Piece weights varying Weights drifting through the shift Dough sticking inside the divider Oily dough pieces or high oil use Dough pieces torn or degassed Divider jamming or overloading Pieces sticking together on the outfeed Dough bridging in the hopper Cleaning taking too long

Piece weights varying

Hits OEE: Quality

Symptoms: Checkweighed dough pieces vary more than usual and the scaling has to be adjusted often.

Dough consistency or temperature changing

Keep the dough temperature and water addition steady from batch to batch.

Piston or measuring chamber worn

Check piston and chamber clearances and replace worn parts as a set.

Hopper level swinging

Keep the hopper level steady so the dough is fed with an even pressure.

Too little divider oil on the chamber

Check the oil supply to the chamber and the pump setting.

Prevention: Piece weights sampled and charted every hour.

Weights drifting through the shift

Hits OEE: Quality

Symptoms: Weights start on target and creep up or down as the shift goes on.

Dough fermenting while it waits in the hopper

Match the batch size to the divider rate so dough does not sit too long.

Machine warming up and the dough softening

Check the dough temperature at the hopper over the shift.

Oil film on the chamber changing

Check the divider oil level and the oil pump output.

Operators adjusting without recording

Record every weight adjustment with the time and reason.

Prevention: Weight trend reviewed at each break.

Dough sticking inside the divider

Hits OEE: Availability

Symptoms: Dough builds up in the chamber, on the knife or in the hopper and the divider stops.

Divider oil low or the wrong type

Use the food grade divider oil the maker specifies and keep the reservoir filled.

Dough too soft or too warm

Check the recipe water and the dough temperature.

Worn surfaces trapping dough

Replace worn chamber parts.

Cleaning missed parts of the head

Follow the cleaning procedure for the head and knife.

Prevention: Divider head cleaned and inspected at the end of each production day.

Oily dough pieces or high oil use

Hits OEE: Quality

Symptoms: Dough pieces show oil on the surface, or the oil reservoir empties faster than usual.

Oil pump set too high

Reduce the oil dose to the lowest setting that stops sticking.

Oil leaking from a line or fitting

Check the oil lines and fittings for leaks.

Oil type too thin

Use the oil grade the maker specifies.

Worn wiper or seals letting oil through

Replace worn seals and wipers.

Prevention: Oil use recorded per shift.

Dough pieces torn or degassed

Hits OEE: Quality

Symptoms: Pieces come out ragged, torn or flat, and the bread shape suffers.

Piston pressure too high for the dough

Lower the piston pressure for soft or delicate doughs.

Knife worn or timing off

Check the knife edge and its timing.

Dough too stiff

Check recipe water and mixing time.

Divider speed too high for the dough

Reduce the strokes per minute for difficult doughs.

Prevention: Piece appearance checked at start-up for each dough type.

Divider jamming or overloading

Hits OEE: Availability

Symptoms: The drive trips or the divider stops mid-stroke.

Dough too stiff

Check the water addition and mixing time, since stiff dough overloads the piston.

Hopper overfilled with dough pressing down

Keep the hopper below its maximum level.

Dried dough build-up in the mechanism

Clean the mechanism and remove hardened dough.

Drive or clutch wear

Have the drive and overload clutch checked.

Prevention: Jams recorded with the dough type.

Pieces sticking together on the outfeed

Hits OEE: Quality

Symptoms: Dough pieces join up or stick to the outfeed belt.

Flour duster not dusting the belt

Check the duster setting and that it is not blocked.

Outfeed belt too slow

Increase the belt speed so pieces are spaced apart.

Dough too soft

Check the dough water and temperature.

Belt surface worn

Replace a worn belt.

Prevention: Outfeed spacing checked at start-up.

Dough bridging in the hopper

Hits OEE: Performance

Symptoms: Dough hangs up in the hopper, the chamber is not filled and light pieces follow.

Hopper level too low to push the dough down

Keep enough dough in the hopper for steady feeding.

Stiff dough not flowing

Check the dough against the recipe.

Hopper walls dry and sticky

Check the hopper oiling where fitted.

Dough added in large lumps

Feed the hopper with evenly sized pieces from the mixer bowl.

Prevention: Light piece rejects recorded and linked to hopper level.

Cleaning taking too long

Hits OEE: Availability

Symptoms: End of day cleaning overruns and the next start is late.

Dough left to harden before cleaning

Clean the divider soon after the last dough.

Parts hard to remove

Use the quick release parts and keep their fixings in good order.

No standard cleaning sequence

Write the sequence with photos and time each step.

Tools and materials not at hand

Keep a cleaning kit at the divider.

Prevention: Cleaning time recorded per day.

Stop the same fault coming back

Recurring dough divider stops usually trace to a cause you cannot see by hand. The partner we recommend is Fabrico: it tracks OEE and downtime live from PLCs, IoT sensors or AI cameras; where cameras are fitted, the video of a stop sits next to its machine data so the cause can be reviewed; and a technician opens the work order from the stop in the same system. Data is hosted in the AWS EU region, and Fabrico and the company behind it hold ISO/IEC 27001, ISO/IEC 20000-1 and ISO 9001.
