What is the principle of ice burial? What is the difference between ice burial and cremation? A pilot project will be carried out in Wuhan

In China, corpses were disposed of by burial in the past. In 1997, cremation began to be mandatory across the country. In the near future, ice burial may become mainstream, and it will be piloted in Wuhan. The characteristic of ice burial is high technology. It freezes the corpse directly, then crushes it into pieces, and finally puts it in an organic coffin and buries it in the cemetery. Let me briefly introduce it to you. 1. What is the principle of ice burial? Modern ice burial: The body of the deceased is placed in liquid nitrogen for processing, which can quickly freeze the body. The principle is to use the liquefaction of nitrogen. It is understood that for nitrogen to enter a liquid state, a low temperature of -196°C is required. When the body is soaked at this low temperature, the organic tissues will quickly become dehydrated and the whole body will freeze quickly. Using ultrasonic waves, the body will be powdered into ashes. Ice burial background: In fact, the real ice burial is the burial custom of the North American Eskimos. When the old people there feel that they are going to die, they will ask their sons for an animal skin. If the son understands, he will prepare an ice cave for his father to lie in. Cover it with animal skins and seal the entrance of the cave with ice, and the father will die peacefully. Five days later, a small hole will be dug in the ice cave to allow the father's soul to leave the ice cave and ascend to heaven. 2. The whole process of ice burial

1. Within 12 days after death, the staff will refrigerate the body in a freezer at minus 18℃;

2. Then, put the body into -196℃ in liquid nitrogen to make the body brittle;

3. Afterwards, the staff put the frozen body into a vibrating instrument and shook it slowly to shake the body into powder;

4 1. Vacuum the corpse powder to evaporate the water, then filter the corpse powder to remove impurities, then place it in an organic coffin made of sorghum flour or potato flour, and finally bury it in the cemetery. 3. Ice burial will be piloted in Wuhan

On February 22, 2011, South Korea introduced ice burial technology to China. This world-leading green burial technology has aroused strong interest among funeral experts in Wuhan. A pilot project was conducted in Wuhan. This equipment uses nitrogen chloride to quickly freeze the body to minus 196 degrees Celsius, and uses vibration to instantly turn the body into ashes. Compared with the current cremation method, this technology is energy-saving and environmentally friendly, and is slightly more expensive than cremation equipment. 4. What is the difference between ice burial and cremation?

The similarity between ice burial and cremation is that the body is processed into ashes. The difference is that cremation requires the body to be cremated, which will cause environmental pollution problems and feels very cruel; The ashes produced under ice burial conditions can easily decompose under natural conditions and return to the ecological cycle of nature, thus fulfilling the deceased's wish to return to their roots. However, ice burial is more expensive than cremation, so it is difficult to promote it!
