The difference between the head of coffee machine E61 and other heads-the difference between mocha pot and coffee maker

First of all, the powder from the bean grinder.

Ideally, the powder from the bean grinder should be micro-particles of fixed size, and to reach a certain fineness, it should be evenly placed in the powder bowl on the handle of the coffee machine, because the density is the same, when the water pressure of the boiling head is evenly distributed on the whole pressed powder, the pressure obtained in this way is stable.

But in fact, it is very difficult to do this, thousands of pieces of bean grinder out of the powder will still be different in particles, and there will be some very small coffee powder (residual powder), it is very difficult to make the density of coffee powder in the powder bowl to be exactly the same.

The more uniform the powder produced by a good bean grinder, the less residual powder will be.

Not to mention the poor bean grinder, even a certain fineness can not reach, the density is completely uneven, resulting in the pressure on pressed powder is very uneven, not to mention whether it can be stabilized on the pressure of 9bar.

The bean grinder will not be introduced. If you want to introduce it, it will be a big one. Open another post in the future.

Bean grinder is basically a penny of goods, I think the price of bean grinder from 1800 yuan, basically can be used.

An one or two hundred yuan bean grinder doesn't work on an Italian coffee machine at all, so you'd better save it and buy a bag of beans.

In the Italian coffee machine, the temperature value is mainly affected by the size of the boiler or heating block, as well as good heat conduction materials, there is an obvious difference between the toy machine and the professional Italian coffee machine. In general, many standard toy machines are equipped with small boilers (below 200ml) or small heating blocks, so it is difficult to achieve a stable temperature, and the temperature fluctuates greatly in the process of coffee extraction. The machines of many small household appliance brands are like this (such as Cankun, Delong, Electrolux, etc.). After all, these brands are not professional coffee makers. Another thing to consider is a good heat conduction material, a good machine has a better circuit and pipeline design, using copper or stainless steel as the main material of the coffee machine, they have good thermal conductivity (to ensure uniform and stable temperature). Otherwise, it is still more than 90 degrees from the boiler to 70 or 80 degrees from the coffee machine, which will be more obvious in the low temperature environment.

Because the appearance and design imitate the foreign very successful home semi-automatic machine Lanchio silvia, it is generally called imitation s, which can be won on Taobao for about 1600 yuan. Because of its high performance-to-price ratio, it is very popular among novices in coffee forums.

Its boiler is not big, 300ml, but under the troubles of many friends in the forum, the current version design is still relatively reasonable, with some points for attention, it is possible to produce a cup of espresso (espresso) with more than 80%. Because the boiler is small, it is better to wait for a continuous cup. In fact, the introduction of this machine is quite perturbed, basically coffee birds feel that it is not to the extent of the entry machine, considering its popularity in the coffee forum, or introduce it.
