How do coffee pod machines work pros and cons

Coffee Pod Machines Explained

If you have never used coffee pod machines more than likely you probably don’t even know how these pod machines work. Well, the basic principle is pretty much the same with all the various pod machines that are available on the market today so you pretty much get the same cup of coffee from each of them such as K-Cup, Tassimo, Nespresso, Senseo and Dolce-Gusto. What happens with each of these pod machines is that you start off with what they call a pod which has ground coffee inside of it’s plastic container that is lined with a filter paper and then is sealed in foil. You take the pods and put them in the pod machines which in turn will break through the foil automatically. The pod machines will then heat the water to near boiling and they force the water at extremely high pressure through the coffee that is in the pod into your single serving cup. Pretty much like a traditional espresso machine would do.

Pod Machines basic operation goes pretty much like this:

  1. Load the water into the tank that is at the back of the pod machines.
  2. Then a pump at the bottom of these pod machines will suck the water in and then pumps it through the pod machines.
  3. After that is done the water will be heated up to the ideal temperature as it flows up through the heating element.
  4. Next the water is pumped through a narrow needle that helps to increase the needed pressure for these pod machines.
  5. Once the pressure needed is achieved for the pod machines the hot and high pressure water pumps through the ground coffee found in the pods and it releases the flavor of the coffee. With the Tassimo pod machine you will find that the water pumps up and then into the pod through a little narrow hole at the edge and then it drips back down again through a much bigger hole found in the middle.
  6. The filter paper in the pods at the bottom is what stops the grounds from falling out and getting into your cup of coffee.
  7. Finally, the coffee drips through to your coffee cup.

The water heater of these pod machines can heat enough water for a cup of coffee that can range for 70° F to 185° F in just under a minute so this is great speed for someone in a hurry and on the go. They have powerful pumps than can move nearly a liter of water in a minute and works at about one to two times faster than normal atmospheric pressure. This might sound like a lot of pressure coming from these pod machines but believe it or not it’s a lot less pressure than you find coming from your typical espresso machine that works around 8 to 15 times the normal atmospheric pressure.

The air compressors for all pod machines work after the coffee is dispensed by blowing pressurized air out through the machines and ensures that all the pipes of the machines are clear and ready to brew the next cup of coffee.


  • Coffee pod machines are extremely easy to use
  • Produce a decent cup of coffee
  • Quick and convenient and hassle free
  • No need to grind beans, tamp it down, no extraction and no worry about getting just the right water temperature


  • Range of coffees is limited
  • Lack of freshness since the coffee is not freshly ground and is pre-ground coffee stored in a plastic container
  • Limits ability to vary the parameters of your coffee making style due to total automation and no ability to program it the way you want. Cannot set to your own personal tastes
  • Not environmentally friendly. When you process coffee with pod machines you are wasting the plastic pod, the metal foil and filter paper each and every time you have a single cup of coffee brewed from one of these machines.
