Coffee machines People apply electronic technology to coffee machines to realize automatic control of the whole process of brewing coffee, such as grinding, pressing, filling, brewing, and removing residue, creating a coffee machine.
use
Step/Method select coffee powder. In fact, coffee beans are fine, so you have to grind them yourself. There are various flavors of coffee, what vanilla flavor, and there are 5 levels of flavor, from MILD to DARK.
Use filter paper, either made of bamboo or ordinary. Unfold the filter paper into a funnel shape, and put a few spoonfuls of coffee powder into the filter paper according to personal taste (generally, there will be as many coffee packages as you put). The benefits of filter paper are great, not only can filter the slag, but also increase the time for water to flow through the coffee powder, make the coffee more fragrant, and it is also convenient to clean.
Put the coffee and filter paper into the filter basket like this, it is the filter basket, put it as straight as possible.
Pour all the water in the coffee pot into the water reservoir behind the coffee machine. The scale in the water reservoir should be consistent with the scale of the coffee pot.
Close the top cover, place the coffee pot like this, and turn on the switch.
Coffee is coming out, you can do other things.
Semi-automatic
Semi-automatic coffee machine, commonly known as handle machine, is a traditional Italian coffee machine. This kind of machine follows manual operation to grind powder, press powder, fill powder, brew, and remove residue manually. Such machines include small single-head household machines, double-head, three-head large commercial machines, etc. The newer machines are also equipped with electronic water volume control, which can accurately and automatically control the water volume for brewing coffee.
This type of machine is mainly produced in Italy and is very popular in Italy. Its main features are: the machine is simple in structure, reliable in work, easy in maintenance, and can produce high-quality Italian coffee according to the correct use method. The shortcomings of this machine are also a little bit: the operator must be strictly trained to make high-quality coffee with this machine, and an excellent barista can provide customized coffee.
But if you can make a cup of delicious coffee by yourself, it is indeed a spiritual enjoyment.
Think about it, what else can compare to your own coffee?
Fully automatic
People apply electronic technology to coffee machines to realize automatic control of the whole process of coffee brewing, such as preheating, cleaning, grinding, pressing, brewing, and purging, creating a fully automatic coffee machine.
The high-quality fully automatic coffee machine brews coffee in accordance with the most scientific data and procedures, and is equipped with a complete protection system. It is convenient to use, and the coffee can be obtained with a single touch, which is more convenient than The product of a traditional coffee machine.
The structure is more complex, requires good maintenance, and the high maintenance cost is the disadvantage of this machine. However, the automatic coffee machine is convenient, fast, consistent quality, high efficiency, and the outstanding advantages of the operator without training make it more and more popular with customers.
Manufacturers are mostly fully automatic coffee machines produced in Switzerland, Germany, Italy and other countries, with a wide variety of products. Among them, the fully automatic coffee machine made in Switzerland is ingenious and unique in design. Fully automatic coffee machines made in Italy, simple appearance, stable and reliable quality, and are well-known in the international coffee machine industry.
Fully automatic coffee machines are divided into large, medium and small types according to the number of cups brewed per hour (generally from 60 cups to 280 cups per hour). There are many varieties, suitable for offices and homes.
principle
Since Luigi Bezzera launched the first commercial coffee machine with vapor pressure in 1901, whether it is Pavoni Gaggia
Or other machines that use steam or pistons as pressure have only one boiler: the bottom of the boiler is hot water for brewing coffee, and the top of the boiler provides steam. But in order to produce steam, the entire boiler must be heated to boiling, making the heat close to the boiling point. The water burns the coffee powder, loses the aromatic oils hidden in the coffee powder, and extracts more bitter coffee.
Since the water used for brewing coffee is heated in a large boiler, the water will become stale if left in the boiler for too long, and the temperature difference of the hot water will increase due to the use of steam. The temperature difference of the hot water for making coffee.
In order to improve the temperature difference, Ernesto Valente established the world’s first FAEMA with a pump as a pressure source in 1960.
In E61, the heating method of the water used to brew coffee is changed, so that the water used for brewing coffee does not directly contact the heat source, but uses a method similar to water insulation.
FAEMA
The E61 boiler (hereinafter referred to as the outer boiler) is in the middle of a pipe (hereinafter referred to as the internal pipeline), which uses a pump to introduce fresh cold water into the internal curved pipeline. When the pump pushes fresh cold water through this pipe, the cold water will become hot due to the hot water in the outer boiler, but there is a pipe wrapped around it, so the fresh water will not come into contact with the hot water of the outer boiler. The reason for the curved shape of the water pipe is to make the cold water have enough time to contact the outer boiler and become the hot water temperature just suitable for brewing coffee.
Due to the hot water circulation in the boiler, the brewing temperature of each cup of coffee is very close, whether it is brewing one cup an hour or one hundred cups at once. In this way, not only can the temperature difference be reduced, but also the freshness of the water can be taken into account. The hot water in the outer boiler is only used to produce milk foam steam, and will not be used to brew coffee.
This is the principle of the single-boiler heat exchanger. Until today, more than thirty years later, the internal structure and principle of most Italian coffee machines are still very close to FAEMA E61.
From the above description, we can infer that the larger the capacity of the external boiler, the lower the temperature difference of the hot water for brewing coffee, and the more the temperature difference caused by the use of steam can be reduced.
Buy
To get a good return on the coffee machine as part of the investment, the choice of coffee machine is very important.
First, determine the type of coffee machine. In general professional coffee shops and coffee bars, traditional Italian manual coffee machines are the first choice. Because in these places, well-trained professionals use traditional Italian coffee machines to grind and brew instantly. Not only do they create a strong coffee atmosphere, but the air is filled with the aroma of coffee, so that guests can experience the unique coffee charm. And restaurants, cafes, restaurants, bars, and offices mostly use automatic coffee machines. Because of the large passenger flow and concentrated demand in these places, the use of fully automatic coffee machines will fully demonstrate its advantages of convenience, speed and high quality, so that customers can enjoy coffee of constant quality and excellent quality in the shortest time, and get physical and mental satisfaction.
In addition, you can also choose the coffee machine of Xiaoxiong Electric, which has a humanized design, simple operation and convenient cleaning, so that you can enjoy the alcohol of coffee at any time.
Which brand of coffee machine to choose is also very important. The products of famous international brands and Xiaoxiong Electric have good quality and the supply of spare parts is guaranteed. Because of the small output of unknown brands, the supply of spare parts is not guaranteed and the risk is greater.
The coffee machine market in my country is still in a disorderly stage. The market competition is very fierce. Some foreign manufacturers squeeze outdated models with unsalable foreign technology into the Chinese market. Some domestic unscrupulous businessmen use home machines as commercial machines, confusing semi-automatic and Fully automatic machines make huge profits from them and entrap users. Some users spend a lot of money to buy low-end cheap goods or a pile of industrial waste.
To buy a coffee machine, do market research, collect information extensively or consult a professional coffee maker or company to determine the type of coffee machine you need: the next step is to choose a qualified supplier. Professional coffee machine suppliers not only have rich experience, can provide you with multi-faceted reference, help and the most reasonable price for your choice of coffee machine, but also have a good after-sales service system and sufficient and timely supply of spare parts.
maintenance
After you buy it back, please read the instructions carefully.
Because the new machine has the smell of plastic material, it is harmful to the human body, so before using the electric coffee pot for the first time, you should boil two pots of boiling water to remove the bad smell.
To clean the leaky screen and filter screen, soak in water for a period of time, then rinse with water, and rinse back and forth from the front side. Do not scrape with hard objects to avoid damage and affect use.
After use or cleaning, wipe it with a dry cloth and place it in a place that is not easy for children to touch. Do not turn it upside down or press it with heavy objects.
