Ultra-simple rotary filter coffee cup

The rotary filter coffee cup is super simple, it is really cool to use, put the two cups together, press down, rotate, two movements, the coffee is ready to drink immediately, the shape is a cup-like, and there are no extra accessories. The brewed coffee is in the inside cup, and the outside cup plays the role of heat preservation, which is really super simple.

So where is its technical content? What about the coffee made?

1, it can use fine powder to make coffee, will it drink dregs with fine powder? The answer is no.

The rotary filter coffee cup consists of two sets of cups, in which the cup with a filter screen filters the coffee, but here its other function is to sift the coffee powder and remove the over-fine coffee powder before brewing the coffee. (note: too fine coffee powder is the enemy of coffee taste, and it is also the direct cause of frequent drinking of powder). The sifted coffee powder is then poured into the outside cup to brew. Because the coffee is brewed with fine powder, the brewing time is greatly shortened (the water temperature is stable, the quality of the coffee is guaranteed), and then through the rotating extrusion of two cups, more of the essence of the coffee is extracted, and the coffee is more fragrant.

2, the rotational extrusion force of the two cups depends entirely on my own feeling, the extruded coffee cake is left at the bottom of the cup without caring about it, it will no longer affect the taste of the coffee in the cup.

What about the corresponding "French filter coffee pot" and "enhanced version of the French pressure pot AeroPress"?

None of them can sift through the coffee powder. If you want to sift through, you have to find another sieve.

The filter screen of "French filter coffee pot" is generally thick, easy to drink powder dregs, and the brewing time is too long to ensure the stability of the brewing water temperature. more importantly, after brewing good coffee, find another coffee cup to pour out. Because the coffee left in the bottom of the pot was not squeezed, a lot of coffee essence was discarded.

One of the improvements of the French filter coffee pot is the "portable cup" that you drink directly after pushing down the filter screen, which solves the problem that the French filter coffee pot needs another coffee cup. But other problems remain.

The enhanced version of AeroPress uses filter paper to filter the coffee powder, filter out the fine coffee powder, and increase the pressure to make the coffee powder into a cake, and the coffee liquid is pressed directly into the coffee cup.

Relatively speaking, the coffee made by the enhanced French pressure pot AeroPress is stronger than the French filter coffee pot and does not drink powder. But the procedure of making coffee is more complicated. Several utensils, cups can not be less.

Thus it can be seen that the rotary filter coffee cup is an ultra-simple coffee brewing device, and there is no coffee utensil comparable to it. And its structure determines that it is very convenient to carry, it can make coffee, tea, or as a general water cup, it is very practical.
