🍞 Dough Divider & Rounder Troubleshooting

❌ Problem 1: Inconsistent Dough Weights

Pieces vary by more than ±3g from target weight

✅ Solution:

  1. Check dough temperature - Ideal range is 24-26°C (75-79°F). Too warm = sticky, too cold = stiff
  2. Inspect cutting blades - Sharpen or replace if dull. Dull blades tear dough instead of cutting cleanly
  3. Adjust pressure settings - Follow manufacturer's specs for your dough weight range
  4. Check feeding mechanism - Ensure dough is fed evenly without air pockets
  5. Calibrate the scale - Use a precision scale to verify and recalibrate

❌ Problem 2: Dough Sticks to Machine Surfaces

Dough adheres to hopper, divider pockets, or rounding plates

✅ Solution:

  1. Apply food-grade oil - Lightly coat surfaces with vegetable oil or non-stick spray
  2. Use flour dusting - Light flour dusting on dough surface before dividing
  3. Check surface finish - Polish or re-coat scratched surfaces
  4. Reduce dough hydration - Very wet dough (75%+ hydration) is more prone to sticking
  5. Clean thoroughly - Remove dough residue after each use

❌ Problem 3: Rounding Produces Irregular Shapes

Rolled dough pieces are not perfectly round or have tails

✅ Solution:

  1. Check rounding plate condition - Replace worn or grooved plates
  2. Adjust rounding time - Increase or decrease based on dough type
  3. Verify dough piece temperature - Consistent temperature ensures uniform rounding
  4. Check pressure on rounding plate - Too much pressure flattens dough, too little doesn't round
  5. Clean rounding channels - Dough buildup causes irregular shapes

💡 Prevention Tips:

  • Clean and oil machine after every use
  • Sharpen cutting blades every 3-6 months
  • Calibrate weights monthly
  • Keep dough temperature consistent

🥣 Spiral Dough Mixer Troubleshooting

❌ Problem 1: Unusual Noises During Mixing

Grinding, squealing, or knocking sounds from the mixer

✅ Solution:

  1. Check mounting bolts - Tighten all base and bowl mounting bolts
  2. Inspect gears - Worn gears need replacement. Look for metal shavings in oil
  3. Check bearings - Worn bearings cause high-pitched squealing
  4. Verify lubrication - Follow manufacturer's lubrication schedule
  5. Reduce load - Overloading causes motor strain and noise

❌ Problem 2: Dough Not Developing Properly

Gluten network weak, dough doesn't pass windowpane test

✅ Solution:

  1. Check spiral hook condition - Worn hooks don't develop gluten properly
  2. Verify mixing speed - Use correct speed for dough type (low for heavy, high for light)
  3. Check bowl temperature - Bowl should be cool (18-20°C) to prevent overheating
  4. Adjust mixing time - Under-mixing = weak dough, over-mixing = dough breakdown
  5. Check flour quality - Low protein flour can't develop strong gluten

❌ Problem 3: Motor Overheating or Tripping Breaker

Mixer stops mid-cycle or circuit breaker trips

✅ Solution:

  1. Reduce batch size - Don't exceed rated capacity
  2. Check voltage - Low voltage causes motor strain. Use dedicated circuit
  3. Clean ventilation - Blocked vents cause overheating
  4. Inspect motor brushes - Worn brushes cause electrical issues
  5. Check for mechanical binding - Seized bearings or gears overload motor

💡 Prevention Tips:

  • Never exceed rated capacity
  • Grease gears every 6 months
  • Inspect electrical connections annually
  • Keep motor vents clean

🔥 Rotary Rack Oven Troubleshooting

❌ Problem 1: Uneven Baking - Different Colors on Same Rack

Products on one side darker than the other

✅ Solution:

  1. Check rack rotation - Ensure rack rotates smoothly at correct speed
  2. Inspect heating elements - Replace any elements that aren't glowing evenly
  3. Clean air circulation fans - Dirty fans cause uneven airflow
  4. Check door seal - Leaking seals cause temperature variations
  5. Calibrate thermostat - Use oven thermometer to verify actual temperature

❌ Problem 2: Oven Won't Reach Set Temperature

Temperature stays below set point or takes too long to heat

✅ Solution:

  1. Test heating elements - Use multimeter to check continuity. Replace faulty elements
  2. Check gas supply - For gas ovens, verify pressure and burner operation
  3. Inspect thermostat - Recalibrate or replace if faulty
  4. Check door seal - Heat loss through bad seal prevents reaching temp
  5. Clean exhaust vent - Blocked vent causes heat buildup issues

❌ Problem 3: Excessive Steam or Moisture in Oven

Products soggy or oven interior dripping with condensation

✅ Solution:

  1. Check steam injection - Turn off or reduce steam after first 5-10 minutes
  2. Verify exhaust damper - Open partially to allow moisture escape
  3. Don't overload oven - Too many products release excessive moisture
  4. Preheat thoroughly - Cold oven causes more condensation
  5. Check product temperature - Frozen products release more moisture

💡 Prevention Tips:

  • Calibrate oven temperature monthly
  • Clean heating elements quarterly
  • Replace door seals every 2-3 years
  • Service burner/elements annually

📐 Dough Sheeter Troubleshooting

❌ Problem 1: Dough Thickness Inconsistent

One end thicker than the other or varies along length

✅ Solution:

  1. Check roller alignment - Adjust both sides equally for parallel rollers
  2. Inspect roller surface - Replace worn or grooved rollers
  3. Verify thickness gauge - Calibrate using feeler gauges
  4. Check conveyor belt tension - Uneven tension causes skewed dough
  5. Feed dough straight - Misaligned feeding causes uneven rolling

❌ Problem 2: Dough Tears or Shrinks After Sheeting

Laminated dough tears or shrinks significantly

✅ Solution:

  1. Rest dough between folds - Give gluten time to relax (30 min minimum)
  2. Keep dough cold - Warm butter layer melts and causes shrinkage
  3. Don't reduce too quickly - Gradual thickness reductions prevent tearing
  4. Check flour dusting - Too much flour between layers causes separation
  5. Verify dough hydration - Too dry dough tears more easily

💡 Prevention Tips:

  • Clean rollers after each use
  • Check alignment monthly
  • Keep machine dusted lightly with flour
  • Replace conveyor belt when worn

💧 Proofing Cabinet Troubleshooting

❌ Problem 1: Inconsistent Proofing - Products Rise Unevenly

Some trays over-proof while others under-proof

✅ Solution:

  1. Check temperature distribution - Use multiple thermometers at different levels
  2. Verify humidity levels - Target 75-85% RH. Low humidity causes skin formation
  3. Check fan operation - Ensure air circulates evenly throughout cabinet
  4. Don't overcrowd - Leave space between trays for airflow
  5. Calibrate thermostat and humidistat

❌ Problem 2: Dough Skin Forms on Surface

Dry skin on proofed dough prevents proper oven spring

✅ Solution:

  1. Increase humidity - Raise to 80-85% RH
  2. Check water supply to humidifier - Clean or replace clogged nozzles
  3. Reduce proofing time - Longer exposure = more skin formation
  4. Cover dough lightly - Use plastic wrap if cabinet humidity can't be raised
  5. Check door seal - Leaks cause humidity loss

💡 Prevention Tips:

  • Clean humidifier weekly
  • Calibrate temp/humidity monthly
  • Use distilled water to prevent mineral buildup
  • Check door seals quarterly
