Commercial kitchen appliances come in many different shapes and sizes. Understanding the differences between them all and what they’re best used for means you can make an informed decision on what is right for your establishment. 

In this post, we’ll look at an advanced piece of equipment that you can use for several different kitchen processes. A combination, combi stove or oven is a powerful appliance that is among the most expensive items you can buy. Buying the right one is therefore all the more important. 

Keep reading to find out the main features of a combination oven, the considerations you should keep in mind, and how this type of oven differs from other similar appliances. But let's start with the question, what is a combi oven? 

What is a Combi Oven?

A combination or combi oven is a type of commercial oven that combines the functionalities of three ovens in one. You can use one to cook using convection (hot air), steam, or a combination of them both. There are also models that combine pressure and steam cooking.

When you convection cook you're using circulating dry heat and it's an excellent way to roast meats and bake bread.

Steam cooking delivers delicately poached fish, steamed rice, or cooked vegetables with the perfect texture.'It can also be used for poaching vegetables.  

Using steam convection together it produces flavorful and moist food with minimal shrinkage.  

Why is it Called a Combi Oven?

A combi stove or oven is called just that because three cooking methods are combined and delivered with one appliance. 

What Does a Combi Oven Do?

A combi stove has three cooking modes, each of which delivers unique food.

The convection heating mode uses hot air that’s forced around the oven cavity with the help of a fan. This creates a dry heat that browns food and removes moisture during the cooking process. Convection heat cooking is ideal for oven frying, baking, and roasting cookies, pizza, French fries, and similar items.  

The steam feature uses steam which creates a moist atmosphere inside the cooking chamber. Water or steam is injected into the cavity of the oven to raise the humidity quickly. Moist cooking keeps food juicy during the cooking process. The steam mode is best for poaching and steaming vegetables and seafood.

When steam and hot air are combined in the cooking process minimal moisture is lost during the process. Choose the combination mode if you’re stewing or braising foods. Veggies and meat will still be juicy and tender after cooking but will be browned much like in convection ovens. If you want a hard crust on bread, combi cooking is perfect. 

What are the Different Types of Combi Ovens?

There are several different types of combi ovens to choose from. Here is a quick description of each to help you decide which is best for your kitchen.

Electric Combi Oven

Electric combi models ovens are powered by electricity. They offer precise temperature control and accurate cooking results. Electric combi ovens are a better option when a gas connection is unavailable or elevation is high.

Boilerless Combi Oven

There is no built-in boiler in boilerless combi ovens. Steam is generated by injecting water directly onto a heating element. Alternatively, a water reservoir is used. Boilerless ovens tend to be smaller than their boiler-based cousins and require less maintenance. 

Applications:

• Where space is limited

• Less maintenance is a requirement

Price: $7,000 - $65,000

Pressure Combi Oven

Pressure combi ovens have the option to operate under high pressure. This reduces cooking timeframes and enhances the flavor. 

These versatile ovens use the functions of a convection oven and pressure cooker to cook food quickly and efficiently. It does it using a combination of hot or warm air circulation and high-pressure steam.

The pressure function increases the internal pressure, raising the boiling point of water, and allowing for faster cookings. The hot air circulation function helps to crisp and brown the food. 

Applications:

• Useful for cooking a wide range of foods including vegetables, soups, meats, stews, and certain baked goods. 

• For cooking dishes where precise and complete control over the temperature and humidity are crucial.

Applications:

• Good choice for smaller kitchens where space is limited

Price: $16,000 - $40,000

What are the Cooking Options in a Combi Oven?

You can use a combi oven for many different cooking methods. Such versatility allows you to accomplish perfection in a range of different dishes. 

Convection Cooking

When used as convection ovens dry heat from the oven’s element is circulated around the food by single or multiple fan function. Such a cooking method delivers efficient and even cooking. 

You can use it for baking bread, pastries, and pizzas, roasting, searing meat at the beginning of the cooking process, and grilling.

Steam Cooking

A combi oven can also be used to generate moist heat for steaming vegetables, fish, and other delicate foods.

Water is injected into the oven and this function is ideal for cooking foods that might otherwise be steamed or boiled individually. 

Combi steamers are particularly effective if you’re cooking fish. Cooking such a delicate ingredient in a conventional oven can be challenging. It’s not a problem with a combi steamer. The moist steam helps prevent shrinkage, drying out, or breaking.

Cooking vegetables using steam rather than boiling water ensures they retain more color and nutritional value.

Combination Cooking

With a combi oven, it’s also possible to have the best of both worlds and can be a massive advantage for high-volume cooking. It’s also the main feature that sets this type of oven apart from many other kitchen appliances. 

Using both dry heat and steam used in combination ensures the right level of moisture for the different foods you’re cooking. 

Combination cooking also allows you to cook at a higher and more humid temperature. This means shorter cooking timeframes and less risk of shrinkage or burnt edges.

It’s an excellent choice for stewing and braising. Meat and vegetables stay juicy and tender but are browned just like they would be if cooked in a conventional oven. If you want a hard crust on your bread, combination cooking delivers the desired results. 

Reheating

Traditionally, reheating food is done using a microwave. However, combi ovens are excellent for reheating food because they deliver even heat and can quickly add rather than remove moisture. Use a combi oven to reheat freezer meals and leftovers to something as good as freshly cooked. 

Whether you're reheating leftovers or bringing chilled food back to serving temperature, the combi oven can help retain the food's quality. Reheating using the steam function preserves moisture, color, nutrients, taste, and texture.

Sous Vide

Believe it or not, you can also sous vide very successfully using a combi oven. Sous vide is a very slow, temperature-controlled cooking method that preserves the original taste, texture, and essential characteristics of certain foods. 

Raw ingredients are vacuum sealed in a plastic bag and can be cooked in a combination oven. Rather than cooking it in a water bath, you can also use a dedicated low-temperature cooking program that some combi ovens have to create the perfect sous vide food.

There is usually a sensor probe that lets you check your combi oven with maximum precision and know precisely when your food is ready and safe. 

Proofing

If you regularly make bread in your kitchen, using your combi oven for proofing will be an important benefit. Many combi ovens have a proofing function, which creates an ideal environment for proofing dough. 

It’s also possible to use a combi oven at low temperatures. A consistent temperature and humidity help the dough rise properly.

Dehydrating

Some combi ovens allow you to reduce the amount of steam and moisture normally used in cooking, thereby reversing the process of moisture introduction. 

Dehydrating foods including fruits, vegetables, and even meat, provides an opportunity to expand your establishment’s menu, add new flavors, and enhance existing dishes. 

Microwave Cooking (in some models)

A microwave function is an option in some combi ovens, allowing you to combine microwave cooking with the other features of the oven. Microwaving speeds up the cooking process and can be more convenient for certain dishes.

Defrosting

The steam mode in a combination stove is great for defrosting frozen foods. Using a low steam temperature is the ideal way to defrost frozen foods quickly.
If possible, use convection steam as this combines dry and wet heat so that the food doesn’t dry out or start to cook as it’s defrosting. 

Grill or Broil

Some combi ovens have a broil or grill feature, however, they tend to be the latest models. Even if a broil or grill feature is not available, convection steam is a super-heated steam that provides similar instant browning results. 

What are the Different Sizes and Capacities of Combination Ovens Out There?

Whatever the size of your kitchen and the volume of dishes you need to cook, there will be an oven that meets your needs. There are three basic sizes and capacities to choose from. 

Countertop Models

If space is at a premium in your kitchen, consider a compact combination oven. It’s been designed to sit on a countertop.

Typically, you can expect countertop models to be smaller in size and have a lower capacity. Such features make a countertop model ideal for smaller kitchens that have a lower capacity. The general capacities for countertop models range from 0.5 cubic feet to cubic feet. 

Half-Size Models
