Hand coffee filter cup is very knowledgeable! Flow rate data of several common coffee filter cups

This seemingly ordinary filter cup actually has a lot of history. it is the Japanese so-called "god of coffee" Taguchi, the only designated coffee filter in the "self-baking Ka Ka" run in Tokyo; if you add this glass pot designed with a special handle and refer to the hand-brewing techniques revealed in the books, you can be sure to brew the coffee with the help of God, as if you are in front of the bar of Baja Cafe!

This filter cup is highly valued in the Japanese coffee industry, this time it is not the ordinary model, but the new model launched this year, which has made some changes in the details and vaguely conveys the trend of Japanese hand-made coffee. It presents a trapezoidal structure, which is divided into small, medium and large sizes, while the discharge holes are divided into 1, 2 and 3 according to the size. According to the original factory, the flow speed is adjusted by the number of holes, so that the filter cups of different sizes can be consistent in the extraction time, which is rare in other brands.

This filter cup is jointly developed by Sanyo according to Mr. Taguchi's concept of hand flushing. It has a smooth and meticulous ceramic surface, which makes the flow smooth and durable. The deep water diversion groove extends to the outlet, creating a gap between the filter paper and the bottom, which is also one of the reasons for the fast flow, which will be more perfect with the original filter paper.

The new Sanyo filter cup increases the aperture of the bottom outlet. According to the actual measured data, the flow speed is about 1 / 4 faster, which is very close to the new tapered filter cup of other brands. At the same time, another tapered ceramic filter cup, which has a very high market share, will also speed up the water flow by about 1ppm 3. Does this tell us that the fast rush technique will lead the trend? Ceramic filter cup NT$600; glass pot NT$550, are Sanyo industry.

In order to draw a 3D picture and share my observation on the internal structure of the ceramic platform-shaped filter cup (or fan-shaped filter cup), the design of the bottom rib of the cup has a lot to do with the extraction efficiency.

The blue picture shows the first-line filter cup structure, which was first used by Melitta, and later can be seen in Bonmac, UN caef, Zero Japan and many filter cups, while the yellow image shows the Sanyo filter cup structure, which is famous for the use of the Baja Cafe in Taguchi.
