Deciphering Japanese rice cookers: Technology is not difficult

At the moment, the Chinese have gone to Japan to sweep the goods. A major purchase is the Japanese rice cooker. In fact, the Japanese rice cooker is not technically difficult, but it is also prominent in the material. Some researchers pointed out that basically, we can summarize the advantages of Japanese rice cookers into two points: advanced heating method and excellent inner liner technology. The heating methods of Japanese rice cookers are mainly divided into four types: traditional chassis heating, IH electromagnetic heating, IH electromagnetic pressure heating, and gas heating. Most of the domestic is the first traditional chassis heating.

When interviewed by Professor Yao Yong, an expert on smart home research at the Engineering Research Institute of Guangzhou University of South China University of Technology, he told reporters: “Japan’s products are good and the coating is more durable. There is indeed a gap in the durability of domestic rice cookers. To put it bluntly, the merchant sacrificed the durability of the original for cost reasons. In addition, the innovation in design is also much worse. More is like a cottage, not a creation.

Some studies have pointed out that from the price point of view, the traditional chassis heating is the cheapest, basically less than 500 yuan. The price of IH electromagnetic heating is slightly more expensive, at 500 yuan or more. For pressure IH, the price will cost more than a thousand yuan, and the higher end will cost even seven or eight thousand dollars. In terms of liner material, the domestic liner material is roughly divided into: general alloy aluminum liner, stainless steel liner, ceramic liner. There are also differences in technology, such as pure copper liners, charcoal liners, soil liners, and iron liners. For example, the pot material used in a high-end rice cooker in Japan is a traditional Japanese handicraft. The southern ironware is well-known in the iron industry. When iron cookware is used for cooking, the ferrous ions are continuously released into the tea and food, and the iron which is easily absorbed by the body can prevent anemia. The iron itself has fine irregularities and pores, making it easier to retain and conduct heat. It also heats the food evenly during cooking, preserving the delicious taste of the ingredients. Even the water cooked through the iron is more clear on the palate. The long carbon coating process used in a rice cooker liner in Japan is also known worldwide. According to reports, the charcoal is made by carbonizing 1300 ° C, the best material in charcoal, adding a long carbon coating to the inner pot, which can increase the far-infrared emissivity of the inner tank and make the fine water The molecules are directly connected to the rice core, and the rice grains are fully absorbed and expanded, and the cooked rice is more soft and delicious.

In short, in terms of craftsmanship, the Chinese need to use more hard work to truly improve the quality of life of the people.
