How to buy American Coffee Machine

Because there is nothing to develop in the function of the American coffee machine, so it is mostly on the appearance of the style, of course, the factory is also working on how to reduce costs. Although the American coffee maker is simple, can you buy it casually when you buy it? Since the functions are all the same, is it the cheaper the better? In fact, this is not the case, let's talk about the selection and purchase of American coffee machines.

Guide to the selection and purchase of American coffee machines

When choosing a coffee machine, you should first pay attention to the material of the machine, that is, the quality of plastic. The choice of plastic is in line with food safety, and many other people may smell a strong smell of plastic when using American machines, which is because the plastic used is not good. You can hardly smell plastic when you brew coffee with good plastic. But at present, in order to reduce costs, some domestic factories use recycled plastics to produce multi-purpose black, black can cover up some impurities of recycled materials, if the machine is made into white, you can better see whether the materials are good or bad. In addition, we should also pay attention to the thickness of the machine plastic, some machines may be in order to reduce costs, the machine wall is very thin, with the finger press or pressure can obviously feel. The thin wall is easy to cause damage, and the thin wall will also make the plastic smell more prominent when heated.

Secondly, when you choose and buy a machine, you must choose porous hot water. The more holes, the finer the better, generally at least 9 holes, as is the case with many American-style pores. At present, many American machines sold online and many machines in domestic shopping malls produce water from a single hole, which is very unreasonable. A large hole to produce hot water can easily lead to excessive intermediate extraction and insufficient edge extraction. If hot water comes out from a single hole, it will seriously affect the extraction effect.

There are many ways to heat the American coffee machine, adding the flow limiting valve or increasing the power is to make the water temperature higher and heat faster. Better machines will use semi-enclosed heating methods similar to boilers: stainless steel boilers have spiral heating copper tubes. The water temperature of this American machine for brewing coffee can reach 92mur96 degrees. The water from the average American machine is only more than 80 degrees, which is obviously too cold for coffee. If the water temperature is solved, consider how to fully soak the coffee powder in hot water, usually with filter paper. If it can be equipped with a gold filter like Swiss gold swissgold, the effect will be better.

Finally, the American coffee machine, whether it is the simplest or electronically controlled, will have automatic heat preservation. That is, when the water is finished when brewing coffee, the machine can enter the state of automatic heat preservation without turning off the machine. In order to drink as much of the aroma of coffee as possible, an American coffee machine with a lower heat preservation temperature. Of course, it is best to cook and drink.
