A combination oven is a versatile cooking appliance that combines the functions of a conventional oven, microwave, and sometimes a steam oven.
It's ideal for busy home cooks who want to cook a variety of dishes with ease.
Combination ovens are designed to cook food faster and more evenly than traditional ovens.
They use a combination of heat, steam, and microwaves to achieve this, making them perfect for cooking a range of dishes from roasted meats to steamed vegetables.
What Is A Combination Oven
A combination oven is a versatile device that can be used for a variety of cooking techniques.
It can poach food, which is a great way to cook delicate ingredients like fish or eggs without drying them out.
Combi ovens can also roast food, bringing out the rich flavors and textures that make a dish truly special.
They're able to steam food, which is perfect for cooking vegetables or seafood to perfection.
Grilling is another option, allowing you to achieve those beautiful sear marks and smoky flavors.
Baking is also possible, making it a great choice for cooking cakes, breads, and pastries.
Combi ovens can even fry food, giving you the crispy exterior and tender interior you crave.
And if you want to cook food to a precise temperature, sous vide is the way to go.
How It Works
A combi oven is a game-changer for any kitchen, and understanding how it works is the key to unlocking its full potential.
Combi ovens use three different modes: convection (dry heat), steam (moist heat), or a combination of the two. This versatility allows you to cook a wide range of dishes with ease.
The core of all combi oven modes is temperature and humidity control. Controlling temperature and humidity is the root of all cook modes.
Relative humidity is the amount of water vapor present in the air, and it plays a crucial role in cooking. Food cooks faster with humidity in the cooking environment, making combi ovens a great choice for many dishes.
Combi ovens can reduce the footprint of your commercial kitchen by replacing multiple pieces of equipment with one. This can be a huge space-saver, especially in smaller kitchens.
The ability to introduce steam to the cooking process increases the relative humidity inside the oven, allowing food to cook at a high heat without drying out or burning up. This makes combi ovens perfect for cooking delicate foods like fish and vegetables.
Combi ovens are easy to program, making it simple to cook customized menu items with the touch of a button. Many modern combi ovens come with advanced features like touch-screen displays and intelligent sensors that monitor the oven's contents.
Fans are used to distribute heat throughout the combi oven, just like a standard convection oven. The oven can then inject water or steam into the oven to raise the humidity, creating a perfect cooking environment.
The combination of heat and steam will seal in flavors and help your dish cook faster. This is especially useful for cooking methods that require a lot of moisture, like steaming vegetables.
Combi ovens can be used for a wide range of cooking tasks, from baking bread and roasting meat to steaming fish and cooking vegetables. They can even be used to keep food warm for extended periods of time, making them a great choice for large events or buffets.

Cooking Methods and Techniques
Combi ovens can cook a variety of dishes using different cooking methods.
Dry heat cooking methods, such as baking, grilling, roasting, and broiling, typically use temperatures set to 300°F or higher to brown food and create flavors.
Baking bread in a combi oven will circulate the temperature and humidity required to produce uniform and flavorful bread.
The convection feature in a combi oven is used to bake bread and roast meat, while the steam function is used to poach fish, steam rice, and cook vegetables.
Combination mode combines hot air and steam to cook food without losing moisture, resulting in tender and flavorful dishes with minimal shrinkage.
Vegetables and meat cooked in combination mode will come out tender with browning, just like a convection oven.
Combis are perfect for cooking breakfast items like bacon, sausage, eggs, and mushrooms at the same time as pastries and croissants.
Combis can also be used for lunch service, cooking meat to tender perfection and baking potatoes and steaming vegetables to perfection.

They can even be used to keep food warm for extended periods of time, making them ideal for a la carte dinner service.
Combis can delicately poach or steam fish and vegetables, preserving their nutrients and fresh taste.
They make consistently cooking desserts a breeze, perfect for dishes like soufflé and crème brûlée.
Characteristics and Benefits
Combi ovens preserve vitamins and nutrients more effectively than conventional cooking methods due to their short cooking times and the presence of steam inside the cooking chamber.
They typically offer multiple modes of operation, including steaming, convection, and superheated steam, with temperature ranges from 30 to 250 °C (86 to 482 °F) or 300 °C (572 °F).
Combi ovens are also great for cooking different dishes in different containers without transferring flavors. This is because the steam-saturated air and hot-air environment are contained within the cooking chamber.
Combi ovens typically contain food racks with dimensions corresponding to Gastronorm specifications (GN racks), which may vary in width and are only suitable for certain sizes of containers.

Some models can hold up to 40 racks, while others may only have 6 or 10 racks. Units with more racks are often free-standing, while those with fewer racks are usually tabletop devices.
Combi ovens offer precise temperatures and moisture levels, thanks to probes that allow for exact temperature and steam settings.
Here are some of the benefits of combi ovens:
- Condense your kitchen by replacing multiple pieces of equipment with a single unit.
- Precise temperatures and moisture levels ensure dishes are cooked exactly as desired.
- Programmable menus simplify complex recipes with a single button press.
- Increase food yield by preserving flavors and nutrients with both steam and convection cooking.
- Energy efficient due to faster cooking times, resulting in lower energy bills.
Technology and Features
Combi steamers generate steam using one of two systems: a boiler or cauldron system that produces steam outside the cooking chamber, or an injection system that generates steam directly inside the cooking chamber.
The injection system spritzes water onto the heating element or a heat exchanger to produce steam. This system allows for more efficient use of space and can be more convenient for some users.
Combi steamers require a water connection or a separate drinking water tank, as well as a water drain. They also need a three-phase alternating current or single phase connection for electrically heated units, or a gas line connection and single phase electrical connection for gas-powered units.
Some combi steamers have analog or digital controls, while others come equipped with PC or USB interfaces, and even touchscreen user interfaces. They may also have a feature to save cooking programs to an electronic cookbook.

Key Features

Combi steamers can be filled and emptied rapidly using rack trolleys, which keep loss of heat through the open door to a minimum. These rolling carts make it easy to transfer entire batches of prepared containers in and out of the combi steamer all at once.
Some combi steamers have a PC or USB interface, which allows for advanced programming and customization. Others have touchscreen user interfaces for easy operation.
To use a combi steamer, you'll need a water connection or a separate drinking water tank, as well as a water drain. This is because the units require a lot of water to generate steam.
Combi steamers can be programmed to perform processes involving several sequential steps, and these programs can be saved to an electronic cookbook. This feature is especially useful for cooks who need to prepare large quantities of food.
The devices also have exhaust-air lines to release steam into the surrounding air, and may give off aromas and grease or oil, depending on the cooking method being used.
Heating Elements
Heating Elements are a crucial part of any heating system, and they come in various types.
Electric resistance heaters are the most common type, converting electrical energy into heat through resistance.
They're often used in space heaters and water heaters due to their simplicity and low cost.
Heat pumps, on the other hand, work by transferring heat from one location to another, rather than generating heat from scratch.
This makes them a more efficient option, especially in mild climates.
Understanding and Choosing
Combi ovens are incredibly versatile devices that can perform a wide range of cooking tasks. They can poach, roast, steam, grill, bake, fry, and even sous vide food.
Choosing the right combi oven for your business is crucial, as it can save you time, space, and money. You should consider what you need it for and what features are essential for your operations.
To get the most out of your combi oven, you need to understand how it works. Combi ovens combine steam and dry heat to cook food quickly and evenly, making them a game-changer for chefs and home cooks alike.
