Executive summary
- Deck ovens: stone/steel decks, radiant bottom heat; controllable steam; best for artisan loaves and pastry finishes.
- Convection ovens: fan‑forced uniformity; fast preheat/recovery; best for tray bakes, cookies, meringues, patisserie items.
- Steam/Hybrid: humidity on demand; sheen & volume gains; confirm steam delivery consistency and venting control.
- Buy on outcomes: tray format (600×400 vs GN 1/1), heat recovery, uniformity, steam repeatability, and site services (power/gas + ventilation).
Decision tree: Deck vs Convection vs Steam/Hybrid
├─► Artisan loaves / baguettes → DECK (stone/steel + steam)
│ └─ Also daily viennoiserie? → DECK or HYBRID with programmable steam/vent
└─► Tray bakes / cookies / patisserie → CONVECTION
└─ Need sheen/volume? → HYBRID convection with humidity control
How to use: preheat, steam, vent, rotate (clear workflows)
Deck — artisan bread load
WATCH OVEN SPRING (first 6–10 min) → CONTROLLED VENT TO DRY CRUST → ROTATE IF NEEDED → FINAL COLOUR → UNLOAD
- Steam too late → dull crust; too much → blistering or pale tops.
- Vent timing drives crust: earlier vent = drier crust; later vent = glossier finish.
Convection — tray bake loop
- Even spacing beats over‑loading—air needs room to move around pans.
- Use probe/visual targets rather than time alone; log your best settings.
Hybrid/steam — viennoiserie finish
Record your best programmes on a simple “recipe card” by the oven. Consistency beats guesswork during a rush.
Uniform colour & bake evenness (quick proof tests)
Two simple mapping tests
- Sugar test: sprinkle sugar on an empty tray; caramelisation pattern reveals hot/cold zones.
- Pan rotation test: bake identical trays on each shelf; swap positions mid‑bake; compare colour to decide rotation needs.
Field note: Keep a “shelf map” at the oven. Mark the best positions for delicate items.
Specs that matter: trays, recovery, steam, power & footprint
Tray formats
- 600×400 mm — bakery/patisserie standard; efficient packing for loaves and pastry.
- GN 1/1 (530×325 mm) — common in convection/combi; flexible for café/catering.
Heat recovery & uniformity
Ask for measured recovery time after a door opening at your target temperature. Look for airflow design or deck zoning that reduces hot/cold spots.
Steam generation & venting
- Prefer robust, repeatable steam (generator or injection) with straightforward maintenance.
- Reliable, controllable venting lets you dry the bake for crisp crusts and sheen—make it a documented step.
Power & gas
- Electric: precise control; confirm single/three‑phase and breaker size early.
- Gas: can lower per‑unit energy cost in some sites; requires compliant installation and flue/canopy design.
Steam water quality & descaling schedule
Steam quality drives colour and sheen—and protects your investment. Build a simple routine around three ideas: measure, filter, descale.
What to measure
- Hardness (mg/L as CaCO3) and TDS/conductivity (µS/cm) from your local water report or a test kit.
- Visual checks: door glass haze, steam jets weakening, limescale around injectors and valves.
Scheduling guide (adapt to your site)
| Observed water condition | Filter strategy | Descale inspection | Routine action |
|---|---|---|---|
| Soft to moderate (low visible scale) | Carbon/particulate pre‑filter | Monthly | Wipe jets; check flow and gaskets |
| Moderate to hard (scale spots appear) | Carbon + softening cartridge | Every 2 weeks | Descale per manufacturer; replace cartridges on schedule |
| Very hard (rapid scale build‑up) | Dedicated softener or RO (as approved) | Weekly | Plan frequent descale; keep a spare injector/valve kit |
Always follow the oven manufacturer’s instructions for chemicals and procedures, and confirm which water treatments they approve to protect warranty.
Compliance: FSANZ, WHS (plant), ventilation & gas
Food safety expectations (FSANZ)
- Clean before sanitising: remove soil → hot water + detergent → rinse → then sanitise (heat or approved chemicals). Keep records as part of your food‑safety system. See FSANZ guidance and appendix.
- Temperature control: aim to hold potentially hazardous food ≤5 °C or ≥60 °C where possible. If you use time as a control, apply the nationally recognised 2‑hour/4‑hour rule and track time cumulatively.
Machine safety (WHS — “plant”)
Ovens are “plant”. Manage risks via guarding/interlocks, emergency stop, training and inspection/testing. Approved Codes of Practice can be referred to by inspectors. Make sure your pre‑start, isolation and emergency procedures are documented and known.
Ventilation & exhaust
Commercial kitchen exhaust is typically designed to the AS 1668.2 framework by a competent HVAC contractor. Confirm canopy capture, supply air, duct routing and cleaning intervals in your design files. Keep drawings and commissioning reports for council and landlord requirements.
Gas installation (if applicable)
Gas appliances must be installed and certified under AS/NZS 5601 by a licensed gasfitter. File the compliance certificates with your other site documents and log annual safety checks.
Cleaning & sanitising SOP (copy‑ready)
- Prep: stop service; remove food; post wet‑floor signage.
- Isolate: switch off and isolate energy where required; confirm guard/door interlocks.
- Dry removal: scrape and vacuum crumbs and grease.
- Wash: hot water + detergent; avoid wetting electrics; use dedicated brushes.
- Rinse: remove detergent residues.
- Sanitise: heat or approved chemical per label contact time.
- Dry & reassemble: air‑dry, refit parts, check door seals and glass.
- Verification: test steam/vent/lights/E‑stop; record the task.
Pro tip: Standardise a “hygiene kit” for ovens (brush set, scraper, microfibre towels, heat‑proof gloves). Schedule a weekly descale/door‑seal check.
Planning tables: product fit, capacity, siting & services
Table 1 — Oven type vs best product use
| Oven type | Best for | Strengths | Trade‑offs |
|---|---|---|---|
| Deck | Artisan loaves, baguettes, croissant finish | Strong bottom heat; controllable steam; classic crust | Slower preheat; heavier; larger footprint |
| Convection | Tray bakes, cookies, cakes, meringues | Even airflow; fast recovery; flexible trays | Less “stone effect” bottom heat |
| Steam/Hybrid | Viennoiserie, enriched breads | Humidity on demand; sheen and volume gains | Verify steam reliability & maintenance plan |
Table 2 — Trays & capacity (planning ranges)
| Chamber format | Typical trays | Use case | Notes |
|---|---|---|---|
| 600×400 mm | 3–10 per deck (by chamber) | Patisserie, breads | Confirm exact deck size on datasheet |
| GN 1/1 (530×325 mm) | 4–10 per cavity (by model) | Café, catering | Check fan direction & spacing |
Table 3 — Siting & services checklist
| Parameter | Deck | Convection | Steam/Hybrid |
|---|---|---|---|
| Electrical | Often three‑phase for large decks | Single/three‑phase | Single/three‑phase |
| Gas | Some models | Some models | Some models |
| Ventilation | Canopy/exhaust to design | Canopy/exhaust to design | Canopy/exhaust to design |
| Water (steam) | Required if boiler/injection | Not always | Usually |
Always confirm exact capacity, power and clearances on the manufacturer’s datasheet for the model you shortlist.
Running‑costs maths (electric & gas)
Electricity (kWh)
Replace with your bill tariff. You can also sanity‑check with a government running‑cost calculator.
Gas (MJ)
Worked example (illustrative)
- Electric deck: 12 kW; 6 h/day; $0.30/kWh → daily ≈ $21.60 → annual ≈ $7,884
- Gas oven: 60 MJ/h; 6 h/day; $0.035/MJ → daily ≈ $12.60 → annual ≈ $4,599
Real‑world draw depends on load, cycling, ambient and maintenance. Use your own numbers to refine.
Install & commissioning checklist
- Verify power (single/three‑phase) or gas supply; for gas, installation and certification to the national framework.
- Ventilation: have a competent HVAC contractor design canopy capture and supply air to the national framework; coordinate with council or landlord conditions.
- Place for clear access; check door swing paths and rack movement; protect walkways.
- Commission steam/vent functions; record preheat and recovery at your bake temperatures; pin your “recipe cards”.
- Train operators: burns/hot surfaces, PPE, emergency stop, loading tools, cleaning SOP & records.
- Add the oven to electrical inspection/testing, door‑seal checks, steam descale intervals, glass and light checks.
Troubleshooting quick‑reference
| Symptom | Likely cause | What to try |
|---|---|---|
| Pale pastry tops | Late or no venting; weak steam | Use a short early steam burst; vent at minute 6–8; check jets for scale |
| Uneven colour | Hot spots; airflow blocked | Reduce tray crowding; rotate mid‑bake; run a sugar test to map shelves |
| Slow recovery | Door seal leak; insufficient preheat | Replace seals; preheat ≥30 min; minimise door open time |
| Wet bottoms | Excess steam; under‑bake; loaded cold pans | Shorter steam; extend dry phase; warm pans or adjust load size |
| Steam faults | Limescale; low water flow | Descale as scheduled; replace filters; verify water supply |
Case study: stabilising croissant colour & recovery
Context: A CBD patisserie had pale crowns and slow recovery during morning waves.
- Observation: steam applied late; vent step ad‑hoc; door seals worn.
- Intervention: new programme (preheat ≥30 min → short early steam → controlled vent at 6–8 min); seal replacement; recovery logged.
- Outcome: consistent sheen and lamination; faster turnaround; fewer rejects.
FAQs
Which oven is best for artisan bread?
A deck oven with stone or steel decks and controllable steam. Strong bottom heat supports bloom and ear; venting finishes the crust.
Do I need steam for viennoiserie?
Yes. A short early steam then controlled venting improves sheen and separation of layers.
What ventilation or gas rules apply?
Kitchen exhaust is typically designed to the national mechanical ventilation framework, and gas work is certified under the national gas installation standard by a licensed gasfitter.
How should we clean and sanitise?
Follow clean → rinse → sanitise; avoid wetting electrics; verify guard/door interlocks and emergency stop after reassembly; record the task.
Electric or gas?
Electric offers precise control and simpler siting; gas may reduce energy cost in some venues but adds flue/ventilation and certification steps—compare total installed cost and compliance path.
