With the widespread popularity of boutique coffee culture, more and more coffee lovers begin to buy coffee equipment, coffee utensils and coffee beans online, and learn how to make a cup of coffee to their satisfaction.

In recent years, the coffee equipment market has also launched a variety of espresso machines suitable for family use, so many coffee lovers will buy an espresso machine at home.

Due to the lack of in-depth understanding of the Italian coffee machine, there are many small partners who do not do timely cleaning and regular deep cleaning after use, resulting in a variety of minor problems after using the coffee machine for a period of time.

For example, the steam becomes smaller, the water falling from the cooking head is uneven, and the leaking occurs in the process of extraction after the handle is fastened. What should we do when we encounter these situations? How to maintain the espresso machine on a daily basis?

"Daily cleaning of household coffee machines"

At present, Qianjie stores use an Italian coffee machine suitable for household use as well as for community / small coffee shops. In general, the coffee used in the family is easier to clean because it is not used frequently. However, we also need to pay attention to the casual cleaning after use, as well as the regular cleaning of parts.

Daily cleaning refers to the cleaning steps that we need to do after the coffee is made. It is usually necessary to pay attention to two parts: the timely cleaning of the steam rod and the timely cleaning of the water distribution network of the cooking head.

1. Timely cleaning of steam rods

After heating the foam, a thin layer of foam remains on the steam stick. If the steam bar is not cleaned in time, the high temperature of the steam bar will cause the foam to stick to the steam bar and gradually coking, which will not only deteriorate and produce peculiar smell over a long time, but also block the hole of the steam, resulting in a smaller steam out of the steam bar in the later stage.

Therefore, each time you finish making the foam, you need to wipe the remaining foam with a clean wet dishcloth immediately, and put the steam stick head above the water barrier (not in the direction of anyone), and then turn on the steam to spray again. The aim is to spray the milk that may be left inside the steam outlet.

two。 Timely cleaning of the water distribution network of the cooking head

The watershed is the net part of the head, which is the part that comes into direct contact with the coffee powder every time you brew the coffee. Because the coffee powder is pressed, the coffee liquid can seep out of the powder bowl only when the pressure reaches a certain range, so it is still possible for the coffee liquid to flow back before it seeps out. Even if the coffee seeps out, some coffee oil and powder may remain in the water distribution network.

If it is not clean for a long time, a large amount of residue and grease will be left in the water distribution network and pipes, thus affecting the taste of coffee brewing.

Therefore, after each extraction of espresso, remember to clean up the coffee pressed powder in the powder bowl, and the coffee residue attached to the water diversion network can be washed away by pressing the water release button of the brewing head, or you can use a cleaning brush to clean up the coffee residue attached to the water distribution network.

"cleaning before the coffee machine is turned off."

Generally speaking, if it is a coffee machine used at home, because the frequency of use is not high, it is not necessary to often use special powder for cleaning. However, you still need to use the blind bowl of the coffee machine (a powder bowl without a water hole) for recoil, use the pressure generated by the coffee machine itself, let the hot water wash the boiling head constantly, and because the water cannot flow out, thus sucking back into the pipe to clean the coffee residue and releasing it.

After the recoil is complete, remove the handle of the blind bowl, and then turn on the switch to let the water flow out of the head. Use a brush to clean the residual coffee powder / coffee stains in the grooves of the head (use a little force when brushing and pay attention to the emergence of hot water). Finally, wipe the whole coffee machine with a clean cloth.

After turning off the power supply, we also need to turn on the steam bar switch to discharge the remaining steam to avoid the occurrence of scale caused by steam water remaining in the pipe for a long time. Finally, pour out the coffee water part of the coffee machine, then wash and dry.

"regular deep cleaning of coffee machine parts"

Even if the coffee is cleaned in time after each coffee is made, and before the machine is turned off, it is difficult to avoid coffee stains remaining in the interior of the water distribution network for a long time, and milk stains will more or less block the vents.

1. Deep cleaning of steam rods

There are two cases in which steam holes are blocked, one is blocked by scale, the other is blocked by milk stains. In general, the head of the steam rod can be removed, if not, we will soak the whole steam rod and clean it.

For the former, we need to dilute and soak with special scale cleaning powder according to the proportion. The latter can be soaked in hot water, then dredged with a special steam hole cleaning brush / SIM needle, and finally put the steam rod above the water partition area, and then turn on the steam again for empty spray to observe whether the outgassing state is restored.

If there is no recovery, and it is certain that the hole is not blocked, you need to contact the coffee machine after-sales / maintenance operator for maintenance.

two。 Deep cleaning of water diversion network

Although we often clean the water diversion network, but the water diversion network is a bowl-shaped part, we only brush the bottom of the water diversion network, the interior can not be brushed. However, if the disassembly of the water diversion network is often carried out, it is also easy to lead to the deformation of the water diversion network. So we need to prepare special coffee machine cleaning powder (sold separately on the Internet).

Then operate like a daily recoil, but with one more step of adding powder. First of all, let's remove the powder bowl from the cooking handle, press the blind bowl, and put about 3G coffee machine cleaning powder on the blind bowl.

Then buckle the cooking handle and press the extraction key. Due to the resistance of the blind bowl, the coffee machine will relieve the pressure during the pressure extraction, thus "sucking" the cleaning powder into the pressure relief pipe to play a cleaning role. The recoil time with cleaning powder should not be too long, each time about 15 seconds, continuous operation 3-5 times, the reason is that the pressure relief valve working for a long time may have the risk of damage.

After backflushing 5 times, pull out the coffee handle and you can see the water with coffee dirt and foam in the blind bowl. At this time, you need to press the extraction button, first discharge part of the sewage with coffee cleaning powder, and then use a cleaning brush to clean the cooking head and water distribution network.

3. Deep cleaning of powder bowl with handle

If you use a brewing handle with a shunt nozzle, there will be a lot of coffee leftovers and grease in it, which will stink if you don't clean it for a long time. Therefore, it is necessary to prepare a pot of boiling hot water, pour in some coffee machine cleaning powder, stir well, put the brewing handle and coffee powder bowl into the basin and soak for 30 minutes. Then use clean water to wash off the sewage with cleaning powder.

"regular maintenance of coffee machine"

If there is a side leakage during the extraction of coffee, or when the handle cannot be fastened properly, it may be that the apron hardens. At this time, we need to buy a new apron to replace it.

The structure of the cooking head of each coffee machine will be different. How to disassemble the cooking head and take out the rubber ring? it is suggested that we should contact after-sale first and then disassemble it.

First of all, turn off the machine, and then remove the head after the coffee machine cools down (to avoid scalding). Then we can first soak the water distribution net to clean / clean water with a brush to wash the coffee stains in the clean net.

Then, after removing the aging apron, wipe the coffee residue of the boiled head with a clean cloth, and some may not be replaced in time because the apron is aged, leaving part of the carbonized apron residue.

Then put the new rubber ring on the water distribution net and install it on the cooking head together. The ways of changing aprons for different types of cooking heads will be different, so be sure to ask clearly before starting to operate after sale.

"about the water used in the coffee machine."

Filtered water is recommended for household espresso machines.

Unfiltered water / impurities, too much mineral water is easy to cause coffee machine boiler scale, light will affect the taste of coffee performance, serious will lead to lower boiler efficiency. If a large amount of scale is attached to the boiler, the cost of maintaining and cleaning the boiler is not a small expense.
