Warm coffee beans

So you need a few concept heat preservation "coffee beans": Coffee Joulies. It comes from the invention of mechanical engineers Dave Petrillo and Dave Jackson, who grew up together and found that drinking coffee is actually a technical job-temperature is very important, too hot to say, if it is cold, the flavor will be much weaker. As a result, the two came up with the idea of making this concept of thermal insulation "coffee beans" (it is obviously not used to grind coffee beans). To put it simply, it is a round coffee bean-shaped metal, but it is much bigger, and its crystal shell makes it look clean and comfortable. The interior of "coffee beans" is made of some kind of material with a melting point of 60 degrees Celsius. When drinking coffee, throw a few of these "coffee beans" in, they first absorb heat and melt, so that the coffee can be reduced to about 60 degrees at three times the speed. Then, the heat is slowly released and solidified, slowing down the cooling rate of the coffee from 60 degrees to the original 1max 2, thus prolonging the best flavor temperature time.

In addition, I have to mention that the concept of thermal insulation "coffee beans" (Coffee Joulies) packaging is quite lovely, in small cloth bags, poured onto the table, crackling, while a number of cloth bags are packed in wooden boxes, like cigars, feel like luxury goods.
