Coffee automatic grinder, the bigger the scale, the finer the powder?-what brand is the manual coffee bean grinder?

Coffee automatic grinder grinding scale bigger powder finer?- What brand of manual coffee grinder is good

Contrast this principle with the first rule. If coffee powders of different grinds are mixed together, the concentration of soluble powder will be inconsistent, and both sour and bitter will be extracted. It is conceivable that this cup of coffee will turn into a cloudy and smelly liquid.

The second is the problem of friction and heat generation in the bean grinder. It is normal to generate heat during grinding. This is important because heat obviously damages taste and aroma. The price difference between a bean grinder with metal blades and a bean grinder with ceramic blades is here. After international multi-party research, experts believe that under extremely common speed and load conditions, the instantaneous high temperature generated by friction in local areas of the metal surface can be as high as 500-1000 ° C.

Therefore, grinding coffee will produce heat, which is inevitable, but depending on the structure of the grinder, the heat will also vary. The way the grinder grinds coffee beans is roughly divided into two types. One is to grind coffee beans with two grinding blades engraved with shallow grooves. We call it a parallel grinder. Most manual grinders belong to this category. The other is represented by a shredding grinder, which combines coffee beans with two sets of rollers with sharp edges that are perpendicular to each other, which is the so-called conical blade grinder.

When this is done, most brands of grinders on the market will have 60 grams of ground coffee stored in them. In our experience, you need at least 100g of coffee powder in the grinder to start debugging the machine, and the debugging effect is more obvious. So, you need to make at least three more espresso cups before you start tuning the grinder. When you're done, you need to make at least five more cups of coffee. This is very important! The last thing you want to do is fail and then re-test and re-tune your machine, which is when you need to decide if you want to re-clean the coffee mill. To ensure the quality of your coffee, if your adjustment range is more than 2 marks, you need to thoroughly clean your grinder. Although we don't want to waste coffee, in our experience, the results are better after cleaning the grinder.

[Analysis Results]

If you get the results you want, congratulations! But remember, this is just the beginning. Assuring the accuracy of the data in the test does not guarantee the perfect quality of your coffee, but it is still a shortcut to the best quality of your coffee! If you succeed in calculating the recipe for one type of coffee using this method, you can start testing the data needed to make other types of coffee, such as drip coffee. Then you know what data is useful and what data is useless.
