Analysis on the working principle of Coffee Machine

Most people love coffee and can't have breakfast without an old friend-this is the coffee machine! Every morning, you scoop coffee into the coffee maker, add water, and turn on the switch, but have you ever wondered what's going on in there? How did the water flow out of the small compartment, where you poured it on top of the coffee machine, and what was the cooing sound?

Friends who like to drink coffee know that there are two kinds of coffee machines commonly used in families, one is the American coffee maker, also known as the American coffee maker, and the other is the high-pressure steam coffee machine. Here is a brief description of how these two coffee machines work:

1. Working principle of drip coffee machine

When the power is turned on and the switch is turned on, the indicator light is on and the heating tube starts to work. When there is no water in the tank, the temperature rises. When the temperature rises to a certain temperature, the thermostat is disconnected and the heating tube stops working. When the temperature begins to drop, the thermostat is restored and the heating tube continues to work to achieve heat preservation.

2. Working principle of high pressure steam coffee machine

The coffee pot has a high-pressure chamber, and when the water begins to produce a large amount of steam, the pressure in the high-pressure chamber is greater than the atmospheric pressure, so the water rises along the pipe and flows into the coffee filter under the action of steam pressure in the chamber. the coffee seeping from the bottom flows into the coffee cup. There is a safety valve at the top of the high pressure chamber (to ensure safety). Or open the air valve, you can use steam to bubble the milk.

The built-in closed small boiler water tank of this kind of coffee pot mainly relies on the steam produced by water at high temperature to produce coffee. The coffee produced by this kind of product has a stronger flavor than the drip coffee pot and is more suitable for people with higher requirements for coffee taste. This kind of goods generally have the function of beating fresh milk, and you can make "cappuccino" by yourself.
