Operating amachine à scie à os requires precision and safety awareness. This guide breaks down professional techniques to maximize efficiency while preventing accidents or meat contamination.
Étape 1: Préparation de pré-opération
Safety First!
- Wear PPE: Cut-resistant gloves, safety goggles, and apron
- Clear Workspace: Remove debris, blood, or slippery residues
- Blade Inspection: Check for chips/dullness (replace if gaps >0.5MM)
- Material Prep:
- Chill fresh bones to4-7°C for cleaner cuts
- Partially thaw frozen bones to-5°C to prevent blade strain
Étape 2: Machine Setup
- Blade Installation:
- Align teeth direction with cutting motion (→)
- Tension blade untilping sound appears (prevents wobbling)
- Adjust Cutting Guide:
- Set thickness (4-200MM) using calibration knob
- Test on scrap bone for accuracy
- Secure Workpiece:
- Use clamps/vise grips for irregular bones
- Never hold meat by hand within15cm of blade
Étape 3: Cutting Techniques
| Bone Type | Blade Speed | Feed Pressure | Pro Tip |
|---|---|---|---|
| Beef/Lamb | Medium (800 rpm) | Firm, steady push | Cut perpendicular to grain |
| Poultry | High (1,100 rpm) | Light feather touch | Support fragile joints with mesh net |
| Frozen | Low (600 rpm) | Let blade do the work | Spray food-grade lubricant to reduce friction |
Critical Rules:
➔NEVER force meat through – causes kickback
➔ Maintain3-second intervals between cuts to prevent overheating
➔ Curved bones? Rotate workpiecetoward blade (not against)
Étape 4: Post-Cutting Protocol
- Shut Down Sequence:
- Turn off power → Wait for full stop → Unplug
- Cleaning (Do Within 10 Mins):
- Brush blade teeth with stiff nylon brush
- Flush residue using82°C water + food-safe degreaser
- Sanitize surfaces with 70% ethanol spray
- Blade Storage:
- Hang vertically in dry cabinet
- Coat teeth with mineral oil to prevent rust
Top 3 Mistakes to Avoid
- Skipping Daily Calibration:
Result: Uneven cuts → 15-20% meat waste
Fix: Check guide alignment with feeler gauge each morning - Ignoring Vibration Signs:
Result: Blade fracture → dangerous shrapnel
Fix: Tighten mounting bolts if vibration exceeds 0.5mm amplitude - Wrong Blade for Bone Density:
Result: Torn meat or motor burnout
Fix:- 8 TPI blades for thick beef bones
- 14 TPI blades for poultry/fish
Why Proper Technique Matters
Correctmachine à scie à os operation:
✅ Reduces meat loss by up to 30%
✅ Extends blade life by 6-12 mois
✅ Prevents bacterial growth in bone dust
