How to use a manual bean grinder and how to adjust the thickness

In general, the distance between the correct weight, flattened and powdered pressed powder and the outlet should be 5-6 mm. If the height of pressed powder is not in this range, you should try to adjust the powder output of the bean mill (that is, grinding and pulverizing time). When adjusting the amount of powder, the range of each adjustment should be between 0.2 and 0.3 seconds, and after each adjustment, you need to re-test the quality of the coffee.

To observe the coffee powder, the high-quality coffee powder should be powdered and gravel. If the coffee powder is soft, like flour, it means the powder is fine. On the contrary, if the coffee powder feels tough and rough, it means the powder is too coarse.

The debugging of the electronic bean grinder mainly aims at two variables, the amount of powder and the degree of grinding. These two variables are mutual. If you change one of them, the other will also change.

Electric grinder has sawtooth type and rotary wing type. The sawtooth electric grinder grinds the coffee into an appropriate thickness and then puts it in a basket, and is equipped with thick and thin buttons, which can automatically set the size. Most of these electric grinders are expensive products.

The electric grinder mainly used in ordinary bulk is the mini rotary wing grinder, which is very similar to the bean mixer for grinding dietary beans. Since there is no device to adjust the size of the rotor electric grinder, if you want to grind it to the desired thickness, it can be adjusted by time.

In particular, if you want to use a rotary wing electric grinder to grind uniform coffee particles, shaking the grinder up and down is the key point! It is important to grind the coffee to the desired size while confirming the process and appearance of the grinding, but if you are proficient to a certain degree, you can tell the thickness of the particles by the sound you make when shaking. It's not that sound, and it's not this voice. It may sound like advertising copywriting, but in fact, the finer the particles, the lighter the sound.

1. Is the middle shaft of the bean grinder stable when you rotate? will it sway left and right? if it is very stable, the thickness will be relatively uniform.

2. For the ground powder particles, you can take a look at the evenness of thickness and thickness. The more uniform the better.

3. Fall, in fact, it is not necessary, just to roughly judge the overall material and texture
