Take care of your coffee machine-what water does your coffee machine drink?

Recently, Beijing stopped central heating, and the temperature in the house dropped obviously. Yesterday, the coffee machine was turned on frequently and started almost every minute. It may be because the room is too cold to maintain the temperature of the coffee machine, but I am not sure. Just for this reason, turn on the coffee machine and check the recent water quality.

[Giotto opened the top cover of the machine and saw various valves and probes on the boiler]

[carefully unscrew the water level probe nut on the red line and pull the water level probe out of the boiler]

[with the help of a flashlight, the water in the boiler can be seen through this hole]

[after pulling out the probe, there is no scale on the probe, indicating that there will not be too much scale in the boiler]

Through this verification, it is at least proved that the frequent heating is not due to the low heating efficiency caused by too thick scaling in the boiler. After burning the coffee machine for a period of time, touch the fuselage, it is already hot, at this time, the heating frequency is obviously less, it seems that the environment really affected the work of the coffee machine.

Although, my machine is "healthy", what about yours? If you have a bar in your home or store, I think the coffee machine will be the pillar or core of the bar, then you need to take care of him. Only by taking good care of him will he be willing to work for you. Isn't it true that scale is fatal to your machine, especially the water quality in northern China, which is mostly hard and easy to form scale, so effectively reducing the production of scale will be the greatest protection for your coffee machine.

Let's take a look at the coffee machine that is not properly protected. (the following pictures are borrowed from the Internet)

[for a machine that has been used for a long time and is not maintained, when the boiler probe is taken out, the probe is already covered with scale. How can you expect such a probe to work normally?]

[thick scale condensed on the probe]

All the probes are like this, so you can imagine the heating elements in the boiler.

It is important to prevent scale effectively and clean it regularly, but choosing an appropriate water source makes it difficult or less to produce scale, which is a more active method. The main cause of scale is that calcium and magnesium ions in water form a relatively stable calcareous structure under thermal conditions, which is wrapped on the heating element so as to reduce the heating efficiency of the heating element.

At present, the main solution is to use the method of softening water, mainly in the following ways:

Method

Advantages

Shortcoming

1. Resin water softener

1. Easy to install

2. The initial installation price is relatively low (800-1300 yuan)

3. The maintenance price is low

3. The coffee machine can use the water source of the pipe, and there is natural pressure in the pipe.

1. The effect of softening water is not very thorough

2. Only soft water can be used. If the water is not purified, the water source is still not drinkable directly.

2. Water purification system

1. Besides soft water, it can also purify the source of water, ensure the quality of drinking water, and improve the quality of brewed coffee.

1. The price is relatively high and the overall cost is also high.

2. Installation is relatively complex

3. Reverse osmosis membrane pure water machine

1. Be able to produce pure water to ensure the quality of water.

1. The price is relatively expensive

2. The process efficiency of reverse osmosis membrane is relatively low, and the speed of water production is slow.

3. The coffee machine can not be directly connected to the water source (the final pressure caused by the inefficient production is not enough to guarantee the water supply of the coffee machine)

4. Only pure water can be picked up for the coffee machine, and the water source has no pressure to cause additional burden on the coffee machine water pump.

4. Barreled pure water

1. Very simple and easy to operate

2. Water quality is guaranteed.

1. Long-term use is expensive

2. The barreled water source can not provide water pressure for the coffee machine, which will put an additional burden on the coffee machine water pump.

The above methods are effective methods to improve the quality of water on the market at present, it can be said that each has its own advantages and disadvantages, or need to be compared by all users, according to their own situation and conditions to decide. Because I am using it at home, the production quantity is not large, so I choose to use the reverse osmosis membrane pure water machine to connect the water to a large bucket for my coffee machine to use. the biggest disadvantage of this method is that the water source has no water pressure. in this way, the effect of pre-infiltration of E61 is the same as that of E61 (the pre-infiltration of E61 head depends on the pressure of the water source itself. If you are connected to tap water, there is water flowing out when you half-open the head. But with bucket water, there is no more.

Get your coffee maker and find a suitable source of water.

In addition to the scale, daily cleaning of the water distribution network on the head is also very important. Look at the picture below.

It is also very important to clean your head after each use, do recoil, check the head regularly, and clean the gap between the water diversion network and the outlet, otherwise your head will probably be like the picture above for a long time. There is a lot of coffee adulteration between the outlet and the water distribution network, so it is conceivable that what you drink every day is completely filtered coffee.
