How to determine and set the grinding degree of espresso coffee

Remove all the Xiaofei X bean grinder these days--by the way, change the stainless steel screws

The following figure shows the names of all parts of the bean grinder, of which 9 is the thread adjuster.

1. Thread pitch 1.8mm

2. Part 10 Scale adjustment cap 1--7 exactly half a turn

3. Compared with the above--thickness scale and the relationship between the tooth plate cutter group spacing is as follows

dial spacing

0 0um

1 150um

2 300um

3 450um

4 600um

5 750um

6 900um

7 1050um

As for the general postbox and other hand-operated bean grinders--

Key in hand-cranked shaft Thread diameter 8mm(ISO) Non-inch 5/16"thread...

ISO-8mm thread pitch is 1.25mm, that is, a turn down 1.25mm...

A common mailbox H-5, etc. has a circle of 6 grid card tenon position... That is, the upper and lower spacing of each grid conical grinding disc is 0.208mm.

The coffee powder passing through the disc cutter space refers to the vertical distance between the two discs, if the disc cutter is 60 degrees, the calculation

Then the vertical spacing between the two grinding discs a(or/)=1/2* the gap between the upper and lower conical discs b($>)

←ISO 8mm(D) thread (pitch 1.25mm)

███◤◢█◣◥███ /← Upper and Lower Cone Clearance b

██◤◢███◣◥██ Vertical spacing between two grinding discs a→

█◤◢█████◣◥█ ↑ Angle 30

Therefore, the relationship between each tenon and the gap b between the upper and lower conical disks and the vertical spacing a between the two grinding disks is as follows:

number of turns Clearance between upper and lower conical disksb Vertical spacing between two millstones a

1/6 (1 square) 0.208 mm 0.104 mm

1/3 (2 squares) 0.417 mm 0.208 mm

1/2 (3 squares) 0.625 mm 0.313 mm

2/3 (4 squares) 0.833 mm 0.417 mm

5/6 (5 squares) 1.042 mm 0.512 mm

1 (1 lap) 1.250 mm 0.625 mm

1 1/6(1 circle 1 box) 1.458 mm 0.729 mm

1 1/3(1 circle 2 squares) 1.667 mm 0.833 mm

1 1/2(1 circle 3 squares) 1.875 mm 0.938 mm

1 2/3(1 circle 4 squares) 2.083 mm 1.041 mm

And general brewing coffee, grinding thickness control

1. French press: Each coffee is ground into 100--300 coffee powders, about 0.7mm in diameter.

2. Follicle drip filtration: Each coffee is ground into 500--800 coffee powders, about 0.5mm in diameter.

3. Stopper: Each coffee is ground into 1000--3000 coffee powders, about 0.35mm in diameter.

Espresson: Each coffee is ground into 3500 coffee powders, about 0.05mm in diameter.

That will change it!! In addition to the Italian hand still not suitable, in grinding uniformity table think even better than professional electric grinder... It's good to work on your wrist over coffee.

Coming up--the office scanner--

#1 Scale (150um)

Scale #2 (300um)

#3 Scale (450um)

#4 Scale (600um)

#5 Scale (750um)

#6 Scale (900um)

#7 Scale (10500um)

This machine has a non-clearance and blunt teeth on the outer edge of the disk--so coffee grinds like a mortar--uniformity doesn't seem to be good--

above

#1--#2 Suitable for Italian coffee machine grind

#3 Fit Mocha POT Abrasion

#4--#5 Suitable for hand punch,Syphon grind

#6--#7 Fit Franch Press Abrasion

The following is a common #4.5 scale for hand flushing

The following is the fineness of Taiwan sugar super granulated sugar, consistent with the above hand grinding fineness

And the table salt below--it's about #3 grind.
