Accuracy adjustment of domestic small flying eagle bean grinder-domestic small Fuji ghost tooth grinding machine

The tooth pattern of the round-edge cutter head is relatively large, the tooth pattern is conical, and the cutting and crushing account for a relatively average proportion. In terms of the feeling of use, the speed of the round blade is obviously faster than that of the flat knife, the flake and fine powder are less, and the whole is more uniform.

Coffee beans contain oil, so the bean grinder must be cleaned after grinding, otherwise the grease will be fouled and will smell stale after a long time, and even the most advanced beans will be ground into a strange-smelling powder. After each use of the bean grinder, be sure to wipe the blade table with the wet market and clean the plastic top cover with warm hot water.

The shorter the cooking time, the finer the ground powder; the longer the cooking time, the thicker the ground powder.

Reduce grinding and generate heat. (grinding heat will cause the aroma of coffee to dissipate early)

The particle size is uniform. (uneven particle size will make it impossible to control the brewing time.)

Therefore, the use of family-style manual bean grinder, it is necessary to gently rotate, as far as possible so that it does not produce friction heat.

The small flying eagle with round blade has upgraded the material of the scale adjusting gear. After the redesign of the cutter head, the grinding is more uniform, the fine powder is less, and the grinding speed is obviously faster than that of the flat knife small flying eagle.

Shallow roasted coffee has a lower extraction rate and should be ground slightly, but unless you are eosinophilic, if you serve shallow roasted Geisha Panama or Kenya at scale # 2.5, it is easy to extract more solute, acid to pout, it is recommended to adjust a little thicker to # 3.5 to inhibit acid dissolution. In addition to looking at the degree of baking, it is more important to understand your preference for beans in the place of origin. It is difficult to have a universal grinder. The smaller the grinder, the finer the grinding, the thicker the coffee. As far as the most commonly used Flying Eagle grinder is concerned, scale # 3.5Fei 3 is the most suitable for hand flushing. If it is further thickened to the scale # 4, it can also be used to flush heavy roasted beans or shallow roasted coffee beans by hand. But the extraction rate is too low, there should be insufficient extraction, taste is too thin heart preparation.

Hand flushing with scale # 3 is the safest and is suitable for light, medium and deep baked popular tastes, but deep baked beans may be too bitter if they are washed by hand with a scale of # 3. If you adjust the fine half degree to # 2.5, the extraction rate will be about 0.5%-1.5% higher than # 3, the amplitude is very large, the room for tolerance for mistakes becomes smaller, the water temperature is too high or the extraction time is too long, and it is easy to flush out bad coffee with a slight error.

However, some heavy-tasting veterans like to make light-roasted, medium-roasted and medium-deep-roasted coffee with a hand of # 2.5, because the sense of stickiness and smoothness is better than that of # 3, but the aftertaste is very far away, but the risk of throat biting is also greatly increased. Deep-baked baked beans entering the second explosion intensive stage had better not be washed by hand with # 2.5, and the failure rate is very high.
