How to make ramen noodles on a ramen machine

In this article we will explain in detail how ramen noodles, like those served in Ramen restaurants in Japan and around the world,
are produced – i.e. on specialized, usually roller-type, noodle machines capable of processing ramen noodle dough with hydration
ratio ranging from ~25% (e.g. for Hakata style ramen noodles) to ~45% (e.g. for Tsukemen style ramen noodles).

Depending on circumstances of available space and personnel, Ramen shops or other food businesses offering fresh craft ramen noodles may not necessarily produce noodles directly where they serve them (as noodles can either be made at some other location, or sourced from a third party supplier). But regardless of sourcing, most Ramen shops use machine-made noodles for their offerings.

In our example below we will use wheat flour called “Tsukemen Shin Men” made by a Japanese company NIPPN, with a protein
and ash content of 10% and 0.37% respectively.

The noodles below have a nominal water ratio of 38%, and thus belong to a category of medium hydration noodles.

For demonstration purposes we will use “Richmen Type I CE” ramen noodle machine (CE means that the machine conforms to European safety regulations, and can thus be imported to countries members of the European Union). Similar models of ramen noodle makers for North American are also available.

The ramen machine used in the example can produce up to 100 portions of fresh craft ramen per hour (may vary depending on a recipe and production techniques).

Standard ramen noodle ingredients are: wheat flour, water, kansui (usually a mixture of sodium carbonate and potassium carbonate), and salt.

ramen noodle ingredients

Thorough measuring is a key for good ramen noodles. In our example we will use 4000 g of flour.

Since kansui is usually added in a proportion of 1% to the weight of flour, we will add 40 grams of it.

Salt is also added in the amount of 1% to the weight of flour (thus, 40 g of salt).

salt for ramen noodles

Since our goal is to have a nominal hydration of 38% we will add 1440 g of water: yes, 4000 x 0.38 = 1520 g but because kansui and salt are considered as a liquid ingredients (as they can dissolve in water), we will add 1440 g

(4000 x 0.38) – ((4000 x 0.01) + (4000 x 0.01)) = 1440 g.

After weighing the required amount of water, add kansui and salt into it.

Put the flour into a mixer tank of the ramen machine, and close the lid.

Press the START button on the ramen machine mixer unit.

During this 1 minute of “dry mixing” flour will be properly conditioned for ramen dough making.

After the first minute of dry mixing is over, set the timer for 4 minutes, start the mixer, and pour in 2/3 of the water solution through a lid.

After most of the water has seeped into the tank, use spatula to push the remaining amount through holes on the lid.

After 4 minutes of mixing, open the lid, and remove dough residues accumulated on the mixer tank rods and surfaces – these dough residues should be put back into the dough mix (this is needed to ensure a more homogeneous dough mass, and better noodle quality).

Plastic spatula can be used to remove dough residues from the mixer tank surfaces.

Once the mixing is finished, dough may be put into a plastic bag for conditioning (for about 2 hours at 28 degrees Celsius) – this is recommended.

Otherwise, dough may also be transferred directly into a dough hopper for immediate noodle making.

transferring ramen dough from a mixer into a dough hopper

Transfer dough mix into a dough hopper, and place the hopper onto the ramen machine above the Rollers compartment.

Transfer a certain amount of dough from the hopper on top of the gap between Rollers (enough to cover it with dough).

The grid above the Rollers compartment serves to protect users from injury: while dough can be fed to Rollers through the grid, the machine will not operate if the grid is opened.

Using a handle on the front side of the ramen machine, set the gap between two Rollers to 1.5 mm (which is a standard Rollers gap width for medium hydration dough)

Once the rolling operation is started, Rollers will rotate inwards forming dough mix into a dough sheet.

Wrap a tip of the dough sheet onto a rolling pin as shown in the picture below. Then place the pin onto supports above the left-side Roller.

Keep feeding an appropriate amount of dough mix into the gap between Rollers.

After all dough mix was formed into a dough sheet, place the rolling pin onto the right side rolling pin supports above the Rollers compartment.

Dough sheet combination stage (recommended):

Take another pin, and evenly split the dough sheet onto two rolling pins.

splitting ramen dough sheet onto two rolling pins

After dividing the dough sheet into two parts of equal length onto two rolling pins, make a fold in the middle as shown in the picture below.

Set the gap between Rollers to 2 mm.

Explanation: the gap is usually set to a width that is 70% of the thickness of dough sheet to be passed through the Rollers. Because in this case we have two layers with a thickness of 1.5 mm, the gap is calculated as 3 mm X 0.7 = ~2 mm

Repeat wrapping / rolling procedures.

Combination process makes ramen dough sheet more firm and elastic, significantly improving final noodle quality.

Once a tip of the dough sheet was wrapped onto a rolling pin, and placed onto supports above the left side Roller, combination will proceed automatically.

If the dough sheet was not divided into completely equal parts, at the end of the Combination operation overlap the longer end over the shorter to ensure that the full length of the dough sheet is combined into a single double-layer sheet.

For the second Combination stage (recommended) set the gap between Rollers to 3 mm.

To prevent dough layers from sticking to each other, during the second (final) combination stage use automatic flour duster installed above the left side roller.

Dispensing amount should be adjusted according to the hydration level of dough (note: it may not be necessary to use flour duster when making low-hydration noodles).

After the the final combination, put the dough sheet into a plastic bag, tightly seal it, and let it stay for about 30 minutes at room temperature for better dough conditioning. At the dough sheet conditioning is over proceed to the Thinning operation.

how to make ramen noodles on a ramen machine

Make sure to measure dough sheet thickness after each thinning. 

In this example, after passing the dough sheet through a 2 mm gap, the sheet’s thickness turned out to be around 2.5 mm (dough thickness will usually be bigger than the nominal gap between Rollers).

measuring dough sheet thickness during production of ramen noodles on a ramen machine

Because in this example, the dough sheet will be cut into two different types of ramen noodles, after the first thinning we will divide it into two halves.

The first half will be cut using a square ramen cutter No. 18 (with a groove width of 1.7 mm). The number 1.5 mm given on the right side of the table in the picture below stands for the recommended final thickness of dough sheet.

This is premised on a standard square shape of ramen: noodle width will be determined by the width of grooves of a cutter installed into the machine during cutting (which is 1.7 mm), but the thickness will bounce back and become bigger than 1.5, finally reaching around 1.7, giving us square shaped noodles.

Measure the dough sheet thickness.

In our example, after passing the dough sheet through a 1.5 mm Rollers gap, the thickness turned to be 2 mm.

Set the Rollers gap to 1 mm.

Explanation: since our target thickness is 1.5 mm, based on the bounce back ratio observed during previous rounds of thinning, we can expect to achieve it by passing the sheet through a 1 mm gap.

For the second half of the dough sheet we will use a cutter No. 16 for round-shape noodles.

Since the recommended dough sheet thickness for the size 16 cutter is 1.7 mm, the noodle sheet can be cut immediately after passing it through a 1.5 mm Rollers gap.

Cutting procedures are the same as described above.
