Nowadays, China has experienced the looting of the May 4th Movement and the Cultural Revolution, and Chinese studies have become increasingly popular. With the improvement of people's quality of life, health preservation is also a topic and pursuit that people relish. As a kind of "utensil" in keeping in good health, it is a reunion day that has accompanied and left the iron pot for thousands of years. Water is the mother of tea, and pot is the father of tea. Lu Yu's Tea Classic ranks third in the moisture content of tea: "Above the mountains and rivers, in the river and underground." Mountains and rivers are mountain springs. Natural water is filtered and flowed layer by layer, but at the same time, it also incorporates mineral components beneficial to human body, and the beneficial trace components are higher, and iron ions in mineral components are one of the main components.
Sweet mountain spring water has high iron content. Using Duhetang iron pot to boil water can not only adsorb chloride ions in water, raise water temperature and soften water quality, so that the boiling effect is better than that of pottery pots and glass pots, but also release ferrous ions to realize the "mountain spring effect", making the water sweet and smooth, and the taste is thick and full.
In addition, the iron pot in Duhetang can easily distinguish the boiling degree of water. "Its boiling, like the whisper of a fish's eye, is a boiling, and its side is like a fountain Julian, which is a second boiling; Make waves, drum waves are boiling. The water on it is too old to eat. " Taking the miracle of making tea as "the water is just boiling" is a method that iron pots can't distinguish at all. Iron ore with geological gas accumulation is the raw material of iron pot. Duhetang uses first-class gray iron, which has strict requirements for decarbonization. The inspection and testing of raw materials are strictly controlled according to the functional requirements of the iron pot. Duhetang's proprietary crystallization technology of high-temperature walnut oil inner wall makes the iron pot tea closer to nature and releases iron ions and beneficial trace elements needed by the human body without obstacles.
The effect of iron supplementation in iron pan by using high temperature walnut oil inner wall crystallization technology is quite good Scientists have long discovered that iron is a hematopoietic element, and adults need 0.8- 1.5 mg of iron every day. Severe iron deficiency will affect intellectual development. Experiments have also proved that the pure and broken iron pot can release ferrous ions easily absorbed by the human body when boiling water, supplement the iron needed by the human body, and effectively prevent and treat various iron deficiency symptoms. Using Duhetang iron pot to boil water, on the one hand, the iron pot will absorb chloride ions in the water, on the other hand, the iron pot will release ferrous ions in the boiling water. The human body cannot directly absorb metallic iron. Iron in food generally exists in the form of trivalent iron. First, the food is digested, and the gastric acid can react with iron to dissolve, and then the oxide is reduced to lose oxygen and combine with hydride to generate bivalent iron.
It is mainly absorbed by the human body in the duodenum. In terms of absorption rate, the absorption rate of bivalent iron is 15%, and that of trivalent iron is only 3% to 8%. Iron containing bivalent iron is the most useful of all states. So it can supplement the iron that the human body needs every day. It can also prevent and reduce hypertension, which is very helpful for patients with hypertension. Boiling water in an old iron pot can not only raise the water temperature, but also soften the water quality, making it sweet and smooth, with a thick, full and smooth taste.
When you drink good tea, you get twice the result with half the effort, which is especially suitable for making old tea or boiling tea. Therefore, with pig iron as raw material and the author's artistic attainments, the special culture of the old iron pot has been formed. Not all iron pots can achieve the "mountain spring effect"
At present, most daily-use iron pots belong to products on industrial production lines. It directly adopts modern metal treatment technology, such as non-stick pan inner wall treatment technology, and even simpler spraying technology and enamel technology, thus bringing in unhealthy chemical elements. Or the iron wall is completely closed, so that iron ions cannot be released into the water, thus losing the health care value of the iron pot.
Treatment of inner wall of high temperature walnut oil in Duhetang iron pot
Duhetang always believes that "the iron pot that is repaired both inside and outside is the best iron pot", and has established four concepts of health, safety, practicality and beauty since its birth. We developed our own advanced inner wall treatment technology of high-temperature walnut oil, which solved the contradiction between rust prevention and iron ion release, realized the ideal of perfect mountain spring effect, and was simple and convenient to maintain.
Iron pot originated in China and was perfected in Japan. Duhetang had an in-depth exchange with Mr. Ruto Zhuoshi, the ninth generation successor of Japan Customs Office. The atomized franc technology is a perfect qualitative change of iron pot technology, which breaks through the predicament and solves the practical problems. Duhetang Iron Pot combines painting, calligraphy, sculpture, seal cutting and other arts in the process of iron casting and forging, which is due to the harmony of history. Sometimes, the weather is full of vitality, people are healthy, technology is controlled, art is beautiful and six in one. Combining function and art, she is an indispensable companion of poetic life. Her simple, heavy and atmospheric style contains elegant temperament, just like a bosom friend, which can accompany her for life.
