Coffee machine Wikipedia-How to use a coffee machine

1 Introduction to coffee machines

Electronic technology has been applied to coffee machines to create automatic control of the entire process of brewing coffee, including grinding, pressing, loading, brewing, and removing residues, creating coffee machines. The coffee polished with a coffee machine can make people genuinely enjoy the aroma and taste of coffee, which is the original coffee.

2 How the coffee machine works1. Principle of operation of fully automatic coffee machines

The machine automatically grinds the beans, automatically presses the powder, and automatically brews the coffee; using the pressure of the water pump, the hot water in the fever boiler will instantly pass through the brewing cavity and compress the coffee powder, extracting the inner essence of the coffee immediately, so that the coffee has a strong aroma and forms a thick layer of exquisite foam on the surface.

2. Working principle of the semi-automatic coffee machine

The semi-automatic coffee machine has a high-pressure chamber. When the water starts to produce a large amount of steam that cannot be relieved through the small holes, the pressure in the high-pressure chamber is higher than the atmospheric pressure. Hence, the water rises the water pipe and flows into the coffee filter under the steam’s pressure produced in the chamber. The high-pressure chamber has a safety valve at the top (to ensure safety). Alternatively, the bleeder valve can be opened to apply steam to froth the milk.

3… Drip coffee machine working principle

When the power is turned on, and the switch is switched on, the indicator lights up, and the heating element starts to work. When there is no water in the tank, the temperature rises, and when it reaches a specific temperature, the thermostat is switched off, and the heating element stops working. When the temperature starts to decrease, the thermostat is restored, and the heating pipe continues to work, thus achieving heat preservation.

4. Working principle of high-pressure steam coffee machines

The coffee pot has a high-pressure chamber. When the water starts to produce a large amount of steam, it cannot escape through the small holes, so that the pressure in the high-pressure chamber is higher than the atmospheric pressure. The high-pressure chamber has a safety valve at the top (to ensure safety). Alternatively, the steam can be used to froth the milk by opening the bleeder valve.

3 Types of coffee machines1. Fully automatic coffee machines

The automatic coffee machine is a fully automatic coffee brewing machine that eliminates the need for hand operation. Such coffee machines can grind, fill, and produce coffee, and some can even add hot milk and make milk coffee. Fully automatic coffee machines are involved, but convenient, fast, consistent, efficient, and come in a wide variety, but require good maintenance and are expensive to maintain. The famous coffee packet and capsule coffee machines can also be called fully automatic machines. However, the difference between these two and traditional coffee machines is that the raw materials used are coffee bags and coffee capsules, such as coffee semi-finished products rather than coffee beans.

2. Semi-automatic coffee makers

It consists of a funnel that holds the filter paper and coffee powder, with an essential coffee filter. A V-shaped funnel on the top and a removable coffee pot on the bottom is the classic style of a drip coffee machine.

4. High-pressure steam coffee makers

As the name implies, high-pressure steam coffee machines are a combination of pump pressure and steam. The drip above the coffee machine uses one atmospheric pressure when brewing coffee, brewed at atmospheric pressure. In contrast, the pump pressure coffee machine is through the principle of force, brewing coffee when the water pressure is more significant than one atmospheric pressure. Generally 5-19 atmospheres, rapid extraction of coffee extracts, the coffee brewed out of a more potent aroma, and a layer of oil foam.

4 How to use a coffee machine

When using a coffee machine to make coffee, the general steps are.

1. Choose coffee powder; if it is coffee beans, you need to grind the coffee beans now to produce coffee.
2. in the use of filter paper, is to unfold the filter paper to form a funnel’s shape, the user can according to their own needs in the appropriate amount of coffee powder into the filter paper. The primary purpose of using filter paper is to filter out impurities and increase the coffee’s aroma while also being easier to clean.
3. Put the coffee into the basket with the filter paper.
4. Use the coffee maker to fill it with a small amount of cold water.
5. Put the water from the coffee maker into the water reservoir at the back of the coffee maker.
6. Put the lid of the coffee maker on the coffee maker and switch it on.
7. After the coffee is made, the coffee maker will automatically stop boiling water and keep the coffee warm.
8. Finally, take out the filter paper and clean the filter paper basket to complete coffee production.

Flatten the coffee powder with the tool used to press the powder. Once the coffee powder is flattened, you can use the semi-automatic coffee maker.

Turn the power on and then rotate the pressed coffee powder at a 45-degree angle to the right of the machine’s mouth until the lid is tightly closed. Finally, you will only need to fill the cup with coffee.

How to use a drip coffee maker

1. when using the drip coffee machine to make coffee need to preheat the coffee machine, and then add half a pot of water in the water tank of the coffee machine, and at the same time turn on the power of the coffee machine.

3. Use filtered water to brew the coffee, which will produce a perfect cup of coffee.

High-pressure steam coffee machines

To make coffee, you must first connect to the power supply, and the high-pressure steam coffee machine must be connected to an A/C socket. The voltage used must be under the voltage specified on the packaging of the device. Remove the bean box’s lid and put a suitable amount of coffee beans into the bean box (most fully automatic coffee machines have a bean box capacity of no more than 400G), and fill it to 80% full.

1. Take off the water tank on the machine, remove the water tank cover and fill it with about 3/4 of the freshwater capacity; the valve at the bottom of the water tank acts as a drain. When putting the water tank back into the machine, gently press the water tank against the valve that opens automatically and close the water tank lid.
