Buckwheat Flour Milling Facilities

Yanagihara offers designs and construction for the purpose of productivity improvement and labor saving, from small-scale flour milling facilities where only one flour mill is installed, to large-scale flour milling plants where more than 20 are deployed.
We deliver a range of equipment according to our customers’ requests, including single-seated and multi-seated units, whole wheat flour milling or high-volume production with large-size rolls, as well as conventional transportation methods using elevating machines/screw conveyors or pneumatic transport (low and high density).

Filling and Sorting Process

This process removes large and small impurities and stones mixed in with unpolished buckwheat and polishes the skin to remove dirt. It is also a very important process in terms of reducing the number of bacteria.
The majority of large-scale flour milling facilities use air in large quantities to for careful selection, and using pneumatic transport between equipment.

  • Separator (with aspiration)

  • Small-sized sorting machine

  • Sorting machine (Scourer machine)

Decorticating Process

The two methods of removing husks of the unpolished buckwheat are; 1) breaking the husks and separating them, and 2) peeling the husks with as little breakage to the buckwheat as possible (nukimi, marunuki, or round grains). The latter method tends to be more often used these days, but we can propose appropriate technologies and equipment according to your budget and requests.

Flour Milling Process

The final step in the process from unpolished buckwheat to products. To ensure the quality of the products, first impurities and contaminants are removed, then they are stirred, mixed, color matched, and homogenized.

Product Management Process

The flour milling process can be roughly categorized into roll milling and stone milling. In both methods, we deliver reliable technology that has been refined over many years.

Separator (with Aspiration)

Eliminates large and small impurities while also removing light-ratio elements via aspiration.

Small Sorting Machine (SSM)

Combines a feeding machine and sorting machine in a set for small-scale milling plants or millers working from home. Used as part of a cycle for stone sorting machines and sorting machines, once loaded with unpolished rice it can automate the selection of time for stone removal and sorting according to the volume fed in.
Processing capacity: 200-300 kg per hour

Sorting Machine

Grinds the husks of unpolished buckwheat to remove dirt. We offer models for your processing volume and space, with space-saving large specifications from single-unit cyclic type to connective specifications for using three units.

Husking Sieve Type W640

A large three-step/four-type husking sieve, able to handle up to five types if dusting powder is included. Uses a grinding method enabling combination as round/granular.

Aspirator

A wind-powered ratio selector to service in place of previous winnowers, with a range of models to match the processing capacity.

Shifter

We have a variety of types of rotary motion shifters for multistep multi-type sorting.

Tanks

We manufacture a variety of tanks, including materials tanks, shredded flour tanks, hull tanks, and product tanks. The photo shows a product tank specification with screw discharge. Comes with a vibration motor to minimize sticking of contents to the walls and an inspection hatch for easy cleaning of the interior.
