High hydration wavy noodles with Cutter 20
Being a company that manufactures and sells noodle making machines for Ramen, Yamato can authoritatively state that No. 20 is the most frequently ordered variety of slitter cutters.
For those who are not familiar with the nomenclature, it should be added that a cutter’s number refers to the width (in millimetres) of grooves carved on a cutter’s blades which have a total width of 30 cm. Thus, No. 20 refers to a cutter with a groove width of 1.5 mm: 30 / 20 = 1.5 mm.
This cutter is especially popular with those ramen entrepreneurs who are still new to noodle business, and would like to be rather safe than sorry when choosing a cutter (especially if they are on a tight budged, and cannot afford to spend much on initial investment).
Cutter No.20 allows to produce noodles which are on a thinner side, but which are not necessarily might be considered as too thin. Thus, No. 20 has one of the widest operational scopes among other cutters, and is capable of producing noodles for the widest range of Ramen dishes.
While cutter of this size is most frequently used for noodles which are straight in shape and are made from medium hydration ratio dough, this does not mean that it cannot be used for noodles with different properties – for example, made from high-hydration dough, and with a wavy shape.
Such noodles can be used for a wide range of Ramen dishes, though are most suited for chintan variety of Ramen bowls based on shio– or shoyu-base motodare.
On September 24, 2021, join Yamato for a free online noodle workshop dedicated to production of high-hydration wavy noodles using a No.20 cutter on “Richmen” – a commercial Ramen making machine for restaurants and mini-factories.
In particular, we will cover such aspects as the most appropriate type of flour and other ingredients, as well as production-wise tips and advice for superb texture and an ability to remain in hot soup without getting soggy too quickly.

The workshop is Free, and its live broadcast is accessible by the link that will be sent to your email address after you sign up.
