Understand The Technology And Principles Behind Commercial Induction Cookers

Understand the technology and principles behind commercial induction cookers

With the increasing demand for low-carbon and electrification, propaganda similar to “Induction cooking ” is safer, cleaner, healthier and better for the earth” began to appear. Switching to electric heating and induction cooking technology can indeed bring huge air quality benefits because some countries or regions in the Americas have already started operations.

According to the National Kitchen and Bath Association, the induction omen has become a trend in kitchen design: induction is the preferred stove, defeating natural gas and traditional electricity.  Nowadays, the technology of commercial induction cooktop has developed into the only technology that can provide a full range of gas cooking benefits and enjoys a reputation.

The in-depth study of this topic by engineers from a professional manufacturer of commercial induction hobs in China has simplified the difficulty of decision-making in commercial kitchens, the catering industry, or restaurants. We also hope to benefit companies that want to use induction hob cookers for distribution or agency.

What is the principle of commercial induction cooking?

At present, the commercial induction cooker on the Chinese market is a redesigned and improved product based on the principle of a household induction range cooker, which solves the problem of insufficient cooking power. The rated power of a single commercial induction cooktop ranges from 3.5KW to 45KW.

Its working principle is still based on the electromagnetic principle. After inputting the power, the circuit board system of the IGBT module will output a high-frequency alternating current.

Alternating current passing through a large electromagnetic coil will generate a high-frequency strong magnetic field. After the magnetic field is in contact with the induction cookware, the rapid movement of the molecules inside the cookware will generate eddy currents and generate resistance to each other, thereby generating heat without an open flame.

Higher peak power means faster cooking or heating. In commercial kitchens such as restaurants, hotels, canteens, catering, cruise ships, food trucks, industries, etc. (especially those that can use 1/3-phase electricity), the induction method is not to pre-cook and serve dishes, but to help these commercial kitchens improve their competitiveness.

Compared with gas stoves, how safe are commercial induction cooktops?

Due to the avoidance of combustion and gas lines, commercial electric induction hobs are inherently safer than gas stoves. The simplest test is to put a piece of paper on the cooktop to boil water without causing a fire.

Because the heating element does not dissipate heat unless it passes through a suitable metal, the area around the stove is always kept cool; moreover, because there is no open flame, accidental burns can be prevented. This is the simplest answer to the safety of countertop commercial induction burners.

From the perspective of a professional design program, the general module functions of 380v commercial induction range cooker include rectifier filter mode, EMC circuit protection module, LC oscillation module, synchronization module, load detection module, power control module, zero-crossing detection module, high voltage protection module Cookware detection module, voltage detection module, surge protection module, low voltage protection module, temperature detection module, reset module, a current detection module, fan drive module, control, and display module, power supply module, etc. Commercial induction catering equipment is fully protected, with safety features and stable and durable properties that gas hobs cannot match.

Are commercial induction cookers more energy efficient than other stoves?

This is an issue related to power consumption and energy efficiency. For commercial induction cooking, 85-95% of the heat generated is used for cooking. In contrast, for gas stoves or electric stoves, only 65-70% of the heat is used for actual cooking.

This makes induction cooking more energy-efficient. Similar to a gas cooker, the power and heat settings can be adjusted immediately on the commercial induction stovetop. When cooking with a commercial induction cooktop, the accelerated cooking speed can save a lot of time.

Power consumption is one of the key characteristics of commercial induction burner cooktops, in KW/hour, it determines important operating parameters of the equipment, such as electricity consumption, heating intensity and speed, and the number of burners.

This function is objectively determined by the electromagnetic principle and is a key node that affects traditional chefs from natural gas to commercial induction cooktops. (No “Char” open flame)

Considering the chef’s dependence on “visual” prompts, induction cooker manufacturers have implemented technological innovations that rely on the intensity of the blue “virtual flame” of the LED display to visualize the heat of the pot. Despite this, the chefs still use gas flames with pride. The concept of gas flame has dominated the minds of these chefs.

Wrapping Up!

In China, the energy-saving technology and energy-efficiency evaluation technology of commercial induction range cookers are quite mature, and the production and sales volume ranks first in the world, of which the catering industry accounts for 70%. The export business of commercial induction range cooker manufacturers is also increasing.

At present, although some countries are working hard to implement “low carbon emission” and “electrification” policies, there is still a long way to go from the most popular kitchen trend to the popularization of real commercial induction cooktops. All commercial induction cooker suppliers are working hard to improve their competitiveness and reputation, so that induction cooking technology can be used more widely.

Let’s look at the power consumption data from India. Taking into account the basic situation data of different fuels and cooking systems, the price of available heat (per rupee) and the comparative cost of cooking are estimated. The following table (Comparative cost of cooking, when the electricity cost is taken Rs.3/kwh):

Another test conducted to support higher induction efficiency shows that commercial induction cooktops (25Kw, 380v 3 Phase) do save electricity due to minimal heat loss. Let’s take a look at the energy-saving report of the induction wok hob from Wanjiang Public Security Bureau of Dongguan City (unit price of electricity: 1 yuan/KW; unit price of gas: 8 yuan/kg).

What are the types of commercial induction cookers?

Think outside the box. Use any web search engine and type in the words “commercial induction hob manufacturer” or “China commercial induction cooker brand” and check what you find (really: try it on google now).

The range of applications for truly “commercial” induction cooktops has become wider. As one manufacturer (Lestov cooker supplier) said: “As technology becomes more affordable and the functions of electronic products continue to evolve, you will see high-power induction cooking machines-for high-volume, rapid-production commercial or Industrial-grade venues.”

Chinese commercial induction hob manufacturers consider almost all cooking methods, such as searing, stir-frying, frying, roasting, baking, boiling, slow simmering, steaming, stewing, braising, etc. These cooking skills can be subdivided or combined through the function of commercial induction kitchen cooking equipment so that chefs can be trained to obtain excellent results in cooking.

Therefore, the general categories of manufacturers are commercial induction cooktop (used for grilling, stir-frying, and frying), commercial induction fry machine (used for frying), commercial induction flattop griddle/barbecue grill (for grilling), commercial pasta boiler/cooker (for boiling), commercial rice steamer (for steaming), commercial stockpot (for boiling, stewing), commercial induction hob (2/4/6/5/3 burners) (use For frying, stewing and simmering).

In order to meet the needs of the size of the kitchen space, you can choose between a movable countertop induction burner, an induction built-in cooktop, and a freestanding induction cooker.

Each category of stove has different rated power options. The mainstream power of commercial induction stovetops on the market is 3.5KW, 5KW, 8KW, and 12KW. There are also high powerful commercial induction stoves (15/18/20/25/30/35/40/45kw) that are used for special purposes, such as large restaurants, factory canteens, catering, industrial applications, etc.

By combining devices with different functions and powers, the advantages of the kitchen can be maximized.

What are the pros and cons of commercial induction cooktops (pros and cons)?

Benefits/advantages:

  • Multiple safety protection with Intelligent control.
  • Stainless steel material is easy to install/use/maintain.
  • Instant adjust to the cooking heat (8 gear power button).  
  • Fast cooking/heating (90%-95% efficiency), short recovery time.
  • Low carbon and friendly environment, low noise, keep the kitchen cool.

The commercial induction stovetop is much higher than the competitor gas stove in terms of energy consumption, efficiency, cooking speed, all-around safety, and ease of use.

All these factors add up to make them an environmentally friendly, money-saving device because they have a very low energy footprint (no waste heat, cool kitchens) and greatly reduce our utility consumption. The commercial induction cooktop is the most competitive and increasingly valued product in future commercial kitchens.

 

Disadvantages of commercial induction cooktop:

(1) Higher initial purchase cost

This is indeed a big disadvantage, although the price has dropped a bit. If you can think that the service life of a high-quality commercial induction cooker can reach more than 8 years, and see the benefits of energy-saving in long-term use, then you may not regret the original decision.

(2) If the power supply is interrupted, the electromagnetic equipment cannot be used.

For areas with underdeveloped or unstable electricity or high electricity bills, this is the most deadly factor affecting commercial induction cooktops. The low-temperature insulation setting is not a necessary program function for all commercial induction cooktops.

High power and large size are some of the reasons that electromagnetic technology has not gained popularity immediately. The low-temperature insulation program is only applicable to small-sized induction equipment with a rated power lower than 8KW.

Among Chinese commercial induction hob manufacturers, the level 1 power of a 3.5KW commercial countertop induction cooker with a single burner is about 1KW, and the level 1 power of a commercial induction cooktop (3.5KW/burner) with 2/4 or 6 burners is 700w or 800w.

The program of these devices is set to intermittent heating, that is, it will stop heating for 3 seconds every 3 seconds of work. The purpose is to ensure that the temperature of the food (in the soup bucket) is around 80 degrees without cooling.

(3) No “Char” open flame

This function is objectively determined by the electromagnetic principle and is a key node that affects traditional chefs from natural gas to commercial induction cooktops. (No “Char” open flame)

Considering the chef’s dependence on “visual” prompts, induction cooker manufacturers have implemented technological innovations that rely on the intensity of the blue “virtual flame” of the LED display to visualize the heat of the pot. Despite this, the chefs still use gas flames with pride. The concept of gas flame has dominated the minds of these chefs.
