Coffee brewing method hand brewing pot: an introduction to the history of hand brewing coffee and an analysis of its operation methods

Making coffee by hand allows you to quietly focus on such a wonderful thing. I like to collect my thoughts and adjust my mood in this quiet process. I feel as excited as waiting for the sunrise.

The pumps of coffee machine are volumetric pump, power pump and electromagnetic pump.

From the understanding of the principle of the pump, the pump can be divided into three types: volumetric pump, power pump and electromagnetic pump. The volumetric pump is pressurized by changing the volume of the cavity, such as plunger pump, rotary plate pump, gear pump. Power pump is the impeller rotation work to promote the liquid to boost, such as vane pump, centrifugal pump and so on. An electromagnetic pump is used to transport a good liquid conductor.

Starbucks goal: to

Starbucks goal: to "drive away" customers to become a coffee convenience store

In the positioning of Starbucks in China, white-collar workers are a state, not an identity. A considerable number of urban white-collar workers are literary youth and heavy consumers of coffee shops, but Starbucks will never place its position on the status of literary and artistic youth, even though they have a good chance of being the same person. Such an exquisite positioning has exposed the nature of Starbucks' split personality.

Answers to the Teaching problems of hand-made Coffee (1)

Many friends saw that I posted photos of the cadets' hand-made coffee in the moments, some of which were different from theirs in operation, and sent messages asking why they were different from theirs.

The thinking mode of extraction 2b-extraction time is transferred from Douban

Continuing with the previous article, http://www.douban.com/note/244706236/ extraction time looks easy, but it's actually a little more complicated than I thought. Because although the extraction time is directly related to the relationship between extraction rate and concentration, their relationship is not necessarily proportional. We still return to the original two purposes, get the reasonable extraction rate and get the proper concentration.

Fine Coffee study on the amount of Coffee Powder in brewing Coffee

Fine Coffee study on the amount of Coffee Powder in brewing Coffee

In the second article, we mentioned the scraper, which allows you to control the amount of powder, but the disadvantage is that it will waste the amount of powder. In fact, it also has a limitation, if a filter bowl can hold 18g powder, the scraper can only control the amount of powder by scraping off the powder. So the upper limit of the powder bowl of 18g is only 18g. Of course, some baristas know that coffee can be made by patting a filter bowl filled with coffee powder.
