What is the reason why the espresso machine's steam is getting weaker and weaker? What should I do if the steam is blocked? How to clean the coffee machine?

As we all know, the steam of the coffee machine is mainly used to heat the milk and beat the foam. The strength of the steam will determine the length of time to pass away the foam. The stronger the steam, the faster the milk will heat up, and the killing time will be greatly shortened, and vice versa. But recently, many friends have found that the steam intensity of the coffee machine at home is decreasing day by day, weakening every other day, because they spend more time with foam every day. This is a serious problem, so they went to Qianjie for consultation.

Some friends may think that even if the time is increased, as long as the milk can be heated and the foam can be dispelled, it should not be too much of a problem. But in fact, it is difficult to get a picture of the milk foam that has been sent for too long, because the milk foam that was first made has reached its limit and begins to break one after another. Then, this will make the milk foam appear mushy when drawing flowers, the stripes are not clear and blurred. Therefore, we need to find out the problem and solve it.

Why is the steam getting weaker and weaker? If you don't hear the sound of steam escaping from the coffee machine when you're not using it, nine times out of ten the problem lies with the sprinkler of the steam stick. The front end of the steam rod sprinkler usually has several small holes, which will be distributed in different directions of the sprinkler, and the main function is to emit water vapor.

Taking apart the sprinkler, we can see that there is a white pipe like a straw from which steam is transported.

Because the number of holes in the sprinkler is small and small, the amount of steam that can pass through is limited. But because the coffee machine is still pumping water vapor, the steam gathered together forms a powerful thrust, forcing the steam to be "pushed" out very quickly. Only by this kind of steam can the milk form a whirlpool and the big bubbles will be cut into countless small bubbles, delicate and silky. Therefore, we can know that the hole of the sprinkler is very important. When we found that the steam emitted by the steam stick of the coffee machine became weaker without failure, it meant that the small hole in the sprinkler was blocked. Because of the blockage, the steam becomes smaller. The reason for the blockage, the main culprit is that after dishing out the milk, the remaining milk dirt has not been cleaned up.

As we all know, milk is very rich in substances. after we dispose of the milk, if the milk left on the steam stick is not cleaned up, then the milk will be evaporated because of the high temperature of the sprinkler. The remaining substances that can not be evaporated will be attached to the steam stick, forming the milk dirt that we can see. Because the milk dirt exists in solid form, when it appears in the hole of the steam bar, it will cause blockage, because the outlet is limited, so the steam can not be discharged quickly, and then the strength of the steam is weakened. In a case like this, we need to dredge the holes in the sprinkler in order to restore the strength of the steam. As for dredging, we have a total of two steps. The first step is to poke out the milk dirt that clogs the hole with a needle-like sharp object. Because it can block the sprinkler, it shows that it has accumulated a certain thickness, if it is not dredged first, then the latter step will not be able to make a good effect.

When we use sharp objects to remove milk dirt from the passage, take out our washing machine baking powder, scoop a small spoonful into a prepared glass, then pour in the right amount of hot water and soak the sprinkler side in it for several hours. One night is fine.

When the soaking is finished, we take out the wash and put it back on the steam bar of the coffee machine, so that the cleaning of the sprinkler is complete! The steam can be restored to its original intensity. This kind of cleaning is more tedious, so we don't need to deal with it every day, just clean it every other week. However, when we use the coffee machine, we should not forget the daily cleaning. Every time we dispose of the foam, we need to use empty spray to remove the foreign body in the sprinkler.

In addition, after use, it should be wiped in time to prevent the formation of milk scale. As long as it is cleaned properly, then the sprinkler will not be clogged so easily.
