Because there is nothing to develop in function, most of them make a fuss about appearance and style. Of course, factories are also trying to reduce costs. Although the American coffee machine is simple, can you buy it directly when you buy it? Since the functions are the same, isn't the cheaper the better? Actually, it's not. Let's talk about the purchase of drip coffee machines in the United States.
When choosing a coffee machine, we should first pay attention to the quality of the material of the machine, that is, the plastic. The choice of plastic conforms to food safety. In addition, many people may smell strong plastic when using American machines, because the plastic used is not good. When you make coffee with good plastic, you can hardly smell the plastic. However, in order to reduce costs, some factories in China use recycled plastics to produce multipurpose black, which can cover up some impurities in recycled materials. If the machine is white, you can see the quality of the material better. In addition, we should also pay attention to the thickness of machine plastic. Some machines may make the machine wall very thin to reduce the cost, which can be obviously felt by pressing or pressing with fingers. Thin walls are easy to cause damage, and thin walls will also make the taste of plastic more prominent when heated.
Secondly, when buying a machine, you must choose porous hot water. The more holes, the finer the better. Generally there must be at least 9 holes. Many American porous pipes are like this. At present, many American machines sold on the Internet and many machines in domestic shopping malls are all out of water through a single hole, which is very unreasonable. A big hole produces hot water, which easily leads to excessive extraction in the middle and insufficient extraction at the edge. The coffee made by American machines itself has also been criticized. If hot water is generated from a single hole, it will seriously affect the extraction effect.
There are many ways to heat American coffee machines, such as installing a flow-limiting valve or increasing power, in order to make the water temperature higher and heat faster; A better machine will adopt a semi-closed heating method similar to a boiler: the stainless steel boiler is equipped with a spiral heating copper tube. The water temperature of this American machine for brewing coffee can reach 92-96 degrees, while the water from the general American machine is only over 80 degrees, which is obviously too cold for coffee. If the water temperature is solved, we should consider how to fully soak coffee powder in hot water, generally using filter paper. If we can match a gold filter similar to swissgold, it will be effective.
Finally, the American coffee machine, whether it is the simplest one or one with electronic control function, will have automatic heat preservation function. That is, after the coffee is cooked, the machine can enter the automatic heat preservation state without shutting down. In order to drink the aroma of coffee as much as possible, the American coffee machine adopts a lower heat preservation temperature. Of course, it is best to be able to cook and drink immediately.
