One of the most common questions from bakeries opening or expanding is simple: rotary rack oven or deck oven? Both bake bread, but each shines with different products and a different workflow. The right choice depends on your product range and how many pieces you bake each day.
How do they bake?
In a rotary rack oven, trays are loaded onto a rack trolley that turns slowly inside the oven while hot air circulates around the products. The rotation means every tray gets the same heat.
In a deck oven, products bake directly on a heated stone deck, with heat coming from the stone below and from above. That is what gives bread a thick, crisp crust and true stone-baked character.
Which product suits which oven?
- Rotary rack oven: tin bread, sandwich and burger buns, rolls, pastries and cookies — anything you need in large numbers with a uniform look.
- Deck oven: crusty loaves, rustic bread, baguettes, flatbreads and pizza — products that need to bake from the base and where the crust matters.
Capacity and space
A rotary oven takes a whole rack at once. Our SDF series, for example, holds 10 to 16 trays depending on the model and bakes 200 to 672 loaves an hour at 300 g. Deck ovens work in layers: our CDKF/10 bakes about 40 kg of product an hour on 40x60 cm trays and can be combined with an optional proofing cabinet in the same unit.
Workflow
With a rotary oven, dough is set out on the rack, proofed and rolled straight into the oven, so nobody has to handle the products one by one. With a deck oven, products are loaded onto the stone with a peel or loader. It takes a bit more hands-on work, but that is exactly where the difference in crust and flavour comes from.
Why not both?
Many bakeries run both: high-volume daily products go through the rotary oven, while crusty and speciality breads go on the deck. If your range is broad, this is the most practical way to get the best out of each.
Conclusion
If you need volume and a uniform look, a rotary rack oven is the better fit. If your products are crusty and bake from the base, choose a deck oven. See our rotary rack oven and stone deck oven pages for full specifications.
