[Coffee Machine]Classification introduction of several common types of coffee machines and coffee pots
History of coffee pots:
One of the earliest inventions in Europe, the coffee pot was invented in France around 1685 and was widely circulated throughout the period of Louis XV. It’s nothing more than a carafe with a heated metal plate attached and an alcohol lamp underneath to heat it. Because this kind of coffee pot is very time-consuming, American Benjamin Thompson invented the Longford filter coffee pot, which was very popular at the time.
In 1763, the Frenchman Dunmardan invented the idea of putting the crushed coffee beans in a flannel bag, hanging it on the side of the pot, pouring hot water, and letting the coffee in the bag mix with the hot water. The water is heated for a long time, resulting in different brewing methods, which greatly improves the aroma of the coffee.
In 1800, the Archbishop of Paris, De Bello, invented a two-stage pot-type coffee heater, which was specially designed to keep the aroma of coffee from overflowing. originator. In this type of pot, the ground coffee is placed in a hole-like container on the top of the coffee pot, hot water is poured from it, and the water flows through the small holes of the container to the bottom of the coffee pot. It is characterized by the use of cold water for quenching, slowly absorbing the essence of the coffee drop by drop at a speed of 40 drops per minute. Since the speed is extremely slow, you should choose a very finely ground coffee for extraction. The coffee brewed by this method contains very low caffeine and tastes particularly refreshing.
In 1840, Nabel, a British marine engineer, invented the siphon coffee heater. This heater is designed based on the fact that when the water boils, the air pressure in the container containing the coffee powder decreases, so the boiling water is automatically absorbed into the coffee. And this is the predecessor of the Belgian Royal Coffee Pot.

Coffee maker introduction (representing different methods of brewing coffee):
Siphon coffee maker
The siphon coffee pot is also known as a plug pot or a vacuum pot. It is divided into upper and lower parts. It is made of glass. The water below is heated by an alcohol lamp or a gas lamp. The coffee beans should be ground into medium thickness and placed on the top. There is a cloth filter screen in the middle. After the water boils, the steam pressure forces the water to rise through the pipe. At this time, the coffee bean powder in the upper pot is in contact with the hot water, and the stirring action makes it mix like mud and dissolve out. Four flavors of coffee. After the coffee and water are fully soaked, the fire source is extinguished. After the air in the lower ball is cooled, a vacuum state will be formed, and the coffee liquid will be sucked back into the base through the filter cloth. At this time, pour the coffee into the preheated cup, namely You can indulge in its unique fragrance and taste its sweet and bitter taste. In recent years, the so-called ground coffee (Italian-style espresso) has become popular. In contrast, this siphon coffee pot requires higher technical skills and more complicated procedures. In today’s industrial and commercial society where every second counts, there is a gradual decline. But the aroma of coffee brewed by a siphon coffee maker is generally unmatched by ground coffee brewed by a machine.
When making coffee with a siphon coffee pot, pay attention to a few points: water quantity, water quality, heat, amount of coffee powder, thickness, stirring, time.
Step 1. Pour hot water to the bottom of the glass.
The amount of water to be added to the lower ball is 200ml when boiling one cup, 175ml when the bottom water is not poured, and 350ml when boiling two cups. After pouring the water, dry the glass ball with a rag, otherwise the glass will be easily broken.
Step 2. Put the filter into the upper ball.
Take the filter out of the water, wash it and press it dry, hook the hook of the filter to the bottom of the upper ball, and then use the adjusting stick to adjust the position of the filter to the middle position.
Step 3. After the water boils, insert the upper ball into the lower ball.
Turn to a small fire, carefully place the upper glass ball into the lower ball at an angle, make sure the water does not roll too much and spray out, press the upper glass ball straight down slightly and rotate at the same time That’s it.
Step 4. After the water has risen by half, add the coffee powder, start stirring, and start timing after stirring.
Pour 15 grams into each cup, and start stirring for the first time. Don’t make a circle when stirring, draw a three-quarter circle back and forth from left to right, and press the powder into it from top to bottom. In the water, make the forces of two different directions collide with each other, do not stir for too long, just let the coffee powder spread.
Step 5, do the second stirring at 25 seconds.
Step 6, stir for the third time at 55 seconds, and turn off the heat at 60 seconds.
It only takes 50 seconds to brew a single product coffee (the second time at 20 seconds, the third time at 45 seconds). The water is poured out, and the ball is inserted back into the ball. This action is called pouring the bottom of the water. If you do not want to do this step, the water only needs to be 175㏄.
Step 7. Immediately after turning off the fire, wipe the ball under the glass with a damp and cold towel.
Step 8. When the coffee liquid is filtered to the end, pull up the ball on the glass, do not let the last coffee flow down.
When using the siphon method to brew coffee, the cleaning and preservation of the filter cloth is quite troublesome. The completely removed fat and protein will produce an unpleasant odor in contact with the air, which seriously affects the delicious taste of coffee.
Royal Belgian Coffee Maker
It operates on the same principle as a siphon coffee, but it is very simple!
Step 1. Add the required amount of water to the metal pot, about 350CC for two people, and cover it tightly.
Step 2. Put the required coffee powder, about 30g for two people, into the glass pot at the other end.
Step 3. Lift up the metal pot, open the lid of the alcohol lamp, lock the lid of the alcohol lamp with the metal pot, and light the alcohol lamp.
Step 4. When the water is heated, the hot water flows into the glass pot with the siphon to contact the coffee powder. Once the water in the metal pot is less and less, the weight becomes lighter, and finally makes the alcohol lamp cover After the rebound cover is turned off, and the metal pot is no longer heated and cooled, the coffee is separated from the coffee grounds through the filter at one end of the siphon, and the water is slowly sucked back from the glass pot.
Mocha Coffee Maker
High pressure, italian style, originally referred to a high pressure and fast coffee brewing method, and later it was used in this way. Coffee brewed in this way is also called mocha coffee. When brewing coffee in this way, first grind the fine powder with the same particle size and compact it with the press. 8~9bar hot water pressure. Under strong pressure, the hot water finds a way to soak the coffee block. When the coffee block is tightly packed, each coffee bean powder can be extracted evenly by the hot water, and it is completely injected into the cup, and a small cup is instantly obtained. For a rich and aromatic espresso coffee, whether the pressure and resistance can achieve a balanced symmetry is an indispensable factor for brewing a cup of thick and delicious mocha coffee.
Since mocha coffee uses a pressure of 8 to 9 bar to force hot water to pass through the coffee powder quickly, the extraction time of each cup of coffee is only about 25 to 30 seconds, which saves a lot of time and cost. The time for the water to pass through the coffee grounds is very short, so the grinding scale needs to be fine and stable.
To get good grinding quality, a good grinder is indispensable, because only use a grinder that cuts beans quickly, the temperature rises slowly, and the grinding fineness is uniform. It is possible to get a good cup of coffee with the coffee beans.
A good cup of mocha coffee should be strong but not too bitter. With milk and milk foam, you can get a cup of fragrant milk coffee. The fragrant mocha coffee and the fine milk foam will attract attention in a short time. It is loved by the majority of consumers and has created a booming coffee market!
In the average family, the more economical choice is the moka pot, and it is quite personalized and beautiful without taking up space. The popular point is that most of the early materials were aluminum products, but now they are mostly changed to stainless steel plastic materials that are more harmless to the human body.
Step 1. Use Espresso-specific coffee beans. It needs to be ground finer than American coffee, but it is not powdery. Metal strainers leave residue and cause over-extraction that is too bitter, too astringent, and if the grind is too coarse, the hot water will pass through the coffee too quickly and cause under-extraction and lack of flavor.
Step 2. Put an appropriate amount of hot water at the bottom of the moka pot (usually, the amount of espresso will not exceed 60㏄).
Step 3. Put the coffee powder in the middle of the moka pot, in a container shaped like a funnel. The amount of each cup is about 8 or 9g. Flatten the coffee powder and squeeze it a little, but don’t. Press it too tightly and put it in the pot.
Step 4. Fully fasten the upper and lower seats of the Moka pot to ensure that the water will not seep out from the middle when boiling, and then heat the Moka pot from the bottom. You can use your hands or Put it on a special rack, and use an alcohol lamp or a gas stove to heat it until the water boils and flows to the upper seat.
Drip coffee pot
Not exactly a pot, but a way to make coffee. Place filter paper or mesh on top of the container, put coarsely ground powder, pour water from above (the technique of adding water is very important), and the coffee leaks out from below.
To brew a cup of drip coffee in the easiest way, you only need to prepare a filter (available in many cafes in the market, divided into heat-resistant plastic, ceramic and metal materials, which can be Choose according to personal preference) Next, you only need to take a mug you usually use, put the filter on the mug, put on the filter paper, pour in the ground coffee bean powder, prepare a pot of hot water, and you can be at home by yourself Brew a cup of delicious, hot, freshly brewed coffee. The filter paper dripping brewing method is mainly to let the coffee bean powder and hot water be fully mixed to dissolve the four flavors and aromas in the coffee, and then drip out through the filter paper. This method can filter the fat contained in the coffee. , protein and bad impurities, get a refreshing coffee, and take into account your health while enjoying the delicious taste.

Of course, if you have a bigger budget, investing in a good grinder is definitely worth it. Freshly ground coffee beans provide the aroma in the air and the deliciousness of the brew, making your investment worthwhile.
Water flow: The biggest skill for brewing filter coffee is to control the thickness and stability of the water flow. A stable and moderate water flow spirals out from the center point of the filter, just like a stirring rod. With coffee powder and hot water, all the richness and deliciousness are released. If you are already addicted to the filter coffee brewing method, you may wish to purchase another beautiful brewing pot at this time. People can easily pour out a fine and stable water flow, which helps you instantly have the brewing level of a professional coffee hand, and the deliciousness of this cup of coffee is not a problem.
Warm Cups: In addition, I would like to remind all coffee lovers that hot coffee must be drunk hot, which is the most delicious time for coffee. The action of warming the cup can prolong the heat preservation of the coffee, as long as the hot water is poured into the coffee cup first, the cup is warmed by the temperature of the hot water, and the hot water is poured out and then poured into the freshly brewed hot coffee. Helps maintain the heat of coffee and prolong the time of enjoying delicious coffee.
Step 1. Fold the next part of the filter paper along the suture and put it into the dripper.
Step 2. Use a measuring spoon to pour one portion of the ground coffee powder (about 10 ~ 12g for one person) into the drip glass, and tap a few times to make the surface flat.
Step 3. After boiling water in a teapot, pour it into a fine-mouthed kettle, pour the boiling water (water temperature is about 95 degrees) gently and steadily from the center point, and slowly begin to infiltrate and spread the boiling water in a spiral manner. ground coffee. Be sure to pour slowly.
Step 4. In order to extract the delicious ingredients, steam the expanded coffee powder for a while (stay for about 20 seconds)
Step 5. The second time Boiling water, pour slowly from the surface of the ground coffee. The amount of injected water must be consistent with the amount of coffee liquid extracted, and the amount of boiling water in the filter paper must be kept constant.
Step 6. Stop when the extracted liquid reaches the human weight. Discard it with boiling water remaining in the filter paper.
