1. Convection Oven

Convection ovens circulate hot air using a fan, producing evenly baked results across every tray. They shorten baking time and ensure consistent color, making them ideal for cookies, pastries, and sponge cakes. A light exhaust hood is typically required to manage heat and vapors.

2. Deck Oven

Deck ovens use radiant heat from stone or metal decks to create artisan-style crusts and texture. They excel in pizza, sourdough, and baguette baking. Due to their strong heat output and possible steam release, proper ventilation is essential.

3. Rack Oven

Rack ovens are designed for volume and consistency. Rotating racks expose every tray evenly to circulating heat, ensuring perfect color and texture in bread and cakes. They generate substantial heat and steam, requiring a full vent system.

4. Rotary Rack Oven

A rotary rack oven rotates entire racks inside the chamber for uniform exposure, ideal for high-volume bread and cake production. Its built-in steam system enhances crust quality but needs strong exhaust ventilation for safety and comfort.

5. Conventional Oven

Conventional ovens use top and bottom heating elements without a fan, relying on radiant and conduction heat. Simple to operate and cost-effective, they suit smaller bakeries or test kitchens. Vent hoods are optional depending on local regulations and load.

6. Combination (Combi) Oven

Combi ovens combine steam and convection, offering precise humidity and temperature control. They’re ideal for bread, croissants, and roasted menu items. Because of their steam generation, an exhaust hood is mandatory in most commercial settings.

7. Microwave + Convection Oven

This hybrid oven offers the speed of microwaves and the crisping power of convection. It’s excellent for quick reheats or small-batch bakes in cafés. Typically no dedicated venting is needed if it’s an electric countertop model.

8. Rotary / Revolving Oven

Revolving ovens feature rotating shelves that ensure even exposure to radiant heat—perfect for bread, sponge cakes, and biscuits in high-volume operations. Their size and power demand make strong ventilation a must.

9. Tunnel Oven

Tunnel ovens move products along a conveyor through zones of controlled heat, achieving mass consistency for biscuits or packaged bread. With powerful burners and continuous output, they integrate built-in exhaust
