Some products, technology is always far ahead, never out of date. Gourmet thermos is a good example.

The reason why culinary masters can sit firmly on the throne of the world's largest thermos bottle has a market share of 60%. The main reason is that the chef has a unique vacuum heat-breaking technology.

According to the principle of physics, if the air in a closed space is evacuated, then this area will become the best thermal insulator. That's what thermos bottles do.

The magician's stainless steel thermos has gone through at least twenty production processes; The container with outer bottle and inner container is made of double-layer stainless steel metal by stamping and welding, and then the sealing area between the outer bottle and the inner container is vacuumized to block the diffusion of convection heat transfer inside and outside the container, so as to minimize the influence of heat conduction effect on the container contents at room temperature, and the vacuum coefficient determines the performance of the thermos. In other words, a thermos bottle filled with hot water, the closer the outer bottle feels to room temperature, there is no fever, indicating that the vacuum pumping technology is better. thermos flask/bottle

According to the actual test results, the hot water can still maintain a high temperature of about 70 degrees Celsius after six hours. However, in the second hour, the temperature of the general commercial thermos has dropped to 26 degrees Celsius. It can be seen that the vacuum heat insulation technology of thermos bottles is far superior to ordinary thermos bottles (see attached table), which is the key to the best-selling thermos products all over the world and makes thermos bottles synonymous with thermal insulation products.
