Like China, most people in Japan eat rice.
It is even worse than that. In most parts of northern China and northwest China, pasta is still the staple food.
Almost all people on the Japanese island eat rice.
Therefore, how to cook a good pot of rice is a very important skill for housewives in Japan.
In the past, when electric rice cookers had not yet been invented, being able to cook rice instead of leaving it undercooked was already a very good ability.
If you can accurately control the heat and water and cook the rice to make it fragrant and soft, it can definitely be considered a skill that can be used to make a living.
According to the Japanese people in later generations, he should be called "Rice Immortal"
so……
With the advancement of technology, the Japanese were the first to find ways to improve cooking utensils.
For example, in 1923, Mitsubishi Electric developed the prototype of the world's first rice cooker.
However, at that time, electric rice cookers were mainly used for cooking by the crew on the ship and were not used in ordinary households. Moreover, the effect was not very good.
It wasn't until the 1940s and early 1950s that companies such as Mitsubishi Electric and Matsushita Electric introduced household rice cookers with built-in heating coils.
However, at this time, the rice cooker can only be regarded as an assistant in cooking, and it is not yet able to cook fully automatically. It still requires manual monitoring and power off at the appropriate time.
If you are not careful and forget to turn off the power, the rice cooker will overheat and even cause serious consequences such as fire.
Therefore, at that time, rice cookers were not widely popularized in Japan.
It was not until 1955 that Japan's Toshiba Corporation launched the world's first truly automatic household rice cooker. It adopted a double-layer pot structure and utilized the principle of water vapor to achieve automatic cooking.
This solves the most troublesome temperature control problem during the cooking process.
Since then, the rice cooker has been considered a mature household appliance and has rapidly entered thousands of households in Japan, liberating many Japanese housewives who could not even cook rice properly.
Subsequently, companies such as Toshiba and Panasonic continued to improve rice cookers.
The rice cooker is given a timing function, and its structure is simplified, thus improving the efficiency of cooking.
But even so, by 1977, even with the best Toshiba rice cooker in Japan, it would take at least 25-30 minutes to cook a pot of decent rice.
For the Japanese, who are particularly particular about work efficiency at this time, this is still a relatively long waiting time.
In particular, many Japanese housewives often forget to cook rice because they are busy with other housework.
When all other dishes were cooked and the family came back, they found that the most important rice was not cooked.
Therefore, even if you wash the rice and put it in the pot immediately and cook it in an electric rice cooker, you will still have to wait at least twenty minutes before you can eat it.
Jiro Oda himself felt deeply about this.
His wife is a careless person and often only remembers that she didn't cook rice after he gets home from get off work.
Therefore, Jiro Oda often had to wait very late to eat rice after returning home.
And for some reason, the rice cooked by my wife using the Hitachi rice cooker has a bad taste and texture.
so……
When Lin Huowang casually said that the rice cooker he designed could quickly steam rice and make the rice taste softer, Oda Jiro became excited.
"You are kidding, right? Lin Huowang, why do I find this unbelievable?
Look at your poor countryside. Ordinary people don’t even have electrical wires in their homes, so it’s impossible for them to have any household appliances.
But you told me so confidently that you invented a new solution for rice cookers. "
Jiro Oda really had no choice but to question it, because all the basic conditions in Chinese cities and rural areas that he had seen in the past few days, and the capabilities demonstrated by the forest fires, formed a very strong sense of tearing.
Logically speaking, it is impossible that in a soil with such a low rate of electrification penetration, there will not be a genius like Lin Huowang who is good at electrical appliance design!
Lin Huowang also knew that Oda Jiro's suspicions were reasonable, so he did not explain too much and spread his hands and said:
“Oda-kun, whether you believe it or not.
The fact is, I have such a plan in my hands.
I can even reveal some details to you in advance. I use the different expansion coefficients between two different metals to achieve a special [bimetallic strip dynamic temperature control system].
According to my design, the cooking temperature can be precisely controlled at 103 degrees Celsius with slight pressure, which is the optimal gelatinization temperature of rice.
In this way, the speed of cooking rice can be more than 40% faster than those traditional Japanese rice cookers.
Do you know what this means, Oda-kun? "
At this moment, Jiro Oda no longer had the arrogant feeling he had before.
Especially after Lin Huowang explained the principle behind it, Oda Jiro became even more convinced.
Because, during his years at Hitachi's small appliance division, he had heard scientists propose more than once that similar principles could be used to achieve precise temperature control of rice cookers.
But it is very regrettable...
Hitachi Group has so many highly educated and capable material scientists, and has spent so many years, but still has not found a suitable material to form such a bimetallic dynamic temperature control system.
