Combi Ovens Made to Banquet

Are you searching for a new Combi Oven for banqueting season?

We have put this guide together to help you understand what a Combi Oven is, the considerations you need to make, and of course, some leading ovens on the market today.

The combination oven is one of the most popular and versatile pieces of equipment in the commercial kitchen used by a range of venues, from takeaways to fine-dining restaurants and banqueting venues!

What is a Combination (or Combi!) Oven?

A Combination Oven (commonly known as a Combi Oven or traditionally a steamer) is a highly advanced piece of catering equipment which cooks food using steam, convection, or a combination of the two.

These impressive machines can often be the largest, and the most expensive bit of equipment in your commercial catering kitchen. The right Combi Oven will complement your existing menu and transform how you and your kitchen brigade work.

So, it is essential that you choose the right Combination Oven that best suits your operational requirements.

Regeneration Cooking Features

Maintaining consistency in every plate of food that you want to serve during a banquet can become stressful!

Having a Combination Oven with a regeneration cooking feature will allow you to prepare meals ahead of time by cooking, then using a blast chiller to rapidly cool the food down. After this, the food can then be plated and stored in a refrigerated room/cabinet.

Shortly before serving, bring all the plates back up to serving temperature using a regeneration or finishing cooking feature on your Combi Oven. You can protect the finished plates from heat loss by using thermal trolley covers which can keep plates warm.

Regeneration programmes are usually already installed on most ovens, all you need to is to adjust the time for the product. Many Combi Oven manufacturers will help you to “engineer” your plates to ensure all foods regenerate at the same time without losing quality!

Finishing Systems for Banqueting

Finishing systems for banqueting combine all the essential accessories that you need for regeneration.

These include a mobile plate rack, thermal cover and a transport trolley to provide a really efficient hot holding solution! Some trolleys allow you to store up to 120 plates for finishing! With most brands, thermal covers help to keep your food hot for up to 20 minutes.

This helps to get plates as close to the servicing location as possible (often the kitchen is quite a distance from the main banquet or events area) without losing heat or food quality.

Remember it is key that you don’t mix your old/new trolleys with your old/new combi ovens!

What you should consider before buying?

You want to choose the right Combi Oven for you, because this will save you time, energy, space, and money! However, purchasing the wrong one could be costly.

Here are five important considerations you should bear in mind when buying a Combination Oven:

1. Why do I need a Combi Oven?

Having a Combi Oven in your kitchen will allow you to cater for more covers, even when you can’t expand your kitchen footprint! They are a great asset to any kitchen; they allow you more flexible cooking, convenience, consolidate your equipment, and save you money within one piece of equipment.

2. What power supply do I have?

Most models will require a three-phase electrical connection. Three phase tends to be the most popular compared to single phase. A few Combi Ovens can work on a 13-amp 3 pin power supply, they are often smaller in size and have limited functionality which may not be right for your menu.

3. Do I need extraction?

Extraction is a legal requirement, meaning you will need a canopy or ventilation system with 600 mm of overhang to go above your oven (current Industry Regulations 2022). Combi’s can produce a lot of steam and heat, so it is important to have sufficient overhead extraction. Some combination ovens have extraction hoods as an optional accessory, but this will be an additional charge! However, they may be more cost-effective than a full-sized extraction hood.

4. What space do I have available?

Combi Ovens can range in size, from as little as compact 1/2 GN trays*, all the way up to huge roll-in models which can hold around 40 1/1 or 20 2/1 full-sized GN pans.

All models, apart from mini Combis, can take full-size bakery trays. Whilst wanting a larger oven for your kitchen means a higher capacity, it might not be best suited to your kitchen! The right size Combi Oven will depend on your menu, the number of covers you need to accommodate and how quickly you need to serve your customers.

* GN trays (Gastronorm) are a European standard size of kitchen trays and containers that are commonly seen around commercial catering operations.

5. What controls will make my life easier?

Controls are usually either manual or can be programmable via intuitive touch screens. We would recommend to any client that comes to us, that the easier the controls, the better!

Modern programmable models have large touchscreen panels which can often be connected to your phone, making your life in the kitchen easier. The other benefit of touch screen Combination Oven models is that menu items can be pre-programmed, so the oven takes care of all the cooking at the touch of a “button”.

This is ideal when staffing numbers are limited, or you are in the process of training chefs.
