Ditting Grinders: Complete 807, 1203, 1403 and 1827 Guide

Ditting specializes in the grinder jobs most home brands never attempt: retail bags, cupping rooms, roasteries, supermarkets, and industrial pre-ground production. Its current professional portfolio contains seven machines, from the 80 mm 807 family to the 240 kg 1827 High Volume system.

This guide separates those seven current grinders from Ditting’s discontinued 804, 805, 903, espresso, and industrial predecessors. It also explains FILTER and LAB SWEET burr choices, shop-grinder workflow, three-phase requirements, burr-life claims, maintenance, FAQs, and the closest grinders sold by Espresso Outlet.

Editorial note: Espresso Outlet does not currently sell new Ditting grinders. Comparisons below match application and capacity, not identical burr geometry or certification. Industrial equipment must be sized with the manufacturer, electrician, dust-control plan, and local service provider.

Current Ditting lineup at a glance

Ditting history

Ditting’s doors opened in Switzerland in 1928. The company built its reputation around precision flat burrs, long-lived shop grinders, and component grinding systems rather than domestic appliances. Ditting says customers still operate machines that are decades old—a useful explanation for why many model numbers remain familiar long after production ends.¹

The brand became part of Hemro Group alongside Mahlkönig, Anfim, and HeyCafé. Within that portfolio, Ditting is the retail, laboratory, bulk, and built-in specialist. Its commercial grinders serve roasters, grocery coffee departments, cupping labs, and businesses selling pre-ground coffee; its component division supplies grinder modules for vending and automatic-machine manufacturers.

This specialization matters. An espresso grinder is optimized to deliver a small timed dose into a portafilter. A Ditting shop grinder must move much larger quantities across a wide grind range, release grounds into a bag or basket, control heat, and minimize retained coffee between customers.

Complete current Ditting professional grinder catalog

Ditting’s official September 2026 featured portfolio contains seven professional grinders. Its “all grinders” archive also displays discontinued models; those are listed separately below.

Ditting 807

The standard 807 is the core modern shop grinder. It uses 80 mm special-steel flat burrs, a 500 W motor, a roughly 510 g hopper, stepless adjustment, bag clamp, knocker, shaker plate, and two active fans. Ditting publishes 7.5 g/s at a medium setting and approximately 3,000 kg median-setting burr life.²

Choose it for retail bags and containers. The shaker helps settle grounds into a bag; the knocker clears the chute. Those details make it more suitable than a hopper espresso grinder for repeated customer orders.

Ditting 807 FILTER

807 FILTER shares the 80 mm special-steel platform and 7.5 g/s published medium output, but replaces the bag-oriented table with an adjustable support for filter baskets. It is intended for cafés that grind larger batch-brew doses directly into a brewer basket. Two fans support repeated use.

The basket support is the deciding feature. A café primarily filling retail bags should use the standard 807 arrangement, while a batch-brew station may be cleaner and faster with FILTER.

Ditting 807 LAB SWEET

807 LAB SWEET changes the grinding heart. It uses 80 mm premium cast-steel burrs, a 700 W motor, a foldable/removable table, and published output of 9 g/s at medium. Ditting lists about 2,500 kg median-setting burr life—lower than the standard special-steel claim, but paired with a distinct sensory and particle-distribution goal.³

LAB SWEET is the most relevant 807 for cupping rooms, sample preparation, recipe development, and enthusiasts specifically seeking the cast-burr presentation. “Sweet” is a burr designation, not a guarantee that every coffee will taste sweeter.

Ditting 1203

1203 is a heavier shop grinder for busy coffee stores, supermarkets, and small roasteries. It is available as KFA, with automatic bag clamp and no bag shaker, or KR, with a manual clamp and bag-shaking unit. The grinder weighs about 38 kg and measures 260 × 640 × 340 mm.⁴

Its value is sustained, straightforward bag grinding. Buyers should specify the clamp version before ordering because KR and KFA change how an operator holds and settles each bag.

Ditting 1403 shop grinder

1403 moves to 140 mm special-steel burrs and requires three-phase power. Ditting publishes 2,200 g/min average capacity, a 1,100 g hopper, a 1,700–2,000 W motor, and approximately 10–15 tons of median-setting burr life. It is offered in KFA and KR versions.⁵

This is not simply a “faster 1203” that can be placed anywhere. The electrical service, bag workflow, noise, heat, production volume, and upstream/downstream handling must justify it. Optional burrs target Turkish-fine or faster coarse production.

Ditting 1403 INDUSTRIAL

1403 INDUSTRIAL adapts the 140 mm system for production. Its 10 kg hopper, industrial-height body, removable spout extension, and 36 g/s published output suit integration into packaging or processing workflows. It is offered with automatic or manual bag-clamp arrangements.

The shop 1403 and industrial 1403 share a burr scale but serve different stations. The industrial model is taller and heavier and assumes bulk bean feed; the standard 1403 is designed around operator-filled retail bags.

Ditting 1827 HIGH VOLUME

1827 is a continuous-operation industrial system. It uses 180 mm burrs, a 5,500 W three-phase motor, 30 kg/70 L hopper, and included 200 L grounds container. The complete machine weighs approximately 240 kg.

The harder burr’s much longer stated life does not automatically make it the right choice. Product, target particle distribution, sanitation requirements, replacement cost, and planned annual tonnage should drive the configuration.⁶

807 vs. 1203 vs. 1403

Closest Ditting alternatives sold by Espresso Outlet

Compak PK100 is the closest stocked comparison for lower-volume multipurpose professional grinding, cupping, and single portions. Its 98 mm burr platform and workflow differ substantially from an 807, so compare collection method, adjustment repeatability, and actual dose sizes.

Compak R120 Eco is the relevant Espresso Outlet option for serious bulk grinding. It belongs closer to the heavy shop/production conversation than an espresso grinder does. Espresso Outlet does not carry a direct equivalent to the 1827’s 300 kg/hour continuous industrial system.

For espresso-only dosing, choose from Espresso Outlet’s commercial espresso grinders rather than buying a Ditting shop grinder merely because its dial reaches fine settings.

Current models versus Ditting’s legacy archive

The following are documented Ditting families but are not in the seven-model featured 2026 professional portfolio:

• 804, 804 LAB FILTER, and 804 LAB SWEET
• 805
• 903
• KE640 ES / VARIO and KE640 2.0 espresso grinders
• 1800 industrial grinder
• Earlier 1203, 1403, KR, KFA, and regional electrical revisions

Ditting explicitly marks 804 LAB FILTER as no longer available while continuing service and parts guidance. A used Ditting can be a strong asset, but its long service life makes exact identification crucial: photograph the rating plate, burr label, adjustment assembly, clamp version, plug, and serial number before purchasing.

Built-in components such as P64, S64, D64 FHA, EMV 80, EMV 64, and EMH 64 are OEM modules for machine manufacturers, not freestanding retail grinders. They belong in a complete brand directory but should not be counted as consumer models.

Installation, cleaning, and burr planning

1. Define the product. Espresso, filter, Turkish, spices, and non-coffee materials may require different burrs or sanitation procedures.
2. Calculate peak throughput. Count the largest bags and shortest rush interval, not only average pounds per day.
3. Confirm power. The 1403 and 1827 require planned three-phase service; never rely on a plug adapter.
4. Control cross-contamination. Purge between flavored, decaf, allergen-adjacent, or distinctly different coffees according to the business’s food-safety plan.
5. Use the knocker or shaker correctly. Chute clearing and bag settling affect retained coffee and fill accuracy.
6. Track burr tonnage. Calendar age is a poor replacement trigger. Record processed weight, output rate, grind quality, motor load, and cup changes.
7. Plan dust collection. Industrial output can create airborne coffee dust and housekeeping burdens requiring professional facility design.

Ditting grinder FAQs

Where is Ditting from?

Ditting is a Swiss grinder brand founded in 1928 and now part of Hemro Group.

How many current Ditting professional grinders are there?

The official featured September 2026 portfolio lists seven: three 807 versions, 1203, 1403, 1403 INDUSTRIAL, and 1827 HIGH VOLUME.

What is the difference between 807 and 807 FILTER?

They share core published burr and output specifications, but 807 is set up for bags while FILTER provides an adjustable basket support for batch-brew workflows.

What makes 807 LAB SWEET different?

It uses premium cast-steel burrs, a 700 W motor, higher stated medium output, and a foldable/removable collection table aimed at lab and sensory work.

What do KR and KFA mean?

They identify bag-handling versions. KR uses a manual bag clamp with shaking unit; KFA uses an automatic clamp and omits the shaker on the cited models.

Does a 1403 need three-phase power?

Yes. Ditting’s current 1403 shop and industrial specifications list three-phase electrical versions.

Can Ditting grinders do espresso?

Some support very fine ranges, and 1827 publishes espresso production figures, but current freestanding shop models are not timed portafilter grinders.

How long do Ditting burrs last?

Claims range from thousands of kilograms on 807 models to hundreds of tons for 1827 hard-metal burrs. Coffee, setting, foreign objects, and maintenance strongly affect actual life.

Is the Ditting 804 still current?

No. It appears in the legacy archive, and Ditting explicitly marks some 804 variants as no longer available.

Is the 1827 suitable for a café?

Usually not. It is a 240 kg continuous industrial system rated up to 300 kg per hour and requires facility-level planning.

Does Espresso Outlet sell Ditting?

No regular Ditting line is currently offered. Compak PK100 and R120 Eco are the closest stocked professional comparisons.

Final perspective

Ditting should be chosen by production job, not by prestige or burr diameter. The 807 family covers specialized café and lab work, 1203 and 1403 handle progressively heavier retail orders, 1403 INDUSTRIAL supports production flow, and 1827 belongs in a true industrial line.
