Types of coffee machines

There are various types of coffee machines in the market, and their functions are also different. You can choose a suitable coffee machine according to your personal needs.
Here are some common coffee machines:
1. A fully automatic coffee maker is a type of coffee maker that eliminates manual operation and can automatically brew coffee. This type of coffee maker can grind, fill, and make coffee, and some even add hot milk to make milk coffee. Because with the development of the coffee machine market, the so-called "fully automatic coffee machine" is no longer limited to coffee machines that complete grinding, filling, pressing, filtering, boiling, and cleaning with just one click. It has developed many new functions according to user needs, such as adjusting the thickness of grinding beans, making ESPRESSO and CAPPUCINNO coffee, etc. The structure of a fully automatic coffee machine is relatively complex, but it is convenient, fast, of consistent quality, efficient, and has a wide variety. However, it requires good maintenance and high maintenance costs. At present, the brands of fully automatic coffee machines include several common household or office brands such as DelongHi Delong coffee machine, Seaco coffee machine, Wister coffee machine, Jura Yourui coffee machine, Philips Xike coffee machine, etc; In addition, the current popular coffee machine and capsule coffee machine can also be called fully automatic coffee machines. However, the difference between these two and traditional coffee machines is that they use coffee semi-finished products such as coffee bags and coffee capsules instead of coffee beans.
2. A semi-automatic coffee machine is a professional coffee machine compared to a fully automatic coffee machine, as it cannot grind beans and can only use coffee powder. The operator needs to fill and press the powder themselves, which involves the process of coffee making. Therefore, it is called a truly specialized coffee machine.
Its characteristics include:
(1) Constant water temperature;
(2) Stable pump pressure;
(3) Steam is constant pressure and dry, easy to operate, etc; The semi-automatic coffee machine is mainly produced in Italy, with a simple structure and easy maintenance. By using the correct method, high-quality Italian coffee can be produced; Its famous brands mainly include FAEMA, RANCILIO, SYNESSO, LaPavoni, laCimbali, NuovaSimonelli, Boslio, Severin, Tchibo, etc.
3. The drip coffee machine is a classic drip filter. Simple, efficient, reliable, suitable for public use. The working principle of a drip coffee machine is also relatively simple. It includes a funnel for placing filter paper and coffee powder, and an essential device for filtering coffee is required. If you choose to use a drip coffee machine, you will inevitably need to purchase filter paper.
The classic style of a drip coffee machine is a V-shaped funnel on top and a portable coffee pot on the bottom.
4. As the name suggests, a high-pressure steam coffee machine is a combination of pump pressure and steam pressure. The drip coffee machine mentioned above uses an atmospheric pressure when brewing coffee, that is, it brews under normal pressure, while the pump coffee machine uses the principle of pressure. When brewing coffee, the pressure of water is greater than one atmospheric pressure, usually 5-19 atmospheric pressure, to quickly extract the essence of coffee. The coffee brewed is more fragrant, and there will be a layer of oil foam.
Precautions for using a coffee machine
Although the coffee machine is very convenient and simple to use, there are still some things worth noting.
1. Do not use the coffee machine without water.
2. Before operating the coffee machine, please note that it can only be used when the boiler pressure pointer reaches the green area (1-1.2 bar); When using, the temperature of the steam rod, the nozzle of the hot water outlet, and the cooking outlet is very high. Please do not expose your hands nearby to avoid damage caused by high temperatures.
3. Pay attention to observing whether the water pressure value on the pressure gauge is in the green area (8-10bar) when the stabilizing motor is pumping water.
4. To prevent overheating hazards, please keep the power supply smooth and the ventilation inlet and outlet unobstructed; Do not cover the warm cup holder with towels or similar items except for the cups and plates.
5. The cup must be completely dry before it can be placed on the warming cup holder; Do not place any items on the warm cup holder except for cups and plates.
6. If you do not use the coffee machine for a long time, please turn off the power and completely release the pressure inside the machine boiler.
7. Any accessories of machinery and equipment should not be brushed with items such as iron wire or steel brush; You must use a damp cloth to carefully scrub.
8. Place an appropriate amount of coffee powder into the handle of the filter cup and carefully compact it with a press handle. Note: Do not leave coffee grounds on the edge of the filter cup, as this will prevent air from entering during the cooking process, reducing pressure, and extending the lifespan of the cooking head gasket.
9. Please insert the filter cup handle tightly into the cooking head socket. Otherwise, during production, the handle will pop open due to excessive pressure.
10. After each use of the coffee machine, the power should be cut off in a timely manner and the cleanable parts of the coffee machine should be cleaned briefly.
11. After cleaning the coffee machine, use a soft dry cloth to wipe off excess water and place the machine in a dry and ventilated environment.
