How Does a Traditional Coffee Machine Actually Work?

When you press a button on a traditional coffee machine, it can look deceptively simple. Within seconds, the machine has taken stored ingredients, combined them with hot water and produced a consistent cup of coffee.

So, how does it actually work?

What is a traditional coffee machine?

Unlike a bean-to-cup machine, a traditional coffee machine doesn't grind coffee beans for every drink.

Instead, it uses pre-prepared soluble coffee. The coffee has already been brewed and processed into a dry form that quickly dissolves in hot water.

This means the machine doesn't need a grinder, brewing group or the same mechanical process required by a bean-to-cup machine.

What happens when you select a coffee?

The process is surprisingly straightforward.

1. You select your drink

The machine's controls tell it which drink you've chosen and how much of each ingredient is required.

2. The machine dispenses the ingredients

The machine accurately dispenses the required amount of coffee, along with other ingredients where applicable, such as milk or chocolate.

3. Hot water is added

The machine heats water to the required temperature and delivers it into the mixing system.

4. Everything is mixed

The ingredients dissolve into the hot water, creating the finished drink.

5. Your coffee is dispensed

The finished drink is delivered directly into your cup — usually within 10 seconds.

Why use traditional coffee technology?

The biggest advantage is speed and simplicity.

Because the coffee has already been processed, the machine doesn't need to grind and brew beans for every cup.

That makes traditional machines particularly useful in environments where lots of people need drinks quickly — such as trade counters, warehouses, factories and busy workplaces.

There is also less mechanical equipment involved, which can make the machines straightforward to operate and maintain.
