Introduction of coffee machine and general knowledge of choosing and buying brocade coffee

Just as washing machines can wash clothes and vacuum cleaners can clean homes, every invention of human beings has changed our lives. Life is simpler and more convenient, and we are becoming more and more lazy. In a comfortable life, more and more people are looking for a petty bourgeoisie tone, which is what we call a unique taste today.

Much like Chinese tea culture for more than 5,000 years, coffee was recorded as early as 850 AD, from the earliest roasting, grinding, blending, and tedious steps to pouring coffee beans and milk into it today. A few buttons can enjoy a variety of flavors of coffee, which is also a progress of life.

Some people think that the coffee machine is a luxury and it is totally unnecessary to spend thousands or even tens of thousands of yuan on the coffee maker. In fact, the author would like to say that the birth of the coffee machine is not accidental, it is precisely because people's continuous pursuit of quality of life, the achievement of the coffee machine, an inconspicuous small household appliances, but changed our lives.

Classification of coffee machines

The most commonly heard of are American coffee machines and Italian coffee machines. I have seen high-end coffee machines with full functions in coffee shops, and most companies are also equipped with multi-functional coffee machines with comprehensive tastes, while the most common domestic coffee makers are simple coffee pots without grinding functions. how many kinds of coffee machines are there?

From the point of view of operation and working mode, coffee machines are divided into semi-automatic coffee machines and fully automatic coffee machines, but at present, most of the coffee machine products on the market are fully automated; according to the way of use, coffee machines are divided into commercial coffee machines and household coffee machines. 80% of commercial coffee machines are Italian coffee machines and 80% of household coffee machines are American coffee machines.

Household Italian coffee maker

At first, it was a semi-automatic coffee machine, which we used to call Italian coffee machine, which got its name because it originated in Italy. Today, Italian coffee machine has been fully automated. This kind of machine initially according to the manual operation of grinding, pressing, loading, brewing, manual removal of residue. The principle of Italian coffee machine is to use a mixture of high-pressure steam and water to quickly pass through the coffee layer and instantly extract the coffee, so that the coffee temperature is very high, the content of caffeine and other impurities is very low, and the taste is rich.

Italian coffee machines have large commercial machines with double faucets and triple faucets, as well as small single-tap household machines. the newer machines are also equipped with electronic water control, which can accurately and automatically control the amount of coffee brewing. And they all have the function of steaming milk foam, which pressurizes the hot water to about 9 atmospheres and then flows through the powdered coffee beans in the metal filter to brew the coffee. The coffee brewed by this kind of pressurized hot water is thicker and can make a lot of fancy coffee, such as cappuccino, latte and so on.

Advantages: according to the rigorous working method, can make high-quality Italian coffee with strong export feeling; fully functional, you can make a lot of fancy coffee.

Disadvantages: the price of commercial Italian coffee machine is too high, some as high as tens of thousands of yuan. The price of household coffee is low, ranging from 300 yuan to 1000 yuan, but the operation is slightly complex, requiring some technical experience, maintenance and cleaning trouble.

American coffee machine

Due to the high cost of Italian coffee machine, slightly complex operation, mainly for commercial use, and then derived from the American coffee machine, American coffee machine is fully automatic, there are no semi-automatic products, mainly for household use. The principle is to use hot water to drop on the coffee powder, extract the coffee, and the extracted coffee will drop into the glass coffee pot below. So the American coffee machine is usually divided into two layers, the coffee powder is placed in a funnel-shaped container with a filter, the lower layer is a coffee pot made of glass or ceramic, and the cold water is separated by another interval. When starting, heat the cold water to about 90 degrees Celsius and gradually introduce it into the funnel-shaped container, so that the hot water passes through the coffee powder and flows into the coffee pot below, thus making coffee.

The function of the American coffee machine is usually relatively simple, and the operation is correspondingly more convenient. All you need to do is press the button and wait for the delicious coffee to appear. Its convenience is much better than that of the traditional Italian coffee maker. Most of the American coffee machines are suitable for household use, and most of the Philips and Siemens coffee machines common in supermarkets are American coffee machines.

Advantages: the American coffee machine is easy to operate, fast and efficient, and is deeply loved by public families.

Disadvantages: because it is mainly for family rather than business, the function and taste are not as comprehensive as the traditional Italian coffee maker.

Coffee pot = coffee machine?

Nowadays, in the home appliance store, people can see not only the expensive automatic coffee machine, but also the coffee pot. The price of a coffee maker is much lower than that of a coffee maker, about a few hundred yuan, so is a coffee maker and a coffee maker the same thing?

We have already introduced the coffee maker before, so how does the coffee pot make coffee? Most coffee pots have no fine grinding and brewing function, the function is very simple, usually only need to put the coffee powder into the filter, and then through the process of adding water, boiling, brewing and so on, to make coffee. There are two kinds of coffee pots, siphon and drip filter, that are common on the market.

Advantages: coffee brewed in a coffee pot usually tastes better than instant coffee.

Disadvantages: due to the direct use of coffee powder, milk, sugar and other seasonings can not be added, in the workmanship, the material and temperature control effect of the ordinary coffee pot can not be compared with the professional coffee machine. According to the milk ratio and grinding time setting, the coffee maker can easily make cappuccino and other specific flavors of coffee, at this point, the coffee maker is obviously not comparable to it.

Capsule coffee machine

Capsule coffee machine is a new type of coffee machine in recent years. The so-called capsule coffee machine is that manufacturers put coffee powder into a plastic capsule in advance and then fill it with nitrogen to keep it fresh. when we drink coffee, as long as we put the coffee capsule into a special machine, we can quickly drink a cup of strong coffee. In principle, the capsule coffee machine also saves the grinding process. More specifically, the capsule coffee machine is a coffee pot that specializes in brewing coffee capsules.

Capsule coffee machine is also invented by foreign countries, the purchase channel, the domestic is still a lot of see, ordinary consumers can buy through Taobao, Haitao and other channels.

Advantages: the price of the capsule coffee machine is cheap, brewing coffee is more convenient and convenient, the maintenance and maintenance of the product is easy, and it is easy to operate.

Disadvantages: some capsule coffee machines can only be compatible with one kind of coffee capsule, there are limitations, the price is relatively high, to paraphrase: "weapons are very cheap, but ammunition is very expensive."

The author's point of view: although the 100-yuan coffee pot common in the store is very attractive in price, it lacks the important step of grinding and milk ratio, so the coffee tastes general and is only a little better than instant coffee. If the choice is careless, even the taste is not as good as instant coffee.

Coffee lovers who like to have plenty of food and clothing for themselves might as well choose semi-automatic Italian coffee at home. The price is relatively low, generally acceptable, suitable for specializing in the production of boutique coffee. Capsule coffee machine is a good choice for office workers, moderate price, fool-like operation, save time, effort and worry, that is, drink as soon as you want.
