Is it better to use electromagnetic heating or heating tube heating for all-electric kitchen equipment?

2025/01/15

For those who want to make an all-electric kitchen, I believe they have heard of electromagnetic heating and electric heating tube heating. So which of these two heating methods is better? Let's briefly explain it to you by SHINELONG editor. Advantages of electromagnetic heating: High heating efficiency: Electromagnetic induction heating can directly make the pot body self-heating, reduce energy transmission loss, and greatly improve thermal efficiency. Fast heating speed: Electromagnetic induction heating can heat objects to the set temperature in a short time, which is particularly suitable for occasions that require rapid heating. Accurate temperature control: By adjusting the frequency and power of the electromagnetic field, accurate control of the heating temperature can be achieved. Environmentally friendly and pollution-free: No harmful substances are produced, no pollution to the environment, in line with the concept of green environmental protection. Long service life: The use of water-electric separation heating avoids the generation of scale. At the same time, the electromagnetic heating structure is simple, and the coil itself only generates a magnetic field, which does not cause too much burden on the equipment itself, so it has a fairly long service life. High safety: It has multiple safety protection functions, such as overheating protection, overcurrent protection, water shortage protection, etc., to ensure the safe operation of the equipment. Low energy consumption: The electromagnetic heating technology has a high conversion efficiency, and less electricity can be consumed to produce the same temperature. Disadvantages: High equipment cost: Electromagnetic induction heating equipment requires more electronic components and control systems, so the cost is relatively high. High requirements for equipment: Specific metal materials are required as heating elements, and the structure and material requirements of the equipment are high. Limited scope of application: It may not be suitable for all types of kitchen equipment and cooking methods. Large equipment volume: Since electromagnetic equipment needs to generate a higher power magnetic field, a larger coil is required, and magnetic field interference must be avoided, so the volume of electromagnetic equipment is generally large. Immovable equipment: Since electromagnetic equipment needs to remain stable when working, it is generally made heavy and immovable. Pot restrictions: Iron or ferritic stainless steel must be used for normal heating. Fear of dry burning: Since electromagnetic heating is extremely fast, dry burning will burn the equipment if irregular operation occurs. Requires high quality of kitchenware: Since electromagnetic heating is rapid and the upper temperature limit is high, if the quality of the kitchenware is not high, it is easy to deform. Advantages of heating tube heating: Low equipment cost: The electric heating tube has a simple structure and a relatively low manufacturing cost. Widely used: Electric heating tubes are widely used in various heating equipment, such as electric water heaters, electric ovens, electric irons, etc., and are also suitable for a variety of kitchen equipment. Easy to install: The electric heating tube is small in size and simple in structure, easy to install and maintain. High heating efficiency: The efficiency of heating tube heating is more advantageous than that of gas, but it is slightly slower than electromagnetic heating. Flexible equipment deployment: The heating tube heating is small in size and will not be affected by vibration. Therefore, universal wheels are usually installed to facilitate the movement of the equipment and flexibly deploy it in various places. Not restricted by the material of kitchen utensils: It can be used with all kinds of pots and pans, and the electromagnetic heating equipment will not be affected by the material of the pot. Convenient and low cost for heating tube replacement: The heating tube is easy to replace and the price is cheap. Disadvantages: The heating efficiency is not as good as electromagnetic heating: The electric heating tube is heated by the resistance wire, and the heating efficiency is not as good as the electromagnetic heating of the pot body, but it is much more efficient than gas heating. The temperature control accuracy is not as good as electromagnetic heating: The temperature control accuracy of electric heating tube heating is slightly lower than that of electromagnetic heating, but higher than that of gas heating, which can meet the needs of most chefs. Easy to scale: Electric heating tube heating is easy to scale on the surface, affecting the heating effect and service life, and needs to be descaled regularly. High energy consumption: Electric heating tube heating relies on electricity, and the electricity price is relatively high. Long-term use will cause high energy consumption costs. Safety hazards: If the electric heating tube is used improperly, it may cause safety accidents such as fire. Fear of dry burning: The heating tube has a fast acceleration speed. If it is caused by dry burning due to improper use and operation, it will easily cause the equipment to burn. Service life limit: The electric heating tube has a service life limit due to technical principles. It will gradually increase the resistance and eventually be scrapped as the use time changes. It is generally recommended to replace the heating tube every 3 years. Limited scope of application: It may not be suitable for all types of kitchen equipment and cooking methods. Comprehensive consideration: Generally speaking, all-electric kitchens will have electromagnetic and electric heating equipment at the same time, and the applicable kitchen equipment is also different. It is recommended to choose according to the actual situation. If the kitchen equipment requires efficient, fast and precise heating, and the equipment cost allows, it is recommended to choose electromagnetic heating. It can improve heating efficiency, reduce energy consumption, and has higher safety and environmental protection, and longer service life. If the equipment cost requirements are low and the heating accuracy requirements are not high, you can choose heating tube heating. It is low-cost and widely used, but you need to prevent scaling during use and replace the heating tube regularly. The above is today's sharing of commercial kitchen equipment.
