Event Details:

See RATIONAL Equipment in Action
Buying major commercial kitchen equipment is very different from buying smallwares.
A specification sheet can tell you:
- Capacity
- Dimensions
- Electrical requirements
- Available features
but it cannot completely show you what the equipment is like to operate during actual cooking.
That is what makes a live cooking demonstration valuable.
Instead of only looking at equipment sitting on a showroom floor, visitors will be able to watch the iCombi Pro and iVario being used by a RATIONAL chef.
You can see:
- How the controls work
- How different foods are prepared
- How quickly the equipment responds
- How the cooking process is managed
- How the equipment could fit into a commercial kitchen workflow
What Is the RATIONAL iCombi Pro?
The RATIONAL iCombi Pro is a commercial combi oven that combines convection heat, steam, and intelligent cooking technology in one piece of equipment.
Instead of relying on a conventional oven for one task and a steamer for another, the iCombi Pro is designed to handle a wide range of cooking applications in a single cooking system.
Depending on the menu, an iCombi Pro can be used for applications such as:
- Roasting
- Baking
- Steaming
- Grilling
- Poaching
- Finishing prepared food
This flexibility is one reason combi ovens have become increasingly important in modern commercial kitchens.
Why Are Combi Ovens Popular in Restaurants?
Commercial kitchens often need to produce many different foods using limited space.
A traditional cooking line may require several separate pieces of equipment for:
- Steaming
- Baking
- Roasting
- Reheating
A combi oven combines multiple cooking methods into one footprint.
That can be useful for:
- Restaurants
- Hotels
- Banquet halls
- Catering kitchens
- Schools
- Institutional foodservice
What Can You Cook in an iCombi Pro?
The answer depends heavily on the restaurant concept.
Potential applications include:
- Chicken
- Meat
- Vegetables
- Seafood
- Bread
- Pastries
- Breakfast foods
- Batch-prepared meals
One of the biggest advantages of attending the live demo is being able to see how these cooking methods work instead of simply reading about them.
What Is the RATIONAL iVario?
The RATIONAL iVario is a multifunctional commercial cooking system built around a heated cooking pan.
It can perform tasks traditionally handled by several pieces of kitchen equipment.
Depending on the model and configuration, the iVario can be used for applications such as:
- Boiling
- Pan frying
- Braising
- Deep frying
- Cooking sauces
- Preparing stocks
- Large-batch production
For restaurants producing significant quantities of food, the iVario can be particularly interesting because it combines cooking capacity with precise temperature control.
What Is the Difference Between the iCombi Pro and iVario?
The two systems complement each other but use very different cooking methods.
| RATIONAL iCombi Pro | RATIONAL iVario |
|---|---|
| Combi oven | Multifunctional cooking pan |
| Uses convection and steam | Uses direct contact heat |
| Roasts, bakes and steams | Boils, fries and braises |
| Uses racks and pans inside a cooking chamber | Uses a heated cooking pan |
| Useful for oven-based production | Useful for stovetop-style and batch production |
Together, the systems can cover a wide range of restaurant cooking applications.
Why See the iCombi Pro and iVario Together?
Seeing both systems during the same demonstration makes it easier to understand where each one fits into a kitchen.
For example, a restaurant may use the iCombi Pro for:
- Roasting proteins
- Steaming vegetables
- Baking
- Finishing food
while using the iVario for:
- Rice
- Sauces
- Stocks
- Braises
- Pan-fried items
- Large-batch dishes
Actual equipment needs will depend on your restaurant's menu, volume, utilities, kitchen layout, and production workflow.
Meet RATIONAL Chef Toshit Sharma
The live demonstration will be led by RATIONAL chef Toshit Sharma.
Having a chef demonstrate the equipment gives visitors an opportunity to ask practical questions rather than only discussing technical specifications.
Questions you may want to ask include:
- Which cooking processes work best for my menu?
- What size unit does my restaurant need?
- How would the equipment fit into my existing kitchen?
- Which tasks could potentially be consolidated?
- How does the equipment handle high-volume production?
- What should I know about cleaning and daily operation?
Taste Food Prepared During the Demo
This is not simply an equipment presentation.
Food will be prepared during the demonstration, and guests will have an opportunity to enjoy samples.
That means visitors can see the entire process:
- Food goes into the equipment.
- The chef demonstrates the cooking process.
- Guests see the finished result.
- Guests can taste samples prepared during the demo.
For restaurant operators evaluating commercial cooking equipment, this can provide much more context than looking at a machine that is turned off on a showroom floor.
Who Should Attend the RATIONAL Demo?
The event is open to foodservice professionals who want to learn more about modern commercial cooking equipment.
It may be especially useful for:
- Restaurant owners
- Executive chefs
- Kitchen managers
- Caterers
- Banquet operators
- Hotel foodservice teams
- Institutional kitchens
- Anyone planning a new commercial kitchen
Are You Opening a New Restaurant?
If you are currently designing or building a restaurant, the demonstration can help you understand what newer cooking technology may be able to replace or consolidate.
Equipment decisions made during a restaurant buildout can affect:
- Kitchen layout
- Electrical requirements
- Gas requirements
- Ventilation
- Production capacity
- Labor workflow
Seeing equipment before finalizing a kitchen plan can help operators ask better questions about what they actually need.
Are You Upgrading an Existing Kitchen?
The event can also be useful for established restaurants.
You may be looking to replace equipment because:
- Your kitchen volume has increased
- Existing equipment is aging
- You need more cooking capacity
- You want to consolidate multiple pieces of equipment
- You are adding catering or banquet production
A live demo provides an opportunity to compare a newer system with your current cooking process.
RATIONAL Equipment for Catering and Banquet Operations
Catering and banquet kitchens frequently prepare large quantities of food on tight schedules.
Equipment needs may include:
- High production capacity
- Consistency between batches
- Flexible cooking applications
- Efficient use of kitchen space
Seeing the iCombi Pro and iVario operating together can help catering businesses understand how each system could fit into larger production workflows.
RATIONAL Equipment for Indian Restaurants
Although RATIONAL equipment is used across many cuisines, the systems can also be relevant to Indian restaurant kitchens.
Depending on the menu and production method, restaurants may be preparing:
- Rice
- Vegetables
- Chicken
- Kebabs
- Curries
- Stocks
- Sauces
- Large banquet batches
The live demo gives Indian restaurant operators a chance to discuss their specific menu with the RATIONAL chef and explore where the equipment may fit alongside traditional cooking equipment.
See the Equipment Before You Buy
Major commercial equipment is a significant investment.
Before purchasing, operators should understand:
- Capacity
- Available models
- Utility requirements
- Kitchen footprint
- Production needs
Seeing equipment operating in person can make it easier to determine whether it belongs in your kitchen.
