Cleveland Convotherm C4 Testimony

Cleveland Convotherm C4 Testimony

To me, being a chef is all about the creation of the food and my menu. I like the creative process, but once I've perfected a recipe, I want my equipment and my staff to recreate that dish, really the entire menu, to my exact specifications each and every time. I want every plate to appear as if it was hand prepared by me. Of course, we have a secret weapon--the Convotherm 4 combi oven. When you have a piece of equipment that cooks everything we throw at it to perfection, it changes the way you operate. Things can get busy in my kitchen, especially when we are preparing hundreds of plates for a conference or banquet. That's when my Convotherm 4 proves why it is the best decision I've ever made. Full loads, mixed loads all cooked to perfection whether we are baking, roasting, steaming, or even grilling. It's like having 4 pieces of equipment in one, only better, because other platforms don't offer the control over the cooking process that Convotherm 4 does. I mean, even something like a full load of croissants bakes perfectly, and they call come out exactly the same no matter which rack they were on. Show me another oven that can do that. In the end, the hardest decision to make was whether to go with the easyTouch or easyDial. Both are easy to use and master. Both cook everything to perfection, but in the end, the sheer control over every aspect of the menu and the creation stage and the ease of use for my staff in the cooking phase made easyTouch the perfect fit for me and my kitchen. They say that Convotherm was designed around me. Well, after using one, I believe it.

Cleveland Convotherm Combi Oven

Cleveland Convotherm Combi Oven

Combi Convection Oven Steamer with simple to operate electronic programmable controls. OES 20.20 Combi Oven Steamer with Chef Peter Schellenbach. This is our largest model, it’s called a 20.20, that means it has 20 pans tall and it’s the 20 width as opposed to the 10 width, the 10 is the narrow; the 20 is the wider. It’s basically two 10 pan combi’s stacked on top of each other so it does have 2 heating elements, 2 fans, things like that. It does have the anti-microbial door handle again where that treatment is embedded in the resin, so scratches and nicks won’t harbor bacteria. It is a two stage door handle. The first stage to there will allow steam energy to vent out safely so that you don’t open it and get hit with a blast of steam. The second stage lifts up; the door opens, and then slides back. All of our full size combi’s have that disappearing door feature, and it’s great from a lot of perspectives. First is, it keeps the aisle way clear in front of the combi so the traffic flow doesn’t have to stop. The second thing is that when the door is all the way open, it isn’t blocking the piece of equipment sitting next to the oven, so the work flow doesn’t have to stop when the oven is being loaded. Most importantly, this large open door isn’t going to drift closed and burn anybody unloading or reloading the oven. This one is showing our standard control panel, we do offer this one and the easy touch across the entire line of combi’s. Assuming that the combi was manufactured after a certain date, the easy touch panel is retro-fittable onto a combi that has the standard control panel if they wanted to upgrade to the more precise control of the easy touch. It can do either racks like this that can hold full sheet trays, it will hold a steam table pan sideways on this rack so I can get 40 steam table pans, 42” steam table pans in this oven, 2 per rack times 20 racks. This cart can be removed and a different cart can go in, the other alternative cart that we have is a plate cassette, it has rings that hold dinner plates. This oven is specifically designed to banquet in a way called plated re-therm in which the food is prepped ahead of time, placed on the plate when it’s cold, and then the entire plate with the food on it is brought back up to serving temperature. This plate rack will hold, the plate rack that fits this oven will hold 96 plates at one time and a typical 96 plate re-therm can be accomplished in less than 15 minutes. Part of the fun of my job actually is that I get to play with these great pieces of equipment all the time. It is so fun to show somebody that they think that they know how it’s going to taste, and bring it out of the combi oven and it’s like watching them taste something for the first time. Because the combi can cook above and below 212 degrees in steam mode, I can do a low temperature steam for things like spinach and the flavor and the mouth feel, everything about that spinach is fantastic when it’s done at that low temperature steam. So it’s just exciting, it’s just fun because everybody gets to taste something out of here and they just can’t believe the quality of the food coming out of it so it’s very gratifying as a chef to be able to serve people food that causes that effect.

Customer questions about this product

My business is at a high elevation; does this change anything when I order gas cooking equipment?
Many gas equipment manufacturers need to make adjustments to the equipment so it operates correctly at elevations over 2,000 feet. Sometimes we can special order from the manufacturer and have your cooking equipment delivered ready-to-go, but in cases where your unit is in stock and waiting to ship, you’ll need to have a qualified service technician come to your location and alter your unit at the time of installation so that it is compatible with a higher elevation. Contact our Special Orders team prior to placing your order, and we will let you know what will work best for the equipment you are planning to purchase.
