What is the standard of grinding calibration of bean grinder-Italian coffee grinder calibration

Bean grinders are generally classified by coffee extraction, which are divided into two categories: single coffee grinder and Italian coffee grinder! According to the structure of the grinding plate can be divided into flat knife, cone knife, ghost teeth three categories! You can break up manpower and electric power according to the way you work. But no matter what category, my personal advice is to buy the best bean grinder that you can afford.

Generally speaking, the bean grinder of the ghost tooth grinder is only suitable for grinding single coffee, that is, coffee powder with thicker particles. This kind of bean grinder is represented by Japan's Fuji R220 and Taiwan's Yang family's Pegasus 207N, while the high-end ones are American grinder 875 and Fuji R440. Compared with flat knife or cone knife, this kind of grinding plate has an excellent sense of balance and thickness in terms of extraction flavor, but the details are not as accurate as flat knife. (to put it simply, it is like the difference between the gallbladder machine and the stone machine in the stereo.) it is often the first choice for ordinary coffee lovers to make a single bean grinder! The performance of the two bean grinders I recommend below are basically the same! But the price of Fuji is about three times that of Pegasus. However, Fuji is small in size and fine in workmanship, so it is more suitable for a corner of the home. Pegasus is a rough undertaking, but this image does not affect its good grinding products.

The new imitation s with pressure gauge, the mill is 900n, at the beginning, everyone's scale is 2: 3.5, I start to use 3 degrees, wipe, the pointer directly jumps to the end, can't wait to turn clockwise two more times, turn off, re-grind, 3.5, and then, yeah, not out, 4.0, so far is light pressure, afraid of crushing, 4.5, finally out, no oil, about 27,28seconds, I can not swallow this breath. Has spent nearly a pound of beans, and then back 3.5, bang burst something, scared to death, quickly turn off the phone, touch! * ~. Electricity @ (.com) + ╭ (╯ ε ╰) ╮, pull the plug, take a look, the boiler top of the hard tube fell off, was sprayed out by pressure, looking for the seller, re-sent a tube, installed, just tried, 3.5 light pressure, not out, the heart is very calm, so to ask everyone, imitation s with 900n mill, what scale what pressure, can qualified product with thick grease?
