Various utensils and principles for making a good cup of coffee

■ Belgian Pot / balanced Saifeng Pot (Balancing Syphon): the Belgian kettle is the same as the siphon kettle. It also uses the thermosyphon principle to extract coffee. At the same time, it also skillfully uses the lever principle. The kettle body is divided into two parts. We temporarily call it the heating kettle and the extraction kettle. Pour the ground coffee powder (thick and thick as the siphon kettle) into the extraction kettle and heat the kettle with an alcohol lamp. When the water is close to boiling, there will be bubbles to press the water into the extraction kettle and soak the coffee powder. after almost all the water is pressed into the extraction kettle, the body of the heating kettle becomes lighter and tilted up through the principle of lever, and the cap of the alcohol lamp is automatically capped. The heating kettle begins to cool, and the coffee liquid from the extraction kettle flows back to the heating kettle, so that the coffee is ready. Belgian pot is a very ornamental way to make coffee. To put it simply, it makes people feel high-end and high-end.

■ Philharmonic pressure (Aeropress): it was officially released by AEROBIE Company in 2005. Its structure is similar to that of a syringe. When in use, put ground coffee and hot water in its "syringe", then press the putter, and the coffee will flow into the container through the filter paper. It combines the immersion quenching method of the French filter pressure pot, the filter paper filtration of the follicular coffee, and the fast, pressure quenching principle of Italian coffee. By changing the size and pressing speed of coffee grinding particles, users can cook different flavors according to their own preferences. In addition to being fast, convenient and effective, its cleaning and maintenance is surprisingly simple-it takes only a few seconds after use. The Philharmonic pressure also has the advantages of short size, light weight and not easy to damage, so it is quite suitable to be used as a coffee brewing apparatus for going out.
