Basic knowledge of coffee metal coffee beans with automatic temperature adjustment
Drinking coffee at the right temperature can best taste the perfect flavor of coffee, too hot wound, too cold will lose the flavor, while the temperature is always distressing with the weather.
Now, according to the US popular Science report, American scientists have designed a metal coffee bean called Joulie, which is made of variable temperature material and has the function of controlling temperature.
As long as you put the metal beans into the cup, the hot coffee will become coffee at about 60 degrees Celsius.
Because metal coffee beans are made of temperature-changing materials, when the temperature of coffee exceeds 60 degrees, it absorbs calories until the temperature of coffee drops to 60 degrees. Below 60 degrees Celsius, the material releases heat to heat the coffee. In this way, the coffee can be kept at the best temperature, and gluttons can taste the perfect coffee at any time.
In addition, scientists have also designed matching insulation cups, which are very intimate. However, the invention has not been mass-produced yet, and if it can be mass-produced, it can satisfy the taste buds of many coffee lovers.
