An espresso coffee machine is used to brew espresso and espresso-based drinks. The working mechanism involves high pressure that forces water through a puck of ground coffee and a filter to brew a perfect concentrated shot of espresso. There are many kinds of espresso machines designed and each of them has different features and functions. A good espresso machine is always in demand for every coffee lover.
The home espresso machines are designed differently according to the requirements like a small capacity water tank, compact body, etc. Likewise, commercial espresso machines are designed differently they have high-capacity water tanks, more durable bodies, etc. Not just the designing the working mechanism also differs in different types of espresso machines.
For example, the working mechanism of manual espresso machines and automatic espresso machines is different. We will help you to learn about the working mechanism of different types of espresso machines.
Working Mechanism of Manual Espresso Coffee Machine
Traditionally, the manual espresso machine was also known as a lever machine. Because it uses a lever instead of a pump to create pressure. The mechanism involves pulling the lever to force the water through the coffee grounds.
Using this manual espresso coffee machine you can create smoother espresso. Let us learn the working mechanism of a manual espresso coffee machine using a Profitech Pro 800 manual espresso coffee machine.
This espresso machine has a single boiler system. Now how does exactly the espresso machine brew espresso?
The way this works is as the water leaves the steam boiler and goes through the pathway to the group head in between it rapidly loses heat. This water delivery mechanism is known as a dipper. This is how the 250 Fahrenheit water cools down to make a cup of coffee. Now the next question is what does the lever do? The lever is connected to a spring in the group head.
As we pull down the lever the spring in the group head will be compressed and the water will be pushed out of the boiler by the dipper. Measure the required amount of coffee for a shot of espresso then put a cup under the group head pull the lever at the bottom and hold for 6 seconds and the espresso starts dripping into the cup. And the perfect shot of espresso is ready.

The cleaning and maintenance of the automatic espresso machines are super easy.
These machines are accessible to all you do not require much skills for operating an automatic espresso machine. Let us learn about the working mechanism of an automatic espresso machine.
An automatic espresso machine uses a boiler to heat the water. The thermostat and temperature sensor are the features of this machine that regulate the temperature and level of water required for a cup of coffee.
A pump is one of the components of this machine which provides high pressure to force the water through a puck of ground coffee. The valves control the water flow to maintain the consistency. Many automatic espresso machines come with a built-in grinder that grinds the coffee beans into fine grind size.
The machine measures the amount of coffee required for a single shot and compresses the coffee evenly into a portafilter. The pump forces the water through the ground coffee and the process of extraction starts from the group head. Put a cup below the group head and a perfect cup of espresso is ready.
