The principle of the drip coffee maker

If you have decided to purchase a small coffee machine in your home or office, then an drip coffee maker would be an excellent option. Consider how the drip coffee maker works and what you should pay attention to when choosing it.

Scheme of work

The principle of operation of the drip coffee maker is a special filtering of coffee - water is passed through the ground beans, which are in a special filter. The coffee pot itself consists of two compartments: cold water is poured into a glass tank, and ground beans are poured into a container with a filter called “custard knot”. After loading all the ingredients, the start button is pressed and the brewing process begins.

Cold water goes down to the heater located in the lower part of the coffee maker.When heated, steam is formed, which subsequently rises through a special tube to the custard node. And already there is a brewing process. The temperature in the coffee compartment is slightly lower, and the steam turns into condensate. Due to this effect, ready-made coffee drips into the coffee pot.

The principle of the device can be found on the video presented.

Some models of drip coffee makers are equipped with auto heating function. Thus, the brewed coffee will remain hot for a long time.

Filtration methods

There are several ways to filter coffee. The first is carried out using a filter that is located in the machine itselfthat allows you to automate the process of brewing. The best are filters made of plastic. They have a long service life and do not require special care. There are also filters made from paper. Their advantage is that they are disposable - after use they are simply discarded. For the laziest, manufacturers have developed metal filters. It does not require replacement, but is not included in the basic package and requires additional financial investments.

The second method is filters that fixed in a cup or another container, where they pour the finished drink from the coffee pot. You can use both filtering methods at the same time.

Beverage level

Drip-type coffee maker works in such a way that you can choose for yourself the strength of the drink.

The strength of water through coffee beans, that is, the power of the machine, affects the strength of coffee.

The slower the speed and the lower the power, the more coffee substances the water manages to absorb. As a result, it turns out strong and juicy drink. The higher the speed and the stronger the power, the faster the coffee is prepared, but it will be less saturated.

Steam is produced when the water temperature reaches 100 degrees Celsius. During steam condensation in the brewing unit, the temperature decreases. The ideal temperature in this compartment should range from 86 to 95 degrees. In this case, the drink is obtained saturated and fragrant. Also, this temperature is perfect to use ready-made drink for the preparation of American, cappuccino or latte.

Criteria for choosing a coffee maker

Coffee makers offer several options for drip coffee makers. The devices are made of glass, ordinary metal or metal with thermal insulation:

1. The coffee pot, made of glass, easy to use. You can always control the level of filling it with water. But such a device is easy to beat, which can cause some discomfort.
2. Metal coffee pots maintain the temperature of coffee for quite a long time, but they are harder to track the amount of drink. At the same time, they are a bit more expensive than glass models.
3. If the model of your coffee maker does not support the function of selecting a fortress, and you are a fan of strong coffee, then you should buy an appliance with low power.
4. Thanks to a special indicator, you can always make sure that the coffee maker is working or not.
5. Absolutely all models are equipped with a function of temporarily stopping the beverage. You can pull out the pot, pour yourself a cup of coffee and put it back so that the machine continues its work. The function is valid for 2 minutes, provided that you have interrupted the operation of the device.
6. For the scattered and forgetful, there are coffee makers with automatic shutdown.Depending on the model, after a certain amount of time, the machine switches off the operating heating mode and thereby prevents the apparatus from overheating.
7. Design solutions of drip coffee makers are different - you can choose a model to your taste in any style, color scheme and design.
8. For fans of the American drip-type coffee maker - a real salvation. Ready drink you just need to dilute with milk, and American is ready!

Conclusion

The drip type coffee machine is convenient to use both at home and in the office. It does not require special skills for brewing a drink. When using the device, do not forget to rinse the filter thoroughly if it is not disposable. If you use disposable paper filters, change them in a timely manner. The taste of coffee prepared in a drip type machine depends directly on which filter is installed.
