Bakery Equipment Repair & Maintenance in the Bay Area
Repair and preventive maintenance for bakery production equipment — ovens, proofers, mixers, dough equipment and the refrigeration that supports them.
Your next step
Keep the next repair decision clear
Diagnostics and repair for bakery ovens, mixers, sheeters and proofers. Tell us which machine is affecting production so we can review the service scope.
Describe the problem
Have the machine type, model, symptom and production access window ready.
Diagnosis & written estimate
Inspection and measurements guide the proposed repair. Review the scope and price before approving work.
Know what happens next
Parts, access and follow-up needs are discussed. Completed work and any remaining limitations are kept distinct.
How KONGRA approaches the diagnostic
A bakery line is a chain: proofing, forming, baking and cooling all affect the same product. When a bake goes wrong, KONGRA looks at the whole chain rather than assuming the oven is at fault.
Oven-side checks include door and hinge alignment, thermostat and thermopile behavior, burner and ignition condition, rack rotation, airflow and steam where fitted, and temperature calibration against measured chamber readings.
Mechanical equipment — mixers, sheeters, rollers and dividers — is checked for drive and belt condition, bearings, guards and interlocks, gearbox and lubrication state, and control response. Somerset dough-processing equipment and Excalibur bagel-divider requests are covered with model verification before parts selection.
Preventive maintenance is where bakeries gain the most: cleaning, calibration, wear items and documented findings before a failure lands in the middle of a production run.
Sveba-Dahlen and Gemini are examples of equipment serviced; naming them implies no affiliation or authorization.

Gas, electrical and refrigerant work is performed only within KONGRA's legal scope or coordinated with properly licensed independent contractors.
Sheeters, rollers and bagel dividers
For dough-processing machinery, the model plate matters as much as the symptom. KONGRA separates equipment identification from general service concerns before recommending parts.
Sheeters and rollers
- Dough sheeter & roller repair — Somerset and other commercial dough-processing equipment, with exact model confirmation before manual matching
Bagel production
- Excalibur bagel dividers — bagel-divider service planning, EAD-100 reference coverage and nameplate verification
Large production ovens
Start with the oven family that matches how the equipment cooks and moves product.
Rack and bakery ovens
- Commercial rack ovens — rotation, steam, airflow, doors and bake consistency
- Sveba-Dahlen rack ovens — C-Series diagnostics and documented C152 service
Other production ovens
- Rational combi ovens — steam, water, fan and control systems
- Commercial oven hub — compare rack, combi, deck, conveyor and rapid-cook equipment
- Preventive maintenance — planned inspection and documented findings
Real equipment, documented diagnostics

During a completed Sveba-Dahlen C152 rack-oven service, two customer-supplied door hinge assemblies were replaced. The door was supported and removed as needed, then reinstalled and aligned; closing and alignment were checked, the oven was reassembled, and a final operational check was performed.

Somerset equipment and model-matched manuals
Electrical configuration and manufacture date are readable, but the model digits are worn. EAD-100 applicability must be confirmed before service documentation or parts are selected.

Frequently asked questions
What bakery equipment does KONGRA service?+
Deck and rack ovens, proofers and retarders, dough sheeters, planetary and spiral mixers, dividers and rounders, and the refrigeration that supports a bakery production line.
Our bakes have become inconsistent — is that a repair?+
Often it is calibration, airflow or door sealing rather than a failed part. Chamber temperature is measured against the set point and against actual product position before anything is replaced.
Do you work around production hours?+
Scheduling is arranged around your production window where possible. Contact KONGRA with your equipment and bake schedule and we will propose the least disruptive slot.
