📊 Technical Specifications — Ditting KR 1403

🧩 Versions (KR vs KFA vs Lab)

Ditting uses the same grinder platform with different front-end workflows. Here’s the practical difference for buyers:

KR 1403 (Shop / Retail Grinder) — the one you want for bag grinding

📦👊🌀

• Built for retail bag grinding and high throughput
• Includes the bag clamping lever, manual knocker (low retention), and shaker plate (clean, fast bag filling)
• Best fit for roasteries + busy coffee shops selling pre-ground coffee

KFA / KF 1403 (often used for portion/cup grinding)

☕⚖️

• Typically configured for portioning into a grounds cup rather than clamping bags
• May lack the full KR bag-filling workflow hardware (depends on exact SKU)

Lab / “EK/Shop-lab style” workflows

🔬

• More focused on analysis or controlled grinding workflows
• Not optimized for quick bag filling during peak hours

WB.coffee guidance: If your main use case is grinding coffee into retail bags, choose KR 1403. If you mainly grind single doses into a cup for internal use, a KFA-style configuration can be enough.

✅ Installation & Setup Checklist (WB.coffee recommended)

A quick checklist to make sure your install is smooth and your team loves using it from day 1.

1) Power requirements

⚡

• The KR 1403 is typically 3-phase (check your exact model plate)
• Confirm your site has the correct voltage / breaker / connector before delivery
• If you’re unsure: send us a photo of your electrical spec plate or meter cabinet—we’ll sanity check it.

2) Counter space & stability

📏

• Leave enough room for:
  • the grinder footprint
  • bag handling in front
  • comfortable access to the adjustment dial
• Place on a stable, level counter (important for smooth bag filling + less mess)

3) Workflow positioning

🧠

• Put it where bag filling makes sense:
  • near retail shelves / packing area
  • close to labels + sealers (if used)
• Keep a brush + bin nearby for clean operation.

4) First calibration / grind range

🎯

• Start mid-range and test:
  • moka
  • filter
  • French press
• Mark a few “house” reference points for staff (e.g., “Moka”, “V60”, “FP”) for consistency.

5) Retention & cleanliness routine

🧼

• Use the manual knocker after each bag to clear the chute
• Daily: brush around chute + wipe surfaces
• Weekly (or more in busy shops): open and clean the grind chamber area as per manual

6) Bag filling quality control

📦✅

• Use the shaker plate to settle grounds evenly
• Avoid overfilling too fast—let the shaker do the work for tidy, professional bags
