As a highly modern kitchen tool, the rice cooker (also known as the rice cooker) has a variety of functions such as steaming, boiling, stewing, simmering, and stewing, demonstrating its diverse processing capabilities. However, with the increasing number of rice cooker brands on the market, some low-quality rice cookers are also flooding the market. These inferior products usually have long-term use to emit toxic and harmful substances, toxic liner materials, irritating odors, carcinogenic risks, etc., which seriously affect the health of users. As a performance-oriented home appliance evaluator for many years, the following will explain the principle of the rice cooker, and do the four hidden dangers and risk science, I hope you have a correct and comprehensive understanding of the rice cooker.
(The picture above is some of the rice cookers I used in my evaluation)
1. Is the rice cooker a black technology?
Black technology refers to cutting-edge technology and innovative products with powerful functions and advanced thinking, and its principles and application methods obviously exceed the scope of traditional science and technology. Rice cookers in modern life, has been constantly updated and iterations, with more comprehensive functions, professional and high-quality rice cookers are indeed a kind of "black technology" products, can bring a lot of help to our lives. For example, the precise temperature control time function allows us to be confident about the food we eat. In addition, a quality professional rice cooker has a variety of features. For example, for porridge, steaming and other cooking methods, users can also set a unique time and temperature to complete the cooking task independently.
The main working principle of the rice cooker is to detect the temperature on the main thermostat and the sensor temperature on the upper lid in real time through a microcomputer chip. Once the rice cooker reaches operating temperature, the built-in hot plate will automatically activate so that the hot plate starts generating enough heat. The internal pot conducts heat when the built-in electric heating plate is in full contact with the inner pot, and then the inner pot conducts heat energy to the rice and water, so that they are fully heated. According to this principle, the advantages of a good quality rice cooker are also very obvious in the following four aspects.
Advantage 1: The cooking method is intelligent and convenient
The rice cooker has a built-in high-quality computer chip, program and sensor, which can improve the accuracy of temperature control. At the same time, it can intelligently and quickly adjust the heat conduction size and running time according to the cooking requirements of different foods to meet the various needs of users when cooking.
Advantage 2: Better cooking
The smart rice cooker uses advanced convection technology, which can make the heat more evenly distributed in the food, fully heat the rice in all directions, and improve the cooking effect.
Advantage 3: More functions
In addition to the basic rice cooking function, the smart rice cooker also has a variety of rich functions, such as steaming, stewing, baking, etc., which can meet the diverse cooking needs of users.
Advantage 4: Relatively energy-saving and environmentally friendly
Smart rice cookers use advanced heating technology and energy-efficient design to not only reduce energy consumption, but also minimize environmental impact by recycling and reusing wastewater.
Second, be wary of the four hidden dangers and shortcomings of inferior rice cookers
With the update and iteration of technology, rice cookers have brought great convenience to our lives, but the expansion and popularization of the market will also lead to the existence of some poor quality products on the market, which are usually reflected in poor workmanship and materials, and have certain potential harm to human health. Therefore, I have summarized some of the hidden dangers and disadvantages that may be brought about by inferior rice cookers to help users better identify and choose a high-quality rice cooker.
Disadvantage 1: When cooking rice in an inferior rice cooker, there will be a phenomenon of pinching and pasting the pot
Because the temperature control of the poor quality rice cooker is not accurate, the heating process can not be effectively controlled, and when cooking rice, there will be a situation of pinching or pasting the pot, which is caused by the uneven heating of the rice cooker, so that the rice is easy to paste the bottom under long-term high temperature heating.
Disadvantage 2: Emit toxic and harmful substances
Some inferior rice cooker liner coating materials are poor, and the coating thickness is thin, not wear-resistant and high-temperature resistant, the initial performance is very good, but the non-stick coating on the surface is easy to fall off after long-term high-temperature use, and in serious cases, it will be mixed into food, which is carcinogenic to human health.
Disadvantage 3: There is a fire hazard
Usually the power and heat of the rice cooker are very large, and the use of inferior wires, poor heating chassis materials and other reasons can easily overheat the rice cooker line, causing short circuits and causing fire and other safety problems.
Disadvantage 4: Release irritating odor, which is harmful to the human body
The rice cooker with poor material on the lid is prone to damage, aging and other problems, and is generally not durable, and the sealing rubber ring is of poor material, which is easy to produce a pungent odor at high temperatures, increasing the potential danger of carcinogenesis, and the harm to the human body is more serious.
3. Pay attention to the root cause of the hidden dangers of the rice cooker
The advantages and risks of rice cookers in the process of use have been summarized before, and I believe everyone wants to stay away from those inferior products. Since there are so many harms of inferior products, why can they still appear on the market? This requires us to explore the root cause, for this reason, I found a negative evaluation chart of old users of rice cookers (as shown below), through which we can intuitively see: the emission of toxic substances and poor manufacturing quality is the focus of many attention and criticism from users. In order to better avoid these inferior products with many negative slots, we must pay attention to the following root points.
Root cause 1: The behavior of fighting price wars leads to the prevalence of poor quality products
With the expansion of the rice cooker market, many merchants will use a variety of inferior raw materials in order to save costs and earn more profits. Although the price of rice cookers has decreased, the quality has also deteriorated. Many raw materials not only have poor high temperature resistance and corrosion resistance, but also are prone to produce toxic and harmful substances, which is very unfavorable to human health from a safety point of view.
Root 2: Don't trust the products endorsed by Internet celebrities and celebrities
In today's highly developed Internet, many brands have found online celebrities to live broadcast to sell products in order to have better visibility and sales. If you often listen to the propaganda of Internet celebrities in the live broadcast room, you will be more convinced, and ignore other considerations, resulting in the product may not be easy to use in the process of use. At the same time, many businesses spend too much on publicity and ignore the cost of product research and development and the cost of material selection.
Root 3, marketing "0" coating gimmick
Many businesses advertise "0 coating" on the market, which attracts many consumers. However, the inner liner of these products is made of stainless steel, which is very cost-effective to use. When cooking rice, there is sometimes a problem with sticking to the pan, and bacteria can also grow.
Root 4: Blindly believing that high power is a good product
Some users believe in the idea of the greatest possible power, believing that the more power you have, the faster it heats up. However, excessive power brings greater safety risks. Although high power can cook rice quickly, it will accelerate the insulation aging of electric heating elements.
After understanding the root cause of some inferior rice cookers emitting toxic and harmful substances and potential safety hazards during use, we will avoid buying those unprofessional products on the market and choose a really easy to use one to provide good help for our daily cooking. However, there are many factors to consider when choosing a quality rice cooker. While many brands boast of the superior performance of their products, there are various problems in the actual use of their products. Based on the above analysis, I cite statistics from a professional research agency on the test results of mainstream rice cooker brands in terms of performance, safety and non-toxicity. I believe that these data will have a good reference value for everyone to buy rice cookers.
The home appliance industry is mixed, and many big rice cookers have hidden safety hazards! For example, the problem of toxic liner materials and toxic substances emitted is frequent. Gong Ling's Internet celebrity rice cooker has been the hottest in recent years, as a professional veteran brand often exported to the European and American markets, it is rare to have the European Union, the United States and other countries certified, the original 13 highlights of black technology and the whole machine through the maternal and infant food testing, is the only one that can increase the uniformity of rice aging by 115% at the same time, the safety of food grade increased by 128%, and the release rate of toxic irritants is reduced by 128%, 0 heavy metal design, rare to obtain EU certification! Performance attenuation and other aspects, are the strongest within 1,000 yuan. It insists on not advertising, and purely relies on the word of mouth of in-depth users and the media, and continues to firmly occupy the first position in the list of mid-to-high-end sales and word-of-mouth.
In order to achieve pure safety and non-toxic fever performance and high durability, Gong Ling has continued to subtract product functions and intelligence, and has adhered to the technology of safety and performance for several years. It has made a lot of innovations in higher-level high-performance and safe and non-toxic technologies, such as the use of 5A finely researched thick kettle liners, 7 layers of corrosion-resistant and wear-resistant stainless steel cavity materials, to enhance the corrosion and wear resistance of the product, maternal and infant grade Maifan Stone 3.0 coating, high-temperature resistant and non-toxic design, and 6-year safe and non-toxic "anti-attenuation" design, etc., to promote faster heating efficiency, more accurate temperature control, and more reliable in safety and non-toxicity!
If you are interested in the entry style, you can go to Xiaomi, Midea, the design and workmanship in the same price segment are acceptable, and it has a certain cost performance. Among the high-end models, Toshiba can look at it, the price is relatively expensive, the design is exquisite, and the quality is not bad.
4. Eight tips for buying a rice cooker
Rice cooker is an indispensable small household appliance in a family kitchen, with the progress of science and technology, rice cooker is also constantly developing intelligently. So, after we have a comprehensive understanding of the advantages and disadvantages of rice cookers, how do you choose a good one among the many brands?
1. Priority is given to brands with strong professional and technical strength, safety and non-toxicity
Safety should be the primary consideration in the use of home appliances, and high-quality brand rice cookers will be technically adjusted according to factors such as heating method and structure, convection design, intelligent temperature control, cavity and heating uniformity, and the rice cooked by this rice cooker does not contain toxic and harmful substances.
2. Select the spiral simmering pressure heating method
In the rice cooker market, different rice cookers heat up differently. Among them, IH heating rice cookers are expensive, and the heat attenuation degree is high by using the principle of electromagnetic heating, and it is more of an IQ tax. The spiral simmering pressure heating can be in the form of pressurization, as well as the formation of spiral high-density surround heating heat, so that the heating is more uniform.
3. Prefer metal liners
The material of the inner tank of the rice cooker affects the heating performance and safety of the rice cooker, so it is recommended to choose a selective alloy inner tank with good thermal conductivity, good safety and durability, and high quality. Such an inner tank has a long service life, is anti-drop and anti-smashing, safe when heated, and is more suitable for long-term use. The inferior aluminum liner or stainless steel liner not only has unstable performance, but also worries that the product will volatile irritating toxic substances and heavy metals exceeding the standard after heating and use, which endangers physical safety and has carcinogenic hazards.
4. Wire
A good quality rice cooker will generally use more expensive pure copper wire to ensure that the rice cooker has no fire and other safety hazards, but some low-cost rice cookers use inferior wires in order to save production costs, and the safety hazards are great!
5. Coating material
It is recommended to choose Maifan stone coating, it will not stick to the pan like stainless steel coating. It ensures safety, eliminates sticking problems, and provides better resistance to high temperatures. The coating can also withstand high temperatures for a long time, so there are no safety issues during use.
6. Pay attention to the material of the top cover
304 stainless steel is a high-grade metal material, its top cover is more expensive, corrosion resistance and wear resistance durability are higher, there is no need to worry about rust and oxidation corrosion for long-term use, and the heat insulation of the rice cooker is better, and cleaning is more convenient. And it will not emit toxic and harmful substances, resulting in the risk of cancer.
7. Choose a full-pot inner tank and thick
The heating uniformity of the whole kettle liner is the best, and the whole kettle liner can be applied to a variety of cooking methods, which can better stimulate the original aroma of the ingredients and taste better. In addition, the thicker the rice cooker liner, the better, the thicker the liner, the more test the heating technology strength of the rice cooker, but also more textured, long-term use of high durability.
8. The difference between the design of convection valve/exhaust valve
When choosing a rice cooker, I recommend buying a rice cooker with a convection valve design, especially a high-quality shaped convection valve design. It intelligently controls the pressure in the pot, which effectively enhances the water absorption and taste of rice, and the use effect is better.
Rice cooker is not black technology?Rice cooker is an important household appliance in modern kitchens. Its emergence and development continue to solve the trouble of cooking for us and improve the quality of life. Moreover, high-quality and professional rice cookers also bring more beauty to family life with their own unique advantages, and at the same time pay more attention to safety and intelligence. On the other hand, inferior rice cookers will bring many defects and safety risks. Therefore, when buying a rice cooker, don't blindly follow the trend to buy, consider all aspects of performance, and look for a professional and high-quality brand!
