How to adjust the scale of the bean grinder?-how to adjust the scale of the Italian bean mill

The same scale, the same beans, in the case of fine grinding, the powder used overnight has changed? Even after cleaning a large amount of residual powder from the powder outlet at night, there is an increase in extraction time (there is a pressure gauge on the machine for reference, and the pressure is really high) whether the residual powder in the cutter head overnight will have an impact.

A few more words are needed here. First, take off the dial, screw off the ratchet, and use a 3mm drill to get through the end of the copper screw sleeve. Conversely, from the other end (the bearing end), hit with a 3.5mm bit until it touches the copper screw sleeve. Do not get through the copper screw sleeve. Tap from one end of the copper screw sleeve with a 4mm tap. Then the plastic core of the fixed bearing is sawed off with a hacksaw blade. Secure the disc, dial and ratchet together with two small screws. Remove the two retaining screws from the ground cover. Assemble: screw the ratchet core into the cover plate and install the locating pin at the same time. With a 4mm long screw, first fix the pointer, screw in from one end of the disc, pass through the core of the ratchet, then connect the core of the bearing, tighten the screw, and then return to two turns. Rotate to the inner side of the bearing and cover flat. If the screw is too long, it needs to be sawed off. Finally, the cover of the standby ditch is put back in with the original screw.

May I ask you if there is something wrong with my operation that I haven't noticed, or is it a machine problem?

The scale is just a reference, different brands have different grinding scales, and the performance of the same model bean grinder of the same brand under the same scale is not exactly the same. it is better to understand it this way: the scale just tells you which direction is thick and which is fine. when you find a suitable powder thickness, the role of the scale will show a little bit. The premise is that only your bean grinder, and can not change the beans, the amount of powder does not change, the strength of the powder can not be changed.

Remember a little trick: when you find the right powder thickness, twist it with your hand from time to time, pinch it, feel it with your body and write it down as much as possible, so that even if you change the bean grinder, you don't have to rely solely on the scale to judge. If you pinch it with your hand, it will be significantly thicker, which can greatly improve your efficiency. Different bean grinders have different adjustment dials, so you should check the model of the coffee grinder and read the instructions carefully to determine the direction and strength of the dial. In general, if you keep in the habit of checking the settings of the bean grinder, you only need to make very small adjustments. As long as you move the turntable within 3 mm, you can change the thickness of the powder. Although 3 mm is a very small number, the grinding time of the same coffee beans will change 3-5 seconds with the resulting coffee powder to make a cup of coffee to ensure the accuracy of the weight, flattening and pressing steps. The traditional method of making espresso (Ristretto) uses a water / flour ratio of 1:1 (i.e. 18 grams of coffee powder is used to make 18 grams of coffee) or 1:2 (i.e. 18 grams of coffee powder is used to make 36 grams of coffee), while a regular espresso uses a water / powder ratio of 1:2 (i.e., "Normale"). Test the quality of the coffee and the extraction time. Constantly adjust the dial to make the powder reach a perfect thickness.
