How is “capsule coffee” produced and how is it kept fresh?
The production of capsule coffee is actually not a mystery. If we cut open the capsule, we find that there is nothing more than coffee powder inside.
Let’s take a look at anatomy:
In fact, the structure of this type of capsule is very simple, that is, the ground coffee powder is stored in the capsule. Because the space in the coffee capsule is also limited, there is not much preservation technology, and it is impossible to fill with nitrogen in such a full space. These steps, as long as we ensure that our capsules are sealed, the basic freshness can be basically achieved.
We can take a look at what the capsule production line looks like and what kind of process it looks like:
1. Raw beans, roasted mature beans
2. Grind cooked beans into coffee powder
3. Filling
The machine arranges the capsule shells and fills in the coffee powder
4. Sealing
Cover the capsule, heat and seal
5. Packaging
Put it in a box or bag
The above is just the process of a factory, all the processes are similar, the machinery and equipment look a bit different.
According to the information I have read so far, the preservation of capsule coffee is one point: sealed, coffee beans are most afraid of oxidation, oxidation will give our coffee a bad taste, and make the coffee powder stale, only completely sealed In order to keep as fresh as possible
In addition to this very common capsule on the market, there are also such as tassimo
The capsule structure is slightly different, but the preservation is still the same mainly by preventing oxidation
