Home coffee machine purchase guide which brand of home coffee machine is good?

I have been in the small circle of coffee lovers for some days. I have also used some coffee utensils and equipment, and many friends have asked me about what coffee utensils and equipment to buy, so I would like to write about my experience in this area. it can also let some friends have some preliminary understanding, but also can take fewer detours.

After thinking about it, I still want to start with the coffee machine at home, because I like coffee friends around me or ask me more about the coffee machine. On the one hand, the more people like espresso, and everyone knows that espresso is still made by machines. Second, coffee machines are not as common as our kettle and microwave ovens, so some players do not know the working principle and selling points. Therefore, it is easy to be fooled by the seller. Third, since it is a machine, it is easy to ask for a price of 500, 600, 700 or 800. For wages or students, it is really necessary to ask clearly before buying. So I think it's better to start with the coffee machine to solve everyone's problems.

Well, first of all, I would like to introduce to you some coffee machines that can be bought in China. Here I would like to add that the machine I am talking about here refers to the Italian coffee machine, not the American dripping machine and the fully automatic machine.

First of all, there are some coffee machines that are known as export and foreign trade orders. There are several common ones on Taobao, and the prices are all about 500 yuan.

Followed by Taiwan's small home appliance brand Cankun, this brand of coffee machine is mainly 1817, and 1817 related series 1817D, 1819, and so on. The prices of this series are all around 850 yuan. There are also some models of Delong, such as EC-155, for this class of household phones.

Cankun 1817, this price is absolutely classic.

There are also Saeco Nina imported machines of this grade, with prices ranging from 1500 to 2300 yuan.

The next one for the household machine is about to reach the stage of 4000-5000 yuan. At this stage, there are Huijia KD-210 and the small S (Rancilio Silvia) often said by insiders. The person who buys this level of machine already has a fever, if you consider this level of machine again, congratulations, you have been poisoned, .

Further up is the 6000 yuan level, which you can only choose from the Nouva Simonelli Oscar (Oscars for short). If you want a higher demand, then the elegant Shuttle is your choice, with prices ranging from 7600 to 8900.

If the above machines can not meet your requirements, then you probably will not read my blog here, so I will not continue to write.

The above machines are all used to make espresso, but the price is very different, from 400 yuan to 9000 yuan, what is the difference in their espresso? how can we judge it?

So let's dig into the machine itself first, and let's think about what espresso is. To put it simply, espresso is an espresso made (extracted) from an Italian coffee machine. It has a strong flavor and a liquid with thick fat. So what happened during the extraction of espresso? through years of practice and verification, Dr. Illy modeled the extraction process of espresso for the first time. There are five variables in the model:

V = the resulting espresso volume

T = the temperature inside the coffee pressed powder

T = coffee extraction time

= the pressure difference between the upper and lower sides of the coffee cake

R = head loss of Coffee pressed powder

And the relationship between these variables is

You don't need to understand the above model here, you just need to know that we've identified V of the five variables as 30ml, which is why the espresso you see is always a small cup. The extraction time is determined to be about 25 seconds to 30 seconds, and the pressure difference is determined, which is basically 9 atmospheric pressure. When the equation is balanced under these fixed conditions, the cup of coffee we get is about 30ml, and the liquid is espresso.

So the basic definition of espresso is the 30ml thick coffee liquid obtained by pressing 15 grams of coffee powder in 25-30 seconds with high temperature pressure water (9 atmospheric pressure).

According to the above definition of espresso, the factors we need to consider when making espresso are water temperature, pressure, coffee powder, and extraction time. Among these factors, the pressure and water temperature are directly related to the coffee machine. So when we buy a coffee maker, we have to consider the pressure of the coffee maker and the way the water is heated.
