Commercial Induction Cooking

Automatic Washer - The world's coolest Washing Machines, Dryers and Dishwashers

Induction cooking is made easier to comprehend if you ever paid attention to the percentages of heat that were outlined in range manuals, and the old Frigidaire Range drip trays, for the 5 heat electric surface units.
High is 100%
Medium Hi is 50%
Medium is around 30%
Low is between 20 & 15%
Simmer is around 10% or less.

Most people who go from gas to induction say that it is too hot and burns everything, but they are dealing with incredible speed, using settings that are too high and are not familiar with the percentages of heat except as flame height. With induction, the heat is happening right in the base of the pan. You are not transferring heat from another source to the pan. Several years ago the food section of the NYT did an article about having chefs try an induction unit at home and those were the problems they encountered. You don't pan fry at 80% power. A medium flame would be a 3 or 4 on a 10 power level display and people cannot at first realize that so much cooking can be done below 40% of high heat, but a lot of that is possible because of the extreme efficiency of induction cooking. You are not losing heat to burner grates or coils that are not perfectly flat under the pan because all of the heat is being created in the pan. Another nice feature that I like on one of mine is that after you have set the cooking power for the operation, you can set a timer for how long it is to cook before shutting off; nice if you have something else to do while brown rice simmers. Deep frying is amazing because the oil is hot in a couple of minutes.

Fagor is a large producer of commercial induction cooking equipment and a few years ago reported that sales were very good in commercial kitchens. The virtual elimination of waste heat made management happy because less heat filtered into the building from the kitchen. The kitchen staff was happy with the cooler kitchens and the cooks were happy with the speed and responsiveness of induction.
 
Here in the UK

Every supplier of commercial cooking equipment now has induction units included in the line up both in in cooking suites as shown at the top of the thread and as independent units - both ranges and cooktops (or boiling tops as we in the trade know them) - both built in and portable. They are becoming more and more popular and there are few kitchens which my company supplies that do not have induction units of some kind. About three years ago we supplied the equipment for a cookery school and each and every range supplied (126) had an induction top with fan assisted electric ovens - indeed there were only two gas units (chargrills) supplied in the whole £1.5M project. We are shortly going to supply another, larger school, and again all the units supplied will be induction.

Apart from the ease of installing electric over gas we in the UK have very strict ventilation requirements where any form of gas unit is supplied. Not only do they have to be placed under a mechanically ventilated extraction canopy but there also has to be a mechanically assisted fresh air supply into the kitchen too. These are interlocked too the gas supply so that if either of these fails the whole gas supply is shut down. Its the law!

From a personal point of view I have used an induction top at home since 2006. When I moved house at the end of last year I replaced the gas top with an induction almost immediately. The surprising thing to me was that it was possible to get a 4 zone unit which plugs into a single 13amp outlet - this is the standard domestic outlet here which, for the moment until I get the house re-wired suits my purpose very well. It regulates the load so you cannot have all zones on high together which so far has not been a problem for me, nor do I see it being so in the future. Indeed, had I chose to renew the counter tops (I will probably replace the kitchen in the next couple of years) I probably would just have bought a couple of portable counter top units to bring out when needed - what with microwaves, portable skillets, steamers (I have a built in steam oven), pressure cookers, deep fat fryers, crock pots/slow cookers, rice cookers there hardly seems to be a need for a built in unit any more - I only bought the built in induction top as there was a large hole to fill where the gas top used to be.

Finally, although it might be a tad early for it, on the link is a bit of Christmas fun from Induced Energy - and induction top supplier in the UK

That was cute! Thanks. It made me think of a character in the Sunday Funnies with a steam calliope, Roscoe Sweeney, Buzz Sawyer's sidekick.

Hey, I was right!

Then there was the steam calliope in Show Boat. When you sitting still there's no sense letting good live steam go to waste.

 
I have an induction cooktop that's about 5/6 years old. Cooking with gas is so wasteful IMO. Boils water pretty quickly. All I can say is it's so Jetsons. Samsung induction ranges have blue LED lights that look like a flame..a better visual cue for former gas users...so cool.
 
Not that I'm in the restaurant business anymore, but

I love my Volrath 69500 model (1800 watts/7" max pan footprint), that I found at the thrift for a few bucks. It's an older model, but works great. And as someone mentioned, I'd be surprised if restaurants adopted the induction system in my lifetime, for the main cooking. I know they use these small units, in buffets and other situations. But I like the induction so much, I would love to use it in a kitchen with a mix of older appliances, too.

When they make it

Work with aluminum cookware....then I will consider it, I use Vita Craft , West Bend Flavo Seal and Guardian Service more than any stainless.
 
Volrath

I have a similar Volrath to that one Phil and it is an amazing little piece of hardware. Performance belies the 1800 watt rating since the heat is really being concentrated into the pan. Instant and consistent control raise the bar further.

I understand that for many gas is like comfortable old shoes. But with issues like lack of temperature control, the inefficient thermal coupling into the pan, thermals caused by the waste heat carrying atomized grease about the kitchen etc., I would never accept it into my home.

A commercial kitchen is indeed a different animal. Its a situation where lots of heat is needed constantly and there is a huge hood sucking out hundreds (thousands?) of CFM of air every minute. Gas makes more sense here, it is cheaper per BTU even with all the waste. It will likely be a long time before induction rules the commercial kitchens.

It reminds me a bit of the kids that used to come into the motorcycle shop I worked at. They all wanted to buy the slightly used slick tires off our race bike. The street is a different world, those tires need to get to 200 degrees to work. Even though they said they ride "hard" (nope) slick tires aren't the right choice for the street!
 
Induction Cook-Tops THE FINAL WORD ON SURFACE COOKING

Yes I believe after cooking on an induction CK nearly every day since 1988 induction cooking will finally spell the end of nasty gas cooking in homes and eventually in commercial kitchens. In commercial kitchens [ and home kitchens as well ] one of the main advantages is that it is impossible to start a grease fire on an induction CK due to the safety heat sensors that are under the CT surface.

 

This safety advantage is HUGE in homes as one of the biggest causes of home fires is still things left on a stove top on high heat, and in commercial kitchens once this safety advantage is proven it might reduce the need and cost of fire suppression systems that are required in restaurant kitchens.

 

It is just very hard to start a fire without an open flame or a red hot element that has no heat limitation devices.
 
I just got

a Duxtop 1800W model 9100MC and I love it so far and it was only $75.  Got a Farberware one from Walmart...it worked ok but didn't have as much precision, so I returned it and ordered the Duxtop from Amazon.  I have it sitting on the covers of my Frigidaire gas range and use it unless I'm cooking multiple items.  I'll probably never give up gas completely, but if I ever get to build our dream house, I'll have both in the kitchen.
 
I have a 3000 and a 3500 watt Cook Tek counter top unit. I have not turned a regular surface unit on HIGH since I have had them. The speed and efficiency are overwhelming. Even the 1800 watt Vollrath unit totally spoils you. To put two servings of frozen mixed vegetables in a a covered pan with with a small amount of water and put it on the 3000 or 3500 watt unit and have it boiling HARD in 2 minutes is amazing.

I think back to when we had a gas stove and frozen vegetables came in those blocks inside the waxed white heavy paper carton with the paper over-wrapper showing what was inside. Those blocks took forever to melt and come to a boil over a full flame. I still don't know why my mom did mot at least move the package from the freezer to the refrigerator to give it a head start on thawing, but those frozen blocks thawed faster in a saucepan on our GE's surface units than over a gas flame. The induction is like light years ahead of that.
