Many people like to drink coffee, especially those who are busy at work. Everyone knows that coffee has a refreshing effect, but in fact, coffee not only refreshes and reduces the radiation of the surrounding environment, but also prevents stones and cancer, protects the liver, nourishes the stomach and helps digestion. Therefore, whether in the office or at home, drinking a cup of coffee is very good for your health. The following is the knowledge I brought to you about how to use the coffee machine correctly. Welcome to reading.
1. What is the best brand of coffee machine?
After coffee became a common drink in OL, coffee machine became a necessary household appliance. So what brand of coffee machine is better? The better brands of coffee machines in the market are Philips, Electrolux, Kun Can, Braun, Delong, Swiss Coffee Man, Panasonic, Jiahui, SKG and Yourui.
Second, how to use the coffee machine
Although they are all brewed by coffee machine, the different types of machines will affect the way hot water contacts coffee powder. Of course, the matters needing attention when brewing coffee are different. Therefore, before buying a coffee machine, you'd better try it out. If you can't try it out, you can also consult relevant information online before buying.
1, control variable
When using coffee machine to brew coffee, the water temperature is mostly high. Because it is impossible to control the water temperature and the way of hot water injection, it needs to be adjusted by the amount of raw materials, coffee powder and the size of grinding particles. If you think coffee tastes heavy, you can try to choose coffee beans with low roasting degree or coffee powder with large particles.
2. About heat preservation
When we use the coffee machine, the metropolis turns on the heat preservation function, but if you pay attention to the taste of coffee, I suggest you cancel the heat preservation function. The aroma of coffee contains many volatile components. If stored at high temperature for a long time, it will promote the change of composition. If you keep the coffee machine warm for 10 minutes, you can easily detect the change of bitterness, acidity and aroma of coffee. There is a thermos bottle on the market that does not need to be heated. Although the taste will be lost compared with the freshly brewed coffee, if it is necessary to keep warm, it is better to choose a thermos with a smaller heat load.
Third, the classification of coffee machines
1, automatic coffee machine
The operation of the automatic coffee machine is very simple. First, we need to turn on the power first. The power supply that the coffee machine must connect is the power supply of the A/C socket, and then turn on the power supply; Secondly, put the coffee beans into the coffee machine bean box, which is almost 80% full; Then, take away the water tank of the coffee machine, fill the water tank with almost three quarters of water, put the water tank back into the machine, cover the water tank, and make coffee after the preparation is completed. Some coffee machines are equipped with powder slot buttons, while others are not. The specific buttons vary from coffee machine to coffee machine.
2, semi-automatic coffee machine
Before using the semi-automatic coffee machine, you need to grind the coffee beans into powder, then put the coffee powder into the handle groove, but don't fill the handle groove, just fill it about two-thirds, and then flatten the coffee powder with a powder pressing tool. When the coffee powder is flattened, you can use the semi-automatic coffee machine. Turn on the power first, then aim the pressed coffee powder at the mouth of the coffee machine at a 45-degree angle and rotate it to the right until the cover is tight. Finally, you just need to put the coffee in the cup.
3. Trickle filter coffee machine
Before using drip coffee, you need to preheat the coffee pot, then add a filter paper to the funnel of the coffee machine, and put 7 to 9 grams of coffee powder in each cup. Close the funnel door, add 175 ml water to the tank, and turn on the power supply. After the boiling process is completed, when the glass pot is taken out, the coffee machine will automatically turn on the drip prevention function.
4, high pressure steam coffee machine
As the name implies, the high-pressure steam coffee machine is a combination of pumping and steam. The drip coffee maker mentioned above uses one atmospheric pressure when making coffee, that is, at normal pressure, while the pump coffee maker uses the pressure principle. When brewing coffee, the pressure of water is greater than one atmosphere, generally 5- 19 atmosphere, and the coffee essence is quickly extracted. The brewed coffee is very fragrant and has a layer of grease foam.
Fourth, how to clean the coffee machine
Tools required:
1. coffee machine cleaning powder;
2. backwashing dishes;
3. Long handle coffee machine cleaning brush.
Cleaning steps
1. Take out the metal coffee filter in the handle of the coffee machine, and then put the blind bowl (anti-cleaning dishes) into the coffee handle. If you don't have a blind bowl, you must have a rubber blind pad when you buy a coffee machine, or put the rubber blind pad directly into the metal coffee filter, and remember that there is an obvious convex side up.
2. If it is cleaned every day, take 1 tablespoon of cleaning powder; If you don't clean it often, take 2 spoonfuls and put them in a blind bowl or rubber blind pad.
3. Don't press the handle of the coffee machine in a hurry, press the brewing button of the coffee machine, and brush the water distribution net with the cleaning brush of the coffee machine when the brewing head works. The reason for this is to prevent excessive superfine coffee powder from entering the coffee machine in the subsequent backwashing process. Brush the water without coffee grounds and you can turn off the brewing button.
4. Tighten the handle, press the brewing button of the coffee machine, run for about 10 second, and then turn it off for 10 second, so that the detergent can be fully dissolved. Opening 10 second, closing 10 second, once; After repeating it for 4-5 times, turn off the coffee brewing button.
5. Take off the handle, clean it, plug it into the coffee machine again, press the brewing button of the coffee machine, run for 5 seconds, turn it off for 2 seconds, and repeat 7- 10 times to ensure complete cleaning.
6. Remove the handle and rinse the inner groove of the cooking head again with a cleaning brush to avoid residual coffee grounds and cleaning powder.
Suggestion: In order to ensure the quality of coffee machine and the original flavor of coffee, it is recommended to clean it once a day, make a cup of espresso after cleaning, and clean all the residue.
The purpose of cleaning
Understand the cleaning process, and then talk about why we need to clean. Coffee will secrete oil, which will condense on the internal parts of the coffee machine; After a long time, the oil will be burnt by high temperature, which will bring strange bitterness and sour taste to coffee. You can't cook in a dirty pot, let alone make coffee in a dirty coffee machine. This is a truth!
Clean up not only the surface we see, but also the inside!
How to replace the sealing ring of semi-automatic coffee machine?
Continue to explain how to replace the sealing apron around the brewing head. Be sure to look carefully, because it will save you money! Save money! ! Save money! ! !
What is a sealed apron?
When making coffee, there is a rubber ring between the coffee handle and the brewing head. This is the sealing apron, which is a key accessory to ensure the extraction pressure and water leakage!
When to replace the sealing ring?
As shown in the above figure, the edge of the handle leaks during production; Or when the coffee handle needs to be stuck with great force, the sealing ring needs to be replaced!
Why do you want to change it?
The sealing apron of coffee machine will age much faster than the apron at room temperature when it is at high temperature for a long time, and it usually needs to be replaced once every six months. After aging, the apron will lose its elasticity and break, resulting in insufficient pressure on the handle. When extracting, the edge of the handle leaks, and espresso will naturally be mixed with water and coffee grounds.
Tool for replacing sealing apron
Brand new original sealed apron
Flat head screwdriver
Cleaning brush for coffee machine
That's it, it's simple! ! !
Replacement steps
1. Turn off the coffee machine and let it cool. Why? I'm afraid you'll burn your hand. If you think you can use tools or your hands can withstand high temperatures, you can ignore this step.
2. Hold the water distribution pipe network with a screwdriver and pry it down gently. If you feel that the water distribution network card is tight, you can find a few points and try to pry it down! Don't worry! Be sure to gently!
Step 3 take off the apron
This apron is ok, many machines have entered carbonization, and even the shape is gone when they are taken off.
This is what is in the water distribution network! This is the water separator, which should be washed every night when backwashing.
4. Use a cleaning brush to clean the groove of the rubber ring! Then we put on a new apron, and remember that the marked side of the sealing apron is facing up. Press it back into the groove of the sealing rubber ring, then clamp the coffee handle on the brewing head normally, and push the sealing ring back by connecting the handle with the brewing head!
Remember when we started talking about saving money? Generally, we change an apron ourselves, which is only 20~50 yuan. But you need to find a professional coffee repairman to replace the sealed apron, which is basically between 200 and 300. And replacing the sealed apron should be regarded as the basic skill of the barista!
