Which electric bean grinder coffee machine has a good brand recommendation?

There are already a lot of excellent bean grinder comments on Coffeegeek (http://www.coffeegeek.com/detailed/innovagrinder) and elsewhere). In my opinion, these comments cover ergonomics, brands and many other areas that I have never covered before. As I said at the beginning of this article, I won't try to get into these things. I'm only interested in the kinds of pieces and their ability to grind the coffee powder needed for Espresso.

Why do I need a bean grinder?

Fresh: coffee beans last longer than ground coffee powder. Once you grind the coffee, the aging reaction speeds up many times, which is the amount of powder you grind the coffee beans into. In terms of the grinding fineness required for Espresso, this multiple is a large number.

Precision: Espresso coffee requires a strict set of conditions to complete a complete extraction. Given a particular Espresso machine, you can generally control the grinding, dose and tamp processes to achieve this. Of these three variables, grinding is the most important, followed by the amount of powder loaded, and finally compaction. Coffee is hygroscopic and can absorb moisture in the air, so changes in temperature and humidity will have a significant impact on coffee grinding.

A set of cast steel grinding plates are placed on the threaded brass bracket, but the grinding pieces are too small and are not as well designed as the big ones (pay attention to the gaps). There should be no problem with short-term application, but it looks like it will wear out quickly. I have seen reports that Saeco cannot grind the fineness required by commercial Espresso, but it is not a big problem for ordinary home use. (original: but had no trouble on the second finest setting, I don't know how to translate it.)

Solis (All), Dualit, DeLonghi KG100, Starbucks Barista, Bodum.

All these bean grinders use the standard Solis conical grinding kit, and all (except probably Bodum) are manufactured by Solis. There is no doubt that this grinding kit is very suitable for making excellent Espresso bean grinders. Unfortunately, the bearing bracket of the upper grinding plate is not adjusted by a thread system, but by a bevel and wedge system. In my opinion, this adjusting device is not accurate enough, especially when the bean grinder begins to wear out as time goes by. I would not hesitate to recommend this bean grinder for those who use household 53mm or smaller home Espresso machines with brewing handle heads and pressurized filter bowls, while for those who use larger cooking handles and unpressurized filter bowls, I would not recommend this bean grinder.

In order to grind enough fineness, such machines need to push the Solis grinding kit to the end of the adjustable range, which potentially increases wear and shortens service life. So I can't recommend this one for long-term use. Note that some of the models listed above are not as thin as Espresso needs and need to be adjusted to get the correct thickness. You can find out how to do this on Ken Wilson's UK website (www.kwilson.fsnet.co.uk/coffee_index.htm). You can also find a lot of useful information about the bean grinder there.
