What do you think of the rough dial of the bean grinder-mazzer bean mill thickness adjustment

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 installed back with the original screw.

It should be noted that when the dial and ratchet are fixed together, pay attention to adjust the zero position. It's best to mark it when you remove the ratchet. In this way, the original dial is used for coarse adjustment. The middle screw is adjusted infinitely. The fine-tuned pointer is the minute hand of the waste electronic clock.

My Zhenghuang M520A was bought for Mo soybean powder last year. The powder box is a stainless steel cup, which avoids static electricity completely. Its disadvantage is that there are more residual powder.

Turn on the grinder for 10 seconds and discard the coffee powder (these are coffee powders that have not been adjusted).

Use the coffee powder to make a cup of coffee to ensure the accuracy of the steps of serving, flattening and pressing powder. Test the quality of the coffee and the extraction time. Constantly adjust the dial to make the powder reach a perfect thickness.

Debugging of electronic bean grinder

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 for 3-5 seconds to observe the coffee powder. High-quality coffee powder should be powdery 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. When the coffee bean enters the grinder, the blade in the grinder will crush the coffee bean into powder.
