The basic principle of American coffee machines is the same. The water is heated, flows through the coffee powder, and flows out through the filter paper or filter into the glass pot, which becomes coffee.

Because there is nothing to develop in terms of function, most of the focus is on appearance and style. Of course, the factory is also working hard on how to reduce costs. Although the American coffee machine is simple, can you just buy it when purchasing? Since the functions are the same, isn’t the cheaper one the better? In fact, this is not the case. Let’s talk about the purchase of American drip coffee machines.

When choosing a coffee machine, you must first pay attention to the material of the machine, which is the quality of the plastic. The first choice of plastic is food safety. In addition, when many people use American-style machines, they may smell a strong plastic smell. This is because the plastic used is not good. When you use good plastic to make coffee, you basically won’t smell the plastic smell. But at present, in order to reduce costs, some domestic factories use recycled plastics to produce plastics mostly in black. Black can mask some impurities in recycled materials. If the machine is made white, the quality of the materials can be better seen. In addition, pay attention to the thickness of the machine's plastic. Some machines may have made the machine wall very thin to reduce costs, and you can clearly feel it when you press or press it with your fingers. Thin walls can easily cause damage, and thin walls can also make the plastic smell more prominent when heated.

Secondly, when purchasing a machine, be sure to choose a multi-hole hot water outlet. The more holes and thinner the better, usually at least 9 holes, which is what many American multi-hole machines have. At present, many American-style machines sold online and many of the machines in domestic shopping malls have a single hole for water outlet. This is very unreasonable. One large hole for hot water can easily lead to over-extraction in the middle and insufficient extraction at the edges. The American-style machine itself is Coffee has been criticized. If hot water comes out of a single hole, it will seriously affect the extraction effect.

American coffee machine owners have many methods for heating. Adding a flow limiting valve or increasing the power are all to make the water temperature higher and heat faster; better machines will use semi-closed The heating method is similar to that of a boiler: there are spiral heating copper tubes inside the stainless steel boiler. The water temperature of this American-style machine for brewing coffee can reach 92-96 degrees. The water flowing out of the general American-style machine is only more than 80 degrees, which is obvious for coffee. Too cold. If the water temperature is solved, consider how to fully soak the coffee powder in hot water. Generally, filter paper is used. If it can be equipped with a gold filter similar to Swissgold, the effect will be better.

Finally, American coffee machines, whether they are the simplest ones or those with electronic control functions, will have an automatic keep-warm function. When the water is finished boiling when making coffee, the machine does not need to be shut down and enters the automatic keep-warm state. In order to drink as much coffee aroma as possible, use an American coffee machine with a lower heat preservation temperature. Of course, it is best to cook and drink immediately.
