This is where a commercial combi oven steps in.

A commercial combi oven combines two cooking ways in one unit; steam and convection heat, and it is where the name comes from. Either one of these methods or both of them combined can be used for cooking. A commercial combi oven lets you steam, bake, roast, rethermalize, and blanch foods. Because it replaces multiple ovens, it saves time, space, and money in the long term. We prepared a buying guide about the benefits of combi ovens and how they may help you save money and enhance your commercial kitchen productivity.

Steam, Convection And Combination Modes

A commercial combi oven has steaming, hot air- convection- and the combination of the two as cooking methods.  In combination mode, steam and convection together produce flavorful and moist outcomes with minimal shrinking.

  • Steam: Steam is used to keep the food moist and juicy. This method is mainly used for steaming fish, often shrunk in convection ovens, and vegetables, which retain their natural color when steamed.
  • Convection: A commercial combi oven uses hot air circulates throughout the oven chamber in convection mode, creating dry heat that browns food and eliminates moisture. It is ideal for roasting pizza or cookies, baking, mostly bread, and searing meat. 
  • Combination: Combination mode combines steam and convection methods to cook with retaining moisture. This is the feature that distinguishes the combi ovens. It is perfect for braising or stewing meat, vegetables, or other food, producing soft and juicy food with the browning a convection oven can create.

The Advantages Of Owning A Combination Oven

1. Electric vs. Gas Combi Ovens:

  • Commercial Gas Combi Oven Features:
    • Mostly they are more efficient than electric types.
    • The ones with open burners transfer energy and raise temperature directly.
    • Because of the possibility of power outages, it is better to use gas in some rural areas.
    • If you choose gas combi ovens, you need to consider the type of gas and how it is delivered to your site.

You should also keep in mind some gas types still require electric connections to power fans and digital displays.

3. Boiler vs. Boilerless Combi Ovens

A commercial combi oven can be either with a boiler or boilerless system. A boiler produces steam which is pumped into the oven by boiling water in a tank. To count the disadvantages, we can say that because boiler combi ovens use water to create steam and cool the hot water down, water bills will be higher than boilerless types. And hard water conditions may end in higher maintenance costs for this type.  

boilerless combi oven injects water directly onto the heating element and uses its own water and heat system. It is less expensive to buy and maintain and easier to clean, so more preferable. But one disadvantage of boilerless combi ovens is that they can not create as much steam as those with boilers, so the amount of food it produces will not be the same. 

4. Manual vs. Programmable

With the option that lets you program menus by choosing cooking modes and accurate temperature and moisture controls, you can customize foods and easily cook all the recipes just with the touching of a few buttons in programmable units.

It offers nearly more than 200 multi-stage cooking cycles in the memory, including different cooking steps. With these programmable cycles, the staff can quickly cook a variety of food consistently every time and just in a single process.

5. Commercial Combi Oven Sizes

Commercial combi ovens are available in countertop, floor, and double-stacked models. They vary in size, while some can fit 5 pans, bigger versions can handle up to 40 pans. A model that is too large for your kitchen will narrow your space, and if the capacity it has is over your need, you’ll be overspent your money for no reason. Same way, a commercial combi oven that can not meet the requirements won’t be able to handle the needed capacity, decelerating work. Knowing your available space and how much capacity your kitchen requires will make you choose the right one.

Ventless Combi Oven: While vented hoods are commonly used because of the regulations and codes, there are ventless types, allowing you to place them anywhere you want.

Code Scanners: Some ovens have the software to cross the food items with stored cooking instructions and set the controls after reading the product code.
