burrs, the bean hopper has a metal slide plate to keep the beans from falling out of the bottom.

Light weight and large privacy screen
Color: Black, Color: Black
The privacy screen is light weight and of great quality. The screen can block sight and also is easy to set up. It screen is sturdy and stable. It is a cheap solution for separating paces in rooms. The privacy screen is of black color and good good in many places. It can be folded when not used and does not take much space for storage.

Over all review
Color: Black
It’s not a bad divider, the instructions are okay but once I figured it out on my own it was easy. The quality is fine I like how it’s made of metal. The only downside is fall for me is the height. I’m 5”4” yet it’s suppose to be 6 feet tall but it seems to be a little shorter than that. If it was taller and the instructions a little more clear it would get 5 stars.
